Sulphuric Acid Plants:
Sulphuric Acid is reckoned among the most basic substances of chemical technology. Sulphuric acid is produced by thermal dissociation of waste acids, by suitable reconditioning of Sulphur containing waste gases or by use of Sulphur containing minerals, NIRMALA pumps are used for diluted, concentrated acids & for SO, 2 S0 scrubber applications.
Chlor-Alkali Plants:
Chlor-Alkali electrolysis is one of the most important processes in the chemical industry and provides the basic, chlorine, caustic soda and hydrogen. NIRMALA pumps are successfully used for Brine, Sulphuric Acid, Sodium Hypochlorite and Caustic Soda applications.
Chemicals and Fine Chemicals Processing:
Nowadays fine chemicals are increasingly gaining importance. This sector of the chemical industry comprises the pharmaceutical, biochemistry, biotechnology and many other chemical processing industries. NIRMALA pumps fitted with the latest shaft sealing technologies have surpassed all customer expectations in handling. Volatile Hazardous Air Pollutants.
Gas Scrubbers:
Gas scrubbers are designed for applications requiring the removal of various types of contaminants from gas streams. Typical applications for contaminant removal include noxious or toxic fumes from chemical processes. NIRMALA pumps have been recommended extensively for fiberglass re-in forced gas scrubbers. Particulate removal from gas streams is accomplished with the use of venturi scrubbers were NIRMALA pumps have proven track record.
Waste Water Treatment:
Effluent of chemical processing plants treated with caustic thus neutralizing the effluent. Effluent treatment facilities have ion exchange resins to remove ions from aqueous solutions. Hydrochloric acid is used to rinse the captions from the resin s thus producing dematerialized water. NIRMALA pumps have become standard equipment for acid, caustic & DM water applications amongst water treatment industry.
