Trigeneration

  • CCES and Trigeneration Technologies

    Controlled Cavitation Energy System or CCES is a powerful, efficient and economic source of steam. Trigeneration involves the combined use of heat for power generation, heating and absorption cooling. The continuous generation of steam from a CCES based system can directly power generators or reciprocating steam engines for electric power generation. Exhaust steam can be employed in thermal desalination and further used in culinary food processing. The low temperature and pressure exhaust steam from the generator can be employed as the heating component as part of the desorption cycle of an absorption cooling plant.

    It is estimated that 40% of the world's population lives within a short distance (100 kilometers) of the coast. Many of these communities are in arid regions where fresh potable water is in short supply. Only 3% of the world's water is fresh water, and two-thirds of that is located in isolated areas in glaciers or in the arctic or otherwise unavailable for human use.

    This is especially true in coastal regions of the Indian Ocean, Persian Gulf and Southern Pacific where not only fresh water is in short supply, but electricity and food resources. The economies of coastal communities are often fisheries based. With economic non-polluting electricity, refrigeration and steam for cooking and sanitization the welfare and economies of such communities should be substantially improved.

    A small scale CCES system comprised of a compact boiler-less steam generator will form the core of a tri-generation system. When situated near a source of seawater the CCES unit can drive a 100 KW generator, power a thermal vapor source for either Multi-Stage Flash Distillation (MSF) or Multi-Effect Distillation (MED) units or membrane type desalinator, absorption cooler and steam food processing (fish cannery) system. The entire unit could be packaged inside a 20 - 40 steel shipping container and delivered to remote sites by ship or truck.

    The CCES system normally uses pure filtered fresh water during operation in a closed thermodynamic cycle, where the exhaust steam is condensed and cycled back into a feedwater pump supplying the high pressure compressor.

    During the course of our research and development CCES Engineers observed some remarkable effects. When salt water is injected into the impact chamber at high pressures and high temperatures molecular separation of the oxygen and hydrogen creates a plasma which upon cooling recombines and explodes. The extremely high temperatures required to effect molecular separation in water result from cavitation bubble collapse at the impact chamber surface. This process is documented in an associated white paper authored by CCESand other research engoineers (https://news.illinois.edu/view/6367/207368).

    The above video clearly demonstrates the amount of energy released during this process. CCES presently has performed the preliminary engineering work on a highly scalable system that utilizes this intriguing effect. The saltwater variation of the CCES system will operate in an open circuit mode, pulling in seawater through a filtration apparatus, compressing the water and injecting it into the impact chamber array, numerically scaled to the level of steam required. Explosive output from the system in the form of heat and shock wave energy is channeled through a generator. Effluent and brine concentrate are channeled off for collection and reprocessing and the waste heat used to power the distillation unit and absorption chiller.
