Distillation Performance of Some Vertical Plate Type Packings under Reduced Pressure

Choosing Trays and Packings for Distillation

Distillation towers are essential to the chemical process industries (CPI), so it is imperative that they are properly designed and operated. Tower internals are arguably the most important piece of process equipment, since they cannot easily be accessed after startup. If the tower internals malfunction, the distillation tower will follow suit and the entire chemical process will suffer. This a...

Performance study of a diaphragm type crankcase pressure control valve

Pressure control valve (PCV) is implemented in internal combustion engine to regulate crankcase pressure. In this study, the performance of a diaphragm PCV valve is investigated numerically and experimentally. Firstly, numerical simulation is carried out using commercial code to predict the flow and pressure distribution inside the valve. Furthermore, downstream and upstream pressure of the val...

Distillation Columns with Structured Packings in the next Decade

The analysis of the history of structured packings allows the conclusion that the innovation cycle will become faster. Based on the separation power as an alternative way to represent the performance characteristics an estimate of the next level of what might be the ultimative separation power is given. Regarding the column internals like distributors only slight improvements are expected, typi...

Quadrilateral folded plate structure elements of reduced Trefftz type

General strategy for developing finite elements of general geometric shape explained on quadrilateral folded plate structure element ensuring invariance properties is presented in this paper. The basic idea of this strategy consists in using the natural coordinate system only for defining the element geometry and performing the element integration in a mapped biunit square. For defining the app...
