摘要：

Natural gas is a kind of clean energy with high calorific value, but raw natural gas contains a certain amount of acid gas CO2, which will cause problems like heating value reduction and pipeline corrosion. Therefore, it is necessary to remove CO2 from natural gas before subsequent transportation and utilization. This article introduces four decarburization technologies: cryogenic distillation, solvent absorption, adsorption and membrane separation. The process characteristics and typical industrial applications of each technology are analyzed in details and compared from the aspects of feed conditions of raw gas, removal efficiency, energy consumption and cost efficiency, which is of great engineering significance and provides guidance for the selection of separation processes in different actual conditions. Membrane separation technology has certain advantages of small equipment foot print, low energy consumption and high-cost efficiency. Moreover, the flexibility and adjustability of stages in membrane process enables it with high CO2 removal rate and low hydrocarbon loss. Therefore, membrane separation technology exhibits good development and application prospects, which is especially suitable for space-limited applications, such as CO2 removal from natural gas on offshore platform. © 2021, Editorial Board of CIESC Journal.
