Book Description
This report presents a cost analysis of Precipitated Calcium Carbonate (PCC) production from lime and sodium carbonate. The process examined is a conventional lime-soda process. In this process, calcium hydroxide is generated by treating lime (calcium oxide) with water. Then, calcium hydroxide reacts with soda ash (sodium carbonate) forming sodium hydroxide and Calcium Carbonate. Precipitated Calcium Carbonate, in solid form, and sodium hydroxide solution (50 wt%) are obtained as final products. This report was developed based essentially on the following reference(s): Keywords: Hydrated Lime, Slaked Lime, Slake, Calcium Oxide, Lime-Soda Process

Book Description
This report presents a cost analysis of caustic soda flakes production from a caustic soda solution (50 wt%). In this process, caustic soda is concentrated to about 99 wt% in a specially designed evaporator and the resulting melt is fed by gravity to a flaking machine, where it is cooled and processed into flakes. This report was developed based essentially on the following reference(s): "Sodium Hydroxide", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Chlor-Alkali, Caustic Soda, NaOH, Caustic Flakes

Book Description
This report presents a cost analysis of Precipitated Calcium Carbonate (PCC) production from lime. In this typical process, lime reacts with water producing calcium hydroxide, which is further carbonated with carbon dioxide from calcination to produce PCC. This report was developed based essentially on the following reference(s): (1) US Patent 6251356, issued to G. R. International in 2001 (assigned to Pacific Nano Products in 2015) (2) US Patent 3920800, issued to Cyprus Mines Corporation in 1975 Keywords: Hydrated Lime, Slaked Lime, Slake, Calcium Oxide, Quicklime

Book Description
This report presents a cost analysis of Precipitated Calcium Carbonate (PCC) production from limestone. In this typical process, limestone is first calcinated. The product reacts with water producing calcium hydroxide, which is further carbonated with carbon dioxide from calcination to produce PCC. 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 6251356, issued to G. R. International in 2001 (assigned to Pacific Nano Products in 2015) (2) US Patent 3920800, issued to Cyprus Mines Corporation in 1975 Keywords: Calcite, Aragonite, Calcine, Hydrated Lime, Slaked Lime

Book Description
Research Paper (postgraduate) from the year 2013 in the subject Engineering - Chemical Engineering, , course: Chemical Engineering, language: English, abstract: There is a lot of wastage of calcium chloride going on daily and lot of valuable resources are being wasted. If this continues and any solution is not provided then this problem can prove to be very vital for the industry. Based on this study we look forward to design a major project based on recovery of calcium chloride, which will be fruitful to the industry to solve this setback and hence will be profit making concept. The focus on recovery of calcium chloride and minimizing the problem can lead to significant cost savings and industrial growth. Our solution provides the methods for recovery of calcium chloride from which evaporative crystallization process is very economical and efficient process. The final product will be in flake form (calcium chloride dehydrate) having 78 - 80% purity. It can be further dried to get calcium chloride anhydrous having purity level of 94%.The main advantage of this system is physical form of product (non dusty) and the cost of operation is far less as compared to conventional drying systems. The present demand for the calcium chloride is estimated at 53 tons per annum. The demand is expected to reach at 137.5 tones by the year 2018. The calcium chloride recovery from Solvay’s process solution succeeds in addressing all of these requirements where previous efforts have failed.

Book Description
This report presents a cost analysis of Calcium Hypochlorite production from slaked lime, sodium hydroxide and chlorine The process examined is a typical sodium process. This process consists mainly in passing chlorine into a slurry of slaked lime and sodium hydroxide, generating Calcium Hypochlorite and sodium chloride. After separation steps, Calcium Hypochlorite (about 70 wt%) and an aqueous solution of sodium chloride are obtained as products. This report was developed based essentially on the following reference(s): (1) US Patent 4390512, issued to PPG Industries, Inc., in 1983 (2) US Patent 4428919, issued to PPG Industries, Inc., in 1984 Keywords: Caustic Soda, Calcium Salt, Bleaching Powder, Chlorination, Sodium Method, Slaked Lime

Book Description
This report presents a cost analysis of Diphenyl Carbonate (DPC) production from phenol. The process examined is similar to Ube process. In this process, dimethyl oxalate (DMO) intermediate is initially produced from methanol. Then, DMO reacts with phenol to produce diphenyl oxalate (DPO), which is finally decarbonylated to DPC. This report was developed based essentially on the following reference(s): US Patent 5892089, issued to Ube in 1999 Keywords: Phenyl Carbonate, Carbonylation, Liquid-Phase Decarbonylation, Carbon Monoxide
