Manufacturing Industry's Winter Sorrow: You changed coal to gas and I changed it! When you're done, tell me if you're angry

Zhao Benshan said that the saddest thing in a person's life is that he is still alive and his money is gone. But for many manufacturing enterprises, this kind of sadness appeared this winter: you changed coal to gas, I changed it, and after the change, you told me that the gas was gone! Since the State Council issued the 'Air Pollution Prevention and Control Action Plan' on September 10, 2013, policies related to air pollution control have been successively introduced across the country.“coal to gas”boom, many businesses“gritted teeth”Replaced coal-fired boilers with gas-fired boilers. However, when the coal-to-gas conversion ended, many companies found that the supply of natural gas was not sufficient.“out of food”became normal. Especially after the arrival of the heating season, natural gas supply in Shandong, Hebei and other places has been cut off one after another, and some companies have fallen into the embarrassing situation of eating a meal without a meal. In Langfang City, Hebei Province, 449 companies have recently stopped production and limited production. According to the 'China Natural Gas Development Report (2017)', in 2016, the domestic natural gas production was 136.9 billion cubic meters, a year-on-year increase of 1.7%. In 2016, China imported 72.1 billion cubic meters of natural gas, accounting for 35.0% of the total consumption. According to statistics, in the first half of 2017, my country's natural gas consumption was 114.6 billion cubic meters, a year-on-year increase of 15.2%. In fact, the country's annual natural gas supply is only about 200 billion cubic meters, of which 2/3 is used for civil use, and only about 60 billion cubic meters of industrial gas. As a result, since the beginning of winter, all regions and gas-using industries have been shouting“lack of air”, all in“be angry”. Even Xinjiang, Sichuan, Qinghai, and Shaanxi are guarding“atmospheric basin”the western region is shouting“not enough gas”. The latest data from the National Bureau of Statistics shows that in early December 2017, LNG prices rose by 23.6%, or 1,330.4 yuan per ton, compared with late November. According to media reports, Chinese gas importers are rushing to buy natural gas supplies, and this demand has pushed up LNG prices in Asia to a three-year high. How to solve“Panic”question? (1) Promoting the construction of underground gas storages and enhancing peaking capacity Natural gas consumption has obvious seasonality, and natural gas peaking mainly relies on underground gas storages, LNG and natural gas fields, etc. At present, the number of underground gas storages in my country is only less than 20 seat. At the same time, my country's natural gas price mechanism has not yet been clarified, and enterprises lack the motivation to build underground gas storage. The country should speed up the reform of natural gas prices and let the market determine the price, so as to facilitate the construction of commercial reserves and finally solve the problem of gas shortage in winter. (2) Development of unconventional natural gas as supplement On the basis of expanding conventional natural gas production, it can be supplemented by the development of unconventional natural gas such as shale gas, tight gas, and coal-to-gas. However, under the current circumstances, due to the low permeability of shale gas reservoirs, the difficulty of mining, and the unformed development technology, the development investment is high, the output is low, the investment recovery is slow, and the initial investment and output are seriously imbalanced. To a certain extent, it affects the enthusiasm of enterprises to develop shale gas. The state should clarify the shale gas resource tax rate as soon as possible, implement preferential policies for shale gas resource tax reduction and exemption, temporarily exempt or reduce shale gas resource tax, increase the enthusiasm of mining companies and social capital to explore and develop shale gas, and promote shale gas The industry will develop rapidly and rapidly, and the structure of natural gas supply in my country will be adjusted. (3) Gas is suitable for gas, and coal is suitable for coal. Under the pressure of smog, coal is not useless, and natural gas is not absolutely clean. Natural gas and coal, both fossil energy sources, have a problem of clean combustion. The poor combustion of natural gas will also bring about the control of nitrogen oxides, and nitrogen oxides are not conducive to the expulsion of smog. And coal is not for nothing. The progress of coal use technology at home and abroad has proved that coal can be completely used in a clean manner, and the pollutants emitted into the atmosphere when using advanced coal clean utilization technology can be greatly reduced or even meet the same requirements as when using natural gas. whether“coal to gas”still“gas to coal”, should proceed from the actual situation, adjust measures according to local conditions, gas should be gas, coal should be coal.
