Reducing design time; this software allows users to evaluate conceptual designs in a timely fashion
Article Abstract:
Advanced Chemical Systems International, Inc. (ACSI) found out the benefits in using the Vellum software, a 3-D CAD program that quickly defines concept designs. Ashlar Inc.'s software was utilized by ACSI to develop its trimethylphosphite (TMPI)-repacking system. The method is being used by the semiconductor-maker to ensure that high-purity chemicals being repackaged remain immaculately clear during manufacture. It was possible to complete the design in 12 hours with the Vellum system compared to the 36 hours it would take using he conventional system.

Heat transfer in agitated jacketed vessels
Article Abstract:
Heat-transfer and temperature-control principles are the main operating systems of agitated jacketed vessels. A quick review of the principles of heat transfer and temperature control is presented. Tables showing equations for calculating inside and outside film coefficients and the Reynolds, Prandtl, et al computations are also included. Various operation settings such as continuous, batch heating and cooling, and control, tracking and calorimetry are also discussed.

Getting a firmer grip on process control
Article Abstract:
Lyondell Chemical Co. has installed a Process Perfecter non-linear multivariable controller on its two-distillation-column setup for isolating isomersat its plant in Lake Charles, LA. The controller was installed to reduce impurity levels and improve the reliability of the unit. Lyondell Chemical reported that the controller was online 99% of the time and reduced the impurity level of the meta-isomer by 9%. The controller was supplied by Pavilion Technologies Inc.
