Abstract

The present disclosure provides a method for processing an acid gas, comprising: using a processor 1 for receiving and processing the acid gas to obtain a gas phase stream 1 and a liquid phase stream 2, wherein the stream 2 is partially or completely recycled to the processor 1; using a processor 2 for processing the stream 1 from the processor 1 to obtain a gas phase stream 3 and a liquid phase stream 4; using a processor 3 for processing the stream 3 from the processor 2 to obtain a gas phase stream 5 and a liquid phase stream 6; and using a processor 4 for receiving the stream 43 from the processor 2 and using the stream 43 as a processing solution for processing the stream 5 from the processor 3 to obtain a gas phase stream 7 and a liquid phase stream 8, which can be divided into two sub-streams including a stream 81 and a stream 82. The present disclosure further provides an apparatus for processing an acid gas.
