Hello Jim, when using the acid esterification, you will have methyl esters, unreacted oil, sulphate ions, oxonium ions and - water. Proceeding to the base step you will create more methyl esters, potassium or sodium soaps, maybe a little unreacted oil or partially reacted oil, potassium or sodium sulphates and - even more water. This method works fine if the water content can be kept on a reasonable level. Please note that the higher the initial FFA level, the more water will be produced. With best regards Jan Jan Warnqvist AGERATEC AB
