摘要
以中海油环烷基常二线和减三线馏分油及其混合油作为原料,通过高压加氢处理、糠醛精制组合工艺制备变压器油和环保橡胶油。结果表明,常二线馏分油单独进料,通过单段高压加氢处理工艺可得到满足GB 2536—2011的变压器油。减三线馏分油单独进料,通过单段高压加氢处理工艺可直接生产CA为10%的环保橡胶油。2种馏分油混合进料,通过高压加氢处理和糠醛精制组合工艺可生产CA超过25%的高芳环保橡胶油,生产的变压器油CA较高,与深度精制石蜡基变压器油调和可得到满足GB 2536—2011的变压器油。2种馏分油混合进料可避免因原料切换产生过渡油,充分释放加工能力,提高装置利用率。
The transformer oil and environmental friendly oil both with high CAvalue can be produced via high pressure hydrogenation combining with furfural refining process by using CNOOC-made naphthenic atmospheric 2^#line and vacuum 3^#line distillates as raw materials. It is found from the research results that atmospheric 2^#line distillate alone can be processed by single stage high pressure hydrogenation method into transformer oil than can meet GB 2536—2011,vacuum 3#line distillate alone can be processed by single stage high pressure hydrogenation method to produce environmental friendly rubber oil with a CAvalue of 10%. The high aromatic hydrocarbons-containing environmental friendly rubber oil with a CAvalue more than 25% can be produced by the combined process with hydrogenation and furfural refining,using mixed atmospheric 2#line and vacuum 3#line distillate as raw materials.The combined process with mixed distillates fed can produce transformer oil with high CAvalue,which can be blended with deep refining paraffin-based transformer oil to meet GB 2536—2011 standard.The mixed distillate feed can avoid the production of transition oil caused by raw material switching,utilize fully the processing capacity and improve the utilization rate of facility.
