Cyclone separators are considered one of the most common and widely used method separating solid particles from fluids. The focus this paper was to design a separator that could effectively improve air quality an industrial working environment by considering factors such as nature restrictions on device size operating condition. To do so, sample dust studied determine characteristics aluminum d...

The lift-gas allocation problem with pressure-drop constraints and well-separator routing is a mixed-integer nonlinear program considerably hard to solve. To this end, a mixed-integer linear programming formulation was developed by multidimensional piecewiselinearization of pressure drop functions using standard (CC) and logarithmic (Log) aggregated models. These models were compared by means o...

We present a procedure for the profiling of the volatile carboxylic acids and neutral compounds in blood or urine using the direct injection of the acidified sample into a gas chromatograph interfaced with a mass spectrometer by a jet separator. The non-volatile components remain at the head of the SP-1000 column while the volatile components move through the column. Up to sixty physiological s...

By the Bogoliubov prescription and the method of Gross and Pitaevskii in quantum field theory, the relativistic almost ideal Bose-Eintein gas at zero temperature is discussed. Special attention is given to the study of a vortex in the gas. The field description and fluid approximation are compared. PACS: 11.10.-z, 05.30.Jp, 47.75.+f, 47.37.+q

Over the last 20 years, a number of multiphase flow measurement techniques have been developed for metering oil (or condensate) / water / gas commingled streams. The available techniques can be characterized as those that operate inline or with partial separation. The inline variety typically consists of several meters or measurements and a central computer to interpret the signals and calculat...
