This report was developed based essentially on the following reference(s): Keywords: PER, polyol, neopolyol esters, Formalin, silver catalyst, Uhde Inventa Fischer, EMS, formaldehyde solution, incomplete conversion




LLDPE Production via Slurry Process - Cost Analysis - LLDPE E21A


Book Description

This report presents a cost analysis of Linear Low Density Polyethylene (LLDPE) production from polymer grade (PG) ethylene and 1-hexene using a slurry process. The process examined is similar to Chevron Phillips 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): (1) US Patent 20120282144, issued to Chevron in 2012; (2) US Patent 7629421, issued to Chevron in 2009 Keywords: Ethene, PE, Isobutane, Slurry Reactor, Loop Reactor




Sodium Polyacrylate Production Process - Cost Analysis - Sodium Polyacrylate E21A


Book Description

This report presents a cost analysis of Sodium Polyacrylate production from glacial acrylic acid and sodium hydroxide. In this process, acrylic acid is partially neutralized by sodium hydroxide, yielding a solution of sodium acrylate monomers, which is subsequently polymerized to Sodium Polyacrylate.
