Как работи

Physical refining process or chemical refining process

Alfa Laval biofuel pretreatment systems include both physical refining processes and chemical refining processes. For HVO the preferred process is physical refining, involving special degumming and/or enzymatic degumming, adsorption, and deacidification (if required). The chemical refining process is mainly used in pretreatment of traditional biodiesel (fatty acid methyl esters), where Alfa Laval also has a vast experience.

Removal of phosphorous and trace metals

To remove phosphorous and trace metals, the fats and oils (tallow, soy, rapeseed, distillers, corn oil, etc.) as well as recycled animal fat and used cooking oils undergo degumming with acid treatment (citric or phosphoric acid), and washing and adsorption using bleaching clays or similar with Alfa Laval high speed separators and plate heat exchangers.

Chloride removal

Chlorides, if present, are removed at the front-end of the process by water washing and onward processing in Alfa Laval high speed separators and plate heat exchangers.

Polyethylene removal

Polyethylene, if present such as in some tallow qualities, can be removed by crystallization and filtration.

Fatty acid removal

In some cases, the fatty acid content must be limited to eliminate the risk of corrosion due to metallurgy in the HVO section. This can be achieved by co-processing a blend of feedstocks, if needed, as well by steam stripping the oil under vacuum conditions using an Alfa Laval Aalborg High Pressure Natural Circulation boiler, welded and gasketed plate heat exchangers and an Alfa Laval stripping column.
