HYDROCHLORINATION HEATER AND RELATED METHODS THEREFOR

摘要

The systems and method of the invention involve hydrochlorination by providing feed streams with suitable reaction conditions through reactant stream conditioning systems and components. The conditioning systems facilitate vaporization of silicon tetrachloride in gaseous hydrogen to produce a reactant stream comprising hydrogen that is saturated with silicon tetrachloride. Saturation can be effected without the use of superheated steam or hot oil by utilizing saturated steam that is less than about 15 bar. The saturated reactant stream can be further heated to reaction conditions that effect conversion to trichlorosilane.
