倘若压缩气体含有H2S的酸性气体,会产生严重的腐蚀,侵蚀压缩机巴比特合金衬里的密封圈而污染密封油。压缩机密封油经过内部密封套圈与压缩气体接触,并在酸性油排出槽的各个部位吸收H2S。防止腐蚀压缩机密封元件的三种有效方法是:喷射缓冲气体,放弃酸性密封油或净化酸性密封油。第一种方法需要一些费用,要可靠的供给缓冲喷射气体。但是有效地供给缓冲气体常常是化费大,或者是不可靠的。放弃酸性密封油,在正常的时候,每天一台工作的压缩机要排出20加仑（75.7升）,在不正常的时候,其量高达每天几百加仑,而且将出现严重的污染环境和处理费用问题。倘若排入暗沟还会造成扫除流出物的设备和操作费用。酸性密
If the compressed gas containing acid gas H2S, will have serious corrosion, erosion of the compressor lining the liner of the oil and pollute the seal oil seal. The compressor seal oil comes in contact with the compressed gas through the internal seal collar and absorbs H2S in all parts of the sour oil drain tank. Three effective ways to prevent corrosion of compressor seal components are: Spray buffer gas, give acid seal oil, or purify acid seal oil. The first method requires some cost to provide a reliable supply of buffered jet gas. However, the efficient supply of buffer gas is often expensive or not reliable. Abandonment of acid seal oil, in normal times, a compressor working day to discharge 20 gallons (75.7 liters), in abnormal times, the amount of up to several hundred gallons per day, and there will be a serious pollution of the environment and processing costs problem. Drainage into the undercut can also result in equipment and operating costs for cleaning up the effluent. Acid dense
