Liaohe Petrochemical Company, The Introduction Of Gasoline Etherification Technology Investment Decisions

State General Bureau of Environmental Protection approved the national standard of automobile-used unleaded petrol" in June of 1999. The standard is GB17930-1999. The index most difficult to reach is the content of olefin in this standard. In Liaohe Petrifaction Company of Petrochina(LPCP), The output of catalysis petrol is 400,000 tons every year. The content of olefin in the petrol of catalysis is 55%, which can't reach the standard of new petrol ( 35%) . From July 1,2003, the petrol product of the company can't be sold on the market directly as the qualified motor petrol. The Liaohe Petrifaction Company of Petrochina and Chinese Petroleum Joint-stock Company (CPJC)will suffer the enormous economic losses when the time comes. So looking for the most economic methods how to reduce the contents of olefin of petrol and reduce loss is the most urgent thing now.This paper utilize operations research, technological economics and the project management knowledge, Combine one's own reality of work, Analyses the investment decision from the respects, such as technology, economy and social benefit, etc. At the first, according the contrast analysis of olefin technology between domestic and abroad, draw out the project to choose. Then at the base of qualitative analysis, utilize the model of multi-objective hierarchy fuzzy decision to carry through the quantitative contrast evaluate among the three decision, then choose the satisfying scheme accord with Liaohe Petrifaction Company of Petrochina from those.This text carries through investment decision analysis about technology indraught of petrol etherification of Liaohe Petrifaction Company.And combines company reality to draw up feasible and optimal petrol etherification technology project in some aspects which including technology, economic and social benefit. This gives the evidence of decision to the leader, and chooses good way to reduce olefin of petrol for Liaohe Petrifaction Company, furthermore Chinese Petroleum Joint-stock Company, and give a quantitative evaluated method proper for choosing of projects.
