How to remove crystalline salts from sodium hydrosulfide?
sodium hydrosulfide exports to multiple countries, with competitive prices and fast shipping. Click here for surprisesFurther Steps Include:
The concentrated NaHS Sodium hydrosulfide solution from the NaHS concentration tank is fed into a decanter centrifuge to separate crystalline salts and molten NaHS·H₂O.
The separated crystalline salts are sent to a dryer, where they are first dehydrated in the upper HEAting layer and then cooled in the lower cooling layer before being collected for use as a water treatment agent.
The molten NaHS·H₂O, after crystalline salt removal, is transferred to a vacuum-insulated holding tank and then pumped into a vacuum rake cooler for solidification into thin flakes.
The NaHS Sodium hydrosulfide flakes are discharged through a rotary valve and automatically packed.
Gaseous phases extracted from the vacuum holding tank and vacuum rake cooler are treated by an exhaust gas treatment system.
