Project title: ISOTHERMAL COMPRESSOR/EXPANDER

Company name : *** ISOCOMP LTD.

TECHNOLOGICAL FIELD
Compressors

KEY WORDS
Isothermal
Compressor/Expander, Liquid Sealed Vane Oscillator

PROJECT SUMMARY
A compressor/expander, which can attain a high pressure-ratio,
without changing the gas temperature, has been developed.
Conventional compressors must use many inter-coolers to approach
this condition. Isothermal compression is associated with the
least pumping work for a given pressurization duty. The
respective isothermal processes directly result in the heat of
compression/expansion equaling the compression/expansion work.
This heat can be removed/supplied at a temperature very close to
the environmental temperature.

TECHNOLOGY
The novel compressor/expander makes use of Direct Contact Heat
Exchange (DCHX) between the gas being handled and a heat transfer
liquid. The liquid having an overwhelmingly greater heat capacity
than that of the gas causes the gas to assume the temperature of
the liquid. It is separated from the gas and thermally
conditioned in an external heat exchanger and can be very closely
coupled to the ultimate heat sink/source.

The compressor/expander is based on the invention of Liquid
Sealed Vane
Oscillators (patents obtained in Israel, USA and Germany). These
are double-acting positive displacement devices providing a
special configuration for outfitting with suction/delivery valves
and liquid injection means. Various heat transfer liquids can be
employed to cover operating temperatures from 20øC to 390øC, e.g.
water-glycol solutions in the low end and synthetic oils in the
high end. Any gas can be handled which does not chemically react
with the heat transfer liquid.

ADVANTAGES:
* High net isothermal efficiency (85% projected) available at
high pressure ratios (up to 25 per stage), results into operating
cost savings of up to 50 %.
* The handled gas is washed by the liquid and can exit the
compressor cleaner and dryer than it entered, reducing the need
for miscellaneous supporting equipment.
* The extremely high power density (input shaft power/ machine
volume) and simplicity of design, allow for competitive pricing.
* Small footprint.
* Lower maintenance expenses.

PROJECT STATUS
The project has graduated the incubator.
An earlier prototype has been constructed, which demonstrates the
technological feasibility of the design. Two additional
prototypes are being manufactured.
