In my October 2011 column (A window into kettle reboiler secrets, Chem. Eng. p. 28) I briefly described FRI’s early work using two windows on its industrial-size kettle reboiler. Subsequent to that, FRI had performed appreciable heat-transfer work. All of…
In an integrally geared centrifugal compressor (Figure 1), several impellers are mounted on the ends of high-speed pinion shafts, which are rotated by a bull-gear. Each impeller’s casing is mounted directly on the horizontally split gear casing. As is the…
Using gravity to initiate flow in the discharge of solid materials from bins and hoppers is the simplest, and often best, approach to solving solids-handling challenges. However, not all solid materials flow well by gravity alone. The propensity for fine…
The International Powder & Bulk Solids Conference and Exhibition is taking place May 6–8 at the Donald E. Stephens Convention Center in Rosemont, Ill. Featuring a large expo hall and a variety of technical sessions, as well as some hands-on…
Pressure variations resulting from the oscillatory flow patterns found in positive-displacement machinery, especially reciprocating compressors, are referred to as “pulsations.” Found in both liquid- and gas-handling systems, pulsations are a common phenomenon in the chemical processing industries (CPI). Operational problems…
Adjustment and control of moisture levels in solid materials through drying is a critical process in the manufacture of many types of chemical products. As a unit operation, drying solid materials is one of the most common and important in…
