At 0:00 on April 12th, the 50 kt/y medium-temperature coal tar lightening project of Shaanxi Coal Industry Chemical Group Shenmu Tianyuan Chemical Co., Ltd., the largest single coal tar lightening unit in China, was successfully launched and produced. Qualified oil products. The quality of light coal tar 1# product reached the -35 diesel standard and the "EU IV" emission standard; the light coal tar 2# product was of good quality.
The project adopts patented technology and pretreatment patent technology for medium-high temperature coal tar hydrocracking with completely independent intellectual property rights, with a total investment of 1.7 billion yuan. It is the largest domestic coal tar deep processing industry, the most advanced production technology, and exemplary energy efficiency. Conversion project. The project annually processes 500,000 tons of coal tar, 1.35 million tons of blue carbon, 308,000 tons of light coal tar, 80,000 tons of petroleum coke, and other products such as liquefied gas, sulfur, and liquid ammonia, with an output value of over 3 billion yuan.
The Phase I project (250 thousand tons/year) of medium-high temperature coal tar lightening project of Shaanxi Coal Coal Chemical Group Shenmu Tianyuan Chemical Co., Ltd., which undertook the project, was completed and put into operation in April 2008, and all products met the standard. Known as "Yulin version of coal to oil."
In October 2008, the company added 750,000 tons/year of blue charcoal and pretreatment equipment on the basis of the phase I plant, and transformed and optimized the original plant, resulting in a single set of annual processing of 500,000 tons of coal tar. The scale of production. They effectively solved the problem of large energy consumption and large water consumption in the coal chemical industry, achieved industrial water recycling, energy consumption and water consumption amounted to only about one-fourth of the same-scale projects, and the “three wastes†achieved zero emissions.
