Ethylene

Lummus Technology, a leader in ethylene technology, provides innovations proven in more than 120 ethylene plants around the world, accounting for about 40 percent of the world's ethylene capacity. We have successfully completed more grassroots, revamp and expansion projects than any competing technology licensor.

Ethylene plants using Lummus technology have a record of short, trouble-free start-ups; high reliability; long run lengths; and high on-stream factors. These advantages minimize start-up costs, maximize production, ensure high profitability, and achieve short payout time. Key to the success of the Lummus ethylene process is the SRT® (Short Residence Time) pyrolysis furnace.

Propylene

Lummus offers two on-purpose routes to propylene: Olefins Conversion Technology (OCT) for olefins metathesis and CATOFIN® propane dehydrogenation.

. . . via Metathesis of Butenes and Ethylene
With the OCT process, lower-value butylenes from ethylene plants and refineries are reacted with ethylene to produce propylene. These plants represent the lowest capital route for propylene production, with typical payouts of less than one year. The ultra-high purity propylene product produced by OCT exceeds polymer grade specifications and offers potential operating cost savings in downstream polypropylene plants.

. . . via Propane Dehydrogenation
The CATOFIN propane dehydrogenation process is a commercially proven fixed bed process for the production of propylene from propane. Utilizing recently enhanced catalyst technology, the CATOFIN process achieves the highest selectivity and conversion available for propane dehydrogenation.

Polypropylene

For the manufacture of polypropylene, Lummus Technology offers a complete package of process technologies, which includes the on-purpose production of propylene via CATOFIN propane dehydrogenation or Olefins Conversion Technology (OCT), and propylene polymerization via the Novolen® gas-phase polypropylene process.
