The world's largest single set of aromatics plant and CNPC's largest continuous reformer

　　On July 30, the handover ceremony of the 2.
6 million t/a aromatics complex and two sets of 3 million t/a continuous reforming units of the Guangdong Petrochemical Refining and Chemical Integration Project (referred to as Guangdong Petrochemical Project) were held at the plant construction site respectively.

.

　　The 2.
6 million tons/year aromatics complex is currently the largest aromatics unit in the world with the largest single production capacity, and one of the core units of the Guangdong Petrochemical Project.
The dependence of aromatic hydrocarbons improves the self-protection ability of raw materials
.

　　The aromatics complex delivered this time was contracted by Kunlun Engineering Company EPC, and the No.
7 Construction Company of Engineering Construction Company, China Aneng Group First Engineering Bureau Co.
, Ltd.
and other units were responsible for the construction
.
The aromatic hydrocarbon complex has 7 thousand-ton equipment, 4,330 cast-in-place piles, 42,000 tons of concrete pouring, 21,000 tons of steel structure installation, and a welding equivalent of 810,000 inches of process pipes.
It is a veritable "aromatic giant".

.

　　Since the start of construction in April 2020, the participating units such as Guangdong Petrochemical Company, Kunlun Engineering Company, and Engineering Construction Company have carefully planned, strictly deployed, and organized the construction scientifically
.
The aromatics complex was successfully handed over and achieved 12.
8 million safe production man-hours, marking that the Guangdong Petrochemical Project is one step closer to the start of production
.

　　Two sets of 3 million tons/year continuous reforming units are an important part of the five combined units of the Guangdong Petrochemical Project
.
The five combined units are located in the refining area of ​​the Guangdong Petrochemical Project and are contracted by Huanqiu Engineering Company.
They also include a set of 3 million tons/year naphtha hydrogenation unit and a set of 420,000 standard cubic meters/hour hydrogen recovery unit
.
The two continuous reforming units and the naphtha hydrogenation unit are the largest units of their kind under construction by PetroChina
.

　　The two sets of continuous reforming units have a compact layout, the steel structure frame is up to 101 meters, and the oil transfer lines of special materials intersect vertically and horizontally.
There are many high-altitude operations and large-scale construction machinery, which makes the construction difficult
.
During the construction process, Guangdong Petrochemical Company, Huanqiu Engineering Company, the Sixth Construction Company of Engineering Construction Company, Jilin Mengxi Company and other participating units analyzed the construction key points and difficulties according to the overall plan, and compiled the process pipeline installation, heating furnace construction and countermeasures.
Reframe construction is a special construction plan for key lines
.

　　The 8 square box-type heating furnaces and 24-stage convection section modules of the continuous reforming unit are all manufactured, transported and installed in a modular manner; the reverse frame is assembled into pieces on the ground, and then connected into a frame and a whole frame.
Construction by hoisting
.
This "micro-module" hoisting method effectively reduces the frequency of use of cranes, pallet trucks and other equipment, improves the speed of framing, reduces labor and mechanical costs, and reduces high-altitude operations and construction risks
.

　　The two sets of continuous reforming units have been handed over, marking that the five combined units of the Guangdong Petrochemical Project have achieved full handover and entered the stage of commissioning
.
After the five combined units are put into operation, on the one hand, they are responsible for receiving the hydrogen-rich materials in the whole plant, and after purification, they are used by the whole plant; The reformed gasoline containing aromatic hydrocarbons further increases the added value of the products of the whole plant
