Deacidification treatment (CO2, H2S) of natural gas and coalbed methane is carried out by using activated MDEA and formula MDEA solution, and the purified gas meets the requirements of commercial natural gas index; pretreatment of liquefied natural gas and cryogenic natural gas meets the requirements of pretreatment index, and the CO2 content is less than 50ppmv and 20ppmv respectively (index requirements of ethane recovery unit).
The construction mode of modular design and factory prefabricated on-site assembly is: quality, safety and reliability; shorten the construction period and ensure the progress of the project; reduce construction costs; save land; overall disassembly and assembly are convenient.
