Complementary Technologies (Styrenics / Phenolics / Carbonates)

The following licensed technologies can bring added value by supplementing or upgrading by-products from the primary styrenics, phenolics and carbonates production processes:

Butadiene Extraction (BDE)

The BASF NMP-based butadiene extraction process, licensed by Lummus Technology since 1990, is the preferred technology for the production of high purity 1,3-butadiene from crude C4 cuts. The technology is successfully applied in 41 plants worldwide, with a total capacity exceeding four million tons per year.

Paraxylene

Lummus Technology is the exclusive worldwide licensor of BP’s paraxylene technology, a unique process employing single stage crystallization for paraxylene (pX) recovery.

Pygas Hydrotreating (DPG I & II)

Lummus Technology's DPG™ I & II are the most widely-used pyrolysis gasoline hydrogenation technologies, with more than 50 units in operation or under design.

Pyrolysis/Steam Cracking

Lummus Technology’s proprietary ethylene steam cracking process is the most widely-applied process for the production of polymer grade ethylene, polymer grade propylene and butadiene. The process is noted for its performance, including high product yield and energy-efficiency, low investment cost and operating reliability.

PYROTOL® / DETOL® / LITOL®

Our dealkylation technologies (DETOL®, LITOL® and PYROTOL®) produce high purity benzene from any aromatics-rich feedstock. The yield of benzene from the higher homologs is nearly stoichiometric.

Modular PSA Recovery Plants

Lummus Technology’s long-standing capabilities in modular fabrication and hydrogen purification uniquely prepare us to offer turnkey gas recovery plants, even at small flow rates.
