Solvent Oil Dewaxing (SOD) filters have been specifically designed and constructed for the most efficient method of processing petroleum base oil lubricating stocks to produce wax-free oil and oil-free wax.
The filter consists of several major components:
- Vapor tight tank and hood
- Internal rotating drum
- Master control valve
- Cake washing assembly
- Wax deflector
- Wax discharge scroll
Many design improvements have been pioneered and introduced by FLSmidth Minerals.
- Valve end internal bearing design insures "vapor tight" unit while eliminating the need for stuffing boxes on the valve end.
- Drive end floating stuffing box arrangement in conjunction with a stainless steel bellow type seal, also insures "vapor tight" construction.
- Nylon grid drum deck construction results in improved hydraulic efficiency, increased cloth media life and reduced maintenance.
- Redesigned drum internal piping improves drum hydraulics and enhances drum structural integrity.
