The approaches currently used by process integration specialists to assess the opportunities for the integration of reboilers are frequently erroneous and lead to proposals that have to be rejected at the detailed engineering stages or worse, to commissioned reboilers that…
The Simetal EAF FAST DRI is a new electric arc furnace that is specially designed for the use of direct reduced iron (DRI). It allows a continuous melting process, as electric energy input and DRI are supplied during tapping (tilting…
Various misconceptions arise when it comes to the thermal design of cooling towers. Sometimes related parameters, such as range, approach, effectiveness, liquid-to-gas ratio ( L/G), wet-bulb temperature, cooling water temperature, relative humidity, number of transfer units (NTU) and other terms…
Green Biologics Ltd. (GBL; Abingdon, Oxfordshire, U.K.; www.greenbiologics.com), an industrial biotechnology company has merged with Butylfuel Inc., a U.S.-based renewable chemicals and biofuels company. The new company will operate under the Green Biologics name and will continue to be headquartered…
In the long run (a few hundred years, perhaps) humans will exhaust the Earth’s current supply of fossil fuels. It is more accurate to say that before we exhaust the supply, humans will stop burning fossil fuels to produce electricity…
In the chemical process industries (CPI) it is relatively common to use a homogeneous two-phase flow model to predict the pressure drop through the shell-side of horizontal heat exchangers that handle two-phase mixtures. Recent experimental studies reported by HTFS [1,…

Steam traps are designed to allow condensate, but not steam, to escape from a steam line. When they malfunction, however, numerous costly consequences can result including energy losses, insufficient heating to processes, maintenance issues and more. At its Global Users…
Articles about thermal fluid systems often start with a variation of the statement that “thermal fluid systems typically require little ongoing maintenance for the first few years of operation” and then go on to extol the various advantages of indirect…
Kalocer high-alumina ceramic mosaics can line a variety of plant components quickly and easily. Kalocer mosaics come in a variety of sizes and shapes, including square and hexagonal with dimensions of between 10 x 10 mm to 25 mm length…
