摘　　要：福建福海创石油化工有限公司5.0 Mt/a凝析油加氢装置通过全馏分加氢脱硫、脱氮和物理分离的方法连续稳定地生产出精制石脑油和低硫柴油产品。长周期工业应用结果表明:采用催化剂HR-608,通过对不同凝析油进行试验,全馏分凝析油加氢后可以生产符合重整装置进料要求的精制石脑油和低硫国Ⅵ柴油组分,精制石脑油能保证重整装置稳定运行。由此可见,通过对凝析油加氢装置生产工艺条件的优化,可以实现有效降低凝析油中的硫、氮含量,生产出硫质量分数小于3.0μg/g的精制凝析油产品,取得预期的技术效果。凝析油加氢过程放热量低,燃料气和高压蒸汽消耗在装置总能耗中占比较高,通过优化加热炉对流段取热量、排烟温度、加热炉氧含量及汽提塔塔底温度和回流量等参数,达到提高加热炉效率和降低高压蒸汽消耗的目的,从而降低装置能耗。The 5.0 Mt/a condensate hydrotreating unit in Fujian Fuhaichuang Petrochemical Co.,Ltd.is continuously and stably producing low-sulfur naphtha and low-sulfur diesel products by means of full distillate hydrodesulfurization,denitrification and physical separation.The results of long-term industrial application show that using the catalyst HR-608,through the production test of different kinds of condensate oil,the refined naphtha and the low sulfur diesel can be produced by hydrogenation of the whole fraction condensate oil,and the refined naphtha can be beneficial to the stable operation of the reforming unit.It could be seen that the content of sulfur and nitrogen in the condensate could be effectively reduced by optimizing the process conditions of the condensate hydrotreating unit,the refined condensate products with sulfur content less than 3.0μg/g could be produced,and the desired technical results were achieved.The heat release of the condensate hydrogenation process is low,and the energy consumption of fuel gas and high-pressure steam are high in the total energy consumption of the unit.By optimizing the parameters such as heat capacity,flue gas temperature,oxygen content of heating furnace,temperature of stripper bottom and reflux rate in convection section of heating furnace,the efficiency of heating furnace is improved and the consumption of high-pressure steam is reduced,thus the energy consumption of the unit is reduced.
