Corrosion Problems with Process Conversion in the Chlor-Alkali Industry

Conversion from Mercury to Alternative Technology in the Chlor-Alkali Industry

Chlor-alkali industry production scheduling algorithm research based on adaptive weight PSO

First of all, in view of the process industry production scheduling system, the mathematical model of the process industry production scheduling was established. Secondly, the shortest maximum completion time was taken as the goal, process industrial production scheduling algorithms based on particle swarm optimization (PSO) was proposed. Finally, the specific production tasks of propylene oxid...

Removal of Mercury from chlor-alkali Industry Wastewater using Acetobacter xylinum Cellulose

In this study, the removal of mercury ions by cellulose of Acetobacter xylinum was investigated in the synthetic and chlor-alkali wastewater. Biofilms of Acetobacter xylinum were grown in laboratory column bioreactors. The biofilms were continuously treated with sterile synthetic model wastewater or nonsterile, neutralized chloralkali wastewater.The extent of adsorption was studied as function ...

LABORATORY INVESTIGATION OF PCDD/Fs AND DIOXIN-LIKE COMPOUNDS FORMATION DURING CHLOR-ALKALI PROCESS

Abstract We examined polychlorinated dibenzo-p-dioxin, polychlorinated dibenzofuran (PCDD/Fs) and dioxin-like compounds formation during brine electrolysis with pitch used as the binding agent of graphite electrode. Graphite electrode was used in the past as an industrial process of chlorine production. The level of PCDFs was up to 1,800,000pg/L (28,000pg-TEQ/L) in brine electrolysis with pitch...
