It is understood that the total investment of the device project is 192.80 million yuan. It uses the third generation of catalyst dry gas to produce ethylbenzene technology from the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences and Fushun No. 2 Plant. Construction began in August 2005, and high levels were achieved in November 2006. It is expected that construction will begin in October 2007.
As early as April of this year, Daqing Refining & Chemical began to prepare for catalyst loading, established a lead group for catalyst packing, specially organized catalyst loading, and communicated with experts from Dalian Institute of Materials and Fushun Design Institute. Refined the filling scheme. During the process of catalyst loading, Daqing Refining and Chemicals specially designated a person to carry out the metering and proportioning of the catalysts, and to accurately record the loading amount of each bed of catalyst and ceramic balls and the loading of the bed, and to adopt a catalyst-by-segment filling method. Stage by paragraph, to prevent different types of agents, different parts of the catalyst confusion.
The commissioning of this set of equipment will make full use of the valuable ethylene resources in the Daqing refining and catalytic cracking dry gas, which will play a decisive role in effectively balancing the pressure of the fuel gas pipeline network.
Daqing refinery dry gas production of ethylbenzene equipment complete catalyst loading
On May 19, the largest 100,000 tons/year dry gas ethylbenzene plant in Daqing Refining & Chemical Company has completed the catalyst loading of three reactors. At present, the preparation work for the start-up of the plant is progressing smoothly.
