"The information integration project for air pollutants control in outlying islands’ industrial zone this year has started since May, 09, 2014. The main tasks of the project are the following. Firstly, securing the existing or potential Volatile Organic Compounds in the industrial zone of high pollution and transport conditions of local air mass, to adopt the precautionary strategies effectively. Secondly, employing material information of the plants in the industrial zone to establish the fingerprint information of pollutants, and adopting Chemical Mass Balance;CMB) model to analysis pollution sources of each receptor point. Furthermore, the project continues updating, maintaining and expanding the function of the existing environmental monitoring system. Besides, self-management of air pollution and reduction plan of each company and the results tracking are integrated. Finally, air pollutants checking and controlling plan of outlying islands industrial zone are provided to Environmental Protection Bureau Yunlin County for their education and technical training. The implementation results of this year project are as follows:1. Investigating the Volatile Organic Compounds The industrial area of VOCs sampling in Sixth Naphtha Cracking Plant had been tested 72 times, A zone (Haifeng area) pollutant concentrations range between 205.8 and 5004.61g / m3, and B zone (Mailiao area) pollutant concentrations range between 201.14 and 3938.62 g / m3. Through the results of the total concentration graph in the two main areas and the ground wind field graph, the influence of the 9 sampling points in each area by the wind direction and velocity can be derived. The high concentration sampling points were found in the downwind position mostly. It is not only impacted by the pollutants from upwind position, but also the pollutants from the nearby plants. The pollutants not easy to accumulate in high wind speed therefore the pollution concentration relatively low.2. Chemical Mass Balance receptor model (CMB-8.2) analogWe adopted CMB-8.2 receptor model to stimulate VOCs contribution ratio of nine sampling points in the industrial area of off-shore Island. CMB-8.2 simulation results show that the main source of pollution contribution of A zone(Haifeng area) has four factories, namely synthetic resin or plastic process of ChangChun artificial plant (A9 contribution accounted for 74%), synthetic phenol plant (A9 contribution accounted for 79.8%), styrene third plants (A1 contribution accounts for 54%) and n-butanol plant (A5 contribution accounts for 50%) ; the main source of pollution contribution of B zone (Mailiao area) has three factories, namely epoxy resin plant (B3 contribution accounted for 33.4%), high density polyethylene plant (B4 contribution accounted for 36.5%) and a polystyrene plant (B8 contribution accounted for 40.2%).3. The further checking and testing by the scholars and experts There are four sessions of further checking and testing by the scholars and experts this year. The target company in the first session is M01(OL-2 department), M02(OL-3 department), M10 of Formosa Petrochemical Corporation Mailiao Branch on June 12-13,2014. The target company in the second session is M01(PHENOL department), M02(PHENOL department), M14(ARO-2 department), M15(ARO-2 department), M16(ARO-2 department) of Formosa Chemicals & Fiber Corporation Haifong Branch on October 13-14, 2014. The target company in the third session is MA1(MMA department), M91(C4 department), M92(C4 department) of Formosa Plastics Corporation Mailiao Branch on November 24-25, 2014. Finally, the target company in the fourth session is M01 of Dairen Chemical Corporation, M01 of ChangChun Plastics Corporation, M01 of ChangChun Petrochemical Corporation on November 27-28, 2014. There are 184 suggestions from the committee members in total, including 76..." |
