Unlike aqueous amine processes, the process removes carbonyl sulfide, mercaptan derivatives, and other organic sulfur compounds to stringent total sulfur specifications. Further, the “natural gas” definition specifies that H Sulfinol-M is used when a higher degree of hydrogen sulfide selectivity is needed. It'll be tough to turn this around by then without the cooperation of your compressor packaging vendor. Capacity. provided Permittee receives and maintains quarterly records of the vendor’s analysis, and the data is of sufficient quality to yield further analysis as required above. The product gas must meet the heating values or Wobbe Indexes specifications, which are required to ensure optimum operation of gas turbines and combustion equipment to minimize emissions. Even routine maintenance of the compressor with top nozzles will take two and a half days to remove, replace, and test that high-pressure gas piping. However, if stringent sulfur specification must be met, the lean amine must be raised to a higher tray location, which would add more contacting stages but would also reduce the amount of CO2 slippage. Many process factors should be considered when selecting an amine for a sweetening application as outlined here: The initial selection should be based on the pressure and acid gas content of the sour gas as well as the purity specification for the product gas. The process is used for the removal of hydrogen sulfide, carbonyl sulfide, mercaptan derivatives, other organic sulfur compounds and all or part of the carbon dioxide from natural, synthetic, and refinery gases. However, advances in enhanced glycol dehydration processes, such as the DRIZO system, can solve the problem by production of a BTEX hydrocarbon liquid. Gas must be of merchantable quality, and commercially free from all water, sand and other objectionable fluids, bacteria, solids and gases. James G. Speight Ph.D., D.Sc., in Natural Gas (Second Edition), 2019. Sales gas transmission will be discussed in detail in Chapter 15. As for the use of silica gel dehydration process, because of its limited short cycle time, it is more suitable for polishing services, such as membrane separator pretreatment, and fuel gas conditioning rather than feed gas to a gas processing plant. It's two doors down the hall to the left. Molecular sieves are selective and do not appreciably adsorb BTEX components hence avoiding the emission problems in conventional TEG dehydration units. The McCarty Road landfill is owned and operated by Republic Services and is one of the largest waste disposal facilities in Texas. The standard El Dinero design calls for bottom nozzles and that's what it's going to be—period.”, “Dip, you know what this will do to the schedule. “Pipeline- quality” gas came to be defined as natural gas (1) within + / - 5 percent of the heating value of pure methane, or 1,010 Btu per cubic foot under standard atmospheric conditions, and (2) free of water and toxic or corrosive contaminants.8 It is important to recognize the definitions and specifications of the treated gas and product specifications. Value Unit Monitoring Frequency* Recommended Test . Submit a Change Request Form, complete with drawings, a bill of materials, vendor prices, and the schedule impact. Typical pipeline gas specifications are shown in Table 4.1. TEG dehydration unit is lower in Capital Expenditure (CAPEX) and Operating Expenditure (OPEX) than the molecular sieve unit, especially for offshore installation where plot space is limited. 2 % vol Continuous D1945 Containers may explode when heated. The new Mid-Michigan Pipeline … Pipeline-quality natural gas consists of at least 95% methane and trace amounts of other gases. Typical Pipeline Gas Specifications. The mercaptans are concentrated in the regeneration gas, and can be selectively removed using a physical solvent process, such as the DEPG process. If hydrocarbons dew point control is required, cooling with inhibitor, such as the use of ethylene glycol injection with propane chilling or the use of silica gel can be suitable. Don't you like to save the company money?”, “Your stupid cost-saving ideas will cost us more in downtime than you ever dreamed. Gas dehydration technology selection. Multiple lean amine feed points can be installed in the absorber to provide the flexibility for selective CO2 removal. Some ethane is often left in the processed natural gas. Utility generators have a need to know the expected range of quality of the fuel being delivered to them The C5+ components can be exported to refineries as a blending stock for gasoline. Typical glycol dehydration process is suitable for meeting pipeline gas specification as low as −40°F and is more economical than molecular sieves technology. Raw natural gas stream must be treated to comply with emissions regulations and pipeline gas specifications. Use of Only Pipeline Quality Natural Gas as FuelNatural gas combustion when combined with good combustion practices generates less emissions than other fuels.Runtime Limitations Limiting the operation of a source where practical to eliminate excess emissions. The process sequence-Sulfinol/Claus/SCOT can be used advantageously with an integrated Sulfinol system that handles selective hydrogen sulfide removal upstream and the SCOT process that treats the Claus offgas. The natural gas dehydration process is selected based on the water dew point requirements, as shown in Fig. It is important to recognize the definitions and specifications of the treated gas and product specifications. Molecular sieves are selective and do not appreciably adsorb BTEX components hence avoiding the emissions problem in conventional TEG dehydration unit. The specifications are to ensure gas qualities and provide a clean and safe fuel gas to the consumers. The concentrations of the amine and the physical solvent vary with the type of feed gas in each application. There are other considerations that may favor the use of molecular sieves. “Sara, do you have an office where Dip and I can talk?”, “Sure, use the table in my office. Section 10.8 treats issues related to natural gas storage: capacity Table 1.2. The actual chemical formulation is customized for each application. DGA, despite a high heat of reaction, has a very high gas carrying capacity that usually produces very reasonable net energy requirements. The acceptance of biogas upgrading technology which purifies raw biogas to Pipeline Quality Gas (natural gas pipeline quality) and enables AD plant operators to inject biomethane gas to grid is rising.. Benefits of Upgrading to Pipeline Quality Gas. Howe… It will make the foundation less complicated and reduce the structural costs.”. Molecular sieves can be designed to remove mercaptans to meet the sulfur specifications. The solvent consists of an aqueous amine and sulfolane. Refinery fuel gas and gas pipeline specifications, such as 40 ppm v/v total sulfur and 100 ppm v/v hydrogen sulfide are readily attained. Enbridge: The largest energy infrastructure company in North America. that has been upgraded for use in place of fossil natural gas. A TEG dehydration unit is lower in CAPEX and OPEX than the molecular sieve unit, especially for offshore installation where plot space is limited. Gas dehydration technology selection. You'd better talk to Chet.”. Safety assurance is dependent on the quality of the work resulting from carrying out those procedures and practices. However, continuous monitoring is not always feasible and offline (or laboratory) testing can be used in its place. Molecular sieves can be designed to remove mercaptans to meet the sulfur specifications. If dehydration is required only to meet the pipeline specification of 4–7 lb/MMscf, any of the previously mentioned processes can be applicable. Sometimes a slight change in the product specifications may have significant impacts on the treatment and processing options, which will affect the cost and complexity of the gas plant. An improved application is to selectively remove hydrogen sulfide, carbonyl sulfide, mercaptan derivatives, and other organic sulfur compounds for pipeline specification, while coabsorbing only part of the carbon dioxide. Ethane can be used as a feedstock to petrochemical plants. The Y-Grade liquids must be free from sand, dust, gums, gum-producing substances, oil, glycol, inhibitor, amine, caustics, chlorides, oxygenates, heavy metals, and any other contaminants or additive to the product used to enhance the ability to meet specifications. … The C5+ components can be exported to refineries as a blending stock for gasoline. This is particularly useful in tail gas treating unit operation which requires maximum slippage of CO 2 , and moving the feed location to a lower location will help to concentrate H 2 S content in the acid gas to the Claus sulfur recovery unit. It looks like we can save $400,000 to $500,000 by using a compressor with the inlet and outlet nozzles coming from the top of the compressor casing. Saeid Mokhatab, ... John Y. Mak, in Handbook of Natural Gas Transmission and Processing (Fourth Edition), 2019. Typical glycol dehydration process is suitable for meeting pipeline gas specification; as low as −40 °F and is more economical than molecular sieves technology. The removed natural gas liquids (NGLs) can typically command a higher value than natural gas for the same heating value. When the sales gas reaches a local gas utility, it normally passes through a gate station to serve three purposes: (1) reducing the pressure in the line from transmission levels to distribution levels, (2) adding an odorant so that consumers can smell even small quantities of gas, and (3) measuring the flow rate of the gas to determine the amount delivered to the utility. Raw natural gas streams must be treated to comply with emissions, regulations, and pipeline gas specifications. However, MEA is still used for plants where the inlet gas pressure is low and pipeline specification gas or total removal of the acid gases is required. When the gas is high in heavy hydrocarbon content, it may exceed the maximum allowable British thermal unit (Btu) specification. The separated NGL are called natural gas plant liquids (NGPL), and the processed natural gas is called dry, consumer-grade, or pipeline quality natural gas. Alireza Bahadori Ph.D., in Natural Gas Processing, 2014. The Department has determined that the burning of Pipeline Quality Natural Gas constitutes BACT for PM and SOX.IV. Natural gas can be combusted for space or water heating, used in turbines to generate electricity, or used as a transportation fuel. Natural gas processing plants separate hydrocarbon gas liquids, nonhydrocarbon gases, and water from the natural gas before the natural gas is delivered into a mainline transmission system. Solid desiccant dehydrators are chosen for deep dehydration to meet a low water dew point for NGL recovery or LNG production. PlummerJr., in Project Engineering, 2007. The DEA, is used for its lower heats of reaction, higher acid gas carrying capacity, and resultant lower energy requirements. “Sara, I don't think we need to go any further with the design review until we get this nozzle issue resolved. Propane and butane can be sold as liquefied petroleum gas (LPG). All contents of the lawinsider.com excluding publicly sourced documents are Copyright © 2013-. gas was converted into the 18.9 Tcf of dry natural gas that was put into the pipeline system. The United States has 11 distinct natural gas pipeline corridors: five originate in the Southwest, four deliver natural gas from Canada, and two extend from the Rocky Mountain region. Ethane can be used as feedstock to petrochemical plants. Deep removal of carbon dioxide removal for liquefied natural gas plants is another application, as well as bulk carbon dioxide removal with flash regeneration of the solvent. The process selection can be quite straight forward. The Sulfinol process, developed in the early 1960s, is a combination process that uses a mixture of amines and a physical solvent. The Sulfinol mixed solvent consists of a chemical-reacting alkanolamine, water, and physical solvent sulfolane (tetra-hydrothiophene dioxide). Edgar had just finished summing up his preliminary conclusions on the client's contractual design basis. After the raw gas has been processed to meet pipeline gas specifications, the marketable (sales) gas is transported through pipelines to industrial and residential consumers or to underground storage facilities for later delivery to these consumers as demand dictates. It can also be accomplished with TEG dehydration unit followed by propane chilling. The natural gas dehydration process is selected based on the water dew point requirements, as shown in Figure 7-20. It can also be accomplished with a TEG dehydration unit followed by propane chilling. Typical pipeline gas specifications. That's your problem.” Dip got up from the table and left the building. 9.20. Ruptured cylinders may rocket. The mercaptan components can then be converted to sulfur in a Claus sulfur recovery unit to eliminate sulfur emissions. This NAESB-compliant web site will allow you to select a pipeline group/pipeline from the menu bar on the left, and easily navigate to the section of this site that interests you by selecting the appropriate section from the expanded menu. The definitions of “natural gas” and “pipeline natural gas” in § 72.2 also limit the hydrogen sulfide (H 2S) content of these fuels to <1.0 gr/100 scf (for natural gas) and < 0.3 gr/100 scf (for pipeline natural gas). However, advances in enhanced glycol dehydration processes, such as the DRIZO system, can solve the problem by production of a BTEX hydrocarbon liquid. Continuous D1945 / D7164 Carbon Dioxide CO. 2. The Sulfinol-D process uses DIPA, while Sulfinol-M uses MDEA. This is particularly useful in tail gas treating unit operation which requires maximum slippage of CO2, and moving the feed location to a lower location will help to concentrate H2S content in the acid gas to the Claus sulfur recovery unit. Sometimes a slight change on the product specifications may have significant impacts on the treatment and processing options, which will affect the cost and complexity of the gas plant. Raw natural gas stream must be treated to comply with emissions regulations and pipeline gas specifications. Pipeline Quality Natural Gas: during natural gas operations, combust only pipeline quality natural gas. Sulfinol has a good affinity for most of the acid gases and has the ability to release these gases in the regenerator upon pressure reduction and heat application. When the gas is high in heavy hydrocarbon contents, they must be removed to meet the heating value specification. 3. Background Natural gas processing begins at the wellhead (Figure 1). 10.7 describes the detailed characterization of the natural gas pipeline network, the pipeline capacity expansion logic, and the assumptions and procedures used to capture pipeline transportation costs. Pipeline operators also require the product gas to be interchangeable and similar in properties with existing pipeline gas. The characteristics of various types of natural gas liquid (NGL) products can be found in the GPSA (2004) Engineering Data Book. With Natural Gas, due to the nature of the product and the transportation mechanism, the quality of the delivered product is primarily determined by the pipeline. Sara thought Arlo looked like he had just come from a traffic accident. Pollutant concentration monitor means that component of the continuous emission monitoring system that measures the concentration of a pollutant in a unit 's flue gas. Note should be made that sometimes a slight change on the product specifications may have significant impacts on the processing options, which will affect the cost and complexity of the gas processing plant. However, complete removal of carbonyl sulfide by Sulfinol-D cannot be guaranteed. “Pipeline quality” gas cam to be defined as natural gas (1) within +/- 5% of the heating value of pure methane or 1,010 Btu per cubic foot under standard atmospheric conditions, and (2) free of water and toxic or corrosive contaminants.” *The FPC has been replaced with the Federal Energy Regulatory Commission (FERC) MDEA is currently best known for its ability to preferentially absorb H2S. When operating under suitable conditions, it is capable of removing twice as much acid gas as a 20% MEA solution. Typical pipeline gas specifications are shown in Table 3-1. DO NOT EXTINGUISH A LEAKING GAS FIRE UNLESS LEAK CAN BE STOPPED. Solid desiccant dehydrators are chosen for deep dehydration to meet a low water dew point for NGL recovery or LNG production. The process is in many respects identical to the familiar amine method and its equipment components similar to those found in amine units. I won't have it! The characteristics of various types of natural gas liquid (NGL) products can be found in GPSA Engineering Data Book (2004). The pipeline gas specification was incomplete, but Johnny Bent, the Project Engineer for the pipeline tie-in, had agreed to call a meeting to resolve the matter. The specifications are to ensure gas qualities and provide a clean and safe fuel gas to the consumers. The mercaptan components can then be converted to sulfur in a Claus sulfur recovery unit to eliminate sulfur emissions. I need it by October 28th.”, “OK, Arlo, but that's only two weeks. For water dew pointing lower than −40°F and down to −80°F, the enhanced TEG dehydration process, such as DRIZO, is suitable. Pipeline operators also require the product gas to be interchangeable and similar in properties with existing pipeline gas.
