  • The impact of tower internals on packing performance

    The overall tower performance is influenced by the type of both tower internals and random packing. The Raschig GmbH's most recent development is the Raschig Super-Ring®, the fourth generation of random packings. In 1998, the Raschig Super-Ring No. 2 was tested at the facilities of Fractional Research Inc. A significantly improved capacity and pressure drop over other random packing was ...

  • Direct contact heat transfer using No. 2 Type-K Tellerette® Tower Packing

    A customer with a sulfuric acid reclamation facility needed to cool a saturated air stream or closed loop process operation. The 10,000 CFM air stream at 165° F. had to be cooled to 110°F. The existing equipment was only able to achieve 125°F. Cooling liquid availability included a large quantity of processed water at 110°F and a smaller amount of city water at 55°F. Verantis recommended ...

  • 3.5` LANPAC® proven superior for removing PCE from groundwater in packed tower air strippers

    The problem Dry cleaning fluids have contaminated groundwater supplies in all areas of the United States. One of the most common contaminants is PCE (perchloroethylene or tetrachloroethylene, Cl2C=CCl2). As a suspected carcinogen, PCE must be removed from water to very low levels. The US EPA maximum contaminant level (MCL) for PCE in drinking water is 5 ppb (5 parts per billion, or 5 mg/L). ...

  • To Automate Where no Plant has Automated Before: Acid Washing of Packed-Tower Chemical Scrubbers

    ABSTRACTThe Orange County Sanitation District (Sanitation District), under a capital improvement project, developed an automated procedure to perform acid washing on packed tower chemical scrubbers. Packed-tower chemical scrubbers operate with an alkaline solution, composed of sodium hydroxide, an oxidant, and make-up water. The make-up water may be chlorinated secondary treated wastewater or ...

  • Continuous emission monitoring and control of packed tower odor control systems using the sycamore CEM

    ABSTRACT Packed-tower chemical scrubbers, with sodium hydroxide (caustic) and sodium hypochlorite (bleach), are commonly used to treat foul air from wastewater treatment processes. The available control mechanisms include a pH probe and controller for the sodium hydroxide feed, an oxidation reduction potential (ORP) probe with a controller toestablish the bleach feed, and proprietary ...

  • 3k-tellerette packing-hclremoval-crossflow-scrubber-302

    A number of sources in the wastewater treatment process such as the headworks, aeration tanks, settling tanks and dewatering press can produce high-intensity odors from gaseous sulfide emissions. The most common sulfides arehydrogen sulfide (H2S) and methyl mercaptan (CH3SH.)The highlighted installation was for a major municipality in the southeast and utilizes our new high efficiency 3-K ...

  • Upgrade Fill Media to Improve Cooling Tower Efficiency

    One of the simplest and most cost-effective ways in which to extend the life of a cooling tower, improve heat transfer efficiency and reduce maintenance downtime, is to upgrade the cooling tower’s fill media to components constructed out of robust and non-clogging materials such as Polypropylene (PP), PVC or stainless steel. Fill is a critical component in the heat transfer ...
