Coal chemical makes for environmental protection economy
Industrial worker's devotion
Cen Xuanyi, head of Jiutai Energy Inner Mongolia Co's electrical engineering department, is in charge of 16 maintenance workers, as well as safety checks and equipment operations at nine production sections and life zones in the northern area.
Cen said that the electrical engineering department carries an extensive range of responsibilities and heavy workload with complex and delicate details. Cen often warns coworkers to pay attention to small details.
The power distribution cabinet at each work section directly matters to the normal operation of production equipment, so Cen will pay extra attention to electric-related facilities in daily routine inspection. He upholds the work principle of more maintenance and less repair.
The company sits in the new Dalu district of Ordos' Jungar Banner and is a wholly-owned subsidiary of Jiutai Energy. It covers an area of 73.3 hectares, began construction in August 2007 and went into operation in October 2010. Now, the company has 1,380 employees and can produce 1 million tons of methane and 100,000 tons of dimethyl ether.
Cen never slacks off no matter how trivial and complex the work is.
He urges others and himself to pursue quality and keep improving. Legendary rise of coal chemical industry
The new Dalu district is a main coal chemical development area in Erdos. It is home to towering plants and a well-developed transportation network. The district has produced one coal chemical legend after another.
Jiutai Energy started its business in Shandong's Linyi in 2002, and now the company has many subsidiaries in Shandong, Inner Mongolia, Guangdong and Beijing. The branch in Inner Mongolia has seen the most robust growth among its peers.
The branch features green trees and artistic sculptures, instead of towering plants and blackened chimneys. The afforestation rate exceeds 30 percent, making it hard to believe that the branch engages in heavy chemical operations.
Walking into the production zone under closed-off management, one can see clean production with internationalization standards, efficient modern control using cutting-edge technology, accurate and strict militarized management, and a clean and comfortable production workshop, all reflecting the branch company's management level and development strength.
A new round of western development has begun. China unveiled guidance to support Inner Mongolia's development. The autonomous region's development strategy has been determined, and Baotou, Hohhot and Erdos have been integrated. Things have sped up in Ordos' path to become a national major development area, creating a blueprint for the new Dalu district to become a key industrial park. By the end of 2015, a 10-million-ton coal chemical base will be built here to satisfy the energy needs of Beijing, Tianjin and Hebei. The district will also become an economic and cultural center of Jungar Banner. In such a context, Cui Lianguo, chairman of Jiutai Energy, boldly proposed a strategic plan of building the Jiutai chemical park in Inner Mongolia.
This is not only growth for a company, but also a park and a region.
Good news from coal to oil production
Coal deep processing can produce not only methanol, but also diesel oil, liquid paraffin and liquefied gas.
In May 2002, Yitai Group invested 18 million yuan ($2.93 million) and worked with the Institute of Coal Chemistry of the Chinese Academy of Sciences to develop coal-based synthetic oil slurry reactor technology, making inroads into coal-to-oil field.
Yitai's coal-to-oil project is an extension of China's national 863 high-tech project and the coal-based liquid fuel synthetic pulp reactor industrialization technology, a CAS innovation project.
The project's main products cover Fischer-Tropsch synthesis diesel, stable light hydrocarbon, liquefied gas and liquid paraffin. Diesel products are clean fuel that contain very little sulfur, carbon residue, ash and low chromaticity. Tests show that diesel exhaust emissions meet Europe's¢õstandard.
To date, the company has 20 patents for utility models authorized by the State Intellectual Property Office, and a total of six patents for inventions are under review. The company was named one of the top high-tech enterprises in August 2013.
Yitai's coal-to-oil project is the first production line of China's coal indirect liquefaction independent technology industrialization and is important for enterprises to undertake risks of national major project research, development and industrialization. The project is also important in accelerating implementation of China's national coal-to-oil energy strategy.
Demonstration base construction
As a big coal province, Inner Mongolia has continued to adjust its industrial structure, extend its industrial chain, optimize its industrial layout and transform its development model in recent years. It has gone against the global economic recession and economic downward pressure in the autonomous region and carved out a new industrialization path using coal to produce power, chemicals and metallurgy.
In February 2005, Shenhua's direct coal liquefaction project began construction. The project is the world's first direct coal liquefaction industrialization unit. The project managed to put out qualified diesel oil and naphtha on Dec 31, 2008. In 2012, a total of 865,000 tons of oil products were produced.
In May 2006, Yitai's coal indirect liquefaction project, China's first synthetic oil unit with independent intellectual property rights, in the new Dalu district, began construction. The first bucket of qualified oil products was produced on March 27, 2009.
Datang Doren's 460,000-ton coal to olefin project began construction in 2006. On March 16, 2012, the company officially went into trial production. As of Dec 20, 2012, a total of 393,000 tons of fine methanol and 66,000 tons of polypropylene were produced.
On August 30, 2009, Datang Keqi's 4-billion-cubic-meter coal-to-natural gas project, the first of its kind, began construction. The first phase methanation device went into operation smoothly and put out qualified natural gas on July 28, 2012, marking the completion of technical process construction.
Other major projects include Shenhua Baotou's coal-to-olefin project and Tongliao GEM Chemical's 200,000-ton ethylene glycol project. Such major and good projects have helped Inner Mongolia build a modern coal chemical production demonstration facility.
Inner Mongolia is speeding up senior coal chemical technical personnel introduction and professional coal chemical technology development. It has actively boosted and planned construction of an outward coal chemical products transportation channel and built a rapid and convenient transportation channel to ensure industrialized coal chemical development.
Looking back on the coal chemical industry's development in recent years, the development of Inner Mongolia has shifted from basic chemical raw materials to high-tech chemical products, from primary chemical products to high value-added high-end chemical products, and from extensive production to a resource-saving and environmentally-friendly model.
In recent years, the autonomous region has insisted on experimentation and demonstration. It continues to improve existing technology and equipment; strive for national support in gasification, purification, synthesis experimentation and domestic production of large-scale equipment; improve coal deep processing technology and equipment; and extend the industry chain to help more experimented and demonstrated technologies take root in Inner Mongolia. The region has focused on industrialization development. After the success of experimented and demonstrated projects, the follow-up project must be in place in time. Experiment and demonstration have to be scaled up, and a new production line should be built in short order to ensure positive results.
