Features of control high-gradient electromagnetic rotary separators are considered. Structural diagrams systems with fuzzy logic controllers the process separation given. A new block diagram a hybrid system for rotary-type separator combining classical and intelligent con-trol methods has been proposed. The example shows that can significantly increase energy efficiency in electrical technologi...
The Gas Liquid Cylindrical Cyclone (GLCC) separator is an attractive compact separator alternative to the conventional vessel-type two-phase flow separator. Thus, it is important to develop predictive tools for design and to be able to improve the technology of the GLCC. Previous studies on the GLCC have focused on mechanistic models capable of predicting the operational envelope for liquid car...
For improved cross section measurements of the reaction Cða; gÞO in inverted kinematics, a recoil separator ERNA is developed at the 4MV Dynamitron tandem accelerator in Bochum to detect directly the O recoils with high efficiency. The O recoils are produced by the C projectiles in a windowless He gas target. We report on the charge state distribution of the O recoils, the gas target density, t...
A highly transient flow regime called riser slugging can develop in pipelines from wellheads to separation tanks which introduces severe oscillations of pressure and flow rates in off-shore processes. Mitigation of the intensity of riser slugging may be achieved via anticipative control actions on valves positioned at the entrance and at gas/oil exits of the separators. In Phase 1, this work is...
It is also common for flowmeters to be installed downstream of a two or three phase separator. If the well conditions change or the separator has been incorrectly sized, then it is possible that the oil liquid outlet may have some gas carry under. The effects of gas entrainment on the output of ultrasonic and Coriolis meters has been reported previously [1] [2]. It is already known that gas ent...
supersonic separators have found extensive applications in dehumidification of natural gases since 2003. unlike previous studies, which have investigated the inlet conditions and nozzle geometry of supersonic separators for pure fluids, the present study employed a combination of momentum, heat, and mass transfer equations along with virial equation of state (eos) to inspect the effect of inlet...
Investigation on the Separation Performance of a Multicyclone Separator for Natural Gas Purification
This study evaluated the separation efficiency and developed a pressure drop model for a multicyclone separator used for natural gas purification. The collection and grade efficiencies of a multicyclone separator with 15 single cyclone separators were evaluated at inlet velocities of 6–24 m/s and particle concentrations of 30–2000 mg/m at atmospheric pressure and room temperature. The experimen...
In pipeline-riser systems, pressure fluctuations which result from the formation of large liquid slugs and gas surges due to operational changes or low mass flow rate from production wells and the profile of pipeline-riser systems often lead to trips at the inlet of the separator; and thereby, the problem causes a a loss of the production.In this study, on a sample deep-water oil field off the ...
the mixing behavior of the gas-liquid phase in three loop bioreactors was investigated. a gas-induced external airlift loop bioreactor (ealb), a forced-liquid vertical tubular loop bioreactor (vtlb) and a forced-liquid horizontal tubular loop bioreactor (htlb) were used for mixing studies as well as biomass production from natural gas. the effect of design parameters, riser to downcomer cross s...
