环烷基蜡油生产橡胶填充油的工艺对比

采用不同工艺加工环烷基蜡油生产橡胶填充油(简称橡胶油),对多种工艺进行了研究和分析,结果表明:一段高压加氢工艺可直接生产芳碳率(CA)为12%左右的环保橡胶油;全氢型流程(加氢处理-临氢降凝-加氢补充精制)对原料适应能力强,可生产洁净的低芳橡胶油;加氢脱酸与糠醛精制组合工艺可生产CA为12%左右的环保橡胶油;高压加氢处理与糠醛精制组合工艺可生产CA为21%~27%的环保橡胶油,并可根据产品需求灵活调整生产方案,该工艺与全氢型工艺耦合时,产品种类更丰富,生产调整更灵活。以上经验可为润滑油型炼油厂在升级改造和新建装置时提供参考。

COMPARISON OF PROCESSES FOR RUBBER EXTENDER OIL DERIVED FROM NAPHTHENIC VGO

Rubber extender oil(rubber oil) manufactured from naphthenic VGO through different processes were investigated. The results illustrated that VGO high pressure hydrotreating process could directly produce environment-friendly rubber oil with aromatic-carbon ratio(CA) of 12%. The full-hydrogenation (hydrotreating-hydrodewaxing-hydrofinishing) process has strong adaptability to raw materials and could produce clean rubber oils with very low aromatics content. Combination process of hydrodeacidification and furfural extraction could produce environment-friendly rubber oil with CA of about 12%. environment-friendly rubber oil with CA of 21%-27% could be produced by the combined process of hydrotreating and furfural refining, which could adjust the production scheme flexibly according to product demand. The types of products were more abundant and the production adjustment was more flexible when the combined process coupled further with full-hydrogenation process.
