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,…

Mercury Emissions – Control, Processes go commercial

    November 17 was the deadline for states to submit their plans for the control of mercury emissions from power plants to the U.S. Environmental Protection Agency (EPA, Washington D.C.; epa.gov), but mercury-control processes are already being commercialized. The…

Designing for A Safe Process

    Accidents do happen. While not everything can be predicted, addressing safety concerns throughout the design of a process can help to prevent accidents from occurring. Designing with safety in mind can also help to minimize potentially serious consequences…
