The chlorine waste gas produced as a byproduct in the chlor-alkali industry is highly corrosive and toxic. If not effectively treated, it poses serious risks to the ecological environment and human health.Currently, most chlor-alkali chemical enterprises use the caustic soda absorption method to tre...
The Chlor-Alkali Membrane Cell industry really plays a crucial role in worldwide chemical production—it's kinda hard to overstate its importance. Back in 2022, this sector churned out about 94 million tons of chlor-alkali products, which is pretty impressive. One thing that’s gained a lo...
As a basic chemical industry producing chlorine (Cl2) and caustic soda (NaOH), the value of hydrogen produced as a byproduct of the chlor-alkali industry is increasingly recognized. Compared to dedicated water electrolysis for hydrogen production, chlor-alkali byproduct hydrogen is lower in cost, bu...
1. Core Process Overview
The core of the electrolysis process (chlor-alkali) is an electrochemical reaction driven by direct current (DC) (an endothermic reaction). Its core raw material is an aqueous solution of sodium chloride (NaCl). Under the action of DC current, it produces three core p...
