With its DORR-OLIVER and EIMCO Dewaxers the Leader in Dewaxing Filter Technology
Wherever dewaxing filters are used, FLSmidth world-renowned technology has brought many benefits - superior recovery and quality of oil and wax, rigorous environmental protection, and maximum productivity. The know-how necessary to deliver a reliable product, tailor-made for the job, has resulted in considerable savings for the petrochemical industry over many years.
The majority of lube oil plants use MEK based solvent dewaxing technology and Dorr-Oliver Eimco has supplied hundreds of filters for the MEK process as well as hundreds more for other solvent dewaxing processes, based on DIME, propane, etc.
