V-tex® Scrubbing with Slurries and Dirty Liquors

V-tex® technology is specifically designed to offer high efficiency scrubbing with liquors containing high concentrations of solids. This could be slurries with double-digit percentage level suspended solids, sticky gelatinous solids formed as a hydrolysis product from the gas-phase contaminant, condensed tars forming an emulsion with or pure phase within the scrubbing liquor, or dissolved salts at close to their solubility limit.

In each of these cases and more besides, the physical characteristics of the scrubbing liquor mean that a packed tower or tray tower could not be used successfully as they would quickly block up, and a simple spray column would not achieve the scrubbing efficiency required for most applications, requiring additional polishing stages. By contrast, the unique design features of the V-tex® provide a clear advantage for robust scrubbing, extending the period between maintenance shut-downs and making that maintenance as trouble-free as possible.

For awkward scrubbing duties, contact ERG’s experienced sales team to find out how the V-tex® scrubber’s non-clogging, dual opposed spray nozzle and packing-free scrub chamber can work for your application.

Examples of ERG’s successful V-tex® scrubber installations for these types of applications include:

  • SiF4 and BCl3 are used in speciality gases for manufacturing LED screens and optical fibres and in the production of silicone for consumer and healthcare products. When these gases come into contact with moisture from the air or carrier gas, and in particular in a wet scrubber, they hydrolyse to form HCl or HF and gelatinous or crystalline SiO2 depending on the scrubbing chemistry. In multiple plants around the world, V-tex® is used to efficiently scrub the acid gas without rapidly fouling due to the silica.
  • An emergency chlorine scrubber designed for a shock load of almost 5 tonnes of chlorine discharged over 15 minutes at a metal refinery uses a batch of >20%w/w caustic solution which reacts to form >30%w/w sodium chloride solution. In a traditional scrubber, this solution would risk fouling the packing. ERG’s V-tex® scrubber provides robust, reliable chlorine removal when the plant needs it most, safe-guarding the health of the workers and the environment.
  • In the Middle East, ERG’s multi-stage flue gas abatement plant uses 15%w/w limestone and gypsum slurry to scrub >150,000ppm SO2. This desulphurisation plant removes >98% of the SO2 in the high efficiency V-tex® stages which are designed to minimise downtime. The plant also produces saleable gypsum as a byproduct. The V-tex® scrubbing is integrated with ERG’s complete wet abatement plant comprising a quench, high-energy venturi, subcooler, caustic scrubber and carbon polish to provide our client with comprehensive gas cleaning.
