MEK DEWAXING

MEK (Methyl Ethyl Ketone) dewaxing is a complex process process for physically removing wax, by crystallisation and (rotary vacuum) filtration. A rotary vacuum filter consists of a hollow drum that sits in a vat, which is covered by a sealed hood and is maintained at a slightly positive pressure. The drum is rotated allowing the wax cake to be washed with chilled solvent (to reduce the amount of oil trapped in the wax cake) before it is discharged, via a scraper blade, to the wax boot.
Due to our long experience with Pressure Vessel, we are also able to manufacture PDU (Propane Dewaxing Unit) which is more suitable in processing Bright Stocks.
