Our patended Wave Cryogenic and
Refrigeration Technology creates a gas wave system using pressure drop of
process vapor stream. By controling such a gas wave system, several different
engineering goals. For instance, the compressible waves created in the aforesaid
gas wave system can generate a higher temperature effect which makes system
energy easily removed. Meanwhile, an expansion wave system will reduce system
temperature to make refrigeration more effective. The unique feature of this
technology, is that such a system can be implemented without using any moving
part in our device. This feature will significantly increase operation
reliability, reduce the operation and maintenance costs, and enhance the
efficiency of applied industrial systems and processes.
Chokes
and J-T valves control pressure drop and waste all energy by throttling
dissipation due to the simple structure with no moving parts, and expanders can
extract pressure energy by a complex moving structure that results in lower reliability and limit on operating conditions. In contrast to conventional
chokes and expanders currently used in oil & gas industries, the PWECT
products integrate the merits in both devices (pressure controlling
and energy extraction with no moving parts), handling pressure reduction
energy efficient while retaining the simplicity and reliability of its
structure. The operation of PWECT products is illustrated in the
left figure. When a pressurized stream flows through a PWECT
device, pressure drop is used to drive periodic gaseous wave systems rather than
a mechanical part or being throttled through a constrained orifice. The cooling
and heating effects are produced by periodic wave systems (compressible and
rarefaction waves), and heat is removed from pressure drop in order to increase
cooling efficiency even being in the conditions of varying flow states.
Applying pressure energy to
generate refrigeration is a fundamental thermodynamic cycle which have been used
in a broad field of both commercial and residential industries. In summary, WCRT
technology has a broad base of industrial applications and thus variant
marketing potentials.
The potential applications of the CWAT's new technology
covers broad industrial fields in both common and high-technical industries. In
the common industrial area, the potential applications of CWAT's products can be
applied to a variety of processes and systems in common industries as well. In
those where pressure drop is available and cooling or heating effects are
needed, companies and plants, such as oil refinery plants, systems of off-shore
oil and gas extraction, liquefied natural gas (LNG) processes, industrial gases
liquefaction systems can benefit. The marketing goal of CWAT is to provide
quality products to improve the existing systems and production processes.
