This report describes the economics of an industrial process for propylene production via propane dehydrogenation (similar to CB&I Lummus process, known as CATOFIN). The economic analysis, based upon up-to-date data (2014/15), refers to a commercial-scale plant located on the US Gulf Coast, with a nominal capacity of 590 thousand metric tons of Polymer Grade Propylene per year.
It presents accurate economic estimates, including breakdowns for capital and operating costs, through easy-to-understand tables and charts. It is also included within the report a rich process description, comprising flow digrams and consumption coefficients for raw materials and utilities.
Propane dehydrogenation is one of the on-purpose propylene production processes that have become of great interest to the petrochemical marketplace, after propylene output as a by-product of naphtha-fed steam crackers decreased due to a shift to ethane-fed steam crackers that produce lower rates of propylene by-product. This is also the case of metathesis, and methanol-to-olefins/methanol-to-propylene (MTO/MTP) processes.
In this process, the propane dehydrogenation reaction takes place in fixed-bed reactors containing a chromium-based catalyst. The process uses a cyclic reactor operation with a controlled sequence of reaction and catalyst bed regeneration steps. Polymer grade propylene is obtained after compression, cooling, and distillation, which consists of a deethanizer and a propylene-propane splitter.

Keywords: Lummus Catofin, Clariant, Sud-Chemie, Propene, PG Propylene, Catofin Dehydrogenation.

Intratec's Technology Economics Reports
Technology Economics Reports are a family of reports, where each report is an up-to-date picture of an industrial process, detailing capital and operating costs of an industrial plant installed on a specific location (typically US). More specifically, each Technology Economics Report presents:
- Total Fixed Investment broken down by direct costs (per discipline), indirect costs and project contingency
- Working Capital and Initial Expenses
- Total Operating Costs broken down by Raw Materials costs, Utilities Costs and Fixed Costs
- Process Raw Materials Consumptions
- Process Flow Diagrams (PFD) and Main Equipment List
- Detailed Production Process Description
See a free sample of Technology Economics Report, examining another industrial process, and quickly realize why it is a great tool for understanding industrial processes costs.
For clients needing to perform customized assessments of industrial process economics, Intratec offers Economics Breakdown Apps. These apps are user-friendly desktop software applications, which may be used as delivered or customized to user’s specific needs, conditions and assumptions - in other words, users can see how capital investment and operating costs are affected by changes in inputs such as plant capacity, country location, products and raw materials prices.
