Performance of a novel confined plunging jet reactor incorporating an annular air lift column
thesis
posted on 2018-11-21, 09:57 authored by Bader Al-AnziIn this thesis experiments were carried out to achieve the desired objectives of
investigating the performance of a novel confined plunging liquid jet reactor
incorporating an annular riser. Air entrainment measurements were made using
different confining tubes and the induced flow in the annular tube surrounding the
confining tube was measured. The oxygen transfer achieved was also determined and
compared with other contacting devices. A literature survey regarding the theoretical
and experimental work relevant to unconfined and confined systems, air-lift column
and mass transfer has been carried out. The experiments include novel equipment
utilized to make the lab measurements including air entrainment and novel air-lift
column measurements. The theoretical part of the thesis contains a new model
derivation to predict the liquid flow rate in the annular riser, which compares well
with the experimental measurements.
The objective of the first pilot plant experiments is to make air entrainment rate
measurements and to investigate the effect of main variables on air entrainment rate.
This enables the research to develop a better understanding of the Confined Plunging
Liquid Jet Reactor (CPLJR) as an aeration process, of interest of Kuwait Institute for
Scientific Research (KISR) and Kuwait, that can be used in various systems such as
wastewater treatment as an aerobic activated sludge process, fermentation and gas–liquid
reactions. [Continues.]
