Linear Alkylbenzene Sulfonate Production from LAB and Sulfur

This report analyses the economics of Linear Alkylbenzene Sulfonate (LAS) production from linear alkylbenzene (LAB) and sulfur in the United States, via a conventional sulfonation process. In this process, elemental sulfur is burned, yielding sulfur dioxide, which is then oxidated with dry air to produce sulfur trioxide, the sulfonating agent. The primary product is the para-alkylbenzene sulfonic acid, which is further neutralized.

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

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