Sodium Lauryl Ether Sulfate Production
Sodium Lauryl Ether Sulfate Operating Costs & Plant Construction Costs
This report presents the economics of Sodium Lauryl Ether Sulfate (SLES) production from chlorosulfonic acid, lauryl ethoxylate, and sodium hydroxide in the United States. In the process examined, lauryl ethoxylate reacts with chlorosulfonic acid (sulfation). The product is neutralized with sodium hydroxide, producing the surfactant.
The report provides a comprehensive study of Sodium Lauryl Ether Sulfate production and related Sodium Lauryl Ether Sulfate production cost, covering three key aspects: a complete description of the Sodium Lauryl Ether Sulfate production process examined; an in-depth analysis of the related Sodium Lauryl Ether Sulfate plant capital cost (Capex); and an evaluation of the respective Sodium Lauryl Ether Sulfate plant operating costs (Opex).
The Sodium Lauryl Ether Sulfate 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 Sodium Lauryl Ether Sulfate 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 Sodium Lauryl Ether Sulfate 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) Sulfation; (2) Neutralization; (3) Scrubbing; and (4) Packing.
Sulfation. Initially, the lauryl ethoxylate is batch sulfated by cholorosulfonic acid. Both reagents are fed to a glass-lined stirred, jacketed reactor, with the acid being gradually added to the reaction. The sulfation is carried out at 25 - 30°C under vacuum, over about a period of 2.5 hours. The gaseous HCl by-product is led off the sulfation product, and directed to a scrubber downstream. The sulfation product is fed to the neutralization.
Neutralization. The sulfation product is fed to a neutralization vessel, where it is contacted with a 50 wt% caustic soda solution along with process water for adjusting its active component. The neutralization reaction is carried out at a temperature below 45 °C, generating a 70 wt% sodium lauryl ether sulfate further routed to packaging.
Scrubbing. The HCl evolved during the sulfation is fed to a scrubber, where it is absorbed in process water generating a 33 wt% hydrochloric acid solution by-product.
Packing. SLES is packed in drums and then sent to warehouses at the facility’s outside battery limits (OSBL) to be stored.
