KED India has extensive experience in providing engineering design of natural gas plants from the wellhead to the pipeline. We have experience in working on following type of projects:
This process is also known as Amine Treating and Acid Gas Removal. A typical amine gas treating process includes an absorber and a regeneration tower. It is essential to remove sour gases such as H2S and CO2 from the natural gas stream to avoid corrosion issues with downstream processes and equipment. The most commonly used Amines include Diethanolamine (DEA), Monoethanolamine (MEA), Methyldiethanolamine (MDEA).
Triethylene glycol (TEG) is the most commonly used to remove water from the natural gas stream in order to meet the pipeline quality standard gas. This process is required to prevent hydrates formation at low temperatures or corrosion problems due to the presence of carbon dioxide or hydrogen sulfide (regularly found in natural gas). Glycol dehydration units depress the hydrate formation point of the gas through water removal.
Natural gas coming directly from a well contains many natural gas liquids that are commonly removed. In most instances, natural gas liquids (NGLs) have a higher value as separate products, and it is thus economical to remove them from the gas stream. The removal of natural gas liquids usually takes place in a relatively centralized processing plant and uses techniques similar to those used to dehydrate natural gas. It is also important to remove NGL's which could potentially condense and cause issues in transmission of the gas.
