Chem
Steam Jet Ejector-Liquid Jet Ejector Combination
Systems
handle small quantities of air and large
quantities of condensable vapours on intermittent or
batch operations. They are low level mounted and
conserve energy with effective scrubbing of outlet
gases.
They are ideal to handle small quantities of
non-condensable gases and large quantities of
condensable vapours on intermittent or batch
processes.
Low level mounted and energy conserving with effective
scrubbing of outlet gases. This offers the advantage
over other systems in producing vacuum and
simultaneously scrubbing entrained gases before
discharging to the atmosphere, making Steam
Jet-Liquid Jet Ejector Combination Systems an
ideal selection for contaminated and/or corrosive
applications.
They are available in multi-element form as a central
vacuum source on multi-purpose process applications.
Steam Jet-Liquid Jet Ejectors are generally used to
create vacuum upto 759 mm of Hg in medium size process
vessels. They are simple in construction, operation
and maintenance. The system is more suitable where low
capital investment is preferred. It is usually used
for batch plant applications requiring coarse vacuum
and low level installations.
With the liquid recirculating pump being the
only moving part the Liquid Jet Ejector System is
simple to maintain and very reliable to operate. The
Liquid Jet alone can pull vacuum upto 710 mm of
Hg by using water at ambient temperature, as motive
medium. Steam Jet-Liquid Jet combination can further
enhance the vacuum upto 759 mm of Hg depending upon
the number of stages of steam ejectors, backed up
liquid jet ejectors. Chem Combination Systems
incorporate single or two stage steam ejectors with
liquid jet ejector.
Materials of Construction
Steam Jet-Liquid Jet combinations systems are
available in Carbon Steel, SS 304, SS 316, SS 316L,
