Here are the main vessel types in our grease plant projects.
On smaller plants, we normally use a single stage process, based on kettle to do both the saponification and the finishing.
For larger plants we normally use a two stage process. The first stage is saponifying in an autoclave or saponification kettle. The second stages is finishing in kettles where the dilution base oils and additives are introduced.
Our process vessels are built by UK manufacturers who work as our subcontractors to our designs. If the circumstances demand we can outsource from other countries, depending up the quality and reliability of the company concerned.
