炼厂焦化装置含硫废水除焦粉中试研究

Pilot Test on Removing Coke from Sulphide Wastewater in the Coker

絮凝法水处理技术和借助设计的反应沉降分离装置中试试验表明,该方法能显著除去含硫废水中的焦粉,焦粉含量从114.7mg/L降低到14.4mg/L,焦粉的除去率达到87.4%。延迟焦化具有投资少、操作费用低、转化深度高等优点,已发展成为渣油轻质化最主要的加工方法之一。因此,目前我国轻油产品尤其是在柴汽比供需矛盾突出的情况下,延迟焦化是解决这一矛盾的较理想手段之一。

Technology of flocculence water treatment and the designed device of reaction, sedimentation, and separate pilot scale modified that it can obviously eliminate coke in sulphide wastewater, coke content reduced form 114.7 mg/L to 14.4 mg/L, coke removal rate can reach to 87.4%. Delayed coking has the characteristics of low investment, low operating costs, and high transforming depth, and it has developed into the main processing way of residual oil conversion to light fraction. So nowadays, under the situation that imbalance between supply and demand of white oil products, especially that ration of diesel fuel and gas, delayed coking is the ideal way to solve the conflict.
