  • Cost reduction of solvent recovery in pharmaceutical plants – Case Study

    Use of Solvents The pharmaceutical industry relies on the use of large quantities of organic solvents in a great number of manufacturing steps including chemical synthesis, fermentation, extraction, formulation and finishing of products. Solvents such as acetone, methyl ethyl ketone and tetrahydrofuran are commonly used as reaction media and for extracting products in the pharmaceutical, ...

  • Solvent Recovery System Keeps Presses Rolling at World`s Largest Gravure Printing Plant

    When QUAD/GRAPHICS Inc. entered the publication gravure printing market, it followed the axiom of Daniel Burnham, the 19th century architect and urban planner, to 'make no small plans.' In 1985, the Pewaukee, Wis.-based printing company purchased two 96-inch web, eight-color, high-speed presses and installed them at its new printing plant in Lomira, Wis., near Milwaukee. Conventional wisdom at ...

  • Chlorinated solvents: methylene chloride and TCE

    Introduction This paper presents the results of a scaled and phased approach to source remediation of high concentrations of recalcitrant chlorinated solvent compounds via soil vapor extraction (SVE) and vapor treatment at a Site in Southern California. Phase I began with refrigerated condensation (C3) in order to achieve high mass removal rates to reduce lifecycle costs and time ...

  • Assessment of Activated Carbon Stability toward Adsorbed Organics

  • 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 ...

  • What carbon footprint? Asks Corus

    Problem In case you haven’t heard, our planet is getting warmer. At what rate it is occurring or how much human activity has to do with the increasing temperatures is a heated debate, pardon the pun. One thing we do know for sure…carbon dioxide (CO2) is a contributing factor in global warming and humans are responsible for a large portion of these emissions. If you had asked ...

  • Air Pollution Control in the Printing and Web Coating Industries

    For many U.S. companies in the printing and web coating business, the use of an Air Pollution Control System (APCS) to control harmful air pollutants is not new.  In these industries, depending upon their location, companies have been installing APCS since the early 1970's.  However, for some companies the clock is still ticking regarding their compliance with local, state and federal ...

  • What is Activated Carbon?

    Adsorption with activated carbon can apply. The more awareness people have of the Earth, the more applications activated carbons will have. is thus a commonly seen process in applications such as gas masks, space capsules, nuclear plants and so forth, in which the removal of gases is highly needed. ...

  • Case study - Coil coater asks...`What carbon footprint?`

    Overview Our planet is getting warmer. At what rate it is occurring or how much human activity has to do with the increasing temperatures is a heated debate. One thing we do know for sure is that Carbon Dioxide (CO2) is a contributing factor in global warming and humans are responsible for a large portion of these emissions. These days, many individuals and businesses alike are trying ...

  • Application of gas chromatography-mass spectrometry preceded by solvent extraction to determine volatile fatty acids in wastewater of municipal, animal farm and landfill origin

    This study describes extraction of selected volatile fatty acids (VFAs) (containing from 2 up to 8 carbon atoms) with methyl-tert-butyl ether (MTBE) from polluted aqueous samples followed by separation, identification and quantification by gas chromatography coupled with mass spectrometry (GC-MS). Extraction parameters such as time and number of extractions, volume ratio, effect of acidification ...

  • Removal of inorganics from sludge and digestate: the BiAR process

    This conference contribution will present a novel technology for renewable ash-free fuel production from low-value ash-containing feedstocks such as sludge digestate, wood bark or rice husks that cannot be utilized directly as a heating fuel, because of the high (low melting point) ash content. Biomass Ash Removal (BiAR) process introduces the low-temperature solvolysis in cheap solvents to ...

  • Put energy into emission control projects

    Many companies feel pressured to spend the least amount possible to meet environmental regulations, primarily because compliance isn’t a profit generating endeavor. What some environmental and compliance managers fail to realize is that emission control equipment can quickly become a profit decreasing endeavor with this penny wise-pound foolish approach. With mandatory greenhouse gas (GHG) ...

  • Treatment of high strength resin production wastewater case study

    Problem Full-scale Incineration of this wastewater had proved very expensive due to the fuel input required and the ongoing incinerator maintenance costs. The polymer manufacturer sought treatment alternatives to save money. Initial biotreatment pilot work indicated that biotreatment was not feasible using conventional activated sludge technology even when the concentrated wastewater was ...

  • Will the equipment match the regulatory method?

    Anyone involved in field analysis of oil in water will con tinually get the question "Does your equipment match the regulatory method?" Zj While the amount of oil in water is highly regulated, it can also be a challenging measurement. It is complicated by the fact that oil comes in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory ...
