Optimizing and Stabilizing the Gas Lift Operation by Controlling the Lift Gas Specific Gravity
One of the factors which affects the gas lift performance is specific gravity of a lift gas (or the Molecular weight), which can influence the gas solubility in oil and has a direct effect on the gas lift performance. There are some previous researches which have included the lift gas specific gravity in their modeling, but in none of them, a comprehensive research about the effect of lift gas ...
متن کاملPreventing Instability Phenomenon in Gas-lift Optimization
One of the problems that sometimes occur in gas allocation optimization is instability phenomenon. This phenomenon reduces the oil production and damages downhole and surface facilities. Different works have studied the stability and suggested some solutions to override it, but most of them (such as making the well intelligent) are very expensive and thus they are not applicable to many cases. ...
متن کاملDeveloping a Novel Temperature Model in Gas Lifted Wells to Enhance the Gas Lift Design
In the continuous gas lift operation, compressed gas is injected into the lower section of tubing through annulus. The produced liquid flow rate is a function of gas injection rate and injection depth. All the equations to determine depth of injection assumes constant density for gas based on an average temperature of surface and bottomhole that decreases the accuracy of gas lift design. Also g...
متن کاملPartial Nitritation/anammox and Canon – Nitrogen Removal Systems Followed by Conductivity Measurements
The deammonification process is a new biological promising method for a separate treatment of ammonium-rich digester supernatant. Its application can significantly reduce the nitrogen load in Wastewater Treatment Plants (WWTPs). The method is a two-step process and it can be accomplished in two separate stages (partial nitritation and Anammox) or in a singe one (CANON). Both these systems were ...
متن کاملDevelopment of simultaneous partial nitrification, anammox and denitrification (SNAD) process in a sequential batch reactor.
Simultaneous partial nitrification, anammox and denitrification (SNAD) process was developed in a sequential batch reactor (SBR) and the influence of hydraulic retention time (HRT) on the SNAD process was investigated. Around 96% NH(4)(+)-N removal and 87% COD removal were observed at 9 d HRT. Marginal decreases in the removal efficiencies were observed when the HRT was reduced to 3d or the loa...
