Singlet delta oxygen generator and process

摘要

A singlet delta oxygen generator 10 comprises a static or motionless mixer 12 having a gas inlet 14 through which chlorine gas reactant is introduced into the static mixer and a liquid inlet 16 through which the basic sodium hydroxide/hydrogen peroxide solution is introduced. As the reactants pass through static mixer 12, the gaseous products and liquid by-products are formed. The product stream passes through liquid/gas separator 26 wherein the liquid by-product stream is diverted to sump 28 and the gaseous product stream is conveyed to a low volume trap 30. The temperature of trap 30 is maintained at approximately -80 DEG C. so as to solidify and thereby remove any water or hydrogen peroxide vapor which might remain in the product stream. From the low volume trap 30, the product stream is then conveyed to chlorine trap 34 wherein any excess chlorine gas present in the system is retained.
