What are the advantages of the new process technology developed by the Chinese Academy of Sciences in Puyang, Henan for the first domestic ethylene-based MMA project

The MMA project is a large-scale chemical project that has been launched again after many years in Puyang Park, Henan.
The MMA project adopts the first set of ethylene process technology in China, which opens up a new path for synthesizing MMA from coal chemical raw material gas and petrochemical production of ethylene.
The project will be completed in MMA.
The formation of its own unique competitive advantage in the industry field is of great significance for the sustainable development of Puyang Park, lengthening the industrial chain, and transforming and upgrading to high value-added chemical products
.

At present, the construction site of the MMA project is carrying out land acquisition boundary measurement and piling determination, which indicates that the new MMA project has finally started construction
.
MMA is the basic raw material for high-end materials such as aerospace, electronic information, optical fibers, optical lenses, and robots
.
China's MMA consumption ranks first in the world, its external dependence exceeds 60%, and the annual demand growth rate is higher than 10%.
It is one of the top ten products with the highest dependence on organic chemical imports
.

The MMA (methyl methacrylate) project is a large-scale chemical project launched in Puyang Park after many years.
The MMA project adopts the first set of ethylene process technology in China, which opens up a new path for the synthesis of MMA from coal chemical raw material gas and petrochemical production of ethylene.
The completion of the project will form its own unique competitive advantage in the MMA industry, which is of great significance for the sustainable development of Puyang Park, the extension of the industrial chain, and the transformation and upgrading of high value-added chemical products
.

The Institute of Process Engineering of the Chinese Academy of Sciences has been researching the technical route of ethylene-syngas production of MMA since 2010.
It started to operate stably in July and passed the 72-hour assessment organized by the Petrochemical Federation
.

More than 70% of the enterprises producing MMA in China use the hydrocyanic acid process, which is heavy in pollution, small in scale and poor in quality.
At the same time, each ton of MMA produces 1.
5 tons of cyanide-containing waste residue and 15 tons of refractory wastewater, which is difficult to treat.
In addition, the raw material hydrocyanic acid is a Highly toxic substances, the construction of hydrocyanic acid synthesis plant is restricted by various conditions such as technology, raw materials and environmental protection
.
Since 2010, the team has proposed the synthesis gas-ethylene synthesis MMA technology.
This technology uses synthesis gas and ethylene raw materials to produce MMA using a four-step method.
The process raw materials are in line with China's national conditions, the reaction process is relatively mild, and the three wastes in the process are less.
This process Extend the industrial chain of coal chemical industry
.

Technical Features

1) The new process uses syngas and ethylene as raw materials, a typical combination of coal chemical industry and petrochemical industry; 2) The developed new catalyst has good activity and stability, high conversion and selectivity; 3) The reaction conditions are relatively mild
.

In recent years, China's MMA consumption market has grown rapidly, and it has become the third largest consumer market in the world after the United States and Japan.
Statistics show that in 2017, China's apparent consumption of MMA was 1 million tons per year, with an external dependence of about 40%
.
This achievement uses abundant ethylene and synthesis gas as raw materials to synthesize MMA products, broadens the source of raw materials, extends the downstream industrial chain of coal chemical enterprises, and has broad application prospects

Henan Zhongke Puyuan New Materials Co.
, Ltd.
(hereinafter referred to as Zhongke Puyuan) was established in 2021.
It is jointly funded by Henan Zhongyuan Dahua Group Co.
, Ltd.
, Puyang Financial Holdings Co.
, Ltd.
, and Puyang Economic and Technological Development Zone Urban Construction Investment Co.
, Ltd.
, with a registered capital of 330 million yuan, is a holding subsidiary of Henan Zhongyuan Dahua Group Co.
, Ltd.
On the basis of the 1,000-ton MMA pilot project of Zhongyuan Dahua Company, Zhongke Puyuan plans to invest in the construction of 2 × 50,000 tons / Annual (Phase I 50,000 tons/year) ethylene production methyl methacrylate (MMA) project, the project uses ethylene as the main raw material, and uses CO and H ² generated from coal-based synthesis gas , and auxiliary uses methanol and formaldehyde to produce MMA
.

On March 9, 2022, Henan Zhongke Puyuan New Materials Co.
, Ltd.
2 × 50,000 tons/year (the first phase of 50,000 tons/year) ethylene production methyl methacrylate (MMA) project in Puyang Economic and Technological Development Zone Economic Development Bureau For the record, the project code is: 2203-410972-04-01-267235
.
The total investment of the project is 1.
932 billion yuan
.
In the first phase of the MMA project, a 50,000-ton/year unit will be constructed, and some public works will be constructed in the second phase; a 50,000-ton/year unit will be constructed in the second phase
.
After the completion of the two-phase project, the production capacity will eventually reach 100,000 tons/year
.

The raw material consumption of methanol, H ² and CO in the project is 67270t/a (9.
34t/h), 21.
06 million Nm ₃ /a ( 2925.
1Nm ₃ /h) and 19.
42 million Nm ₃ /a ( 2697.
2Nm ₃ /h) respectively
.

Henan Zhongyuan Dahua Group Co.
, Ltd.
currently has a low-pressure methanol synthesis unit in the plant area, with a designed methanol output of 300,000 tons/year, which can meet the project needs
.

The H ² and CO of the project come from Yongpuyang Yongjin Chemical Co.
, Ltd.
, which is managed by Zhongyuan Dahua Group.
² The designed output is 42,000Nm ₃ /h, and the designed CO output is 22,000Nm ₃ /h.
Under full load, the H ² and CO consumption of the Yongjin Chemical Plant are 40,140Nm ₃ /h and 21,360Nm ₃ /h.
However, in recent years, the prices of coal chemical products have fluctuated.
Fluctuations, the production capacity of the plant area has not achieved full-load operation, and the raw materials of the project can be supplied by adjusting the production load of the ethylene glycol unit in the Yongjin chemical plant area
.

The main equipment of the project is a set of 50,000 tons of MMA production equipment, and a set of 120,000 tons (37%) of formaldehyde equipment.
It consists of four reaction steps: condensation reaction, oxidation reaction and esterification reaction
