The world's largest single coal-to-liquid project reaches production for the first time

On December 19, 2021, Ningmei Coal-to-Liquid Branch of National Energy Group produced 4.
05 million tons of petrochemicals this year.
This single largest coal-to-liquid project in the world has reached the designed production capacity for the first time since it was completed and put into operation
.

The project started construction on September 28, 2013 in Ningdong Energy and Chemical Base, which is the largest one-time investment and construction chemical project in the world's petrochemical and coal-to-liquid chemical industry
.

On December 28, 2016, Line A of the project was completed and put into production and produced qualified oil products, marking that the National Energy Group has realized the industrial application of indirect liquefaction of one million tons of coal-to-liquids after the direct liquefaction of one-million-ton coal-to-liquids.
Make China one of the few countries in the world that has mastered both direct and indirect large-scale coal-to-liquid technologies; at the end of 2017, the 4 million tons/year indirect coal liquefaction complete set of technological innovation development and industrialization projects were all put into operation; the overall load in 2019 Up to 90%, and the pass rate of process indicators is over 99%; in 2020, the first full-depth overhaul will be carried out after the completion of the plant, to eliminate a series of bottleneck problems affecting the operation of the plant, to achieve full-load operation of two lines at one time, and to continuously refresh daily and monthly production Record; in 2021, the daily output of petrochemicals will reach a maximum of 12,100 tons, and the monthly output will reach a maximum of 372,000 tons
.

In the past 5 years, Ningmei Co.
, Ltd.
of the National Energy Group has carried out 4 rounds of 559 key technological transformations, and continued to overcome and solve the major core technologies that affect the safe, stable and clean operation.
The second innovation has overcome many problems such as unreasonable process design, cumbersome interlocking control, and high content of crude gas ash; the project has invested a total of 7 billion yuan in environmental protection, effectively solving the problem of air, sewage and solid waste discharge
.

The development and practice of large-scale indirect coal liquefaction system integration and clean operation technology have achieved safe, stable and clean operation of the device.
The project technology is generally at the international leading level, and was recently awarded the first prize of the 2020 National Science and Technology Progress Award
