“…and increasing the gas flow rate from 1.5 to 9 𝑚 3 ℎ , slug flow occurs as shown in Figure 6-E. Considering that the slug flow regime has been observed in the flow pipeline, it is important to investigate possible control methods in the laboratory pilot to manage this regime [9,12].…”

In the oil industry, multiphase separators are of paramount importance in oil production, as they have a significant impact on overall oil production capacity. However, the occurrence of slug flow, which is characterized by undesirable behavior, can cause extensive damage to the surface separator and pipelines. Consequently, the development of intelligent separators and the implementation of effective flow regime control mechanisms are crucial. To address this issue, our research aimed to investigate the behavior of different flow regimes entering the separator and evaluate the intelligence system of the separator. Initially, we constructed a laboratory-scale multiphase flow loop as a platform to examine various flow regimes entering the separator. Through laboratory tests employing a PID controller, we collected data concerning the liquid level, gas pressure, input flow rate, and control signals of the separator. Subsequently, we accurately modeled the laboratory system and conducted simulations in a multiple-input-multiple-output mode with model predictive control. After ensuring the effective operation of the laboratory smart control system, we integrated its control model with a production system containing a real fractured reservoir. The results demonstrated that the implementation of the smart integrated production system could enhance oil production by approximately 53% over a 20-year simulation period.

“…What’s more, Liu et al (2018a, 2018b) explored the thermal stratification in the liquid hydrogen tank by setting a series of gravity values. Lee et al (2018) discussed the influence of the inlet slug flow on the horizontal gas-liquid separator. Some scholars (Zheng et al , 2018; Liu et al , 2018a, 2018b) had done a research about liquid sloshing in a 2D tank by installing different kinds of complex baffles inside the container, and they found that the complex baffles could play an important role in reducing the dynamic pressure.…”

Purpose The purpose of this paper is to analyze the liquid sloshing behaviors in two-dimensional tanks with various porous baffles under the external excitation. Design/methodology/approach Adopting the finite element method (FEM) and control variable method to study the impacts of the height, length, number, location, shape, porous-effect parameter of the porous baffle, the external load frequency and the shape of the tank on the liquid sloshing response. Findings The amplitude of the free surface can be reduced effectively when the baffle opening is appropriate. The anti-sway ability of the system increases in pace with the baffle’s height growing. Under the same conditions, the shapes of the baffles have an important effect on improving the anti-sway ability of the system. Originality/value As there exist the differences of the velocity potential between each side of the porous baffle, which means that there are two different velocity potentials at a point on the porous baffle, the conventional finite element modeling technologies are not suitable to be applied here. To deal with this problem, the points on the porous baffle are regarded as two nodes with the same coordinate to model and calculate.

Slug frequency, the number of liquid slugs passing through a point per unit of time, is an intrinsic parameter that is used to characterize multiphase slug flows in pipes. In this review we discuss practical aspects of slug frequency for industrial purposes from an examination of published literature and available experimental data. The review shows that slug frequency appears to play a key role in the modelling of intermittent flow using 1‐D mechanistic slug models and 3‐D computational fluid dynamics tools. In addition, various global parameters and phenomena used to design, optimize, and control industrial pipelines are directly impacted by slug frequency. This manuscript highlights the importance of slug frequency not only for petroleum engineering but also for chemical, nuclear, and mechanical engineering.
