Ethylene

Lummus Technology's proprietary ethylene process is the most widely applied process for the production of polymer-grade ethylene and propylene. The process is noted for its performance, including product yield and energy efficiency; low investment cost; and operating reliability. Plant owners have selected this technology for more than 200 projects, accounting for about 40% of worldwide ethylene capacity. Lummus Technology’s experience encompasses plants designed for ethylene capacities up to 1,350,000 MTA, and feedstocks from ethane through gasoils.

The high capacity SRT® pyrolysis furnace module is designed for short residence time and low pressure drop. The latest-generation SRT VII cracking coil provides maximum performance for all feedstocks and results in an easy-to-operate and robust mechanical design. The patented, close-coupled, single stage Quick Quencher transfer line exchanger (TLE) offers significant operating and cost advantages over competing designs.

The new, energy-efficient olefins recovery system minimizes capital investment by reducing the number of compressor casings by 40% and eliminating up to 25% of the equipment pieces used in a conventional system. Its key features are a low pressure chilling train that operates at less than half the operating pressure of a conventional flow scheme, and the tertiary refrigeration system that produces refrigeration from 40°C to - 140°C in a single refrigeration system. The lower piece count also reduces maintenance costs and improves reliability.

The CDHydro® process, which combines reaction and distillation in a single vessel, is utilized for separate C3 and C4 acetylene/diene hydrogenation. The combined acetylene/diene hydrogenation of the C2 through C5 fraction can be accomplished using Front End CDHydro, which has the added benefit of removing up to 35% of the pyrolysis hydrogen by chemical reaction instead of by cryogenic separation, thereby reducing energy consumption.

Lummus Technology's design approach emphasizes reliability, ease of operation, and broad feed flexibility at competitive costs. All plants meet designed capacity and exceed guaranteed performance. Average onstream time is above 98%, except in turnaround years where it is above 96%.
