“…Ada banyak metode untuk melakukan proses pemisahan gas antara lain absorpsi, adsorpsi, kriogenik, membran dan yang terbaru yaitu pemisahan supersonik (Cao & Bian, 2019). Metode absorpsi dan adsorpsi membutuhkan proses yang kompleks dan menggunakan bahan kimia yang bisa berdampak pada lingkungan.…”

“…Axial valves (Weevers, 1982;Peterman and Keithahn, 1987;Esveldt, 2012;Preston, 2018;Canjuga, 2019;Ziegler, 2019) provide a straight-line flow of fluid with minimal resistance when opened. Note that this type of valve is actively used in controlling flows, both liquid (Weevers, 1982;Peterman and Keithahn, 1987;Esveldt, 2012;Preston, 2018;Canjuga, 2019;Ziegler, 2019;Emerson, 2020;Flowserve, 2020;Mokveld, 2020;Rust, 2020;Talis, 2020) and gaseous media (Bian et al, 2019a,b;Cao and Bian, 2019;Emerson, 2020;Flowserve, 2020;Mokveld, 2020;Rust, 2020;Talis, 2020). Moreover, the system "perforated separator-internal piston" (Weevers, 1982;Peterman and Keithahn, 1987;Esveldt, 2012;Preston, 2018;Canjuga, 2019), in particular, with one (Peterman and Keithahn, 1987;Esveldt, 2012;Preston, 2018;Canjuga, 2019) or several throttle stages (Weevers, 1982) of throttling, when the internal piston, as a rule, is most widely used as a locking and regulating element.…”

“…However, this design (Weevers, 1982) turned out to be quite complex and did not solve the problem of cavitation at small stages of valve opening. Note that the active use of various nozzle designs and the principle of swirling the working fluid flow are observed in Mokveld products (Mokveld, 2020), and similar technical solutions are used for gas liquefaction (Bian et al, 2019a,b;Cao and Bian, 2019). In particular, the analysis of design features of axial valves was performed in Lebedev et al (2016Lebedev et al ( , 2017a.…”

“…Regarding the methods for calculating the effective ranges of the design parameters of control valves, two approaches are most widespread: analytical estimation (Arzumanov, 1971(Arzumanov, , 1985Blagov, 1990) using the Pi-Buckingham theorem (Buckingham, 1915;Misic et al, 2010) or numerical modeling for gaseous (Bian et al, 2019a,b;Cao and Bian, 2019) and liquid (Qu et al, 2015;Hou et al, 2017;Rudolf et al, 2017;Qiu et al, 2019;Tang et al, 2019) environments using ready-made software products (Ansys Inc, 2013. Moreover, the first approach requires a wide experimental base, and the second requires a long adaptation of the software product to the main factors influencing the course of the studied processes, including cavitation (Knapp et al, 1970;Franc and Michel, 2005;Xu et al, 2015), in a specific design.…”

The purpose of the work is to develop an analytical method for calculating the effective ranges of structural parameters of the throttle part of the axial valve with the external location of the locking shell based on the proposed stochastic models of bubble formation at the initial stage of hydrodynamic cavitation. In contrast to the well-known engineering methods for choosing the conditional bore diameter for the designed control device constructed using the Pi-Buckingham theorem, this calculation method relies not only on gyrodynamic similarity criteria, but also on functional dependences for the laws of distribution of cavitation bubbles according to various characteristics (specific size bubbles, the degree of opening of the node "separator-external locking shell"). This takes into account a wide range of design and operating parameters, including the required valve capacity, as well as the physical and mechanical characteristics of the working medium. A block diagram of the calculation of the node "separator-external locking shell" for the specified axial valve is proposed. The influence of a set of design parameters for the "separator-external locking shell" assembly from the rational ranges of their variation obtained using the proposed analytical calculation algorithm on the size of cavitation bubbles is investigated. It has been established that when using the latest results in comparison with the values of parameters from irrational ranges of change, there is a tendency to reduce the ensemble average value of the diameter of the cavitation bubble by 1.95 times, when switching to a mode from 20% of the degree of separation of the separator to 80% of the opening of the throttle holes, the nominal valve capacity increases by 10.7 times. The results obtained illustrate the possibility of preventing an increase in the intensity of formation of cavities in the flow part of the control device already at the initial stage of the occurrence of cavitation.

“…Xiao et al (2017) pointed out that the temperature decreased when the wet natural gas flows through the Laval nozzle. Some researchers (Bian et al 2018b;Cao et al 2019a) proposed that under the same ratio of inlet pressure to outlet pressure, the temperature of the gas in a Laval nozzle drops significantly more than that of other throttling devices. Hou et al (2018) showed that orifice thickness has little influence on the throttling effect and that the orifice diameter should be designed to be as small as possible.…”

Wet natural gas widely exists in the natural gas industry, and the selection of throttling devices plays an important role in wet natural gas transportation. In order to study the flow field characteristics of different throttling devices in wet natural gas pipelines, a set of Laval nozzles, orifice plates, and plate valves have been designed. The standard k-ε model was selected for numerical simulation. By changing inlet pressure, inlet temperature or volume fraction of water-liquid, the pressure field and temperature fields of different throttling devices were obtained, and the influence of the presence of a shockwave on the flow fields of the throttling devices was analyzed. Different throttling devices have significantly different operating characteristics. Therefore, appropriate throttling devices should be selected in different conditions in order to control the pressure of wet natural gas transportation and reduce gas hydrate formation. The present simulation results show that under identical conditions, the throat pressure and temperature of the Laval nozzle are the lowest, the throat pressure of the orifice plate is the highest, and the throat temperature of the plate valve is the highest.
