The ever-increasing cost of fuel and relentless push for environmental responsibility are constant factors in the profitability of many chemical process operations, and fluctuations in the prices of natural gas and other fuels can make it hard to predict future energy costs and the impact of such fluctuations on profits. However, the impact of fluctuating fuel costs, and the regulatory uncertainty related...

Codexis (Redwood City, Calif.; www.codexis.com) and CO2 Solution (Quebec City, Canada; www.co2solution.com) have jointly developed a cost-effective method for capturing carbon dioxide from coal-fired power plants. Solvent-based systems for capturing CO2 are relatively well-understood, but they have not been widely deployed because they are energy-intensive and inefficient. Solvent-based approaches involve...

Athough the municipal water demand is considerably greater than that of industry, many of the municipal needs are addressed by relatively basic technologies, while industrial requirements can only be met with advanced treatment options. And, as industrial water demands continue to grow due to regulatory restrictions and mandates, water treatment providers are developing innovative desalination...

When it comes to managing regulatory documents such as product labels, bills of lading, and certificates of analysis (COA), virtually all manufacturers in the chemical process industries (CPI) face the same challenge — getting the right information into the right document formats for every shipment. This challenge becomes more complicated when you ship to customers with unique labeling and reporting...

A next-generation, carbon-enhanced membrane-bioreactor (MBR) system improves treatment of industrial wastewater with high organic content and containing compounds that resist microbial breakdown. The system allows economic reuse of wastewater or discharge to meet stringent environmental standards. The new MBR, dubbed EcoRight, will be commercially available in early 2011. First envisioned by Saudi Aramco...

As environmental awareness receives renewed focus in the government, the public and industry, it appears that higher standards will be applied to processors to achieve even higher oxides-of-nitrogen (NOx) removal than in the past. And since selective catalytic reduction (SCR) has been proven to be one of the most efficient systems for NOx removal from high output sources, such as coal-fired power plants...

With bio-based chemical production growing, and several newer companies ready to enter commercial production, indications are that biologically derived chemicals will be an increasing force in the petrochemicals market. But bio-based chemical producers must confront the bottom-line requirements of product performance and cost, rather than riding their products’ environmental benefits. Susan Sun...
