Raw materials and energy represent two of the largest expenses in the chemical process industries (CPI). Energy reduction is necessary to sustain cost-effective production and manage capacity in the ever-changing CPI marketplace. Process simulation software can prove extremely valuable in evaluating energy reduction potential. This article discusses the successful application of process simulation software...

I will bet that many readers are familiar with a Teddy Roosevelt quote that includes the following: “It is not the critic who counts…the credit belongs to the man who is actually in the arena...” Ralph Weiland has been in the arena for many years, doing chemical engineering work that has benefitted many people. At the Spring AIChE meeting this month (Houston; April 1–5), the...

Carbone Lorraine (CL; Paris, France; edlinks.che.com/7372-538) is launching a new welded-plate heat exchanger, dubbed Heatex, which features plates made of tantalum CL-Clad. The patented CL-Clad technology involves the brazing of steel onto "reactive" metals, such as tantalum, titanium and zirconium, in order to fabricate columns, reactors and (now) heat exchangers used in corrosive service. Such...

Packed Columns [1] A packed column is a vertical, cylindrical pressure vessel containing one or more sections of a packing material over whose surface the liquid flows downward by gravity, as a film or as droplets, between packing elements. Vapor flows upward through the wetted packing, contacting the liquid and facilitating absorption of the vapor into the liquid. Packings are offered in either random or...

Mitsubishi Heavy Industries, Ltd. (MHI; Tokyo, Japan; edlinks.che.com/7368-533) is marketing a new process that captures carbon dioxide from flue gas (FG) for enhanced oil recovery (EOR). The KM-CDR process uses a proprietary amine-based solvent (KS-1) in a packed column to absorb and regenerate CO2 with less energy than conventional CO2 -recovery processes and with "far less" solvent loss...

    Most columns shut down without fires. Yet most refineries and chemical plants at some time or another have experienced spontaneous or hot work ignitions in at least one column. When this occurs inside a column during or after shutdown, the results can be devastating and dangerous. This paper concentrates on the fires related to packing in columns.   Many refineries and chemical plants...

A gas-liquid nozzle that reduces the size of the gas bubbles blown into a liquid — thus increasing the rate at which the gas is absorbed into the liquid — has been developed by a research team led by Jie Wu at CSIRO Manufacturing and Infrastructure Technology Div. (edlinks.che.com/5826-531), in collaboration with CPE Ltd (Chemical Plant & Engineering; both Melbourne, Victoria, Australia...
