Abstract
Halogen hydrates, such as chlorine hydrate, are made by directing finely divided droplets of an aqueous medium onto a refrigerated surface which is at a temperature below that at which the hydrate forms, while also contacting said surface and said aqueous medium with the halogen to be converted to halogen hydrate. Apparatuses and methods are described. In a preferred embodiment of the invention the atomized droplets of aqueous medium, in very finely divided droplet form are directed onto a moving corrosion resistant metal surface from which the hydrate is subsequently removed. In another embodiment of the invention chlorine gas is utilized to atomize the aqueous medium and the mixture of chlorine and aqueous droplets is directed onto a forming surface.
Claims6
A method of manufacturing a halogen hydrate which comprises the steps of:
- maintaining a forming surface at a temperature sufficient to form halogen hydrate from a halogen and an aqueous medium, said surface being maintained at a temperature from about -20.degree. to about -5.degree. C;
- introducing under pressure onto said forming surface:
- a halogen and
- an aqueous medium consisting of a plurality of atomized liquid droplets each having a diameter between 1 millimicron and about 10 microns, the temperature of said aqueous medium being maintained above the freezing point of said medium and below 5.degree. C.
- the pressure of said aqueous medium being greater than the pressure of said halogen, and said halogen and said aqueous medium being introduced in amounts such that the stoichoimetric ratio of halogen to water in the aqueous medium is at least about 6 moles of water per mole of halogen;
- contacting said halogen and said aqueous medium on said forming surface such that the droplets of said medium are surrounded by said halogen to form halogen hydrate with a small percentage of some halogen becoming dissolved;
- and
- removing said halogen hydrate from said forming surface.
