“…The geometry of a T-junction is so far the most influential parameter on the phase separation efficiency. Even though the majority of literature is based on the geometry of T-junction, there is still room to work around the parameters because of the seriousness of the issue [11,19,31,32].…”

Whenever T-junctions are used in chemical processes and petroleum industries for two-phase separation, a maldistribution of phases is observed between outlets of the junction. Currently, the regular T-junctions are utilized in the industry due to which equipment downstream faces high liquid carryovers. Unfortunately, downstream equipment is not capable of handling high liquid carryovers and they trip frequently, consequently. This review manuscript summarizes the effect of different factors that influence phase separation in the T-junction. This article refers to the geometrical parameters, phase superficial velocity flow regimes encounter during the separation process, and different side arm modifications. This article is a contribution to this field as it summarizes and concludes all these factors comprehensively, to give a verdict on ways to improve phase separation. It is also recommended that the effect of side arm modifications or combinations must be explored for further understanding.

Nowadays, the application of advanced technologies in modern production systems is the main trend of development and technological progress in many industrial sectors. It is due to the still growing trends of energy-saving and production quality enhancement. Wherever in the production process the phase mixture is transported and it is not optimal or not economic, there is a need to develop a system which would be able to prevent any construction disaster, unexpected production line stopping or situation where for reasons of bad flow parameters, the final product is defective. This paper studies various sensors, measurement techniques and computer methods for signal processing and analysis to diagnose and control two-phase flows. Due to the possibility that the invasive measurement disturbs the process and changes it parameters and behavior especially in the location just after the measurement point and simultaneously does not provide any information about these changes it is unreliable for the diagnosis or control. Therefore, the non-invasive techniques commonly used for measurement of flows parameters are described. Depending on the industrial demands many of applications examples for non-invasive two-phase flows measurement and monitoring are given. This description for identifying the flow parameters is divided into features categories of this phenomena as void fraction distribution, velocity profile and flow regime. However, from these methods the high accuracy and short processing time is expected. The continued observation and monitoring of the process abnormalities can provide valuable information about its dynamic state and allow for real-time and automatic monitoring and control. Therefore, the development of advanced process control is one of the most important challenges to keep the flow regime on the given level and for instant and long-term energy saving, quality improvement.

Two-phase flow is the simplest form of multi-phase flow or multi-component flow. Inside a two-phase flow, two phases or components flow simultaneously. The most important thing to ensure is not to let a flow pattern occur that can increase the flow pressure to increase very extremely so that it will damage the piping system or channel, both on the mini, small channels, and large channels. The flow pattern’s main parameters include superficial velocity, fluid density, and viscosity. Therefore, it is crucial to examine how influential these parameters are in forming flow patterns. This experimental study used an acrylic pipe 160 mm long with a diameter of 1.6 mm in a horizontal position. The liquid solution used is a water-coconut oil emulsion of 350 mg/dl and a water-oil emulsion of 500 mg/dl. The superficial velocity of the gas (JG) = 0.083 m/s - 76.604 m/s and the superficial velocity of the liquid (JL) = 0.041 m/s - 4.145 m/s. The resulting Flow Pattern is Plug, Slug Annular, Annular, and churn. Changes in the mixture of water emulsions and coconut oil have little effect on the flow pattern of a plug, slug annular, and annular and significantly affect the flow pattern of churn. This significant influence occurs because the variation in the mixture of water and oil emulsions greatly affects the difference in viscosity of liquids, namely 130.00 Cp and 161.66 Cp, thus affecting the type of flow pattern. In this study, a bubbly flow pattern was not found. This case was due to the absence of laminar to turbulent transitions because higher oil concentrations resulted in lower Reynolds values.
