1. A method for processing an acid gas, comprising:
using a first processor 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 first processor, using a second processor for processing the stream 1 from the first processor to obtain a gas phase stream 3 and a liquid phase stream 4, which is divided into three sub-streams including a stream 41, a stream 42, and a stream 43, wherein the stream 41 is returned to the first processor as a processing solution used for processing the acid gas, and the stream 42 is recycled to the second processor, using a third processor for processing the stream 3 from the second processor to obtain a gas phase stream 5 and a liquid phase stream 6, which is divided into two sub-streams including a stream 61 and a stream 62, wherein the stream 61 is returned to the second processor as a processing solution used for processing the stream 1, and the stream 62 is recycled to the third processor, and using a fourth processor for receiving the stream 43 from the second processor and using the stream 43 as a processing solution for processing the stream 5 from the third processor 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, wherein the stream 81 is returned to the third processor as a processing solution, and the stream 82 is recycled to the fourth processor. |
