Abstract
Gas-liquid separators often encounter the challenge of liquid carry-over, where small liquid droplets become entrained in the produced gas stream. This phenomenon can lead to foaming and reduced capacity in downstream absorption processes, as observed in Iraq’s Khor Mor gas-condensate processing plant. To assess whether liquid carry-over contributes to the foaming issue in the sweetening tower, this study analyzed the liquid droplet size distribution in the gas phase and the gas/liquid separation efficiency of the upstream Alpha, Bravo #1, Bravo #2, and Charlee separators feeding the tower. The analysis was conducted by using the industry-standard process software, Horizontal Vessel and ProSeparator correlations within Aspen HYSYS v.14. The study revealed that Alpha, Bravo #1, and Bravo #2 separators were unable to eliminate all liquid droplets within the specified size, failing to achieve the required efficiency. In response, the study proposes a vertical scrubber design with a standard mesh mist extractor, applying the Arnold–Stewart semi-empirical procedure. The design demonstrated a gas/liquid separation efficiency of 99% under current and future conditions. These findings suggest that the proposed design can serve as an optimal solution to control liquid carry-over, maintain high gas/liquid separation efficiency, and prevent foaming, even with an increase in the vessel inlet flow rate over time.
期刊介绍：
Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas.
Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
