BTX Production from Ethane

In this study, the process reviewed is a typical aromatization process producing a mixture of Benzene, Toluene and Xylenes (BTX) from ethane. In this analysis, ethane is first dehydrogenated to ethylene, which is oligomerized. The oligomers then cyclize to form naphthenes. They are finally dehydrogenated, yielding aromatics. The economic assessment assumes a plant located in the United States.

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

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