Issue 27/2015 - Low temperature distillation technology opens up a new way for clean and efficient coal utilization

After 7 years of research, Henan Longcheng Group, a private enterprise, has developed a low-grade coal low-temperature dry distillation fractionation utilization technology and put it into large-scale industrial application
.
Experts pointed out that once the technology is popularized and applied, it will leapfrog China's coal utilization efficiency, release huge energy conservation and emission reduction benefits, and obtain the "dividend"
of a significant increase in oil and gas self-sufficiency.

At present, 80% of China's total coal is directly burned, causing serious environmental pollution, and wasting the oil, gas and other resources contained in coal, and it is urgent to open up a new road
for clean and efficient use of coal.

In October 2011, Longcheng Group officially put into operation
a set of 300,000 tons of coal grading, separation and clean and efficient utilization plant located in Xixia County, Henan Province.
Since March 2014, the 10 million ton project with a total investment of more than 4 billion yuan in Caofeidian, Hebei Province has started trial production
.
This technology is like "sesame oil", "extruding" the oil and gas in the coal, and this physical process improves the quality of
the coal.

Low-temperature dry distillation can also realize kerosene gas and electricity multigeneration, producing greater economic and social benefits
.
At present, the cost of refined oil in the petrochemical industry is 4270 yuan / ton, the cost of direct liquefaction of coal is 3957 yuan / ton, while the cost of Longcheng low-temperature dry distillation technology is only 1724 yuan / ton; The cost of natural gas to LNG is about 1.
77 yuan / cubic meter, the cost of coal to gas is about 2.
1 yuan, and the cost of Longcheng low-temperature dry distillation technology is only 1.
57 yuan
.
Its energy saving and emission reduction benefits are remarkable, and the desulfurization rate in the dry distillation process reaches 98%.
