1. Hydrodynamics of an external-loop airlift reactor with inserted membrane
Abstract The objective of this study was to investigate the hydrodynamics of an external-loop airlift membrane reactor (ELAMR). The ELAMR was operated in two modes: without (mode A) and with bubbles in the downcomer (mode B), depending on the liquid level in the gas separator. The influence of the gas distributor’s geometry and various alcohol solutions on

2. NUMERICAL PREDICTION OF BUBBLE SIZE AND INTERFACIAL AREA CONCENTRATION IN THE LIQUID BATH OF AN ENTRAINED-FLOW COAL GASIFIER
Abstract A CFD-ABND coupling model was used to study the flow characteristic of gas-liquid two-phase flow in the process of gas passing through the liquid bath of a water-coal-slurry entrained-flow gasifier. In this model, an average bubble number density (ABND) approach was employed and merged with the two-fluid model. A two-phase version of the RNG k-ε tu

11. A study of paint sludge deactivation by pyrolysis reactions
The production of large quantities of paint sludge is a serious environmental problem. This work evaluates the use of pyrolysis reaction as a process for deactivating paint sludge that generates a combustible gas phase, a solvent liquid phase and an inert solid phase. These wastes were classified into three types: water-based solvent (latex resin) and solven
