Patent number: 9743670Abstract: The present invention relates to a method of preparing chlorine dioxide (ClO2) from hydrochloric acid (HCl) and sodium chlorite (NaClO2) in the presence of water (H2O). The invention has for its object to further develop the method such that it is more economical to install and operate. The object is achieved when the hydrochloric acid is used in aqueous solution at a concentration of 27 to 33 wt %, the sodium chlorite is used in aqueous solution at a concentration of 22 to 27 wt % and the molar ratio of hydrochloric acid used to sodium chlorite used is between 2.14 and 4.2.Type: GrantFiled: October 11, 2012Date of Patent: August 29, 2017Assignee: Infracor GmbHInventors: Gerda Grund, Hartmut Rahtz, Hermann-Josef Korte

Patent number: 9206063Abstract: The invention relates to an apparatus (1) for feeding chlorine dioxide to water, comprising a first feed pipe (5a) for feeding in a first reaction component, comprising a second feed pipe (5b) for feeding in a second reaction component, comprising a mixing tube (2) for mixing and reacting the two reaction components to chlorine dioxide, at one end of which the two feed pipes (5a, 5b) join and at the other end of which is arranged a suction chamber (4) into which feed water to be enriched with chlorine dioxide can be sprayed by means of a nozzle (12), and comprising an exit water pipe (13) leading downstream from the suction chamber (4). This object is further to develop such an apparatus so that it is simple and has a robust design and permits different chlorine dioxide syntheses based on two reaction components to be carried out without danger.Type: GrantFiled: February 17, 2011Date of Patent: December 8, 2015Assignee: Infracor GmbHInventor: Johannes Duve
