The process relies upon excessive amounts of pressurized oxygen gas to both oxidize the solution and to increase the solution's evaporation rate. The oxidized liquid effluent from a reactor undergoes a series of flashing steps until a saturated solution is produced which readily crystallizes upon cooling.Field of SearchBy oxidationSubmerged fluid inlet Liquid phase high temperature and pressure (e.g., "wet air", etc.) Catalytic Catalytic And recirculating liquid Plural separating Including specified pressure change WITH HEATER OR HEAT EXCHANGER Vapor or gas removal RECIRCULATION Serially connected distinct treating or storage units WITH MEANS TO ADD TREATING MATERIAL Plural distinct separators Serially connected Diverse type With distinct reactor tank, trough or compartment Chemical holder in series with separator | |
