Mobility as a “megatrend” has recently become the latest buzz-word, and synthetic rubber producers are boosting production capacities to meet the anticipated demand for more tires. At the same time, high fuel prices and increasing concern for the environment are driving innovations in rubber to make tires more fuel-efficient (see box on p. 19). Meanwhile, efforts to find more efficient ways to...

For years it has been the common practice to treat process water with various chemistries to prevent scale, corrosion and microbiologicals. However, as regulatory issues tighten, water scarcity becomes a growing concern and the cost of treatment chemicals increases, chemical processors are finding that stringent treatment chemicals are not the only answer. Instead, they’re relying upon a multi-prong...

For years, clay has been the go-to product for spill containment simply because it was cheap and did the job. While clay, also referred to as diatomaceous earth, sand or kitty litter, will always have a place in in spill containment, if it’s the only product being used to clean up hazardous and other spills, it could be costing your facility more than you realize. With more modern options available...

Motorists filling up at U.S. gasoline stations these days may think that petroleum refiners are making good profits, but it depends on where the station gets its fuel. The industry is plagued by overcapacity and is concerned about government regulations that call for greater use of renewable fuels and tougher pollution control. The National Petrochemical & Refiners Assn. (NPRA, Washington, D.C....

As chemical processors continue their quest to process more with less equipment, they are seeking reactors capable of helping with this endeavor. For this reason, many are turning to continuous flow reactors because they provide scaleability and flexibility. However, vendors of specialty batch reactors are making every effort to provide these same characteristics in their models, as well. As a result...

  The chemical process industries (CPI) are looking for ways to decrease and control costs, and mixing operations are not exempt from this belt tightening. But because mixing is vital to most chemical processes, it can’t be eliminated. As a result, processors are clamoring for mixing equipment that provides more functionality so they can perform more tasks with less equipment.  Figure 1...

Traditionally, most students have learned about chemical reactions in laboratories using test tubes, beakers and flasks. Those who have gone on to discover and develop new products have typically done so using these batchwise techniques. This mind-set has continued through the piloting and scaleup phase, so that today, many chemical products are produced batchwise in large, continuously stirred reactors...
