New Development Mode of Coal Chemical Industry in China

China is currently the world’s largest coal producer and consumer. The development of coal chemical industry is of great significance in adjusting China's energy structure, alleviating the pressure on foreign oil dependence, and diversifying petrochemical chemical raw materials.

In recent years, China has achieved a series of technological and equipment breakthroughs in the field of coal chemical industry. The output of traditional coal chemical products such as coke, calcium carbide, coal-synthetic ammonia, and methanol ranks first in the world. New coal gasification, coal-to-methanol and dimethyl ether technologies have also matured, and China has become the largest country in the coal chemical industry. The development of China's coal chemical industry during the "12th Five-Year Plan" period will become an important part of China's energy structure.

From December 6th to 8th, the 2012 China International Coal Chemical Exhibition and Development Forum hosted by China Petroleum and Chemical Industry Federation and China Coal Industry Association was held in Beijing. In this China's most advanced and authoritative coal chemical exchange platform, GE demonstrated its solutions in the coal chemical industry, covering the upstream/downstream coal chemical industry, including coal gasification, compression technology, denitrification technology and water treatment. technology. At the forum, GE gave keynote speeches on “The Breakthrough of Coal Water Slurry Technology”, “Application of Advanced Compression Technology in Coal Chemical Industry” and “GE Water Treatment Coal Chemical Solution and Case Analysis” to strengthen The technical exchanges and cooperation of all parties will jointly promote the sustainable development of China's coal chemical industry.

Gasification technology is the basis for the development of downstream industries of coal chemical industry. It can replace many processes that normally can only use natural gas as a feed material, can handle feeds such as coal and petroleum coke, and produce various high value-added products for power generation and heat and power generation. Production, as well as the production of hydrogen, ammonia, methanol and other chemicals. GE gasification technology is mature and reliable, and its environmental performance is superior. When this technology is used in the field of power generation (ie IGCC), compared with conventional coal-fired power plants, nitrogen oxide emissions are reduced by 33%, * oxide emissions are reduced by 75%, respirable particulate emissions are reduced by 40%, and carbon dioxide is captured. Set conditions. The exhibition will introduce the latest breakthroughs in gasification technology – greater gasifiers, high-pressure gasification, and better adaptability of coal types, thereby reducing customer investment by 10-15% and optimising gasification effects;

The development of a new coal chemical industry requires a low-carbon, environmentally-friendly development model. GE water treatment technology adopts a combination of chemical treatment and equipment processing to realize wastewater treatment, reuse of neutral water, and zero liquid discharge through pretreatment, depth reduction, depth reuse, and evaporation crystallization. The MBR with the latest water treatment membrane bioreactor, MBR with Macarrier, has excellent effluent quality, low membrane fouling, high COD removal rate and strong impact resistance, and can better meet the needs of the water treatment industry in the coal chemical industry; GE denitrification technology With 30 years of experience in denitrification and retrofitting, it has more than 60 patents for denitrification and emission reduction, and the total capacity of all types of denitrification and transformation units exceeds 19,000 MW. GE provides Chinese customers with denitrification, emission reduction and combustion optimization services to achieve one-stop service for fuel inspection and treatment, combustion control and optimization, flue gas treatment and performance optimization.

GE Oil & Gas provides various types of compressors, gas turbines, steam turbines, pumps, valves and other equipment for the downstream coal chemical industry. It is widely used in the gasification and power generation of coal gasification, synthetic urea, methanol and MTP, and hydrogen. deal with. Extending the Group's largest methanol synthesis project in the world, Ningmei Group's largest methanol-to-propylene project in the world, Shenhua Group's coal-to-oil phase II project and Sinopec Zhongtian Hechuang's world's largest LDPE project. All of GE's related equipment are silent in important positions. Work out.
