| 摘要: |
| 针对我国西部某油田A井区高含硫的问题,利用专业软件模拟和相关实验开展了井场原油气提脱硫技术和化学脱硫技术的研究。在模拟A井气提脱硫的基础上,得出气提法的优化参数为塔压0.3 MPa,6层塔板,气提气量和塔底重沸器温度依据气提气充足与否和耗能情况进行调节,气提气量控制在4.7~6.1 m3/t,相应的塔底重沸器温度为152.0~41.6 ℃。对于化学脱硫,通过实验筛选出了适用于A井、主要成分为二异丙基合成物的脱硫剂,并评价了用量、作用时间、含水率、温度等因素对其脱硫效果的影响。 |

| Abstract: |
| The existence of hydrogen sulfide in crude oil will cause the corrosion of the equipment,lower oil quality and a serious threat to personal safety. Therefore, it is important to remove hydrogen sulfide in the process of crude oil production. To solve the problem of high-sulfur crude oil produced in A well area in the western China, the gas stripping method and the chemical method have both been analyzed. Based on the stimulation of stripping process, the optimized parameters of gas stripping are obtained, namely tower pressure is 0.3 MPa, plate number is 6, stripping gas is 4.7-6.1 m3/t, and reboiler temperature is 152.0-41.6 ℃ , the amount of stripping gas and the reboiler temperature are adjusted according to the adequacy of gas and the energy consumption. The desulfurizer mainly composed of two isopropyl complexes has been screened out and the effect of dosage, operating time, water content, temperature on the desulfurization have also been evaluated. |
