The total investment is 125 billion yuan!

At 13:19 on June 21, the first air separation unit of Shaanxi Coal Group Yulin Chemical Company Air Separation Thermal Power Project Department was successfully commissioned, producing qualified oxygen and nitrogen products, marking the successful completion of another milestone for the company
.

In order to ensure the successful commissioning of the first air separation plant and the one-time production of qualified products, the company attaches great importance to and plans ahead, organizes relevant departments to hold several special meetings and conducts multiple inspections, coordinate and solve problems of all parties, and strictly control safety and quality.

.
At the same time, the project department carefully sorted out the key points and risk points in the commissioning process, strictly wrote the commissioning and isolation plan, deployed various tasks according to the commissioning progress, and successfully completed the "three inspections and four determinations" final sales, steam turbine overrun, Preliminary work such as unit linkage test, purging air tightness, cold box bare cooling, pearl sand filling, etc.
, has laid a solid foundation for the successful commissioning of the first air separation unit
.

At present, the air separation unit is running smoothly, and all indicators of oxygen and nitrogen products meet the design requirements
.
The project department will take this opportunity to make persistent efforts to promote the follow-up work in an all-round way with a solid work style, and strive to successfully complete the company's goals and tasks
.

It is reported that the project is equipped with 3 sets of 100,000 Nm³/h air separation units, which are mainly responsible for providing instrument air, factory air, nitrogen and oxygen of various specifications and pressure levels for the production units
.
The device has advanced design parameters and process technology, and has the characteristics of reliable operation, convenient operation, good safety, and easy control.
It adopts low-temperature air separation technology widely used in industry, including air compressor unit system, pre-cooling system, molecular sieve system, replacement Thermal system, booster turboexpander system, rectification system

Shaanxi Coal Group Yulin Chemical Co.
, Ltd.
is the largest coal chemical project under construction in the world.
The project covers a total area of ​​about 13 square kilometers.
The planned total investment is about 125 billion yuan, and the annual conversion of coal is about 2,400 yuan.
10,000 tons, including a total of 27 process units and supporting public works, mainly including 15 million tons of coal medium and low temperature pyrolysis, 5.
6 million tons of methanol, 1.
8 million tons of ethylene glycol, 2 million tons of olefins and downstream intermediate raw materials.

.

Among them, the 1.
8 million tons/year ethylene glycol project in the first phase of the project covers an area of ​​about 4.
4 million square meters, and the total investment of the project is estimated to be about 26.
5 billion yuan.
It is also the largest coal-to-ethylene glycol plant under construction in the world; one The second stage is the construction of 5.
6 million tons/year methanol, 2 million tons/year olefins and deep processing projects, which are planned to be completed by the end of 2023
.

The second phase of the project takes coal pyrolysis as the leader and is also divided into two stages.
The first stage is a 1.
2 million ton/year pulverized coal pyrolysis and a 500,000 ton/year coal tar deep processing industrialization demonstration device; the second stage will enlarge the scale of pyrolysis.
To 15 million tons, and to extend the coal tar industry chain to produce aromatic hydrocarbons and aromatic olefin-combined downstream products, it is planned to start construction in 2022, and complete all construction content by the end of 2025
