Introduction
During storage in tank farm, methyl ester final product quality could be negatively affected by the presence of some contaminants, already contained in the raw material fed to biodiesel plant. These components, identified mainly to be sterol glucosides, causes precipitation problems (e.g., accumulation in downstream equipment of production line, filter plugging in diesel engine) when stored for a certain time at ambient temperature.
Advantages
The Desmet Methyl Ester Cold Clarification Unit is designed to reduce the biodiesel Total Contamination in order to meet standard specification requirement (except of cold test CFPP and other parameters depending on feedstock and not influenced by transesterification process).
This technology allows removing the haze and decreasing contaminant quantity without using washing water for centrifugal separation minimizing the waste water effluents.
