摘 要:人类利用能源的发展趋势是从高碳走向低碳,未来30年受能源政策以及相关产业技术革命等因素的驱动,天然气在新能源中的地位显著提升,天然气的净化、储存与运输备受关注。天然气脱水工艺流程是油气田生产过程中的重要环节,以西北某气田天然气三甘醇脱水处理工艺为例,运用Aspen HYSYS过程仿真软件,探讨天然气三甘醇脱水工艺的影响因素,建立三甘醇脱水系统的碳排放优化模型,并进行系统能耗及碳排放核算的计算模拟。天然气三甘醇脱水系统优化后碳排放降低了约3.6%,能耗降低了约6.7%,继而优化了整个脱水流程,降低了单位经营生产成本,达到节能减排的绿色油田生产建设目的。The trend of human energy utilization is heading from high-carbon footprint toward low-carbon footprint development. In the next 30 years, driven by factors such as energy policy and related industrial technological revolution, the role of natural gas will be significantly uplifted. The purification, storage and transportation of natural gas have attracted widespread attention. The natural gas dehydration process is an important link in the production process of oil and gas fields. The triethylene glycol(TEG) natural gas dehydration treatment process of a gas field in Northwest China is taken as an example. Using the Aspen HYSYS process simulation software, the influencing factors of the triethylene glycol dehydration process were studied and the carbon emission optimization model of the triethylene glycol dehydration system was established. The HYSYS model was used to simulate and calculate the system energy consumption and carbon emission. After optimization, the TEG dehydration system has reduced carbon emissions by about 3.6% and energy consumption by about 6.7%. The entire dehydration process was then further optimized to lower the unit operation and production costs in order to achieve energy saving and emission reduction in the development of green oil field operations.
