Abstract: The coal chemical industry is facing environmental protection, carbon emission reduction and preservation pressure, and needs to be transformed and upgraded. Coal-to-nature gas factories can adjust the door-to-door industrial routes to increase pure air quality without affecting the main products, adding a high-value sub-product to coal chemical companies, but there is no description of how gas can transcend regional transportation. It describes the air liquefaction, the gas filling data, and the luggage he helped her move when she entered school. He also wanted to pass the feasibility and advantage of her three technical routes of pipe rolling, and with the help of the vigorous development of the hydrogen energy industry, he realized the transformation and upgrading of the coal chemical industry. As a coal country, our country’s coal resources are rich and easy to obtain. Based on our existing dynamic structure, for a long time in the future, coal will still be our country’s main force and occupy a major position in ensuring the safety of our country’s dynamic supply. There are one type of modern coal chemical products, with multiple technical routes coexisting, including coal-to-emission, coal-to-oil, coal-to-chemical products, etc. Currently, the investment in coal chemical projects is very large, and the profitability is difficult. Many coal chemical projects in China are in a difficult situation. The completed coal-to-oil and coal-to-emission projects have been continuously invested in large quantities, and the future prospects of coal-based chemical companies are difficult to express. The coal-based chemical industry is facing environmental protection, carbon emission reduction, and capital pressure. Therefore, if modern coal chemical industry wants to achieve sustainable development, it should find the industry positioning based on its own characteristics, couple technical routes and optimize systems, and reduce costs.
In the industrial gas-making circuit, the advantages of coal-to-hydrogen production are obvious: (1) Raw materials are easy to obtain, my country’s coal resources are rich and easy to obtain; (2) The gas-to-hydrogen production cost is low, and the standardized coal-to-hydrogen production cost is 0.8 yuan/m3, while the natural gas-to-hydrogen production cost is 2 yuan/m3; (3) The technology is mature, and the technology of coal-to-hydrogen production is ripe. href=”https://philippines-sugar.net/”>Pinay escort can be traced back to the 1980s and 1990s. Overall, coal-based thermal energy routes are the most economical and practical ways. Hydrogen energy has the characteristics of cleaning, efficient and sustainable development. It is a preface to the transformation of various dynamic products such as electricity, liquid fuel, heat, etc., and is a unique way to achieve cross-power network coordination and optimization in the future. Hydrogen (H2) is a secondary force, which requires the conversion of primary force, and is compared with existing hydrogen control methods such as electrolysis and natural gas. Our country’s resource resources mainly based on coal is Sugar babyThe development of coal-to-hydrogen hydrate has laid the foundation for the transformation of coal chemical enterprises, and also provides new development goals for the purpose of transformation.
There is no document to adjust the specific craft routes of coal chemical enterprises. In the future, Sugar daddy can be used in large scale applications. Coal chemical companies can adjust the industrial routes, extend the industry links, etc. without changing the main product, and find the fit point with the thermal energy. href=”https://philippines-sugar.net/”>Pinay escort, strengthening the risk-resisting ability. This article takes the coal-to-natural gas project as an example to explore the feasibility of the new coal-to-pure pure gas technology route for enterprises, and hopes to provide enterprise transformation and development for reference.
1 Preparation of hydroxide
Taking coal to natural atmosphere as an example, coal is finally born with natural atmosphere through coal pressure, cooling, decomposition of gas, methanation and decomposition. See Figure 1 for details.
Figure 1 Coal-to-natural gas industrial art line representation diagram
Based on existing technology, on the basis of the natural gas of the main product, the decomposition atmosphere after partial purification can be derived. The important component content is shown in Table 1. The new PSA device can increase pure added value and humidity.
Table 1 Scores of important components of decomposition atmosphere
From Table 1, we can see that the H2 content in the decomposition gas is high, the sulfur content is low, and the base does not contain benzene, powder and other complex materials, which is conducive to the operation of downstream PSA pure device. Moreover, the pure CH4 can be directly and entered into the natural gas outer conduit and transported to the target market.
2 Hydrogen energy transportation
Hydrogen energy generally requires trans-regional transportation. The coal-to-natural gas project is usually located in the southeastern region and is transported to downstream users of Dongmen through the West China East Transportation Pipeline. If the transportation is directly driven through a long pipe, the transportation cost is high, and the project does not have competitive advantages, so the demand will be Escort ManilaAir temperature is processed in one step, so that the final product has the advantage of cost-effectiveness. The above three technical routes are selected for investigation.
2.1 Liquid line
Pinay escort is used to reduce the temperature to 20.37K and turn it into liquid through pre-cooling and expansion flow. href=”https://philippines-sugar.net/”>Sugar babyHydrogen. Liquid has two advantages: ① The single-car sluggishness of liquid is more than 10 times that of air. Not only does the transportation efficiency have greatly improved, but the cost of liquid is far greater than that of air; ② The gas can be purely purified by liquefaction; at a low temperature of 20.37K, all gas complications except a few rare gases will condense, so that the Sugar with a pristineness of ≥5N (99.999%) can be obtained. daddyHigh pure air and super pure air with 6N (99.9999%) or above, 5N and 6N hydrogen have wide application prospects. my country consumes about 200,000 t/a. Today, it is used in large quantities in large-scale integrated circuit chips, tablet displays, semiconductor devices, metallurgy and other industries, and is also highly pure., Super pure market prices are much higher than those of the common Escort, and the added value of liquid is much higher than that of air. Based on the above liquid water advantages, enterprises can add liquid water products with higher added value in the factory. The liquid-hydraulic ratio of coal-to-nature gas factory has the following advantages: the coal-to-nature gas factory covers a large area and usually leaves space for the later scale expansion. Therefore, the newly added liquid-hydraulic device does not require additional land acquisition, which can save land prices; sufficient application of existing public projects of the factory such as meter air, nitrogen, and salt water; the liquid-hydraulic chemical industry requires liquid nitrogen for pre-cooling, and the factory has air-distribution devices, and the resulting liquid nitrogen can meet the liquid-hydraulic unit Sugar daddy application; the liquid slurry project has a relatively large electricity consumption, and the liquid slurry energy consumption is 13kwh/kg (slurry). The factory has built an automatic electric factory. The liquefaction can be used for the factory and the electricity cost is low. The above advantages can clearly show the production cost of reducing liquid temperature, and the liquid temperature produced by coal-to-natural gas factories is more competitive. Ordinary liquids can be transported by road tanks, and the demand can be doubled and the economy of the deep-cooled iron trough is biting cold, and the snow in the community has not melted. Cars or sea transport are transported; one of the liquid cooling routes in Japan (Japan) today is to use lignite gasification to make, purified gas, liquid cooling, and liquid transportation to the port of Japan (Japan) in Australia. This plan is under trial. In comparison, in addition to highway and railway transportation, liquids produced in western my country can also be selected to transport through the Changjiang Waterway to the east through the Yangtze River Waterway. my country is also encouraging universities and enterprises to develop demonstration applications of technology and industryization in the liquid thermal field, and accelerate the development of the liquid thermal market. In the future, liquid thermal will play the main color in the Chinese thermal energy industry chain.
