Fume Extraction System for Pickling Plants
Steel pickling plants are mainly of two types viz. (1) Continuous pickling lines of the closed type for strips and wires and (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.
