Laurolactam Production from Cyclododecanone
Laurolactam Operating Costs & Plant Construction Costs
This report presents the economics of Laurolactam production from cyclododecanone. The process examined involves the oximation of cyclododecanone raw material and the subsequent rearrengement of the cyclododecanone oxime formed to yield Laurolactam. The economic analysis performed assumes a plant located in the United States.
The report provides a comprehensive study of Laurolactam production and related Laurolactam production cost, covering three key aspects: a complete description of the Laurolactam production process examined; an in-depth analysis of the related Laurolactam plant capital cost (Capex); and an evaluation of the respective Laurolactam plant operating costs (Opex).
The Laurolactam 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 Laurolactam 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 Laurolactam plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.

The process under analysis comprises four major sections: (1) Cyclododecanone Oximation; and (2) Oxime Rearrangement.
Cyclododecanone Oximation. A cyclododecanone stream is reacted with hydroxylamine sulfate in oximation reactors, where the cyclic ketone is converted to cyclododecanone oxime by condensation. This reaction takes place in a medium with hydrocumene as solvent, under agitation. Ammonia is added to the reactors for pH control. The mixture is fed to a settler, and the oil phase is sent to next step, where oxime is extracted with sulfuric acid from hydrocumene.
Oxime Rearrangement. The solution of a cyclododecanone oxime sulfate adduct in sulfuric acid is then fed to jacketed agitated reactors. Under low pH and elevated temperatures, the cyclododecanone oxime is converted to Laurolactam via a Beckmann rearrangement. The reaction product is washed and neutralized by caustic soda in the presence of hydrocumene, in order to favor the subsequent settling. The purpose is to remove both residual catalyst, salts and acid entrained in the organic phase. After three more distillation columns, which separate lights, hydrocumene and heavies, Laurolactam is obtained.

Laurolactam from Cyclododecane (Photonitrization Process)
This report concerns the production of Laurolactam from cyclododecane in the United States. This report reviews a photonitrozation process similar to the one owned by Arkema. Initially, cyclododecane is submitted to PNC with nitrosyl chloride. The oxime produced is then subjected to Beckmann rearrangement and laurolactam is formed.

Laurolactam from Cyclododecane (Oximation with Hydroxylamine)
This report presents the economics of Laurolactam production from cyclododecane in the United States. Initially, cyclododecane is oxidized to cyclododecanol. Subsequently, the cyclododecanol obtained is dehydrogenated to cyclododecanone. Then, the cyclododecanone is submitted to an oximation reaction with hydroxylamine. Finally, the cyclododecanone oxime produced is converted to laurolactam by Beckmann rearrangement.
