Chemical regulatory compliance is growing in complexity as product sourcing and formulations proliferate and organizations expand into new markets on a global scale. Staying current with the requirements of international regulatory initiatives such as the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) and the Registration, Evaluation and Authorization of Chemicals (REACH) adds...

Chemicals in production and laboratory environments alike have three distinct lifecycle phases: the first is procurement and inventory storage; the second is use in a manufacturing process or research program; and the third is post-use, including onsite handling, removal and beneficial reuse, recycle or disposal. A number of considerations including regulations, safety, material utilization efficiency...

Much attention over the past two years has been focused on alternative energy and green chemistry. So it is particularly appropriate that Chemical Engineering’s (CE) 2010 Personal Achievement Award recognizes two individuals with expertise in those fields. Last month, at an award ceremony held at the ChemInnovations Conference and Exhibition in Houston, Tom McGowan, a longtime consultant in biomass...

Because the global chemical process industries (CPI) encompass so many varied industry segments — including the conversion of raw materials and intermediates into chemicals and petrochemicals, fats and oils, paints and coatings, food and beverages, the refining of petroleum, the production of pharmaceuticals and others — there is considerable overlap in terms of the types of equipment...

Question: How are hydrocarbons best removed from water? Answer:  First, the type of hydrocarbons present must be identified. Typically, the hydrocarbons in question are in the form of oil or an oil-like substance. In that case, the miscibility of oil will have a major influence on the process used. If the oil is immiscible in water and the droplet size is large, the droplets will probably rise rapidly...

U.S. Energy Secretary Steven Chu today announced the selection of 22 projects that will accelerate carbon capture and storage research and development for industrial sources. Funded with more than $575 million from the American Recovery and Reinvestment Act, these R&D projects complement the industrial demonstration projects already being funded through the Recovery Act. Together, these projects...

As components of chemical research facilities, fume-hood exhaust systems for laboratory workstations are often taken for granted. Yet the choice of exhaust system, when designing or specifying a laboratory workstation, can have a tremendous impact on the safety of the laboratory building’s occupants as well as those in adjacent buildings. The choice of a fume-hood exhaust system can also affect a...

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...
