PROJECT DESCRIPTION

In a specific bubble column system, the hydrodynamics depend on operating conditions in terms of pressure and temperature in which high-pressure operations are common in industrial applications. The gas holdup and bubble size determine the bubble surface area that affect the mass-transfer between phases. High pressure enhances surface area while the feedstock is kept as constant. Therefore, there is a need for a CFD model involving a realistic gas-liquid contacting area in a bubble column under high pressure. The objectives of this project are:

A 3D CFD-PBE model is developed to investigate the hydrodynamics in terms of gas holdup, mean bubble size, bubble size distribution and specific surface area

The CFD results are validated with experimental data in terms of specific pressure drop, total gas holdup and mean bubble size

The distributions of gas holdup, bubble size and specific surface area inside bubble column

BENEFITS

CFD model provides an insight into the development of elevated pressure bubble column reactors in a cost- and time-effective way

Gas holdup, bubble size distribution and surface area profiles

Minimum operating pressure or feed stock with maximum bubble surface area
