Lummus Green Circle and Chevron Global to Offer Circular Solutions

HOUSTON – Green Circle of Lummus Technology and Chevron Lummus Global (CLG) announced the integration of several technologies from their portfolios for application in the circular economy. The partners will use a combination of Lummus New Hope Energy plastic pyrolysis technology, ISOCONVERSION technology from CLG and steam cracking technology from Lummus to provide operators with the ability to produce high volume steam cracker products from oil. of hydrotreated plastic pyrolysis from mixed waste.

“The combined solution offers major owners and operators the ability to authorize the entire plastics recycling process,” said Leon de Bruyn, president and CEO of Lummus Technology. “No other company can offer this type of integration on this scale and with proven technological solutions. The combination of these technologies is the innovation and collaboration necessary to make real contributions to the circular economy and the energy transition. . “

“We believe innovation is key to providing the solutions and technology needed to transition plastics to a circular model. We have advanced our ISOCONVERSION technology to now address the unique challenges encountered in plastic recycling, ”said Ujjal Mukherjee, Managing Director of CLG. “By integrating technologies into Green Circle, we can offer customers unique solutions that reduce costs and overall project complexity.

Lummus New Hope Energy plastics pyrolysis technology recycles end-of-life plastics into petrochemical raw materials. Through a robust thermal pyrolysis process, the technology produces a high quality pyrolysis oil that is proven, scalable and economical for operators wishing to replace or supplement petroleum-derived raw materials.

Lummus’ ethylene steam cracking technology produces polymer grade ethylene, polymer grade propylene and butadiene. The process is recognized for its performance, including high product yield and energy efficiency, low investment cost and reliability of operation.

CLG’s ISOCONVERSION technology uses advanced hydrotreatment technologies to transform biomass and pyrolysis oils from plastic waste into renewable fuels or petrochemical feedstocks.

A subsidiary of Lummus, Green Circle is a leader in the commercialization and development of revolutionary solutions to address the key pillars of the energy transition, including the recycling of end-of-life plastic waste, the production of sustainable bio-derived chemicals and decarbonization strategies for existing and new products. assets.
