And, no matter what the specialty or application, most catalyst producers are in a constant state of research and development in order to meet the demands of their chemical processing customers, as well as to develop innovative catalysts for new applications and growing market areas. Recent efforts of some of the top catalyst producers are improving... http://www.che.com/extras/ps_and_corrections/9441.html Sun, 1 Jul 2012 0:00:00 EDT Throughout the chemical process industries (CPI), the need to drain a tank or process vessel arises. In batch-type plants, it is a regular occurrence and is one factor that affects the total cycle time per batch and ultimately the entire production capacity of the plant itself.  Figure 1. In a vertical... http://www.che.com/extras/ps_and_corrections/9398.html Fri, 1 Jun 2012 0:00:00 EDT A new catalyst that converts H2 and CO2 into formic acid under mild conditions has been developed by researchers at the Solar Light Energy Conversion Group of Energy Technology Research Institute, National Institute for Advanced Industrial Science and Technology (AIST; Tsukuba, Japan... http://www.che.com/extras/ps_and_corrections/9308.html Tue, 1 May 2012 0:00:00 EDT Distillation is one of the most extensively used operations in the chemical process industries (CPI). It is a highly energy-intensive unit operation, and continuously rising energy costs make it imperative to look for ways to reduce energy requirements. Some energy-saving configurations can increase capital investment costs, so the benefits need to be weighed carefully. Various techniques, such as heat integration, heat pumps, thermal couplings and others have been employed to achieve energy reductions [ 2–4]. Vapor-recompression-assisted distillation is one such technique to reduce energy consumption by utilizing the energy from the column overhead stream, with added external mechanical energy, to boil the bottom stream. This article illustrates the technique through an example of a typical C3-splitter (propane-propylene splitter) design wherein significant energy savings and operational benefits are achieved by using vapor recompression distillation. With the availability of reliable and proven compressors to handle large capacities for industrial use, this concept is gaining attention and merits consideration for new distillation installations.... http://www.che.com/extras/ps_and_corrections/9064.html Thu, 1 Mar 2012 0:00:00 EST The objective of this article is to present a stepwise understanding of how to calculate the NTU for a cooling tower, and thus to understand the basis of thermal design of counter-flow cooling towers for optimizing cost and performance.... http://www.che.com/extras/ps_and_corrections/8949.html Wed, 1 Feb 2012 0:00:00 EST Construction of a demonstration plant has begun for a biomass-to-gasoline process that boosts biomass conversion efficiency in producing bio-gasoline.
