IPDI Production from Isophorone and Urea
IPDI Plant Capital & Operating Cost Analysis | United States | Q2 2025
This report presents the economics of Isophorone Diisocyanate (IPDI) production from isophorone and urea. The process examined is a typical non-phosgene technology. In this process, isophorone diamine (IPDA) is initially obtained from isophorone. Then, IPDA reacts with urea and butanol generating a carbamate intermediate. Then, the carbamate is thermally cracked producing IPDI.
The report provides a comprehensive study of IPDI production and related IPDI production cost, covering three key aspects: a complete description of the IPDI production process examined; an in-depth analysis of the related IPDI plant capital cost (Capex); and an evaluation of the respective IPDI plant operating costs (Opex).
The IPDI 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 IPDI 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 IPDI 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
IPDI. IPDI (a.k.a. Isophorone Diisocyanate) is one of the main aliphatic diisocyanates, being widely employed in polyurethanes production for coating applications. It is highly reactive, so it can undergo several addition reactions across the CN double bond in such a way that a myriad of commercial products can be obtained from reactions with alcohols, carboxylic acids, and amines.
Raw Materials
Urea. Urea is a nitrogen-rich fertilizer essential for modern agriculture. It is also used in the production of plastics, resins, and pharmaceuticals. Urea is synthesized from ammonia and carbon dioxide and is typically stored in solid granules or liquid form. Its widespread use in farming helps boost crop yields worldwide.
Isophorone. Isophorone (3,5,5-trimethyl-2-cyclohexen-1-one) is derived from the trimerization of acetone. More specifically, it is produced by the aldolization of acetone under alkaline conditions. This cyclic unsaturated ketone serves as solvent for a range of polymers, resins, fats, oils and agrochemicals. Although it has traditionally been used as a low volatility solvent, it is also an important industrial building block, as a raw material to produce isophorone diisocyanate (IPDI) for the production of light-stable polyurethane.

IPDI Production from Isophorone and Chlorine
This report presents the economics of Isophorone Diisocyanate (IPDI) from isophorone and chlorine in the United States. In the process examined, isophorone is reacted with hydrogen cyanide, generating IPN. IPN obtained is then reacted with ammonia to form IPNI, which is hydrogenated with more ammonia to yield IPDA. Finally, IPDA reacts with phosgene to produce IPDI. The phosgene used is generated from chlorine and carbon monoxide.

Granulated Urea Production from Ammonia (Self-Stripping Process)
This study approaches the economics of Granulated Urea production from ammonia and carbon dioxide in the United States through Saipem's (formerly Snamprogetti) ammonia stripping technology. In this process, ammonia and carbon dioxide are converted to Urea via ammonium carbamate intermediate. The non-converted carbamate is stripped from the Urea solution by excess ammonia and decomposed back to ammonia and carbon dioxide, which are recycled to the Urea synthesis.
