EXECUTIVE SUMMARY OPTIMISTIC ORGANIC Sdn. Bhd. (OOSB) is currently operating a 30 000 tn/yr Maleic Anhydride (MA) production facility in the Teluk Kalong Industrial Estate (TKIE) in Kemaman, Terengganu. The following EIA and QRA reports related to OOSB MA complex have been done and submitted to DOE: I. Environmental Impact Assessment (EIA) for the Proposed TLC Industries (M) Sdn. Bhd. Maleic Anhydride Plant in Kemaman, Terengganu, Malaysia,1995. II. Preliminary Risk Assessment for the Proposed TLC Industries (M) Sdn. Bhd. Maleic Anhydride Plant in Kemaman, Terengganu, Malaysia,1995. III. Supplementary EIA Report for Incinerator for the Proposed TLC Industries (M) Sdn. Bhd. Maleic Anhydride Plant in Kemaman, Terengganu, Malaysia,1995. Over the years of operation, demand for these products is more than it was originally foreseen. In order to meet this demand, OOSB are planning to upgrade the plant capacity of existing plant at additional 33% to 40 000 tn/yr. This will involve installation of additional equipment and revamping of existing equipment. .All new equipment will be constructed within the current plant boundary. PROJECT TITLE The title of this report is Environmental Impact Assessment (EIA) for the Proposed Maleic Anhydride Plant Expansion in KawasanPerindustrianTeluk Kalong, Kemaman, Terengganu. STATEMENT OF NEED The proposed facility expansion is toincrease the production of Maleic Anhydride (MA) to meet the increasing worldwide demand for this important petrochemical product which is used in coatings, adhesives, resins, paints, plasticisers, insecticides and food chemical worldwide.

The proposed plant expansion shall be established on the existing facility on a 12.5 ha parcel land located at the north end of industrial estate. The TKIE is located less than 1 km from Kemaman Port, which has adequate facilities to handle the raw materials if required. The TKIE is approximately 8 km north of the Chukai Town. Kuantan is located 68 km while Kuala Terengganu is located 140 km to north. The location for the proposed project location is shown in Figure ES-1.

The MA facility is built to operate using n-butane as feed stock. Figure ES-4andFigure ES-5show the n-butane plant and the existing and future mass balancefor the Proposed Maleic Anhydride Plant Expansion. The process involves the gas phase oxidation of raw butane in the presence of air with a fixed bed catalyst to form crude MA (CMA). Five per cent of CMA is condensed and separated The remaining CMA remains in gas phase with the other reaction gas products and inert gases. This CMA is recovered by washing the vapour with water to form maleic acid solution. This solution is dehydrated using orthoxylene to form CMA and fumaric acid. The CMA produced from the dehydration is recombined with the condensed CMA and purified using distillation process. The fumaric acid is separated as a by-product after the dehydration process. The main raw materials for the plant are mixed butane. At past the plant was operated with benzene as a feed stock and now the raw material changed from benzene to n-butane. For this process the raw butane (mixed butane) is sourced from PETRONAS. Mixed butane supplied through pipeline passing by the side of the plant. The raw butane separation and subsequent conversion technology has been supplied by UOP. Table ES-1: List of Raw Materials and Finished Products A.

Page Exe - 4 EIA for the Proposed Maleic Anhydride Plant Expansion in Teluk Kalong Industrial Estate, Kemaman,Terengganu Executive Summary The combustion products from the burner are injected with steam to minimise smoke generation. The hot gases then pass through a series of 8 heat exchangers before they are vented to the atmosphere through a stack. The heat removed from the vented gases is used to preheat air used in the incinerator and generate steam. There will be no expansion in the existing thermal Incinerator, as the existing design is sufficient to cater for an additional feed rate.The plant will be taken shut-down automatically when the incinerator fails (as per Process Control System and Procedure) as to run Oxidation (Reactors) Plant, it is mandatory to have the thermal Incinerator running.

The new loading however is still much below than the design capacity of the existing treatment plant. Figure ES-3shows the water balance and volume that will be sent to the treatment plant before and after expansion.
