PetroChina largest naphtha hydrogenation unit under construction was successfully put into trial operation!

On November 28, the 3 million tons/year naphtha hydrogenation unit of the Guangdong Petrochemical Refining and Chemical Integration Project which located in Jieyang City, Guangdong Province produced qualified refined naphtha.It marks the successful commissioning of the largest naphtha hydrogenation unit under construction in PetroChina.

PetroChina introduced that the 3 million tons/year naphtha hydrogenation unit of the refining and chemical integration project adopted UOP's naphtha hydrogenation process technology and HYT-1119 catalyst.Using straight-run naphtha and hydrotreated coker naphtha as raw materials from the upstream atmospheric and vacuum unit, it provides qualified raw materials for the downstream continuous reforming unit through hydrogenation and fractionation.

In the early stage of the construction of the device, Guangdong Petrochemical Company communicated with the design and procurement units many times to continuously optimize the design plan.3 cylindrical furnaces with a total weight of up to 3200 tons adopt the overall delivery and installation mode.It deeply demonstrated the advantages of fine modular control, high efficiency, good quality and short construction period, and created a precedent for the overall modular delivery of the heating furnace of the PetroChina system. The design thermal efficiency of the heating furnace of the device reached 94%.It is reported that this year, on 21th. May , the 3 million tons/year naphtha hydrogenation unit held a handover ceremony.It marks that PetroChina's largest naphtha hydrogenation unit under construction has entered the production preparation stage 25 days ahead of schedule.Became the first oil refining production unit of handover in the Guangdong petrochemical project.
