The project uses Tianyuan Company's two-stage hydrogenation and tail oil cracking technology with completely independent intellectual property rights, through the use of coal grading, the utilization of coke oven gas resources and the deep processing of coal tar, prolonging the industrial chain of coal chemical products and changing the The current state of coke-coking companies is not coke, high energy consumption, heavy pollution, low utilization of energy resources, and zero discharge of “three wastes†is achieved.
According to Mao Shiqiang, Chairman of Tianyuan Chemical Co., Ltd., the 500,000 tons/year low-temperature coal tar lightening project consists of 1.35 million tons of low-temperature coking, coke oven gas cooling purification and storage, hydrogen extraction and compression, delayed coking, coal tar Hydrogenation and oil fractionation units. The project relies on coal retorting technology which has been formed in Yulin City for a long time. It uses vertical furnace retort technology to produce blue charcoal, coal tar and coke oven gas, and then produces high-purity hydrogen by coke oven gas treatment, and then uses two-stage hydrogenation and tail oil cracking. The patented technology processes the catalytic hydrocracking of coal tar and finally produces fractionally distilled high value-added products such as -20 and -30 diesel, naphtha, and liquefied gas.
The project is designed to process 500,000 tons of coal tar per year, and can produce 400,000 tons of high-quality fuel oil, 0.8 million tons of liquefied gas, 80,000 tons of petroleum coke, 06,000 tons of liquid ammonia, and 0.2 million tons of sulphur per year to achieve sales revenue. 3 billion yuan. Compared with direct-coal and indirect oil-making of coal of the same scale, the project investment is only 1/6~1/5, the water consumption is 1/5~1/4, and the energy consumption can be reduced by 23%~27%. The 500,000-ton/year-scale facility can reduce CO2 243 million tons annually.
It is understood that the secondary hydrogenation, tail gas cracking low-temperature coal tar lightening technology was first developed by the private company - Shenmu Tianyuan Chemical Co., Ltd. In March 2008, the company built a 250,000 tons/year low-temperature coal tar lightening unit and produced a qualified fuel oil product in April that year. It was dubbed as “Yulin version of coal-based oil productionâ€. In October 2008, Shaanxi Coal Chemical Industry Group reorganized Shenmu Tianyuan Chemical Co., Ltd. and injected huge sums of money to organize experts to re-examine, study and improve the original technology, and exposed the operating flexibility of the original device during the actual operation process. , equipment safety and stability and other issues and design defects are optimized, improved and eliminated one by one, and ultimately the scale of production will be enlarged to 500,000 tons/year.
2. Mute effect: Bearing Steel mute, high strength, low noise
Yulin version of coal oil to achieve industrialization
On March 9th, the reporter learned from Shaanxi Coal Chemical Group that the world’s largest low-temperature coal tar lightening project—a total investment of RMB 1.7 billion in Shaanxi Coal Chemicals Group Co., Ltd. Yulin Jinjie Tianyuan Chemical Co., Ltd. 500,000 tons/year of low-temperature coal tar Catalytic hydrogenation to produce high-quality fuel oil projects, the official commissioning test, means that China's coal oil technology adds "new".
