Book Description
This report presents a cost analysis of polymer grade (PG) Ethylene production from light naphtha feedstock using a typical steam cracking process. In this process, naphtha is thermally cracked at low severity conditions, maximizing propylene to Ethylene ratio. Besides PG Ethylene and PG propylene, the process also generates pygas and a mixed C4s stream as by-products. This report examines one-time costs associated with the construction of a United States-based plant and the continuing costs associated with the daily operation of such a plant. More specifically, it discusses: * Capital Investment, broken down by: - Total fixed capital required, divided in production unit (ISBL); infrastructure (OSBL) and contingency - Alternative perspective on the total fixed capital, divided in direct costs, indirect costs and contingency - Working capital and costs incurred during industrial plant commissioning and start-up * Production cost, broken down by: - Manufacturing variable costs (raw materials, utilities) - Manufacturing fixed costs (maintenance costs, operating charges, plant overhead, local taxes and insurance) - Depreciation and corporate overhead costs * Raw materials consumption, products generation and labor requirements * Process block flow diagram and description of industrial site installations (production unit and infrastructure) This report was developed based essentially on the following reference(s): "Ethylene", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Ethene, Propene, Pyrolysis Gasoline, Hydrocarbon Pyrolysis, Cracking Furnace, Lummus, KBR, Technip, Linde, S&W
