Abstract
Process for reacting acid and base by use of a spray mixing nozzle having a central pressurized gas channel, at least two surrounding annular channels for acid and base and an outer annular channel for pressurized gas. The pressurized gas forcefully unites the acid and base into a spray at the nozzle outlet, and the acid and base react in the spray.
Claims5
A process for reacting an acid and a base, which comprises:
- passing pressurized gas through a central channel of a spray mixing nozzle to the outlet orifice of the nozzle;
- passing to the outlet orifice of the nozzle liquid acid through one and liquid base through a second of at least two annular channels which surround the central channel;
- and
- passing pressurized gas through an outer annular channel which surrounds the at least two annular channels to the outlet orifice of the nozzle, said pressurized gas from the central channel and the outer annular channel forcefully mixing the acid and base from the at least two annular channels in a spray at the nozzle outlet at a throughput capacity in excess of 150 to 200 liters per hour whereby the acid and base react in said spray to produce a salt.
