One of the top three largest producers of glycerin and fatty acid in India was able to reduce utility consumption by 20% and decrease their environmental impact, using Munters' mass transfer solutions.
The customer is one of the top three largest producers of glycerin and other integrated components of fatty acids in India.
The fatty acid distillation plant has been designed and installed to achieve the desired product purity and quality at a minimum cost and also to take care of variations in input feed composition.
After detailed study of entire fatty acid distillation plant and thorough hydraulic rating of existing tower internals, several problems were noted which were restricting the installed capacity:
Munters recommended changing random packing to structured packing, thus allowing better contact of liquid and vapor and ensuring low pressure drop. The tower internals were also re-designed to suit the modified packing. Further, the liquid distribution system was re-designed by modifying the existing pipe arm distributor and including a new liquid distributor to ensure efficient liquid distribution on the packed bed. Enough space was provided for good disengagement of vapor from liquid.
The column is now working satisfactorily with increased capacity by approx. 30-40% and reduced utility consumption by approx. 20%.
At the top of the columns, the client achieved removal of C6-C10 fatty acid impurities with the slippage of C12 fatty acid reduced to the extent of =< 1%. At the bottom of the columns, the client achieved desired product purity and slippage of C10 fatty acid impurities to the extent of >=1%.
