Aiming at the harsh environmental situation at present, refinery and chemical enterprises in China are mostly of high energy consumption and high pollution enterprises, which have great emission reduction potential of atmospheric pollutants. Based on SO2and NOx produced by refinery and chemical enterprises, the emission reduction potential optimization model is established by using linear programming method, and combined environmental management policy about total amount control of atmospheric pollutants. Through the model results, the maximum pollutant emission reduction of SO2and NOx predicted through the model were 4810.69 and 1574.04 (tons), and the optimum technical schemes have been given, respectively. This model could provide not only the maximum emission reduction of the existing projects and enterprises, but also the decision support of emission reduction for refinery and chemical enterprises during "the 12thFive Year Plan".

According to the indicator layer of the total amount control evaluation index system, this paper applied the management policy about the total control of regional atmospheric pollution to set up an optimization model for total amount control of regional atmospheric pollutants and get the minimum total cost of emission reduction. Through the model results, the total cost of reduction in instance case was 124.61 (108 yuan), and the membership of SO2 and NOX predicted through the model were 32.34 and 24.13 (104 tons), respectively. This model could be used as the technique and theory guider for the total amount control of atmospheric pollutants, to achieve the goals of the "12th Five-Year Plan" environmental protection requirement more effectively.

Index Evaluation

Refinery and chemical enterprises in China are mostly of high energy consumption and high pollution enterprises, so that greenhouse gases, SO2, NOX, NH3-N, and COD have great emission reduction potential. At the present stage, refinery enterprises emission reduction potential just for a pollutant is not comprehensive enough. Based on the above-mentioned five pollutants of refinery and chemical enterprises, the pollution reduction potential model are established by using linear programming method, which can provide decision support of emission reduction for refinery and chemical enterprises during the "12th Five Year Plan". The comprehensive index evaluation method not only can be used to clean production evaluation about evaluation of the environmental impact of large-scale integrated refinery project, also can be used to clean production audit of existing projects and enterprises to implement cleaner production performance evaluation.

Aiming at the harsh environmental situation at present, this paper applied the interval fuzzy linear programming method, and combines environmental management policy about the total control of regional atmospheric pollution, to set up an optimization model for total amount control of regional atmospheric pollutants under uncertainty. Through the model results, the total cost of reduction in instance case was [119.98, 125.82] (108yuan), and the membership of SO2and NOXpredicted through the model were [31.00, 32.64] and [23.62, 25.94] (104tons), respectively. This model could get the minimum total cost of emission reduction, and be used as the technique and theory guider for the total amount control of atmospheric pollutants.

AbstractIndustrial parks contribute greatly to China’s economic development while emitting huge air pollutants. It is necessary to study the characteristics of air pollutant emissions in industrial parks. In this study, emission inventories for 11 industrial parks were established. Meanwhile, the source emission and spatial distribution characteristics of the industrial park were analyzed. The cluster analysis was used to classify these parks into “4Hs”, “Mixed” and “4Ls” parks. “4Hs”, “Mixed” and “4Ls” represent that the levels of energy intensity, economic proportion of energy-intensive industries, coal proportion and pollution performance value are high, medium and low in turn. Then three emission reduction measures were set up to estimate the emission reduction potential and environmental impacts. The results show that: (1) the emissions of SO2, NOx, CO, PM10, PM2.5, VOCs and NH3 of 11 industrial parks in 2017 were 11.2, 23.1, 30.8, 8.3, 3.5, 5.1, and 1.1 kt, respectively. (2) Power plants were the largest source of SO2 and NOx emissions, and industrial processes were the largest emission source of CO, PM10, PM2.5, VOCs and NH3. (3) “4Hs” parks with traditional energy-intensive industries as the leading industries should be the emphasis of air pollutant emission reduction. (4) Through the optimal emission reduction measures, SO2, NOx, PM10, PM2.5 and VOCs were reduced by 81, 46, 51, 46 and 77%, respectively. Environmental impact reductions include 1.6 kt SO2eq acidified gas emissions, 1.4 kt PO43−eq eutrophication substances, 4.2 kt PM10eq atmospheric particulate emissions, 7.0 kt 1,4-DCEeq human toxic substances, and 5.2 kt PM2.5 eq breathing Inorganic. This study is helpful to understand the characteristics of air pollutants emissions in industrial parks and promotes the proposal and implementation of air pollutant emissions reduction strategies.
