Carbon dioxide removal technologies for hydrocarbon gases (associated gas, coal gas, biogas)

  • undefined

Detailed Introduction

Methane is a combustible gas with a high calorific value. Depending on actual needs, chemical adsorption can be used to decarbonize and purify gases containing methane and other high-calorific hydrocarbon gases, turning them into higher-grade natural gas. This can then be directly integrated into the natural gas supply network or compressed and liquefied to become compressed natural gas (CNG) or liquefied natural gas (LNG), resulting in better economic benefits. The introduction of decarbonization and purification technology in projects utilizing associated gas, wellhead gas, and biogas not only improves the overall technical level of the project but also generates high financial returns through the sale of the purified natural gas. Based on the operation of large-scale domestic projects, good economic benefits can be achieved whether the gas is sold externally or used internally.
