Pollution control equipment are highly efficient in providing pollution control solutions for different industrial requirements. Our expertise pollution control equipments is continually called upon in wide range of geographical environments. • Gas Absorption Plants • Fume Extraction System For Pickling Plants • Fume Extraction System For Pharmaceutical Plants • Fume Extraction System For Pesticide and Petrochemical Plants • Sulphur dioxide Absorbers For Sulphuric Acid Plants

We manufacture and supply gas absorption plants for emission control of any toxic gas like
• NH3
• HCl
• HF
• NOx
• SO2
• Cl2
• Hbr
• Br2
• H2S
• HCN
• HCHO, etc.

These pollution control systems are manufactured in according to set industrial pollution control parameters. All our products are quality tested & we ensure to deliver certified air pollution control system.

The two types of Fume Extraction System are as follows -

(1) Continuous pickling lines of the closed type for strips and wires.
(2) Batch pickling lines of the open type for wire coils, straight tube bundles, automobile bodies (surface pretreatment prior to painting) etc.

Induced draft type fume extraction systems are adopted for the former and push-pull type systems are used for the latter. The surface treatment solutions could be hydrochloric acid, sulfuric acid, hydrofluoric acid, nitric acid, chromic acid or any other at various concentrations and temperatures. The design of the system is aimed at protection of the operating personnel on the one side and protection of the environment by controlling emissions. Temperature, concentration and toxicity and partial pressures of the vapors are considerations in system design. Our service covers from conceptualization to design, selection of appropriate materials of construction, manufacture, specification and procurement of purchased items such as pumps, motors, instrumentation and control etc., supply, erection, commissioning and handing over with guarantees for quality and integrity of the supplies and performance of the system conforming to specified parameters.

Several toxic chemicals are used in the manufacturing of pharma products. Also they generate several highly toxic gases such as NH3, HCl, HF, NOx, SO2, Cl2, HBr, Br2, H2S, HCN, HCHO and other organic and inorganic gases. The emissions from the plant have also to be controlled. As the gases generated are of different types the solutions to be used for absorbing them will also be different. As it would be expensive to use many absorption systems, the reactors are grouped into two or more groups for the purpose of providing fume extraction systems. The systems cover everything from retractable fume hoods near reactors to protect personnel to final absorbers and stacks. Our engineers give total service from consultancy to commissioning including supply and erection.

We also undertake turnkey contracts for petrochemical & pesticide plants for the extraction and absorption of toxic gases in the case of any chemical industry, pesticide and petrochemical industries in particular.

We have developed gas absorption systems, which do not require heat exchangers. Heat exchangers with expensive materials of construction are used to cool the acid. Absorption of HCl or HBr to produce concentrated acid is accompanied by generation of large amount of heat. This results in saving in capital costs.

We design and manufacture special tray-type absorbers for acid regeneration plants. The spent acid containing chlorides of iron is oxidized in a fluidized bed reactor to produce iron oxide and HCl vapours. Whereas iron oxide is a useful bye-product, the HCl is absorbed in stoichiometric quantities of water to obtain 17 to 20% hydrochloric acid and reused for pickling. Finally the gases are passed through columns to limit emissions within pollution control limits.

The reaction is exothermic and wet chlorine is highly corrosive requiring coolers and special materials of construction. Often sodium hypochlorite is produced in caustic chlorine plants by the absorption of chlorine gas in sodium hydroxide. We can manufacture and supply these plants on turn-key basis.

The rotating speed of the agitator and natural frequency of the system as a whole have to be taken into account for the design to avoid failures. Vessels with agitation require special considerations in design. Agitation produces dynamic loading.

• Mixing / Reaction Vessels With Agitator Assembly
• Mixer / Settlers

The mixers will have special type of variable speed agitators for transfer of liquids. Mixer-settlers are used for liquid-liquid solvent extraction for purposes such as separation of nuclear chemicals and other metallurgical separations.
