Many production, transformation and packaging processes generate : toxic gases, droplets of all sizes, corrosive, toxic and plugging dusts.
production, storage and packaging of basic chemical compounds
fluidized beds, dryers and coolers used in the production of fertilizers, sugars, lucern and urea
degassing of reactors in fine chemistry and pharmacy
burning liquids in the chemical an pharmaceutical industry
metallurgy and iron and steel industries
treatment of SO2
lime kilns, paper waste
degreasing and chroming baths, preparation and metallizing surfaces
For all these applications WATERLEAU France analyses the operating parameters and recommends the proper processes while fulfilling all legal obligations.
ESOLAV processes using vertical and horizontal scrubbers & absorption of chemical pollutants like :
bases : NaOH, NaClO3, ...
acids : HCl, HF, HCN, ...
sulfur-derivatives : SO2, SO3, H2S, ...
nitrogen-derivatives : NH3, NO2, RNH2, ...
toxic gases : Cl2, BF3, ...
VOC's : ethylenoxide, alcohols, ...
ESOSEP processes for collecting droplets (e.g. H2CrO4, H2SO4, HNO3) with a diameter up to 0,3 µm.
WATERLEAU France has standardized its ESOLAV and ESOSEP units in order to treat flows from 1.000 to 200.000 m3/h. These units can be made in different types of material (PVC, PPH, PVDF, SVR, Inox, ...) according to the requested fabrication quality. This standardization allows WATERLEAU France to propose the solution best adapted to the cleint's requirements.
Air pollution regulations are requiring refineries, cement and lime kilns, power plants and chemical manufacturers to remove acid gases, such as CO2 and particulates from flue gas before releasing it to the atmosphere.
Our DYNAWAVE® scrubber is the perfect solution for particulate removal, hot gas quenching and acid gas absorption such as SO2, HCl and HF.
Nearly all wet gas scrubbers work in the same way:
1. the acid gases are absorbed into the
2. the acid gases react with the reagent,
forming reaction by-products, which must be
removed from the clean gas
All scrubbers must have a method for removing the water droplets from the gas before they leave the scrubber
In many conventional scrubbers these three different functions occur in three different areas of the scrubber: The DYNAWAVE® is different from conventional scrubbers in that it uniquely handles all three these functions in the same zone of the scrubber, known as the "froth zone". This straightforward approach reduces both capital and operating costs. Most importantly, this approach allows minimal equipment inside the vessel, making DYNAWAVE® an extremely reliable scrubber.
