Toluene Diisocyanate from Toluene (Reductive Carbonylation)

This report presents the economics of Toluene Diisocyanate (TDI) production from toluene in the United States. The process examined is a typical reductive carbonylation. Initially, dinitrotoluene (DNT) is produced via toluene dinitration, which is then reacted with carbon monoxide and methanol to form toluene dimethylcarbamate. This intermediate is thermally decomposed to produce TDI.

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

The Toluene Diisocyanate 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 Toluene Diisocyanate 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 Toluene Diisocyanate plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.
