Abstract
The purpose of this paper is to make an economic evaluation of chemical construction projects on environmental impact. By analyzing the serious pollution and damage caused by the chemical industry, the construction project of chemical industry is analyzed, while reasonable and effective evaluation indexes and methods are established. Cost benefit method was used for the analysis. The index system for economic evaluation of chemical construction project was established, including environmental cost index and environmental benefit index. According to the method of economic evaluation of environmental impact of chemical construction project, each index is calculated, and the calculation formula of the index is obtained. Finally, it is applied to the project of ethylene expansion and extension project in chemical plant. The experiment result shows that the economic benefit is obviously lower than the economic benefit of environmental impact assessment. Based on the above finding, it is concluded that the feasibility of the evaluation method is verified and satisfactory results are obtained, which show that the economic evaluation of the environmental impact of chemical construction projects is feasible.
