摘要结合已有的原油负压稳定和气提脱硫工艺，通过工艺评价分析，创新设计负压稳定气提脱硫一体化处理工艺，在同一套装置中实现原油稳定和脱硫“一塔双效”。工业应用实践表明，原油稳定深度较单纯的负压稳定工艺提高10%以上；原油中H2S一次性脱出率90%以上，较气提脱硫工艺提升 30%以上。该设计工艺达到了降低油气损耗、减少脱硫剂加注成本、保护环境和降低生产安全风险的目的。

Abstract: Combined with existing negative pressure stabilization and gas stripping desulfurization process of crude oil , through the analysis of the process evaluation , the negative pressure stability and gas stripping desulfurization integration process was designed innovatively , which realized the crude oil stability and the desulfurization in the same set of devices . The industrial application practice showed that compared with the negative pressure stabilization process , the stable oil depth increased by more than 10% , the one-time emergence rate of H:S in crude oil reached 90% above, which increased more than 30% compared with the gas stripping desulfurization process . The design process reduced the loss of oil and gas and the desulfurizer cost , which achieved the purpose of environment protection and safety risk reduction .
Key words: negative pressure crude oil stabilization , gas stripping desulfurization, integrated process
原油在集输处理和储存过程中，较轻组分大量挥发易造成原油损耗和环境污染。原油稳定是通过闪蒸法或分馏法脱除原油中易挥发的轻烃成分（主要是C1 ～C4），降低储存温度下的饱和蒸气压，减少原油在储运环节的挥发损失，对于稠油，通常采用负压稳定工

艺。若原油中含有H2S，可通过适当的稳定塔优化设计将溶解在原油中的H:S脱出到气相，避免H:S 在后续原油储运环节逸出到大气[2-3]。在降低油气资源损耗的同时，既保护了环境，又降低了后续储运过程中的火险等危害因素，增加了油气储运过程的安全
