  • Chlorinated solvent soil vapor extraction (SVE) remediation case study 2005

    Project Description An active industrial facility in South Central Los Angeles was impacted by tetrachloroethylene (PCE) and trichloroethylene (TCE; former staging area degreasing) operations as a part of its operations. A phased approach to soil vapor extraction (SVE) remediation was employed: the goal of Phase I was to attain high contaminant mass removal rates with very high VOC vapor ...

  • Analytical Devices for the Measurement of Water Vapor and Hydrocarbon Dew-Point in Natural Gas

    Introduction The determination of water vapor (water dew point) is crucial in the processing, custody transfer and transport of natural gas. High levels of water vapor in a natural gas stream can lead to a number of problems which include the formation of hydrates and the contribution to corrosion of plant and equipment. Furthermore, water vapor present in natural gas streams affects the ...

  • Redwood City Case (In Situ Gas Thermal Remediation + C3 Technology (GTR™+C3))

    The former Dry Cleaner site was located in Redwood City, California, contaminated by tetrachloroethylene (PCE). Affected soils also contained low levels of PCE degradation byproducts, such as trichloroethylene (TCE), and were presumed to have an approximate extent of 384 square feet (16’ x 24’ area) to a depth of 10 feet beneath the building. The remediation goal was driven by vapor ...

  • Seawater desalination at rabigh refinery

    Background Saudi Aramco’s RABIGH Refinery in Saudi Arabia wanted to install facility for 10000 TPD Seawater Desalination for the industrial use. The facility was supposed to be a BOOT (Build Own Operate Transfer) basis. General project description The joint consortium of SETE & Aquatech was successful in meeting the strict guidelines of Technical ...

  • Refinery remediation: fuel recovery and recycling

    Introduction The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a ...

  • Vaccu.Lan for Green

    You're building a 'green' science building, and some of your laboratories require vacuum support. How do you provide vacuum for those labs? You can't use an oil-sealed rotary vane vacuum pumps in the labs. The oil mist would contaminate the laboratory air, and the noise pollution makes the working environment unpleasant. The pump oil would quickly be contaminated by biological and chemical ...

  • Cryogenic Treatment Unit (TU-51) for Recovery of VOCs for Soil Remediation

    A Cryogenic Treatment Unit or TU-51 was developed to apply a cryogenic air treatment process to recover persistent vapor phase volatile organic compounds (VPVOC) having extremely low boiling points.
