摘要
在当前柴油产能过剩柴油消费市场需求日渐饱和的形势下,镇海炼化对现有两套3.0 Mt/a柴油加氢装置进行裂化改质升级改造。通过装填部分裂化剂及其他一系列配套改造措施,使改造后的石脑油收率分别提高3%~10%,整体降低公司柴汽比0.13%,提高了炼厂经济效益,为同类装置提供了改造方向及经验总结。
In the current situation of excess diesel capacity and increasingly saturated market demand for diesel,SINOPEC Zhenhai Refining and Chemical Company modified its two existing 3.0 Mt/a diesel hydrogenation units for cracking upgrading.By loading some cracking catalysts and taking a series of supporting modification measures,the naphtha yield after modification is increased by 3%to 10%respectively,and the diesel-gasoline ratio of the company is reduced by 0.13%,which improves the economic benefits of the refinery and provides direction and experience for modification of similar units.
