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…
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…
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…
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,…
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…
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…
Understanding why rupture disks fail can help ensure that they don’t Even with the best process design, the unexpected can happen. Anticipating this, rupture disks are often installed as the last line of defense against the over-pressurization of equipment used…
DNV Software (Oslo, Norway; edlinks.chemengonline.com/6519-533) and The SimSci-Esscor unit of Invensys (Lake Forest, Calif.; edlinks.chemengonline.com/6519-534) have developed a link between the former’s Phastfx flammable-effects-software module and the latter’s Visual Flow safety-system-design software. The link allows process engineers to quickly and…
Although there has been big surge in biodiesel production recently, such fuels are not without problems of their own, such as low mileage, poor performance at lower temperatures, and adverse effects on engine components. Also, the production process for making…
A five-year research project to study the long-term potential for carbon-capture and storage (CCS) technology has been launched by the European Commission’s Director General for Research (Brussels). The so-called COâ‚‚ReMoVe project (for Research on COâ‚‚ Monitoring and Verification) will study…
