SELA developed and patented in 1984 a new process in which vapor can be recovered and soap dust can be reduced significantly.

In conventional soap drying plants the water content of the neat soap is reduced from 30% to 10% or 20% by evaporation. The vapor generated in the heat exchangers was not used in the past.

The new vapor extraction system integrated between the heat exchangers and the vacuum chamber extracts the vapor and thus gives significant commercial and operational benefits to the customer. It can be implemented in any existing soap drying plant.

The permanent development of this process nowadays makes possible to use the extracted vapor as motive steam for the possibly required steam ejector so that there will be considerable savings of motive steam and cooling water.

In accordance with the design data, per ton of dried soap approx. 150 kgs/hr of steam and up to 19 m3/hr of cooling water can be saved. An individual adaptation of the plant to the requirements of the customer guarantees an optimal operating result.
