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 Gas Recovery
Building on a track record of over 100 Pressure Swing Adsorption (PSA) units since 1969, Lummus Technology is your full-range supplier of adsorption-based gas separation plants for hydrogen, helium and other high-value gases.
