SELECTION
Validate with your feed
Compatibility and bench validation are required for the actual solvent, solute, temperature, pressure and concentration.
Testing & scale-upOPERATION
Operating guidance
Confirm solvent compatibility
Validate special solvents, additives and elevated pressure, temperature or concentration before use.
Ramp pressure and temperature smoothly
Avoid sudden pressure or temperature shock during operation and cleaning.
Preserve during shutdown
Keep wet elements immersed in a suitable preservative and sealed during extended shutdown.
