Octamethylcyclotetrasiloxane Production
Siloxanes Operating Costs & Plant Construction Costs
This report presents the economics of Octamethylcyclotetrasiloxane production via dimethyldichlorosilanes hydrolysis. The study assumes a conventional plant located in the United States receiving a feed of dimethyldichlorosilanes. Cyclization is performed by heating the hydrolysis mixture with potassium hydroxide.
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.

Product
Octamethylcyclotetrasiloxane. Octamethylcyclotetrasiloxane (a.k.a. D4) is a cyclic silicone compound widely used as an intermediate in the production of silicone polymers, resins, and elastomers. Its application spans industries such as personal care, medical devices, and electronics. Octamethylcyclotetrasiloxane is synthesized from silicon, oxygen, and methyl groups, and it is typically stored as a liquid at room temperature. Its volatility and reactivity make it a key component in producing silicone-based products.
Raw Material
Dimethyldichlorosilane. Dimethyldichlorosilane is an organosilicon compound used as a starting material for silicone polymers and resins. It reacts with water to form silanols, leading to silicone production. Manufactured from methyl chloride and silicon, it is stored as a colorless liquid. Its role in creating silicones is fundamental for applications in sealants, adhesives, and medical devices.
