Capabilities of the Adsorbent Tube Injector System (ATIS™)

by Sigma-Aldrich Co., LLC     based in Bellefonte, PENNSYLVANIA (USA)

The Adsorbent Tube Injector System (ATIS) was developed at Supelco® by R&D Scientists, as a tool to assist in our comprehensive adsorbent research for thermal desorption tubes. The ATIS provides an efficient means of transferring calibration standards in either the gas or liquid phase onto the adsorbent packed tubes. The ATIS employs the technique of flash vaporization to vaporize the sample in a continuous flow of inert gas; the inert gas carries the sample to the tube. The sample pathway of the ATIS is constructed of glass and stainless steel. The calibration standard is injected by a syringe through a replaceable septum in the center of the injection glassware, which is heated. After enough time has elapsed, typically less than five minutes, the tube is removed from the ATIS and analyzed using the appropriate analytical technique for that adsorbent tube.

Odor Scrubbers Applications with Hydrogen Peroxide

by USP Technologies     based in Atlanta, GEORGIA (US) (USA)

Hydrogen Peroxide as a Replacement for Sodium Hypochlorite Hydrogen peroxide may be used in both mist scrubbers and packed tower scrubbers as a replacement for sodium hypochlorite (bleach). Like bleach, the process involves two concurrent mechanisms: 1) absorption of the odors (H2S) into the alkaline scrubbing solution; and 2) oxidation of the absorbed sulfide in solution. Step 1: H2S + NaOH → NaSH + H2O Step 2: 4H2O2 + H2S → H2SO4 + 4H2O Typical dose ratios are 5 parts H2O2 per part H2S or, when used in place of bleach, one gallon 50% H2O2 for every 10 gallons of 15% sodium hypochlorite (NaOCl). This generally translates into a break-even cost scenario. Sufficient caustic soda (NaOH) is added to maintain a pH of 10.0 - 10.5 in the scrubbing solution. There is also in practice a process which uses H2O2 in series with bleach to scrub composting odors. This process relies on a series of three packed tower scrubbers: the first is a pH neutral water wash (to remove ammonia and amine odors); the second uses a conventional caustic/bleach solution in which the bleach is purposely overdosed (to oxidize the complex organic sulfur odors); and the third uses a caustic/H2O2 solution (to remove the unreacted chlorine vapors carried over from the second stage). H2O2 + HOCl → HCl + H2O + O2 Typical dose ratios are 0.5 parts H2O2 per part hypochlorite (OCl-), with sufficient caustic soda (NaOH) added to maintain a pH of 8.5 in the scrubbing solution.

Integrated real-time gas analysis solution for chemical decontamination industry

by CIC Photonics, Inc.     based in Albuquerque, NEW MEXICO (USA)

The threat of terror in the form of chemical and biological warfare agents has been a reality globally since March 1995, when the Aum Shinrikyo sect killed 12 people and injured nearly 6,000 by releasing sarin nerve gas in the Tokyo subway system. More recently, the 2001 anthrax attacks in the USA was a wake-up call that the threat is real. Recent outbreaks of H1N1 and SARS posed threats of worldwide epidemics because air travel provides a means for these diseases to spread globally in less than 24 hours. A major concern of several US government agencies, such as the Department of Defense, Homeland Security, and the Centers for Disease Control and Prevention is not only the detection of hazardous chemical and biological warfare agents (CBWA) or bacteria or viruses that pose an epidemic threat, but the timely decontamination of those agents to a level where they no longer pose a threat to human health and life. The solution requires a means to monitor the effectiveness of the decontaminating reactant or reactants to an endpoint that has been reliably shown to be more than 99% effective in rendering the targeted agents harmless under controlled conditions.

Parts cleaning wastewater solution

by ENCON Evaporators     based in Hooksett, NEW HAMPSHIRE (USA)

Parts cleaning wastewater is a common application for ENCON Wastewater Evaporators. Parts cleaning is almost entirely water-based since the Montreal Protocol forced companies to abandon chlorinated fluorocarbons (CFC’s) and solvent degreasers. The wastewater is generally brownish gray and translucent with a soapy appearance. It may have trace settled solids and floating oil.

Dye penetrant wastewater treatment

by ENCON Evaporators     based in Hooksett, NEW HAMPSHIRE (USA)

Dye penetrant wastewater includes the presence of a fluorescent dye at about 2-3% in the wastewater. Dye penetrants are used as a method of testing weld integrity to confirm there are no leaks. Dye Penetrant wastewater cannot be simply flushed down the drain. Many companies choose to avoid the headaches of labor-intensive wastewater treatment technologies such as chemical treatment or filtration and simply pay to haul the wastewater. This however, can become quite expensive.

Odor Control for Composite

by OMI Industries (OMI)     based in Long Grove, ILLINOIS (USA)

A Single Solution To Manage Composite Odors

Many resins used in the composite industry emit styrene vapors which are considered hazardous in high concentrations and whose odor is an unpleasant nuisance. This gas is categorized as a volatile organic compound (VOC) and listed by the United States Environmental Protection Agency (US EPA) as a Hazardous Air Pollutant (HAP). Styrene is considered highly reactive in the atmosphere and may contribute to smog formation and the production of secondary air pollutants.

Solutions for the vapor suppression

by The BioSolve Company     based in Lexington, MASSACHUSETTS (USA)

BioSolve Pinkwater is used at major remediation and construction work-sites where excavation of contaminated soils may release noxious organic odors or hazardous VOCs. The dilute solution is sprayed directly onto newly exposed soil surfaces or stockpiles of contaminated material where volatilization is taking place. Used as an alternative to foam, Pinkwater creates a barrier that keeps vapors in the soil, allowing work to continue safely without disruption to workers or neighbors.

Gas detection analyzers for processing ovens & dryers

by Control Instruments Corporation     based in Fairfield, NEW JERSEY (USA)

Many industries are involved in coating products with solvent-borne materials and then employing ovens or dryers to remove the solvents from the finished product. The key hazard is an explosion from the build up of solvent vapors in the oven or dryer atmosphere. This buildup could occur by a malfunction in the production process such as: a sudden or improper amount of coating, a change in ventilation controls or excessive speed. In any of these cases, the concentration of flammable vapor has an opportunity to rise above safe levels, creating a potentially explosive mixture of vapor in air.
