Important news!

On the morning of June 26, 2022, two sets of 10 million-ton atmospheric and vacuum distillation units of Guangdong Petrochemical Refining and Chemical Integration Project were handed over.
In addition, the world's largest single set of aromatics combined unit substation, cabinet room, 6# oily sewage pretreatment Processing station, a total of 5 main units are handed over on the same day
.
This world-class refining and chemical integration project leading device has entered the stage of preparation for start-up
.

The Guangdong Petrochemical Project has a construction scale of 20 million tons/year of oil refining + 2.
6 million tons/year of aromatics + 1.
2 million tons/year of ethylene.
It is the only refining and chemical project built by PetroChina in Guangdong, and it is also the largest one-time investment project
.
It is of great significance to improve the balance and coordination of regional development
.
The member companies of CNPC have undertaken the construction of 155 main units of the project.
As of June 26, 82 projects have been handed over to China
.
Up to now, the total construction progress of Guangdong Petrochemical Project has exceeded 98%
.

Atmospheric and vacuum distillation is the leading device of the refinery, which determines the processing capacity and competitiveness of the refinery
.
The first joint and second joint 10 million tons/year atmospheric and vacuum distillation units of CCCC were contracted by China Petroleum Engineering Construction Co.
, Ltd.
EPC
.
This is also the largest atmospheric and vacuum distillation unit for unconventional crude oil with ultra-heavy and inferior quality in China
.

【Million-ton atmospheric and vacuum device】

Two sets of 10 million-ton atmospheric and vacuum distillation units were contracted by CPECC, and were constructed by the first construction company and the seventh construction company respectively.
One of the combined atmospheric and vacuum distillation units was managed by the project management company Jilin Mengxi, and the second one was managed by Jilin Mengxi.
The combined atmospheric and vacuum distillation unit is supervised by the project management company Beijing Xingyou
.
The two units are also the largest atmospheric and vacuum distillation units for unconventional crude oil with overweight and inferior quality in China
.

Since the start of construction in March 2020, the general contractors, construction units, and supervision units have strictly implemented the requirements of "not slack in epidemic prevention, and not slowing down construction", seized key paths, processes, and nodes, and made every effort to promote the daily guarantee of the week and the week of the month.
Project construction
.

The two sets of 10 million tons of atmospheric and vacuum distillation units have the characteristics of large equipment specifications and high pipeline complexity
.
By vigorously promoting factory prefabrication and modular installation, the on-site workload is greatly reduced, the work efficiency is improved, and the risk of working at heights is reduced
.
The factory prefabrication depth of the pipeline reaches more than 50%, and 100% of the tower and container equipment arrives as a whole
.

The Guangdong Petrochemical Project is located in the Great South China Sea, Guangdong, and is built near the sea
.
In response to the problem of high groundwater level, the civil construction of the whole plant adopts the method of "well point precipitation"; in response to the problems of rainy weather in the south and many high-altitude operations, measures such as on-site construction of rain-proof shelters and high-altitude operation vehicles are adopted to ensure construction.
Safety, quality and progress
.

Two sets of 10 million tons/year atmospheric and vacuum distillation units are designed with green, intelligent and efficient as the design principles.
While making full use of ultra-heavy and inferior crude oil resources to improve the processing depth, it minimizes pollutant emissions and achieves clean production
.
At the same time, it can fully recycle the waste heat of the device, and achieve the purpose of reducing energy consumption by combining with the heat of the downstream device
.

The Guangdong Petrochemical Refining and Chemical Integration Project is an important measure for PetroChina to implement the national energy security strategy, utilize "two resources" and "two markets", establish an integrated international cooperation model for upstream, midstream and downstream, and build a comprehensive international energy and oil company.
The company's refining and chemical business transformation and upgrading, strategic projects to promote high-quality development, and key projects to promote economic development in eastern Guangdong
.

At present, the overhead torch system, as well as gasoline product tank farm, refined oil tank farm substation I, refined oil tank farm substation II, 8# oily sewage pretreatment station, 5# foam station in oil refining area, and 6# foam station in oil refining area A total of 7 main units have been handed in at the end of May
.

Overhead Flare System:

The overhead flare system is a plant-wide safety facility used to treat combustible exhaust gas from various devices and tank farms
.
During the installation of the torch system, the First Construction Company adopted the "factory prefabrication and modular installation" plan to complete the installation of two sets of torch towers in 75 days; the "multi-machine lifting and sliding method" was adopted to complete the torch track installation in 22 days Mission: Combining and innovating the torch construction method and the double-facade tower type torch construction method, and successfully completed 9 sets of torch tube installation tasks through the "crane lifting method", creating the "Asian torch installation" with the largest diameter, the highest height and the largest number of torches.
"New record
.

Gasoline finished product tank farm:

The gasoline product tank area consists of 10 30,000-cubic-meter floating-roof storage tanks and a pump area.
It is used to store the blended and qualified gasoline and transport it to the outside.
It is one of the core devices of the refined oil product tank area
.
During the construction process, the first construction company applied automatic welding technology in a large area, which effectively shortened the construction period and ensured the installation quality of the storage tank
.
In the floating plate installation in the tank group, the construction method of modular floating plate installation was created, and the installation task was completed quickly and efficiently
.

Substation I/II of Refinery Tank Farm:

The refined oil tank farm substation I mainly includes 4 sets of 10kV oil-immersed transformers, 3 sets of 10kV dry-type transformers, 28 10kV switchgears, and 62 low-voltage switchgears
.
Substation II mainly includes 2 sets of 10kV oil-immersed transformers and 31 low-voltage switch cabinets
.
The transfer of the two substations has laid a solid foundation for the test run of the surrounding tank groups
.

8# Oily Sewage Pretreatment Station:

8# Oily Sewage Pretreatment Station is composed of 522.
5 cubic meters of oily sewage collection tank, supporting 4 lift pumps and waste gas treatment equipment.
It is mainly used to receive the oily sewage discharged from the gasoline component tank group and the gasoline product tank area
.

5#, 6# factory foam station:

The 5# and 6# foam stations are respectively composed of a foam liquid storage tank and two foam pumps, which are used to eliminate fire hazards in the gasoline product tank group, chemical raw material tank group, jet fuel product tank group and other units in the radiation area.
