Hexamethyldisiloxane Production

This report presents the economics of Hexamethyldisiloxane production. The process examined is a typical trimethylchlorosilane hydrolysis. In this plant, trimethylchlorosilane is submitted to a hydrolysis, yielding Hexamethyldisiloxane product.

The report provides a comprehensive study of Siloxanes production and related Siloxanes production cost, covering three key aspects: a complete description of the Siloxanes production process examined; an in-depth analysis of the related Siloxanes plant capital cost (Capex); and an evaluation of the respective Siloxanes plant operating costs (Opex).

The Siloxanes production process description includes a block flow diagram (BFD), an overview of the industrial site installations, detailing both the process unit and the necessary infrastructure, process consumption figures and comprehensive process flow diagrams (PFD). The Siloxanes plant capital cost analysis breaks down the Capex by plant cost (i.e., ISBL, OSBL and Contingency); owner's cost; working capital; and costs incurred during industrial plant commissioning and start-up. The Siloxanes plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.
