TRANSFER • UNLOADING • CIRCULATION
Chemical processing
Move process chemicals between storage, mixing and production with a configuration selected for the complete fluid path. DFIN reviews each chemical duty against the actual concentration, temperature and operating conditions.
Common transfer duties
- Tank and IBC unloading
- Batch charging and vessel transfer
- Process recirculation
Selection priorities
Specify every chemical in the stream, including cleaning fluids. Check the body, diaphragm, balls, seats and seals together. For solvents, include the area classification, grounding and containment requirements.
