Five main units including 10 million ton atmospheric and vacuum unit were delivered on the same day

On the morning of June 26, the South China Sea was surrounded by blue skies and bright sunshine.
The Guangdong Petrochemical Refining and Chemical Integration Project delivered another good news: the "leading" devices in the project's refining area - two sets of 10 million-ton atmospheric and vacuum distillation units, The world's largest single set of aromatic hydrocarbon combined plant substation, cabinet room, 6# oily sewage pretreatment station, a total of 5 main units were handed over on the same day
.

The construction scale of Guangdong Petrochemical Project is 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 constructed 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
.

【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
.

Zhou Jian, general manager of Guangdong Petrochemical Company, Yang Shibang, deputy general manager of CNPC Engineering and other leaders attended the ceremony
.
In his speech, Zhou Jian expressed his gratitude to all the employees who participated in the construction
.
He said, "All parties conscientiously implement Guangdong Petrochemical's decision-making and deployment, keep an eye on the node goals, go all out to overcome unfavorable factors such as epidemic prevention and control, thunderstorm weather, and extreme heat, organize construction scientifically, strictly control construction quality, strictly abide by project progress, and use actual conditions.
