Permit-Required Confined Spaces
This new U. S. Occupational Safety and Health Administration paper describes OHSA's confined-space satndard, and discusses how to meet it by controlling hazards, administering entry permits and assigning duties, as well as how to deal with emergencies and OSHA assistance available.
Properly Clean Organic Heat Transfer Fluid Systems
Maintaining peak performance of organic heat transfer fluids can require removal of dirt and pipe scale, oxidation, thermal degradation, and process contamination. This paper describes the appropriate cleaning techniques for dealing with solids; sludge, high-viscosity fluid and residues; process contamination; and hard coke.
Succeed at Dynamic Modeling of Batch Reactors and Batch Distillation
This paper reviews the basic techniques for dynamic modeling of these two key operations. It covers considerations related to heat transfer, reaction chemistry, mass balances and the control system. It also discusses equipment configurations, performance characteristics and operational constraints.
