pipeline quality natural gas

That's over $1 million in lost gas sales right there. 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. Solid desiccant dehydrators are chosen for deep dehydration to meet a low water dew point for NGL recovery or LNG production. Solid desiccant dehydrators are chosen for deep dehydration to meet a low water dew point for NGL recovery or LNG production. The Typical pipeline gas specifications are shown in Table 4.1. The mercaptans are concentrated in the regeneration gas, and can be selectively removed using a physical solvent process, such as the DEPG process. Gas must be of merchantable quality, and commercially free from all water, sand and other objectionable fluids, bacteria, solids and gases. The process selection can be quite straight forward. It's two doors down the hall to the left. Y-grade NGL specifications (Mokhatab et al., 2015). Propane and butane can be sold as liquefied petroleum gas (LPG). The main difference is that while the conventional amine process employs a fairly diluted concentration of amine in water, removing the acid gas by chemical reaction, the Sulfinol system uses a mixture of highly concentrated amine and a physical solvent removing the acid gases by physical and chemical reactions. Some wellhead natural gas is sufficiently dry and satisfies pipeline transportation standards without processing. Table 4.1. Pipeline Quality Natural Gas shall be exempt from this requirement (III.A.1.iii.) 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. Common Sulfinol mixtures are in the range of 40% amine (also called DIPA), 40% sulfolane (an organic solvent), and 20% water. 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. It'll be tough to turn this around by then without the cooperation of your compressor packaging vendor. of VOC species in the natural gas fuel (e.g., formaldehyde and benzene) may also contribute to VOC emissions if they are not completely combusted in the boiler. Preventative Maintenance – This involves the testing of valves and the removal of surface impediments to pipeline inspection. Figure 9.20. ScienceDirect ® is a registered trademark of Elsevier B.V.

Capacity. 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. CLEANING BIOGAS TO PIPELINE QUALITY STANDARDS Several methods and technologies are available to condition and upgrade biogas into renewable natural gas (RNG) and remove constituents of concern. 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. 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. There are other considerations that may favor the use of molecular sieves. Typical glycol dehydration process is suitable for meeting pipeline gas specification; as low as −40 °F and is more economical than molecular sieves technology. William A. Poe, Saeid Mokhatab, in Modeling, Control, and Optimization of Natural Gas Processing Plants, 2017. Molecular sieves can be designed to remove mercaptans to meet the sulfur specifications. The characteristics of various types of natural gas liquid (NGL) products can be found in the GPSA (2004) Engineering Data Book.
