This report presents a cost analysis of Propylene Oxide (PO) production from chemical grade (CG) propylene and chlorine. The process examined is a typical chlorohydrin process. In this process, propylene and chlorine first react to produce propylene chlorohydrin intermediate. Then, the chlorohydrin intermediate is dehydrochlorinated to Propylene Oxide. Dichloropropane is 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): "Propylene Oxide", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Chlorohydrination, Saponification, Calcium Oxide, CaO, Calcium Hydroxide, CHPO

The primary goal of this research was to find a renewable synthesis method for the production of propylene oxide. Significant quantities of glycerin are formed as a co-product when soybean oil is used to produce bio-diesel. This glycerin can be used to produce propylene glycol, which can undergo dehydration over basic catalysts to produce propylene oxide (PO), along with eight other products: acetaldehyde, propionaldehyde, acetone, 2-propanol, 1-propanol, allyl alcohol, acetol, and dipropylene glycol. A variety of catalysts were prepared for each set of reactions, and dehydration was carried out in a plug flow reactor. For this thesis, only three main catalysts are presented, such as Na/Al2O3 (sodium acetate on alumina), Cs-ETS-10, and Na acac/MgO (sodium acetyl acetonate on nanocrystalline MgO). Dehydration reactions were performed with different masses of catalyst, reactor temperatures, and residence times to optimize the selectivity to PO. The highest selectivity to PO was obtained as 12.33% for Na acac/MgO catalyst at 400_ C, 0.1g, and a N2 flow rate of 20SCCM. Even though Cs-ETS-10 catalyst was active for PO production, it also produced higher amounts of dipropylene glycol (80%). Dipropylene glycol appears to act as an active intermediate in the dehydration of propylene glycol to propylene oxide over Cs-ETS-10 catalyst, which would limit PO selectivity to 50%. The Na/Al2O3 resulted in low selectivity of 2% to PO, although it gave an appreciable selectivity of 60% to propionaldehyde. The reaction pathway to PO over these catalysts was also studied. Dehydration of propylene glycol to propylene oxide over Na/Al2O3, and Na acac/MgO catalysts appears to be a direct dehydration, rather than the involvement of a dipropylene glycol active intermediate.

This is a free full sample report offered by Intratec Solutions to demonstrate, in advance, the type of information you will get when you buy one of our reports, offering the same standard and structure (types of graphs, tables and descriptions) that you will find in all of our Cost Analysis Overview reports. This report presents alternatives for producing PG Propylene from different feedstocks and a cost comparison of these alternatives, across different countries. More specifically, the report compares the costs of PG Propylene production through the following pathways: * Pathway 1: Propylene Production from Light Naphtha * Pathway 2: Propylene Production from Ethylene and Butenes * Pathway 3: Propylene Production from Propane (with Hydrogen Generation) Pathway 1 corresponds to a steam cracker for Propylene production (ethylene as co-product). In Pathway 2, Propylene is produced via metathesis reaction of ethylene with 2-butene (present in raffinate-2 feedstock). In Pathway 3, propane is dehydrogenated to Propylene with hydrogen generated being valued as fuel. The analysis presented in this report includes: * A comparison of the economic potential of the pathways listed above in several countries, comprising: - Comparative analysis of capital costs - Comparative analysis of production costs * Comparison between product price and raw materials costs of each pathway - An overview of each production pathway, including: - Raw material(s) consumption figures and product(s) generated - Related technology licensors and block flow diagram of representative industrial processes Keywords: Propene, Ethene, Steam Cracking, PDH, Propane Dehydrogenation, Olefins Conversion Technology, OCT

This report presents a cost analysis of Propylene Oxide (PO) production from chemical grade (CG) propylene and isobutane using a tert-butyl hydroperoxide process. The process examined is similar to Huntsman process. In this process, isobutane is oxidized to produce t-butyl hydroperoxide, which reacts with propylene to produce Propylene Oxide. t-Butanol is generated as by-product in the process. This report was developed based essentially on the following reference(s): US Patent 5349072, issued to Texaco in 1994 (assigned to Huntsman in 2011) Keywords: Propene, Methylpropane, Oxidation, Epoxidation, TBHP, tert-Butyl Alcohol, TBA, PO/TBA

This report presents a cost analysis of Propylene Oxide (PO) production from polymer grade (PG) propylene and hydrogen peroxide. The process under analysis is similar to the hydrogen peroxide to Propylene Oxide (HPPO) process jointly developed by Evonik and Uhde. 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 20030092920, issued to Evonik Degussa GmbH in 2003 Keywords: Evonik, Degussa, Uhde, Oxidation, Epoxidation, HPPO
