- 摘要:
- 针对渤海某油田在脱硫过程中产生的严重硫垢沉积问题,以二甲基二硫醚(DMDS)为主剂,加入氢氧化钠(NaOH)、二甲基甲酰胺(DMF)和水进行复配得到复合硫溶剂,研究组分配比、药剂用量、溶解温度、溶解时间对溶硫率的影响,得出复合硫溶剂的最佳配比DMDS∶NaOH∶DMF∶水=1∶2∶4∶3,治理硫垢的最佳条件:药剂用量为硫垢重量的20倍,溶解温度为45℃,溶解时间为50 min,在此条件下,溶硫率可达到100 。现场条件模拟实验证实了该硫溶剂具有优异的除硫性能。
Aiming at the serious sulfur deposition of some oil fieldat Bohai sea，a new type of complex sulfur solvent has been compounded with dimethyl disulfide(DMDS) ，sodium hydroxide，dimethyl for mamide(DMF)and water.The influences of component ratio，sulfur solvent dosage，dissolving temperature anddissolving time onmelting sulfur rate are investigated.The optimum conditions are as follow，the mass ratio of DMDS，Na0H，DMFand water is 1 :2 :4 :3.The sulfur solvent dosage is 20 times of the sulfur deposition，and dissolving temperature is 45℃ cand dissolving time is 50 minutes.Under the optimum conditions， the melting sulfur rate reaches 100%.The complex sulfur solvent shows the excellent sulfur melting performance under the simulated fie1d conditions.
