Trapping CO2

For developing a new technology that traps carbon dioxide and other pollutants so they can be removed, researchers from the University of Bath's Dept. of Chemical Engineering (edlinks.chemengonline.com/6893-551) have received the £185,000 Brian Mercer Award for Innovation from the Royal…

Hearing Protection For CPI Workers

    Occupational dangers in the chemical process industries (CPI) are many, with falls, respiratory hazards, and explosion risks confronted daily. One hazard, however, causes no pain nor visible scars. Its effects accumulate with each overexposure and can go unnoticed,…

Cellulosic bioethanol

Mascoma Corp. (Cambridge, Mass.; edlinks.chemengonline.com/6892-541) has received a $14.8-million award from the New York State Dept. of Agriculture and Markets and the New York State Energy Research and Development Authority to build and operate a biomass-to-ethanol demonstration plant in Rochester,…

Green chelating agent

Akzo Nobel (Amsterdam; edlinks.chemengonline.com/6892-546) has commercialized a biodegradable chelating agent, Dissolvine GL, as a cost-effective, green alternative to the two most frequently used agents, ethylenediamineetetraacetic acid (EDTA) and nitrotriacetic acid (NTA). The product contains L-glutamic acid (from sugar, molasses, corn…

VOC Emission Controls For the CPI

    Why do governmental bodies regulate VOC (volatile organic compounds) emissions? Because these compounds react with nitrogen oxides to produce ground-level ozone. VOC emissions have many names: hazardous air pollutants (HAPs), non-condensable gases (NCGs), or just plain “organic vapors.”…

Biofuel

Subsidiaries of Shell Oil Co. (Houston, Tex.; edlinks.chemengonline.com/6891-547) and Codexis, Inc. (Redwood City, Calif.; edlinks.chemengonline.com/6891-548) are collaborating to enhance methods of converting biomass to biofuels. Shell, already one of, if not the leading, distributor of transportation biofuels, says it is…

Design Safer Solids Processing Plants

    Chemicals, plastics, pharmaceutical, food, agricultural chemicals, coal and bio-chemical industries have a wide array of processes where the raw materials, intermediates and products are in particulate form. Hazards associated with particulate solids are unique, and in most cases…

Damper Technologies for Regenerative Thermal Oxidizers

    Regenerative thermal oxidizers (RTOs) are commonly used for controlling volatile organic compound (VOC) emissions from a broad spectrum of industries. An RTO is basically a thermal oxidizer that uses ceramic media as the heat exchanger medium, providing high…

Securing chemical Process facilities

    Security is on everyone’s mind. Heightened awareness and concerns have affected the way we live and the way we work. Those of us who are part of the chemical process industries (CPI) and have a great respect for…

An improved production process for solar-cell Si

With the aim to commercialize a new process for making solar-cell grade (SOG) silicon, Chisso Corp. (Tokyo, Japan; edlinks.chemengonline.com/6891-534) is negotiating the possibility of establishing a joint-venture company with Nippon Mining Holdings, Inc. (Tokyo) and Toho Titanium Co., Ltd. (Chigasaki,…
