PetroChina's largest naphtha hydrogenation plant under construction produces qualified products

At 14:30 on November 28, after continuous operations and overcoming difficulties, the 3 million tons/year naphtha hydrogenation unit of Guangdong Petrochemical Refining and Chemical Integration Project produced qualified refined naphtha, marking the successful
commissioning of the largest naphtha hydrogenation unit under construction by PetroChina.

The 3 million tons/year naphtha hydrogenation unit of Guangdong Petrochemical Refining and Chemical Integration Project adopts UOP's naphtha hydrogenation process technology and HYT-1119 The catalyst uses the straight distilled naphtha and hydrotreated coke naphtha of the upstream atmospheric pressure reducing device as raw materials, and provides qualified raw materials
for the downstream continuous reforming unit through hydrogenation and fractionation.

In the early stage of the construction of the plant, Guangdong Petrochemical Company communicated with design and procurement many times to continuously optimize the design plan
.
The three drum furnaces with a total weight of up to 3,200 tons adopt the overall delivery and installation mode, which deeply demonstrates the advantages of fine modular control, high efficiency, good quality and short construction period, creating a precedent for the overall modular delivery of the heating furnace of PetroChina system, and the thermal efficiency of the device heating furnace design reaches 94%.

。 Since the start of construction on June 18, 2020, Guangdong Petrochemical Company has given full play to the advantages of the integrated operation of the joint management team, worked with general contracting, supervision and construction to overcome many difficulties such as complex process routes, large engineering operations, and the impact of the epidemic, established a project promotion meeting mechanism, strictly assessed and supervised, and strictly controlled key links to ensure that the project progress and node goals were always under control
。 On May 21, 2022, the 3 million tons/year naphtha hydrogenation unit held a CCCC ceremony, marking that PetroChina's largest naphtha hydrogenation unit under construction entered the preparation stage of production 25 days ahead of schedule, becoming the first set of CCCC's refining production unit
for the Guangdong Petrochemical Project.

In the stage of equipment start-up and commissioning preparation, Guangdong Petrochemical Company strictly implements the principle of "single-machine test should be early, purging air tightness should be strict, linkage test should be complete, feeding test should be stable, and economic benefits should be good" put forward by Dai Houliang, chairman of China National Petroleum Corporation, combined with the overall deployment of test tasks, clarify the target tasks, refine work measures, compact work responsibilities, and make every effort to ensure the seamless
connection of all links 。 At the same time, in view of the problems that occurred in the test run, the attack team headed by the main person in charge of the company's four refining and production departments discussed and comprehensively analyzed one by one, determined the emergency adjustment plan in a timely manner, and seriously rectified the problems such as three inspections and four determinations, PSSR problem sales items
, etc.

During the development of various work, the party committee of the four departments of oil refining and production of the company gave full play to the role of "taking direction, managing the overall situation, and promoting implementation", and successively established a number of party member commando teams and youth commando teams to help key targets in many tough battles such as three inspections and four determinations, and started production, which effectively guaranteed the smooth completion of the test task of the device and laid a solid foundation
for the successful commissioning of the device.
