Cryowave Technology and Publications

Our patented Wave Cryogenic and Refrigeration Technology create a gas waves system using pressure drop of process vapor stream. By controlling such a gas waves system, several different engineering goals. For instance, the compressible waves created in the aforesaid gas wave system can generate a higher temperature effect that 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 that has 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 cover 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 offshore 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.
