Deodorization of edible oil is done by a stripping process through several steps of steam condensation and vacuum extraction including high consumption of energy and water. For this oil refining plant, the deodorization process amounts to 78% of the total energy consumption and 38% of total water consumption.
Introducing the most recent techniques using dry ice condensing system shall provide a simple, environmentally friendly, cost effective and low temperature way to replace the process vapor used for edible oil deodorization.
