Chemical Engineering Partners (CEP) licenses state of the art re-refining technology by providing its basic engineering package and optional detailed engineering services to clients world-wide. Some of the project locations include:
LWART located in Lençóis Paulista, Brazil
CEP provided basic engineering and hydrotreating technology for the LWART re-refinery in Lençóis Paulista, Brazil. LWART’s total site capacity is 330,000 metric tons/year. This plant design utilized the CEP Process including Wiped Film Evaporation and Hydrotreating Technology. LWART successfully started production in October, 2012. LWART is the biggest and only API Group II base oil producer in South America. In 2023, LWART announced an expansion to build a second plant with a capacity of 100,000 metric tons per year. The second plant began commercial operation in September 2026.
Universal Lubricants located in Wichita, Kansas, USA
CEP provided basic engineering, hydrotreating technology and detailed design for this 40,000 metric tons/year (12 million gallons per year) re-refinery built in Wichita, Kansas. This plant design utilized the CEP Process including Wiped Film Evaporation and Hydrotreating Technology. Modular fabrication was used to reduce capital costs. This plant successfully started up in October, 2009. The Wichita refinery was acquired by Safety-Kleen, a subsidiary of Clean Harbors, in 2016.
L&T Recoil facility located in Hamina, Finland
CEP provided basic engineering and re-refining technology for this 60,000 metric tons/year plant. The CEP Process was used including Wiped Film Evaporator and Hydrotreating for this state of the art plant in Hamina, Finland. This plant started up in August, 2009. In 2024 TotalEnergies acquired this plant.
Heartland Petroleum facility located in Columbus, Ohio, USA
CEP provided basic engineering and hydrotreating technology for this plant built in Columbus, Ohio. The Heartland plant is an example of how the CEP hydrotreating process can be integrated into a new or existing non-hydrotreating plant. This plant successfully started in April, 2009. GFL acquired the Heartland refinery and associated used-oil collection business from Vertex Energy on February 1, 2023.
Evergreen Oil Inc. Line 2 located in Newark, California, USA
After 24 years of operation of Line 1, Evergreen Oil expanded their capacity, by adding a second line at the same location. Line 2 was designed using all the advancements and improvements made to Line 1. Line 2 successfully started operation in 2010.
Olein Recovery Corporation - Puerto Rico Re-Refining Facility
CEP provided basic engineering, hydrotreating technology, material supply and detailed design for this plant built by Olein in Puerto Rico. This plant started up successfully in 2006.
PAZ facility located in the Middle East
CEP has licensed the Thin Film Evaporation technology and engineering services to its client to produce an effective and profitable re-refining site in the Middle East.
Southern Oil facility located in Wagga Wagga, Australia
CEP has provided its Thin-Film Evaporation technology to Southern Oil in Wagga Wagga, NSW, Australia. This plant has been in operation since 2001.
WGI facility located in Bekasi, Indonesia.
Chemical Engineering Partners has designed and licensed CEP’s Thin Film Evaporation and Hydrotreating technology to WGI in Indonesia who has been successfully operating since 1995.
Evergreen Oil Inc. Line 1 located in Newark, California, USA
CEP originated as a sister company to Evergreen Oil Inc. CEP engineers provided engineering support to this plant and helped optimize operation through improved reliability and increased yields. This ground-breaking re-refinery began operation in 1986 and utilized both the CEP Thin Film Evaporation and Hydrotreating processes.
