On May 9th, the core device of Hengli Petrochemical (Dalian) 20 million tons/year integrated refining and chemical project undertaken by Nanjing Engineering Company-2# aromatics combined device was successfully put into operation at one time, producing qualified PX finished products with a purity of 99.
72%.
The company successfully completed the construction of the 2.
25 million tons/year aromatics combined plant of Hengli Petrochemical (Dalian)
.
So far, the two aromatics plants of the project have been put into full production, with an overall processing capacity of 4.
5 million tons per year, which is far ahead in the domestic refining and chemical industry
.
????? Hengli Petrochemical (Dalian) 20 million tons / year refining and chemical integration project, as the first large-scale private refining and chemical project approved by the state, was listed by the National Development and Reform Commission as a "three-year rolling focus for promoting the revitalization of the old industrial base in the Northeast.
The “Promotion Project” is a petroleum refining and chemical project with the largest one-time construction scale, the most complex technical process, the highest degree of business integration, and the most complete industrial supporting facilities in China.
"A world-class petrochemical industrial park
.
???? The combined plant undertaken by Nanjing Engineering Company is currently the world's largest single-body aromatics plant, mainly including 2# 2.
25 million tons/year PX device, 2# 1.
5 million tons/year aromatic extraction device, 2 # 3.
3 million tons/year disproportionation unit
.
The main physical construction volume includes: 45,445 cubic meters of concrete, 19,600 square meters of buildings; 20,226 tons of steel structure, 191 sets of moving equipment, 443 sets of static equipment, 26.
65 kilometers of water supply and drainage pipes (63270 inches of standard pipe welds), and 260 process pipes Kilometers (1139108 inches of pipe standard welds); 803 sets of electrical equipment, 4637 sets of instrumentation equipment, and 583 kilometers of cable laying
.
???? Since the installation of the steel structure of the Dalian Aromatics Project started at the end of December 2017, all the construction personnel have worked together, which lasted only 15 months, and completed the construction tasks in a safe, quality and quantity manner
.
In the process of project construction, various difficulties have been experienced.
In the case of late arrival of equipment and materials, the project department adheres to the concept of "demanding time from key lines and demanding resources from non-critical lines", with xylene towers and adsorption towers as key lines.
With 6 main corridors, 2 compressor workshops, and 1 generator workshop as the secondary key line, the overall network plan was compiled
.
During the construction process, focus on tracking the progress of drawings and materials, and adjust the planning and progress in time based on the actual situation on the site
.
Strictly plan and operate around the construction goals, carefully compile construction organization design and construction technical plans, strengthen dynamic control, strengthen construction coordination, and solve construction contradictions in a timely manner
.
???? Aiming at the key points of the phased construction, optimize the allocation of human resources, concentrate on highlighting the key points, reasonably extend the operation time, and require employees to complete the tasks of the day
.
With the changes in the drawing and material arrival situation, the project department analyzed the reasons that hindered the progress, revised the plan in time, and tried its best to eliminate the unfavorable factors caused by the lag of the drawings
.
At the same time, the work of the production and operation center is organically combined with the evaluation of the construction team, and the criteria for the pioneering and excellent evaluation and the daily work management evaluation are integrated, which effectively promotes construction production and ensures the effective progress of project construction
.
???? The oil is supplied from the xylene unit, and the project department starts to cooperate with the workshop to ensure transportation
.
It only took 20 days for the whole device to get through the whole process and produce qualified PX products at full load, which was the fastest driving record for similar devices
.
Next, the project department will cooperate with the workshop to ensure the safe, stable and high-quality operation of the equipment, and draw a successful conclusion to the project
