Huanqiu Company's "Six Modernizations" Construction Breakthrough Creates a New Situation in the Field of Engineering Construction

On September 5, Guangdong Petrochemical’s 1.
2 million tons/year ethylene plant pyrolysis gasoline hydrogenation process unit PAU-03, which was contracted by Huanqiu Company’s EPC, was installed as a whole.
This is the implementation of Huanqiu Company’s "Six Chemicals" construction requirements.
The milestone project achievement is the first time that Huanqiu Company has piloted a full-process, full-professional, and fully independent modular construction project in the process unit of a large petrochemical plant, marking Huanqiu's refining and chemical engineering The construction field has opened up the whole process of "six modernizations" construction, which fully embodies the EPC capabilities of Huanqiu Company and the advantages of integrated project management
.

The module is a steel frame with a length of 42 meters, a width of 9 meters, and a height of 13 meters.
It is divided into 3 layers and contains 13 static equipment, 6000-inch pipelines and supporting electrical instruments.
The overall weight is 675 tons
.

Its main task is to reprocess the by-product "pyrolysis gasoline" of the ethylene plant, to hydrogenate unsaturated olefins in the pyrolysis gasoline, and to hydrocrack and purify hydrocarbon compounds containing other elements

Standardized design leading traction

Standardized design is the foundation and leader of the "six modernizations" construction
.

In the module design stage, Huanqiu Beijing has always adhered to standardized design, high-quality, high-efficiency and rapid advancement of design work, which not only achieved efficiency improvement in the design process, but also had a significant effect on the source optimization of subsequent processes

Although modular construction is of great benefit and is a new trend in engineering construction, it is not easy to build a small "device"
.

In the design stage, it is necessary to consider both the "device" itself and how to divide each module unit: each module design satisfies the transportation conditions, and the connection between the modules should also be minimized

Obvious advantages of modular construction

Obvious advantages of modular construction

Modular construction has the advantages of short construction period, better construction efficiency and quality controllability, and higher construction safety
.

　　The gasoline hydrogenation unit of the ethylene plant is divided into 4 process modules, 3 public engineering modules and 5 skid blocks according to process functions.
They are gasoline hydrogenation reaction module, first stage stabilizer/depentanizer heat exchange module, and hydrogenation reaction.
Heat exchanger module, second-stage stripper/de-octane tower heat exchange module, 2 pipe gallery modules, 1 pipe gallery truss module, 1 compressor skid and 4 tower skids
.

The structure is compact, covering a full range of specialties, the structure and equipment are high, large, and heavy, and the construction process is complex and the amount of work is large

　　Huanqiu Beijing Company integrates standardized design, procurement innovation, and uses factory prefabrication to process and build in Huanqiu Six Construction Company’s equipment manufacturing plant.
The construction was officially started on May 25, and the overall shipment was shipped on August 24.
The construction task was successfully completed in 88 days.
, Which shortens the construction period by 1 month compared with the traditional construction method
.

Compared with conventional on-site installation, the modular construction method greatly reduces the safety risks caused by on-site cross-operations, reduces the impact of operations in other areas, realizes the simultaneous operation of civil construction and installation, greatly improves work efficiency, and guarantees Improve the quality of the project

　　Party building leads the cohesion

　　The project joint management team established by Huanqiu Beijing Company and Huanqiu Six Construction Company, based on the new development stage, implements the new development concept, adapts to the new development pattern, and steadily promotes the organic integration of the "three basics" construction and the "three basics" work of grassroots party building, and gives full play to it The role of the party building in "directing, managing the overall situation, and ensuring implementation", comprehensively consolidate the basic organization, build a strong fighting fortress, and firmly establish the "global one flag" idea, taking the implementation of the "six modernization" work requirements of the group company as the starting point and giving full play to it EPC project integrated management advantages, from module design, procurement, prefabrication, transportation to installation, carefully control each process, carefully deploy each link, achieve the ultimate management work, continuously optimize the module design, accelerate the procurement progress, and make every effort Ensure the efficient construction of modules

　　The overall modular construction of gasoline hydrogenation modules is a new breakthrough in the engineering construction model and the fruit of Huanqiu's comprehensive promotion of the "six modernizations" construction concept, creating a new situation in the company's engineering construction
