  • Measurement of Chlorinated Hydrocarbons with an 11.7 PID (.pdf)
    Analyzers, LLC, 780 Corporate Park Dr., Pembroke, MA 02359. T 1 781 709 2131; F 1 781 709 2050; web www.hnu.com; email: sales@hnu.com. Fig. 1 Schematic of a PID. Fig. 2 Model 102+ with Multiple Sensors. 2. Applications. Chlorinated hydrocarbons are among the. most common organic compounds found
  • Chlorinated Groundwater Treatment
    devices would contain Volatile Organic Compound (VOC) laden air that would require further treatment before being released to the atmosphere. The expected VOCs included benzene, chlorobenzene and dichlorobenzene. The design-builder required a treatment system that could destroy 99% of the VOCs
  • Capturing Organic Vapors from Non-Condensable Gases Using Activated Carbon Technology
    There are many established uses of vapor phase carbon adsorption technology in the chemical industry. The majority are to capture organic vapors from non-condensable gas streams, such as process exhausts. Other applications include process gas separations such as the removal of oxygen from air
  • "No-Solvent" Oil-in-Water Analysis - A Robust Alternative to Conventional Solvent Extraction Methods (.pdf)
    Most oil-in-water analysis methods for produced water require the oil to be extracted into an organic solvent prior to measurement. Many of the organic solvents used for extraction are either extremely flammable, hazardous to human health or both. The chlorinated hydrocarbons are very expensive
  • High Performance Mass Spectrometry of Persistent
    classes of persistent organic pollutants (POPs) which. may include polyaromatic hydrocarbons (PAHs),. halogenated PAHs, polychlorinated biphenyls (PCBs),. polybrominated diphenyl ethers (PBDEs), and new. hazardous compounds resulting from industry attempts to. stay ahead of regulation. Although
  • Monitoring Fugitive Emissions in the Workplace
    Organic solvents used in industrial processes must be handled carefully. Their affects on the human body can have some serious, even fatal, consequences. For example, inhalation of Chloroform, a dangerous volatile chlorinated hydrocarbon, can cause dizziness, drowsiness, nausea and respiratory
  • Organoclays Trap PNAHs and Creosote in Permeable Barriers (.pdf)
    Permeable barriers at creosote containing sediments near wood treating plants, require a barrier which is permeable and, at the same time, traps creosote plumes which contain such organic hydrocarbons as PCP and other chlorinated phenolic compounds. Lab tests and actual field applications have
  • Pemaco Superfund Site Remediation
    technologies used would include Electrical Resistance Heating (ERH), Soil Vapor Extraction (SVE), thermal oxidation, acid gas scrubbing and carbon absorption. The goal was to completely remediate the 1.4-acre site of these Volatile Organic Compounds (VOCs) and redevelop it as a public park. The vapor
