Today’s chemical processors must cope with rising labor costs, increasing global competition, escalating fuel costs and more-stringent safety and environmental regulations. To improve productivity and reduce costs in today’s competitive environment, many facilities are operating leaner than even before. And, downsizing strategies have seen the reduction of maintenance staff, which often results...

Sparging refers to the process of injecting a gas through a diffuser into a liquid phase. It is used in both physical and chemical process applications. In physical process applications, the gas is used to either dissolve gas into liquid (such as aeration and carbonation) or to remove contaminants from the liquid phase (such as oxygen stripping, volatile organic compound stripping and water stripping). In...

There are two main reasons why compressor capacity regulation is used. The most prevalent reason is to adjust the suction flow to match the process demand. The second reason is to save energy. As a rule, capacity control is determined by the compressor discharge pressure. Compressor capacity-control methods are utilized to maintain a required delivery under variable process conditions [1]. In this article...

Pumps are among the most commonly used machines in the chemical process industries (CPI). Condition monitoring tests and predictive maintenance can help pump operators determine when to overhaul pumps in a way that minimizes costs. Despite pumps’ ubiquity and large energy demands, however, relatively little information is available on how to apply predictive maintenance approaches and condition...

Though times are changing, many of the traditional challenges associated with running a chemical processing plant remain the same. For years processors have been asking for leak-proof, high-performance valves, but it is only recently that valve manufacturers are employing new technologies, designs and materials that improve performance and reduce leaks.   Improved Cv values “Traditionally...
