In September 2020, in Yanchang China Coal Yulin Energy and Chemical Company (Yuneng Chemical), the construction site was filled and completed.
All the construction personnel were sweating like rain to seize the golden period of construction, and they were making every effort to prepare for the commissioning after the project was handed over.
Resolutely Keeping the bottom line of "commissioning is not in winter", we will make every effort to promote the commissioning of the project to ensure the smooth realization of the goal of "commissioning and commissioning at the end of October"
.
Using coal and oilfield gas as raw materials, with the help of the mature technical experience obtained from the first phase of Yuneng Chemical's start-up project, and on the basis of making full use of existing public facilities, the total investment of the project is about 14.
413 billion yuan, and the construction of 1.
8 million tons/year methanol, 600,000 tons/year DMTO, 300,000 tons/year LDPE/EVA integrated unit and 300,000 tons/year PP unit
.
DMTO plant has fully started production preparations
DMTO plant has fully started production preparationsIt was learned on September 14, 2020 that according to the introduction of Hao Yong, the on-site director of the DMTO plant olefin project department of the DMTO plant, "the main project of the DMTO plant construction project has been completed, and the equipment installation, process piping, site hardening, and anti-corrosion insulation have been fully completed.
, the finishing work is in progress, and the project acceptance and trial operation are under intense preparation.
In the next step, we will make every effort to do the key work of the single-machine test run of the large-scale unit, the drying and lining of the two devices, and the air-tightness and drying of the separation unit.
The foundation for driving success is laid
.
Up to now, the DMTO plant has fully started production preparations, and the process pipeline purging and blasting, instrument debugging, steam pipeline purging and targeting, compressor oil transportation, water combined transportation of quench water washing unit, and two-device oven are being carried out in an orderly manner
.
The first large-scale unit of LDPE/EVA plant was successfully commissioned
The first large-scale unit of LDPE/EVA plant was successfully commissionedOn September 7th, the first large-scale nitrogen compressor of the LDPE/EVA plant started the test run.
After a day of hard work, the test run was successful at 19:30 on the same day, reaching the normal working pressure of 28.
27MPa
.
It is understood that before the introduction of nitrogen for the preparation of the test run, the technical management personnel of the LDPE/EVA plant made technical disclosures to the employees, and carried out PSSR, commissioning training, analysis of work points, air tightness inspection, and safety hazard investigation
.
The single test of the 3# steam turbine of the air separation unit was successful
The single test of the 3# steam turbine of the air separation unit was successfulOn September 8, the single test of the 3# steam turbine of the air separation plant of the filling and filling project was successfully completed, laying a good foundation for the subsequent unit joint test and cold box test
.
The person in charge of the air separation plant said that in order to ensure the success of the single test of the steam turbine, all the staff overcame many difficulties, kept an eye on the nodes, set the target, and actively organized and completed a series of work such as lubricating oil circulation, replacement, steam line purging, instrument debugging, etc.
Stand-alone test conditions

PP3 device fully promotes the project test run
PP3 device fully promotes the project test runIt was learned on September 10 that in order to actively promote the project commissioning work, fill in and complete the construction of the PP3 plant of the project, all the participants in the construction of the PP3 plant worked together and worked closely together, strictly grasped the safety and quality management, implemented various safety production measures, and strictly followed the company's "project commissioning does not work.
" The overall goal of "Winter" to ensure efficient completion and production
.
At present, the completion rate of the pressure test package is 100%, the completion rate of the three-inspection and four-determination projects is 68.
73%, the completion rate of the test motor is 66.
50%, the completion rate of the single-machine test operation is 54.
11%, the completion rate of the combined test operation of the equipment is 54.
11%, and the instrument circuit test is completed.
The rate was 56.
89%, and the completion rate of the system purging package was 80.
30%
.
In order not to delay the progress of the project, the installation personnel took three shifts to take over the work to ensure the safe and efficient progress of the project

——Brief introduction and project background of Yuneng Chemical CompanyShaanxi Yanchang China Coal Yulin Energy Chemical Co.
, Ltd.
is a large-scale coal, gas and oil comprehensive utilization chemical enterprise jointly established by Shaanxi Yanchang Petroleum Group and China Coal Energy through capital increase and share expansion.
It was established on May 24, 2010 with a registered capital of 10 billion Yuan
.
The company's startup project was completed and put into production in July 2014, and in August 2015, it was transferred from the construction period to the production and operation period
.
The company is located 10 kilometers northeast of Jingbian County, with a planned resource control area of about 40 square kilometers, of which the start-up project area is about 7 square kilometers
.
In accordance with the requirements of the National "Petrochemical Industry Adjustment and Revitalization Plan" and "Ordos Basin Energy Development and Utilization Overall Plan", the start-up project will build 1.
8 million tons/year methanol, 1.
5 million tons/year residual catalytic thermal cracking (DCC), 600,000 tons/year /year DMTO, 2 X 300,000 tons/year polyethylene (PE), 2 X 300,000 tons/year polypropylene (PP), 90,000 tons/year MTBE, etc.
8 sets of main production units and supporting public works
.
The estimated investment in the facility is 27 billion yuan, and 14 domestic and foreign patented technologies are adopted
.
In November 2009, the project was identified as a "clean coal technology demonstration and promotion project" by the National Development and Reform Commission and the United Nations and other relevant organizations
.
The project is a key project of the energy and chemical base in northern Shaanxi, and it is also the first demonstration project for the comprehensive transformation of coal, gas and oil in Yanchang Petroleum to realize upstream and downstream polygeneration
.
The first phase of the comprehensive utilization of resources in Jingbian Energy and Chemical Park is the core support project of the high-end energy and chemical base in northern Shaanxi
