In this study, a dynamic simulator for three-phase gravity separators in oil production facilities is proposed. The mass conservation equation established to calculate the pressure, water level, and level separator balance of dispersed phase oil-water separation efficiency. proportional integral controllers are applied control pressure by setting opening three outlet valves oil, gas, water. model verified using field data means given valve controller parameters, respectively. Subsequently,...
Hydrate risk management strategy has become a promising way of dealing with hydrates in subsea transportation pipelines recent years. In this way, are allowed to form the pipeline and treated as slurry flow help anti-agglomerants. This work investigated effect hydrate formation on friction factor water oil (W/O) emulsion systems. A series experiments were conducted using high pressure loop. Results show that is direct proportion volume fraction formed, it increases significantly after onset...
Offshore pipelines are hailed as the “lifeline” of an offshore oil and gas production system essential for development. Component tracing technologies multiphase transmission pipeline networks need to be urgently developed predict fluid composition changes in networks. Instead assuming components constant, we consider they varied with flow. The component conservation equations a phase change model established. equation state is adopted determine equilibrium each real time. Considering...
On the basis of effective medium theory and classical viscosity prediction model proposed by Pal et al, apparent rheological properties water in crude oil emulsion with natural surface active components such as asphaltene resin are predicted. The adsorption entrainment continuous phase surfactants molecular, which leads to increment fraction, is inducement Non-Newtonian behavior bulk emulsion. two actions promoting counteracting effects on fraction considered separately represented Water...
Wax deposition modeling is complicated under oil/gas two‐phase pipe flow and therefore remains poorly understood. One‐dimensional empirical heat mass transfer correlations are unreliably for in stratified flow, due to non‐uniform deposit across the circumference. A mathematical model has been developed predict thickness wax fraction of using a unidirectional analysis non‐isothermal hydrodynamics heat/mass transfer. The predictions found compare satisfactorily with experimental data three...
This paper describes the problems in route optimization of two-phase pipelines. Combining hydraulic calculation with theory, this establishes an automatic model and adopts general genetic algorithm (gGA) steady-state (ssGA) to solve model, respectively, gets optimal route, discusses influence parameters setting result. was applied determining pipelines routes coalbed methane gathering transporting system Shanxi Province, China. The result shows that is feasible, which improves properties by...
A new simulator for gas–hydrate slurry stratified flow is presented, which can simulate the characteristics, including gas/liquid velocity, liquid holdup, and pressure drop. The includes an inward outward hydrate growth shell model two-phase hydrodynamic model. systematically considers kinetics limitations of formation, namely, mass– heat–transfer. composed mass momentum equations each phase as well energy balance considering heat generation related to formation. Thereafter, inclined...
Understanding the kinetics and viscosity of hydrate slurry in gas-water-sand system is great significance for high-efficiency high-safety development natural gas hydrates. The effect micron-sized sands with various concentrations particle sizes on formation, dissociation, are investigated this work. experimental results show that induction time sandy slightly prolonged compared to pure gas-water system, inhibition first strengthens then weakens as sand concentration increases from 0 wt% 5...
