This app provides the detailed optimum design of three-phase separators for any given process conditions. Both vertical and horizontal orientations and various design types, i.e. simple, boot, weir, and bucket & weir, are covered. All well-known classical methods, i.e. GPSA, York Demister, Theoretical, as well as the modern CFD-based approach are included, and their produced results can be compared against each other. Optimization methods, such as golden-section search, and bisection method have been used through each method to optimize the surge/holdup/level control compartments. Note, the popular classical methods are too conservative and usually specify unnecessarily oversized separators. On the other hand, the CFD-based approach proposes more economical separators that can successfully accomplish the separation task. So, your practical design projects can get tangible benefit from this swift sizing app! For background information and technical support, please refer to http://www.salvasolution.com.
