To solve the problematic selection of turbulence model of coalescence plate for alcohol hydrocarbon separation in numerical simulation, through the combination of experiments and numerical simulations, by using the thickness of the oil deposition in the coalescing plate flow channel upper part as the analysis index, comparative analysis the simulation results of six commonly used turbulence models including Standard k-ω, SST k-ω, Standard k-ε, Realizable k-ε, Realizable k-ε and RNG k-ε. The error between the Standard k-ω turbulence model and the experimental value is the smallest, so it’s superior to the commonly used k-ε model in the literature. [ABSTRACT FROM AUTHOR]

Monoethylene glycol regeneration & desalination system is one of key units in deepwater gas development, often using evaporative crystallization and sedimentation theory to achieve high solubility salt (such as NaCl) removal. The main process parameters on the desalting flash tank, mainly optimized from the perspective of energy in the past, can only show the effects of process parameters on evaporation, but not directly show the effects on the crystallization and particles settling & separation. To study the main process parameters of flash separator as a crystallizer, the influence of temperature, pressure, and residence time on the crystal size distribution of NaCl in ethylene glycol solution was studied by laser diffraction particle size analyzer. The results showed that under the same conditions, the higher temperature, the more dispersive crystal size distribution and the smaller average particle size; the higher degree of vacuum, the more dispersive crystal size distribution and the smaller average particle size; too long or too short of residence time would cause the average crystal size to become small. For discussed solutions, optimized process parameters are that flash temperature is 140℃, pressure is -80 kPa, and the residence time is 5 minutes. The optimized parameters can achieve stable sedimentation separation and desalination by the verification of developed continuous experimental apparatus. [ABSTRACT FROM AUTHOR]

In the development of deepwater gas field, ethylene glycol is commonly used as hydrate inhibitor. Large amounts of salt contained in produced water caused scaling in the treatment of rich glycol liquid with high salt in common ethylene glycol regeneration system,which has serious impact to the offshore production system, even lead to suspend production. Therefore, the process of salt removal from ethylene glycol is supposed to be one part of ethylene glycol regeneration system for deepwater gas production. Models of the process of high solubility salt removal from ethylene glycol have been developed in process simulation program Aspen Plus, through which the effect of recycle temperature, ethylene glycol recycle flow rate, and water content of ethylene glycol on the salt removal process have been simulated and analyzed. The results showed that the salt removal process made a good performance with appropriate process parameters such as the flash pressure（absolute） of 0.15 MPa, the recycle heated temperature of 141~145 ℃, and the recycle flow rate is 60 times of the feed rate.
