Abstract
A heat sensitive liquid is vaporized with minimum degradation by introducing it via an atomizer into an enclosed space together with a heated gas under pressure, and so that the gas circulates past heaters which are screened from the atomizer. Useful for vaporizing adipic acid into ammonia gas.
Claims3
A process for the vapourisation of a heat-sensitive liquid which comprises introducing into an enclosed space
- a. the liquid in fine droplet form through an atomising means, and
- b. a heated gas at a pressure greater than that in the enclosed space so that the gas circulates and recirculates in the enclosed space past heating means and is further heated, screening the said heating means from the said atomising means and vapourizing the liquid droplets in the part of the enclosed space screened from the heating means by the heated inlet gas and the further heated recirculating gas and removing the vapour from the enclosed space.
