Chlorate Destruction Tank (Titanium Gr2)

Chlorate Destruction Tanks stand as pivotal elements within the intricate processes of Chlorate Destruction Systems in chlor-alkali plants. These tanks serve a crucial function in mitigating the challenges associated with sodium chlorate generation, ensuring the safe disposal and conversion of these compounds.

Functionality and Purpose: The primary objective of the Chlorate Destruction Tank is the controlled decomposition of sodium chlorate, a byproduct generated within chlor-alkali electrolysers. This process is facilitated by the reaction of sodium chlorate with hydrochloric acid, executed at an elevated temperature. The resulting chemical reaction yields chlorine, a key component in various industrial applications.

Design and Configuration: These tanks are meticulously designed as vertical pressure vessels for specific reasons. Firstly, their positioning above the anolyte tank enables the gravitational overflow of the processed substances from the Chlorate Destruction Tank into the anolyte tank. This gravitational flow is critical for the seamless continuation of the process. Secondly, the vertical orientation aids in in-situ mixing, employing a specialized jet mixer installed within the tank. This ensures efficient and thorough amalgamation of the reactive components.

Operational Considerations: Safety and structural integrity are paramount in the design of these tanks. They are engineered to withstand the maximum pressure exerted by chlorine and are equipped with venting mechanisms that channel excess pressure safely to the cellroom’s primary chlorine header. Heating the contents of the Chlorate Destruction Tank is achieved via a steam-heated plate heat exchanger, utilizing a pumped recirculating loop powered by the site’s low-pressure steam supply.

Sizing and Parameters: The sizing of these tanks adheres to stringent guidelines outlined in the design basis document. The dimensions are calculated to ensure an adequate residence time within the tank, vital for achieving the required level of chlorate destruction. The kinetics of the chemical reactions occurring at the specified operating temperature (90°C) are carefully considered in determining the optimal tank size.

Titanium Storage Tank

Using Gr2 titanium to manufacture the Chlorate Destruction Tank ensures excellent corrosion resistance and chemical stability when handling chlorides and chlorate compounds. Simultaneously, it ensures the structural strength and reliability of the equipment.

Excellent Corrosion Resistance: Gr2 titanium exhibits outstanding corrosion resistance, especially towards chloride mediums such as chlorine gas and chlorides. The handling of chloride compounds in the Chlorate Destruction Tank demands a material capable of withstanding intense corrosion, and Gr2 titanium maintains stability and prevents corrosion in such environments.

Chemical Stability: Gr2 titanium demonstrates good stability in various chemical environments and is less susceptible to chemical substance erosion. This makes it an ideal choice for handling diverse chemical substances, particularly in scenarios requiring resistance to high chlorine content or acidic mediums.

High Strength and Lightweight Properties: Gr2 titanium boasts good strength and rigidity while being relatively lightweight. This allows it to maintain structural integrity under pressure and loads, simultaneously reducing the overall weight of equipment, aiding in lowering transportation and installation costs.

Long-Term Stability and Durability: Due to its corrosion resistance and chemical stability, equipment made from Gr2 titanium typically has an extended lifespan. This implies reduced maintenance needs and fewer component replacements, consequently minimizing downtime and maintenance costs
