Recently, the reporter learned that gas chemical enterprises are stepping up their efforts to deploy coal chemical industry in response to the problem of "suffering gas."
“At present, natural gas supply is still not returning to normal levels, and our two methanol plants and 150,000 tons/year acetic acid plant were forced to stop production. With the current methanol price hitting record highs during the year, the lack of natural gas supply has brought about The loss is undoubtedly huge.†On December 12, Song Yuqi, general manager of Shaanxi Yulin Weather Chemical Co., Ltd., reluctantly told reporters. He said that with the increasing demand for natural gas in China, the shortage of natural gas in western chemical companies may still appear. In order to effectively resolve this risk, Lutianhua is making every effort to promote the construction of a 1.4 million-ton/year coal-to-methanol project and strive to complete and put into production in advance. As this project is also supported by a coal mine, after the completion of the project, not only will the company's raw material supply be guaranteed, but the cost will also be greatly reduced.
At the same time as the project construction, Lutianhua also designed a transmission pipeline. In the future, the surplus carbon monoxide from the coal chemical plant can be transported to the existing natural gas chemical plant, realizing natural gas chemical industry with “lower hydrogen and more carbon†and coal chemical industry. The advantages of “small†complement each other, while increasing the production of methanol and acetic acid, reducing energy consumption and carbon dioxide emissions, it can also reduce the adverse impact of insufficient natural gas supply on enterprises.
Guizhou Chitianhua Co., Ltd. also took the development of coal chemical industry as an effective measure to deal with natural gas shortages. Chen Qiujing, deputy manager of the company’s sales company, told reporters: “This year is the worst year for natural gas since Chitianhua built the plant. It is expected that annual production will be reduced by nearly one-fifth of previous years.†Recently, they also received notification from the gas supplier. The supply of gas for industrial production may also decrease. In order to do long-term plans, following the joint construction of a 300,000-ton/year coal-to-synthetic ammonia and 150,000-ton/year dimethyl ether project with Guizhou Hongfu Industrial Development Co., Ltd. in August 2005, they recently started a total investment of 40.53. Billion RMB 1.12 billion cubic meters per year coal gasification and 500,000 tons per year alcohol ammonia cogeneration large coal chemical project. "Once these projects are completed and put into production, they will effectively resolve the operational risks that the shortage of natural gas brings to enterprises." Chen Qiujing said.
The sudden "gas shortage" made Shaanxi Xinghua Group, which had not previously suffered the "short breath," strengthen its confidence in building coal chemical industry. The person in charge of the company stated that although Xinghua Group encountered only a short period of 10 days for the "short breath," the current air supply volume has returned to about 85% of its normal level, and this "gas shortage" has not produced production and operation of the company. Too much of an impact, but the "gas shortage" is still a wake-up call for businesses. At present, the company has strengthened its determination and confidence in accelerating the joint development of coal chemical plants and coal chemical industry and natural gas chemical industry. With a total investment of 3.4 billion yuan, Xinghua Group's 300,000 tons/year coal-synthetic ammonia, 300,000 tons/year methanol, 300,000 tons/year soda ash, and 300,000 tons/year ammonium chloride and other coal chemical projects are fully promoted. It was completed and put into production in 2011.
Subsequently, they will also launch projects such as methylamine/DMF and adipic acid, which will enable Xinghua Group to achieve production capacity of 800,000 tons/year of alcohol ammonia and 800,000 tons/year of ammonium nitrate, thus realizing the Xinghua Group from a single fertilizer company to comprehensive Chemical companies, from natural gas chemical industry to natural gas, coal chemical industry, compound chemical industry.
Shaanxi Yanchang Petroleum (Group) Co., Ltd. also formulated countermeasures for potential risks of insufficient supply of gas. In the company's "Twelfth Five-Year Plan", not only large-scale petrochemicals and oilfield gas chemical projects within the chemical parks of Jingbian, Yanheng and Yan'an were planned, but coal chemical projects were also planned simultaneously.
“The reason for the simultaneous planning of coal, gas, and petrochemical projects is to realize the docking and coupling of three different processes and to achieve deep optimization and configuration of different resources and different production factors to achieve coal chemical, petrochemical and oil field gasification. The advantages are complementary to each other, significantly increasing resource utilization rate and conversion rate, and reducing emissions of waste gas, waste slag, and waste water. At the same time, this design can effectively prevent any unit failure or raw material supply problem from causing fluctuations and parking of the entire device, and realize the long device length. Cycle, continuous, and stable operation at high load, said Li Dapeng, assistant to General Manager of Yanchang Petroleum (Group) Co., Ltd., with confidence.

A Pu system for shoe soles refers to the use of polyurethane (PU) material in the manufacturing of shoe soles. PU is a versatile and durable material that offers several advantages for shoe soles.
Here are some key features and benefits of using a PU system for shoe soles:
1. Cushioning: PU provides excellent cushioning and shock absorption properties, making it ideal for footwear that requires high levels of comfort and impact protection.
2. Lightweight: PU is a lightweight material, which helps reduce the overall weight of the shoe, making it more comfortable to wear and reducing fatigue during extended use.
3. Flexibility: PU offers good flexibility, allowing the shoe sole to bend and flex with the natural movement of the foot. This enhances comfort and prevents stiffness or discomfort during walking or running.
4. Durability: PU is highly durable and resistant to wear and tear, making it suitable for long-lasting shoe soles. It can withstand repeated use and exposure to various environmental conditions without losing its structural integrity.
5. Slip resistance: PU can be formulated with specific additives to enhance its slip resistance properties, providing better traction and grip on different surfaces. This is especially important for safety footwear or shoes used in slippery conditions.
6. Design versatility: PU can be molded into various shapes and designs, allowing for greater design flexibility and customization options for shoe soles. This enables manufacturers to create unique and visually appealing footwear.
7. Water resistance: PU can be made water-resistant or waterproof, which helps protect the shoe sole and the foot from moisture, rain, or other wet conditions.
Overall, a PU system for shoe soles offers a combination of comfort, durability, flexibility, and design versatility, making it a popular choice for footwear manufacturers and consumers alike.
