Economic Study Of Light Hydrocarbon Project In Inner Mongolia Based On Environmental Value

China is a big country in energy production and consumption.Rapid economic growth has led to rapid growth in energy demand,and traditional energy production and consumption patterns are difficult to adapt to the current situation.This paper is based on the local rich coal raw materials,respectively,using coal water slurry gasification,catalytic gasification,hydrogenation,supporting low-temperature methanol washing,conversion,synthesis,stabilization of light hydrocarbons and other devices,with an annual output of 200,000 tons per year stable light hydrocarbons.The catalytic gasification and hydrogenation technology is a new gasification technology independently developed by Xinao Group.Through the implementation of industrial demonstration of the technology,the conversion efficiency of coal-to-gas energy is improved,pollutant emissions are reduced,and the development of national gasification technology is promoted.Coal catalytic gasification technology is an important way to clean and use coal.It uses coal catalytic gasification technology.Coal is at a lower temperature with water vapor and,and the composition of the gasifying agent is in the catalyst.The gasification reaction is carried out under catalysis to produce a high concentration of methane.The crude methane content of the outlet is greater than 20%,up to 24%,and the methane yield per kg of carbon is above 0.5%.At the same time,due to the endothermic reaction of gasification in the furnace and the exothermic reaction of methanation,the process oxygen Consumption and heat loss are lower than traditional coal-to-methane technology.Firstly,it introduces the research status and existing problems of economic benefit evaluation of domestic and foreign projects,expounds the research purpose,theoretical significance and application value of the thesis,and determines the research content,technical route and research methods of the thesis.Secondly,through the background analysis of the market and price,the detailed description of stable light hydrocarbons,liquefied natural gas and liquefied petroleum gas,and the principles of economics,provided a theory for the economic benefit evaluation of Inner Mongolia light hydrocarbon projects basis.Then,through the selection of the site plan with relevant economic conditions and reasonable traffic conditions,the layout,technical and economic indicators,transportation volume and transportation plan of the public works are first introduced,and then the scale of the heating project and the heating plan are carried out.The project's economic benefits are evaluated in terms of profitability,liquidity,break-even analysis and sensitivity analysis,and the risks faced by the project are clarified.The results show that the total investment return rate of the project is 22.15%,which is greater than the benchmark investment return rate of 12%.The financial status of each year is stable and the liquidity is good.In terms of sensitivity analysis,raw material prices and product prices benefit the project.The impact is the most sensitive,followed by variable costs and investment;the break-even point of capacity utilization rate is 39.06%,indicating that the project has better anti-risk ability.Based on the above analysis,the project is financially feasible.Finally,in the economically viable on the basis of analysis of the environmental impacts of the project.Integarated Project reality,the value of pollutants from technical energy saving value,govemance and climate optimum value analysis,a scientific evaluation ofenviron mental value and impact.Calculation know,the sewage treatment capacity of 2.88 million per year,atmosphere control 2.2032 billion cubic metre.Through the recycling of solid waste treatment 123.46 tonne.Pollution control projectsbetter.Technical energy saving value of the item of 38.4822 million,treatment of sewage value of 460 800,governing atmospheric value of 3.4811 million.The economic value of 78 000 for solid waste management,climate optimum value of 1.0689 million.Stability of light hydrocarbon projects environmental value of 43.571 million.Description of the environmental value of the more obvious,to make the project more competitive,advanced and forward-looking.
