Abstract
Provided are methods and systems for the production of alkyl polyglucoside. The methods and systems provide for improved purification that results in reduced produce degradation.
Claims12
A method for removing at least one impurity from a stream comprising alkyl polyglucoside, said method comprising the steps of:
- (i) providing a first fluid stream comprising alkyl polyglucoside and at least one impurity;
- and
- (ii) passing the first fluid stream comprising alkyl polyglucoside and at least one impurity through a plate heat exchanger,
- wherein in step (ii) a second fluid stream is simultaneously passed through the plate heat exchanger, the second fluid stream being fluidly isolated from the first fluid stream, and thermal energy is transferred from the second fluid stream to the first fluid stream, thereby increasing the temperature of the first fluid stream to form a heated first fluid stream having a temperature above a boiling point of at least one impurity in the first fluid stream, such that the heated first fluid stream comprises a liquid phase comprising the alkyl polyglucoside and a gaseous phase comprising the at least one impurity and the gaseous phase is separated from the liquid phase.
