China is a country with multiple coals, lean oil, and low gas. At present, 80% of China’s total coal is directly burned, causing serious environmental pollution and wasting resources such as oil and gas in coal. It is urgent to open up a new road for clean and efficient use of coal. .
It is understood that Long Cheng's cryogenic retorting technology is to continuously heat the coal to a certain temperature under the condition of isolated air, so that the low-rank coals such as lignite and long flame coal can be transformed into clean coal, low-temperature coal tar and coal gas, etc. Typical coal fractionation and utilization technology. In September 2014, the technology passed the scientific and technological achievements appraisal organized by the China National Petroleum and Chemical Industry Federation with 5 academicians. The conclusion was: "This technology has completely independent intellectual property rights and has reached the international advanced level."
In October 2011, a 300,000-ton coal graded clean, high-efficiency utilization facility of the Longcheng Group in Xixia County, Henan Province was formally operated. Since March 2014, trial production has begun at 10 million tons/year of a total investment of over 4 billion yuan in Hebei Caofeidian, and 12 sets of equipment with a scale of 870,000 tons/year have run smoothly. Zhu Shucheng, chairman of Longcheng Group, said: "This technology, like 'seed oil,' 'presses' oil and gas out of coal, and after this physical process, it also improves the quality of coal compared to other coal grade points. Quality utilization technology, which has taken the lead in industrialization, large-scale and long-term stable operation worldwide."
At the Caofeidian project site, in a 450,000-ton coal bunker with a dome, the raw coal was sent to a side-suspended, rotating giant “kiln†through an enclosed conveyor belt. The outer side of the “kiln†was covered with fuel pipes and the heat was Into the "kiln" to ensure that the coal in the anaerobic distillation.
The technical personnel introduced that this "kiln" type rotary bed integrates many technical innovations and has overcome two major world-class technical problems: high-temperature rotary dynamic sealing and cascaded heating intelligent temperature control. From September 16 to September 18, 2014, the experts of the China Petroleum and Chemical Industry Federation organized an on-site calibration. The processing capacity of the single set of equipment reached 100 tons/hour, the clean coal yield reached 71.53%, and the coal tar yield was 11.05. %, the gas yield was 9.87%. Coal tar and gas can be changed into gasoline, diesel and liquefied natural gas through subsequent processing.
The project leader, Chao Guochao, said that the two currently operating units “eat†4,800 tons of long-burning coal every day, producing 3,600 tons of clean coal, more than 480 tons of coal tar, and 380,000 cubic meters of gas, and selling steel that is hundreds of kilometers in radius and Tar processing company.
Low-temperature dry distillation not only allows the coal to turn white and clear, but also enables coal-fired electricity and electricity to be co-produced, resulting in greater economic and social benefits. At present, the cost of petroleum products in the petrochemical industry is 4,270 yuan per ton, the cost of directly liquefied refined coal products is 3,957 yuan per ton, and the cost of Longcheng retort technology is only 1,724 yuan per ton; the cost of LNG produced by natural gas is about 1.77 yuan per cubic meter. The gas production costs about 2.1 yuan, and Longcheng's cryogenic distillation technology is only 1.57 yuan. What is more valuable is its remarkable energy-saving and emission reduction benefits. In the process of retorting, the desulfurization rate reaches 98%.
Zheng Xinli, executive vice chairman of the China International Economic Exchange Center, said that the economic value, strategic value, environmental value, and feasibility of Long Cheng Technology have gone far beyond other technical paths.
Some experts have calculated the "big account" of China's clean and efficient use of coal through the "small account" of the comprehensive benefits of the smelting technology of smelting gas.
The first is to increase oil and gas self-sufficiency and strengthen energy security. In 2013, the national coal consumption was about 3.65 billion tons, and low-rank coal consumption was about 2 billion tons. If Longcheng technology is used, 1.4 billion tons of clean coal, 143 million tons of fuel oil, and 84 million tons of natural gas can be proposed from the low-rank coal consumed in the country each year, which is of far-reaching significance in reducing the long-term reliance on imports of China's oil and natural gas.
According to a survey conducted by the China Coal Industry Association, China has proven reserves of 875.832 billion tons of low-grade coal, which contains about 65.7 billion tons of oil and 51 trillion cubic meters of natural gas. This is 20 times that of China's proven oil recoverable reserves. As many as 11 times of the recoverable reserves of natural gas are ascertained. If Longcheng technology is used for processing, these “big coal fields†are equal to “big oil fields†and “gas fieldsâ€.
The second is to promote energy-saving and emission reduction and form new strategic industries. If the dragon's cryogenic retorting technology can be further promoted, it can change the coal's single industrial structure for power generation, form a strategic emerging industry chain for clean and efficient use of coal, and then nurture and form new economic growth points.
Some experts pointed out that the large-scale promotion of Longcheng technology faces a “dilemmaâ€: First, financing difficulties. Only one project needs more than 4 billion yuan of funds, and large-scale promotion across the country will require up to tens of billions of dollars. In the absence of policy support for intellectual property pledge loans and coal clean and efficient use industries, Longcheng technology has difficulty obtaining credit support. The second is the difficulty of joint promotion. It is the best choice for Longcheng Group to build demonstration projects with upstream coal enterprises and downstream power companies. However, it is difficult to break the ice because of differences in ownership of enterprises and lack of policy guidance.
In September last year, the China International Economic Exchange Center, after conducting an in-depth study of the simmering technology, recommended the “Longcheng Low-Tempered Coal Dry Separation Utilization Technology Industry Promotion Research Reportâ€: “The state responds to this type of revolution. Innovative technologies give a high degree of attention, increase support and incorporate it into the national '13th Five-Year Plan' to promote industrial demonstration and enable it to be transformed into realistic productivity as soon as possible.â€
On April 27th, the National Energy Administration issued the "Coal Clean and Efficient Utilization Action Plan (2015-2020)", which explicitly included the use of coal as a major product route for middle-low temperature dry distillation gas and oil production as a major product classification step-by-step. Coal clean and efficient utilization strategy. It also put forward a clear goal of "2017 breakthrough in key technologies for upgrading low-grade coal grades; and 2020, setting up a batch of multi-million-ton grade quality improvement demonstration projects".
The product line, process technology and project progress of Longcheng low-rank coal low-temperature dry distillation oil production and gas utilization technology are highly in line with the “Coal Clean and Efficient Utilization Action Plan (2015-2020)â€, which indicates that Longcheng technology has risen. For the national energy development strategy.
Low-temperature dry distillation technology opens up a new road for clean and efficient use of coal
After 7 years of research, the private enterprise Henan Longcheng Group has developed low-grade coal cryogenic distillation fractionation and utilization technologies and has invested in large-scale industrial applications. Experts pointed out that once the technology is promoted and applied, it will improve China's coal utilization efficiency by leaps and bounds, release huge energy-saving and emission-reduction benefits, and obtain a “dividend†in which the self-sufficiency rate of oil and gas is greatly increased.
