While the Pennant ECS can be put to multiple applications, multi-bagger benefits accrue with its ability to convert both saturated and superheated steam into clean electrical energy. Typically, the ECS is used in parallel with a Pressure Reducing Valve (PRV) or Pressure Reducing Desuperheater Station (PRDS) situated downstream of the boiler. The ECS, configured in the above arrangement is able to smartly...

Although halons (brominated or chlorinated fluorocarbons) are widely used as fire suppressants and foaming agents, they also contribute to stratospheric ozone depletion. However, halons are potentially valuable chemicals that should not be destroyed, but rather converted to reusable chemicals, says Bogdan Dlugogorski, professor of chemical engineering in the school of...

    Kermit the Frog once said, “It isn’t easy being green.” While this may be true, industry is still making the effort. Both in the U.S. and abroad, processors are not only striving to produce environmentally friendly products, but also are becoming more mindful of the impact of their operations. More often than not, cleaning up both products and processes requires the use of...

    Fouling is one of the most vexing problems in water-treatment systems that use membranes to remove suspended and dissolved particles. The deposition and accumulation of these substances on membrane surfaces inevitably lead to loss of performance for the membrane [1]. While there are several strategies for reducing fouling, the right solution varies with the process and type of fouling.  ...
