CN104923027A 一种酸气处理封存工艺方法 无效 - 驳回

一种酸气处理封存工艺方法
摘要：
本发明提供一种酸气处理封存工艺方法，酸气经过分离将待处理的酸气进入酸气分离器进行初步分离；进入多级压缩机进行增压，在级间进入脱水装置进行脱水处理，脱完水后继续进入多级压缩机入口进行增压，增压至合适输送压力（10-20MPa），后进入酸气输送管道输送至回注井回注到地层，这种全新的处理工艺，通过对酸气进行增压、脱水和管道输送回注到合适地层，较传统的酸气处理工艺工艺流程简单，设备少，全密闭操作，能很好的适应酸气负荷的变化，保证运行安全。酸气通过密闭工艺输送全部注入地层真正做到H2S和CO2的零排放。
摘要（英）：

The invention provides a process method for treating and sealing acid gas. The method comprises the following steps: preliminarily separating the acid gas to be treated in an acid gas separator through separation; pressurizing the acid gas through a multi-stage compressor, dehydrating the acid gas in a dehydration device at an inter-stage, continuously pressurizing the dehydrated acid gas from an inlet of the multi-stage compressor to an appropriate conveying pressure (10-20MPa), conveying the acid gas to a reinjection well through an acid gas conveying pipeline, and re-injecting the acid gas to a ground layer. According to the brand new treatment process, the acid gas is pressurized, dehydrated, conveyed through the pipeline and re-injected to the appropriate ground layer. Compared with a conventional acid gas treatment process, the brand new treatment process has the advantages that the flow is simple, the number of machine is small, fully-closed operation is carried out, the process can well adapt to the change of an acid gas load, and the operation safety is ensured. The acid gas is conveyed through a closed process and is fully injected to the ground layer to truly achieve zero emission of H2S and CO2.
