Propylene Production from Naphtha (Steam Cracking)

This report approaches the economics of producing Polymer Grade (PG) Propylene from light naphtha in Germany, using a typical low-severity steam cracking process (maximizing propylene to ethylene ratio). In addition to Propylene and ethylene, the process generates electricity, crude C4, pyrolysis gas and fuel oil.

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

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