川中地区含硫气田水闪蒸气脱硫除臭工艺应用现状与优化建议

Application Status and Optimization Suggestions of Flash Vapor Desulfurization and Deodorization Technology in Sulfur Gas Fields Water in Central Sichuan

含硫天然气田开发中产出的气田水逸散出的闪蒸气含有硫化氢、有机硫等恶臭污染物,影响站场周边环境空气质量,危害现场人员健康。因此,对含硫气田水逸散闪蒸气的有效治理是含硫气田开发安全、清洁生产的要求。文章结合当前国家大气污染防治政策和中国石油温室气体控排要求,对川中含硫气田水闪蒸气采取的脱硫除臭措施的适宜性进行分析,指出不同气田、不同阶段采用的脱硫除臭工艺的局限性。建议针对气田生产特点对含硫气田水闪蒸气治理工艺进行深入研究,在满足安全生产、避免公众环境投诉的条件下,积极落实国家节能提效、低碳排放政策,在新改扩建项目中因地制宜做出调整。

The flash gas escaping from the gas field water produced in the development of sulfur natural gas fields contain odorous pollutants such as hydrogen sulfide and organic sulfur, which affect the ambient air quality around the station and endanger the health of field personnel. Therefore, the effective control of the flash gas escaping from the sulfur gas field water produced is the requirement for the safe and clean production of the development of the sulfur natural gas field. In combination with the current national air pollution prevention and control policies, and the control requirements of greenhouse gas emission from China National Petroleum Corporation, the paper analyzed the suitability of the desulfurization and deodorization measures taken for the water flash in the sulfur natural gas field in central Sichuan. The limitations of desulfurization and deodorization processes used in different gas fields and different stages were pointed out. It was suggested to conduct in-depth research on the water flash gas treatment process in sulfur gas fields in terms of the production characteristics of gas fields. Under the conditions of satisfying production safety and avoiding public environmental complaints, the national policy of energy conservation and efficiency improvement and low carbon emission should be actively implemented, and some adjustments needed to be made according to local conditions in new reconstruction and expansion projects.
