对采用临氢降凝装置生产精制柴油进行了可行性分析,试生产精制柴油也取得了较好的效果:柴油产品收率98.55%,汽油收率0.62%,脱硫率92%,装置负荷率93.2%,在解决产品流程负荷的两种方案中作者认为按照10%-20%的比例在原料中掺炼粗汽油的方案是最佳方案。 相似文献

由于我国各炼厂目前生产的柴油产品(尤其是低凝柴油)远不能满足市场需求,加之柴油吨油利润明显高于汽油吨油利润,因此,各炼厂努力提高柴汽比成为增加本厂经济效益的有效手段。基于此,玉门炼油化工总厂于1999年将原150kt/a柴油加氢精制装置改造为100kt/a柴油临氢降凝装置,并使用抚研院的FDW-1降凝催化剂。该装置建成后运行平稳,成为增产柴油的有效手段。 相似文献

Taking into account the actual crude slate processed at the refinery, it is necessary to make reasonable combination and blending of crude oils. In order to cope with high wax content in diesel fuel it is proposed to appropriately regulate the refining process scheme and add additives to refined products. This measure after being applied in the production practice has brought about good results and has met the needs of commercial production. 相似文献

Emulsification is an unwanted phenomenon in the refining of highly acidic oil by alkali washing electrorefining. In this work, a novel microwave demulsification method is applied in the removing of naphthenic acid. The internal heating is attributed to molecular rotation and ionic conduction. The decrease of Zeta-potential of interface and the viscosity of diesel oil are responsible for the acceleration of separation of naphthenic acid and demulsification with microwave irradiation. The results show that both the separation efficiency and the demulsification rate are maximum when the optimum microwave irradiation power, exposure time, and irradiation pressure are deemed to be 375 W, 5 min, and 0.05 MPa, respectively. 相似文献

Abstract Coker diesel oil is refined by extraction of furfural adding assistant in this study. The influences of different operating conditions, such as the amount of assistant, the solvent/oil ratio, the refining temperature, the refining time, and the settlement time, on the quality of refined oil were investigated in batch experiments, and suitable operating conditions under which coker diesel oil refined can meet product qualify specifications of 0# diesel oil were given out. These had been verified in continuous experiments, i.e., the amount of additive was 8 g/kg, the refining temperature was 70°C, the solvent/oil ratio (v) was 1.0, the settlement time was 30 min, and refining time was 30 min. The experimental results show that the influence of basic nitride on the stability of coker diesel oil is predominant. 相似文献
