Operation Analysis of 1.6 Million Tons/Year Waxoil Hydrocracking Unit
This paper introduces the main technical characteristics and catalyst loading of the 1.6 million tons/year paraffin hydrocracking unit of a company.The main operating parameters,raw materials and product properties,material balance and energy consumption of the unit are analyzed in detail.The operation data show that hydrofining catalyst F-6 and hydrocracking catalyst F-5 and F-8 have good activity and stability,and the product distribution and quality can be controlled by adjusting the reaction temperature.The fractionation system and absorption stabilization system can selectively cut each side line product according to the production demand,and all products meet the production requirements.The device runs stably at 110%load,and the equipment such as circulating hydrogen compressor,supplementary hydrogen compressor,reaction feed pump and heating furnace all run stably without bottleneck problem.The comprehensive energy consumption of the device is 29.6 kgeo·t-1,which is better than the designed energy consumption.
