China Chemical News: RTP Group Extended Oil Coal, Oil and Gas Comprehensive Utilization Sets a Benchmark for Energy Saving and Carbon Reduction

In Jingbian, Shaanxi Province, located at the southern edge of the Mauwusu Desert, is located a large and unique modern chemical enterprise - Shaanxi Yanchang China Coal Yulin Energy Chemical Co. Founded more than 10 years ago, Yanchang Petrochemical Company has not only successfully harnessed the world's first comprehensive utilization device of coal, oil and gas resources, realized the deep coupling development of coal chemical industry and oil and gas chemical industry, maximized the efficiency of resource utilization, energy saving and carbon reduction, but also insisted on innovation-driven and structure adjustment, developed high-end, differentiated and customized polyolefin products, and helped promote high-quality development.

The year 2021 was an extraordinary and milestone year in the development history of Shaanxi Yanchang China Coal Yulin Energy Chemical Company Limited (hereinafter referred to as YNCC).

In this year, YNCC produced 1,856,700 tons of polyolefin products, achieved sales revenue of 16.011 billion yuan, profit of 1.647 billion yuan and tax of 2.018 billion yuan, all indicators hit a record high, and achieved a steady start and a high point in the 14th Five-Year Plan.

In this year, YNCC's new Phase I start-up project entered into stable trial production, reaching design performance 2 months earlier than planned, and operating at a level better than similar domestic plants. Under the situation of soaring coal price, it took only 6 months to achieve positive revenue trial, contributing benefits of 1.246 billion yuan.

In this year, the quality and efficiency of new product research and development of YNCC went hand in hand, and the efficiency of medium and high-end products increased by 108 million yuan, among which ethylene vinyl acetate copolymer (EVA) foam and EVA for photovoltaic encapsulation film filled the blank in the northwest region, and the product efficiency generation capacity was significantly enhanced.

One figure fully demonstrates the advantages of YUNENGHUA's innovative coal, oil and gas resources comprehensive utilization project.

The project uses coal, oilfield gas and residual oil as raw materials to produce polyolefin and is built in two phases. One of the phase I start-up projects mainly includes 1.8 million tons of methanol (annual capacity, same below), 1.5 million tons of residue oil catalytic thermal cracking, 600,000 tons of methanol to olefin (DMTO) plant, 600,000 tons of polyethylene, 600,000 tons of polypropylene, etc., which was officially put into operation in July 2014. The first phase of the filling project is to build 1.8 million tons of methanol combined plant, 600,000 tons of DMTO plant, 300,000 tons of low density polyethylene/ethylene vinyl acetate copolymer (LDPE/EVA) integrated plant, 400,000 tons of polypropylene plant, etc., which will be put into operation in December 2020. So far, after the completion of the first phase of coal, oil and gas resources comprehensive utilization project with a total investment of nearly 40 billion yuan, the total production capacity of polyolefin of YNCC reaches 1.9 million tons, which is the largest scale of non-petrochemical routes in China.

"Yanchang Petroleum Group made a scientific decision to adopt the new technology of comprehensive utilization of coal, oil and gas for the first time at home and abroad. In hindsight, the decision at that time was very forward-looking, catering to both the current industrial policy and the coal, oil and gas resource endowment of Yanchang Petroleum to the fullest extent." Li Wei, Secretary of the Party Committee and Chairman of the Board of Directors of YNCC, said in an interview with reporters.
