  2. 6. Mathematical modelling and experimental simulation of chlorate and chlor-alkali cells

    Author : Philip Byrne; KTH; []
    Keywords : chlorate; chlor-alkali; current density distribution; current distribution; potential distribution; hydrodynamic behaviour; electrolysis; bubble-evolution;

    Abstract : The production of chlorate, chlorine and sodium hydroxiderelies heavily on electrical energy, so that savings in thisarea are always a pertinent issue. This can be brought aboutthrough increased mass transfer of reacting species to therespective electrodes, and through increased catalytic activityand uniformity of current density distribution at theseelectrodes.

  4. 7. Influence of the electrolyte on the electrode reactions in the chlorate process

    Author : Linda Nylén; Göran Lindbergh; Ann Cornell; Mårten Behm; Geoeff H Kelsall; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chlorate; chloride oxidation; critical anode potential; chromate; DSA; hydrogen evolution; iron; mass transport; oxygen evolution; REM; RDE; steel; Electrochemistry; Elektrokemi;

    Abstract : The chlorate process is very energy intensive and a major part of the production costs are for electrical energy. Since the electricity prices are constantly increasing and may also vary periodically, the chlorate plants may be forced to adjust their production rate to the price at each moment in order to minimise their costs.

  5. 8. Electron transport in microbial chlorate respiration

    Author : Anna Smedja Bäcklund; Thomas Nilsson; Åke Strid; Karlstads universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; c cytochromes; chlorate reduction; electron transport; c cytokromer; kloratreduktion; elektrontransport; Biochemistry; Biokemi; Kemi; Chemistry;

    Abstract : Several bacterial species are capable to use perchlorate and/or chlorate as an alternative electron acceptor in absence of oxygen. Microbial respiration of oxochlorates is important for biotreatment of effluent from industries where oxochlorates are produced or handled. READ MORE

  6. 9. Oxygen formation in the chlorate process and preparation and deactivation of ozone selective anodes

    Author : Staffan Sandin; Ann M. Cornell; Paul Christensen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATO; EOP; ozone; electrode preparation; elec- trode deactivation; hypochlorite; chlorate; oxygen; chromium VI ; sodium dichromate; electrocatalysis; catalysis; Chemical Engineering; Kemiteknik;

    Abstract : This thesis presents experimental studies concerning two differ-ent electrolytic processes. One part deals with the electrochemicalformation of ozone and focuses on the preparation and deactiva-tion of a highly ozone-selective metal oxide anode (NATO - nickeland antimony doped tin oxide).
