Book Description
This report presents a cost analysis of Polymer Grade (PG) Propylene production from methanol using a methanol-to-propylene (MTP) process. The process examined is similar to Lurgi MTP process. This process is carried out in two steps: first, methanol is converted to dimethyl ether (DME), and then DME is converted to Propylene. Gasoline is also generated as by-product in the process. 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): US Patent 20100063337, issued to Lurgi in 2010 Keywords: PG Propylene, Methyl Alcohol, Propene, On-Purpose Propylene Production
