PP PROCESS DESCRIPTION UNIPOL? PP工艺过程描述 1 Description of the Contract Plant 合同工厂描述 The Contract Plant consists of a polypropylene process unit designed to produce 400 KTA of pelleted polypropylene from propylene based on UNIPOL? PP Technology licensed by Union Carbide Chemicals Plastics Technology LLC, a subsidiary of The Dow Chemical Company. The UNIPOL PP Process is a low-pressure gas-phase fluidized bed process for the manufacture of PP resins. 合同工厂包含一套基于UNIPOL? PP 技术的生产40万吨/年的聚丙烯工艺装置，该技术转让自陶氏化学公司下属的联合碳化物（联碳）化学和塑料技术公司。 UNIPOL? PP 工艺技术是一项用于生产聚丙烯树脂的低压气相流化床工艺。 In addition to the UNIPOL PP Process, resin handling and blending facilities are also included in the Contract Plant battery limits. Other auxiliary facilities include utility distribution, flare and plant infrastructure systems. The PDP provides adequate information to allow these systems to be easily designed by the Engineering Contractor, resulting in savings to the Licensee. The product bagging area is outside the Contract Plant battery limits and will be designed by the Licensee. 在UNIPOL? PP 工艺之外，树脂处理和掺混也包括在本合同工厂范围之内. 其他辅助工艺设施包括公用工程分配，火炬，工厂基础设施。工艺包提供了足够的信息使工程承包商能很容易的设计这些系统,从而使专利受让方节省投资. 产品包装区域是在合同工厂之外，由该技术买方设计。 2 UNIPOL PP Process Unit UNIPOL聚丙烯工艺装置 The UNIPOL PP plant ISBL is comprised of the following process areas. UNIPOL聚丙烯工厂界区由下列工艺单元组成： A. Raw Material Supply and Purification 原料供应和精制 B. Propylene Purification　丙烯精制 C. Reaction聚合反应 D. Resin Degassing树脂脱气 E. Vent Recovery尾气回收 F. Resin Additive Handling添加剂的加入 G. Pelleting造粒 Each is described in detail in the following sections. No catalyst preparation is necessary – SHAC? catalyst is delivered to the plant ready to use. No gas/solid separation is needed due to the unique design of the reactor and product discharge system. The process units listed above are included in
