Parameters characterising the pulsing flow for cocurrent flow of gas and foaming liquid in a pressurised trickle-bed reactor
نویسندگان
چکیده
The aim of the present work was to experimentally determine the parameters characterizing the pulse flow of liquids through bed i.e. the frequency of pulsation and the velocity of pulses travelling along the bed and next to work out the correlation equations enabling their assessment. The research was carried out in a pressure reactor (pressures up to 2 MPa) having 0.05 m in diameter and being 1.5 m long. Physicochemical properties of the gas and liquid phases were changed in the research and the concentrations of water solutions of aliphatic alcohols were chosen in such a way so that the systems would form foams of various lifetime as a result of their contact with the gas in packing. The experimental data which were obtained as a result of the research were correlated depending on the operational parameters of the reactor and physicochemical properties of gas and liquid phases. The knowledge of the examined in the present work parameters is extremely important to model the operation of a three-phase system in the pulsing flow regime.

Analysis of Foaming Flow Instabilities for Dynamic Liquid Saturation in Trickle Bed Reactor
The effects of different parameters on the hydrodynamics of trickle bed reactors were discussed for Newtonian and non-Newtonian foaming systems. The varying parameters are varying liquid velocities, gas flow velocities and surface tension. The range for gas velocity is particularly large, thanks to the use of dense gas to simulate very high pressure conditions. This data bank has been used to c...
متن کاملEffect of Pulsing on Reaction Outcome in a Gas-Liquid Catalytic Packed-Bed Reactor
There has been continuous interest and fascination with the fluid dynamics of trickle-beds (i.e., cocurrent gas-liquid packed-bed reactors) at least since Weekman and Myers (1964) first proposed a regime map for their operation. Consistent with other flow regime maps before (Baker, 1954; for gas-liquid pipe flow) and since (e.g., Mandhane et al., 1974; for pipe flow), visual observations were u...

Abstract Gas to liquid (GTL) process involves heterogeneous catalytic chemical reactions that convert synthesis gas to hydrocarbons and water vapor. A three phase reactor, called Low temperature Fischer-Tropsch (LTFT) is commonly applied for GTL process. In this reactor the gaseous phase includes the synthesis gas, light hydrocarbons and water vapor, the liquid phase is a mixture of the h...

In this study, a pellet scale model was developed for trickle bed reactor utilizing CFD techniques. Drag coefficients were calculated numerically at different velocities and bulk porosities in the case of single phase flow through the dry bed. The simulation results were then compared with the prediction of Kozeny-Carman (K-C) equation. The results indicated that drag coefficients calculated fr...

The influence of reactor pressure up to 6.0 MPa on the dynamic liquid hold-up in the trickle-flow regime with superficial gas velocities up to 5.2 cm/s has been investigated for water, ethanol and aqueous 40% ethyleneglycol, with nitrogen as the gas phase. Without gas flow, i.e. single-liquid trickle-flow operation, the reactor pressure has no influence on the dynamic liquid hold-up, which can ...
