Study On Post Evaluation Of Preparation Of Natural Gas By Coke Oven Gas Project In H Company

H company has abundant coke oven gas resources,especially the production of phase IV coke oven project,which makes the coke oven gas spare more.In order to effectively use these coke oven gas and make comprehensive use of it,H company invested in the construction of the project of preparation of natural gas by coke oven gas.As a clean environmental protection project encouraged and supported by the state,it not only solves the outlet problem of coke oven gas,but also improves the added value and comprehensive utilization rate of products.However,it remains to be discussed whether the project has good economic benefits,how long the project investment can recover the cost,how the project goes into operation and the sustainability of the project.Therefore,it is necessary to conduct post-evaluation research on the project.Based on the project of preparation of natural gas by coke oven gas as the research subject,this paper first introduces the background and significance of the research and probes into the development status of post-evaluation at home and abroad.Secondly,on the basis of the relevant theories of post-evaluation,the meaning,characteristics,content and significance of post-evaluation of chemical engineering projects are further studied.Thirdly,the methods of comparative analysis,survey interview method and empirical analysis were adopted to comprehensively analyze the preliminary feasibility study,construction and implementation,production and operation,process technology,economic benefits,environmental protection benefits and social impacts of the project of preparation of natural gas by coke oven gas in H company.It is concluded that it's a technologically advanced and clean environmental project and the overall operation and management of the project is good.Finally,it shows that the project of preparation of natural gas by coke oven gas in H company is successful in terms of economic,environmental and social impact post evaluation and it provides the real data support and the theory discussion for the establishment,construction and production operation of the project of preparation of natural gas by coke oven gas in the chemical industry in the future.At the same time,combined with the post-evaluation practice of the project of preparation of natural gas by coke oven gas in H company,some development Suggestions were put forward to the project construction management and the post-evaluation of the project from the enterprise,the industry and the government,so as to provide a reference for the future post-evaluation of new project or technical reform project.
