Chlorine Gas Filter

The filter represents a new approach to the removal of the nuisance causing impurities in chlorine gas . this filter has two chambers. The lower portion acts as a liquid trap for liquid impurities(reliquified gas /or foam droplets from the vaporizer). The sudden enlargement decreases the velocity, so that gas is unable to carry entrained droplets of liquid chlorine which is high in ferric chloride. The upper portion has a removable filter. The filter element is especially so that the ferric chloride “plates out” rapidly as it passes through the element. Therefore, the filter acts as both a filter and a condensate liquid trap.

Facts about impurities in chlorine gas
The principal impurity is FERRIC CHLORIDE. This is inherent in chlorine gas because it is packaged in a steel containers. The amount or ferric chloride that deposits out in a chlorine gas system is a function of the quantity of chlorine used. There is no convenient way of removing impurities from liquid chlorine. Impurities will always precipitate out of gas when it reliquifies.
