The present invention, named SelfReHeating – SRH, is a new configuration of the geothermal power plant, that allows for more efficient – compared to current standards – power generation.
The technology uses a regenerative re-heating process. It consists of using the steam separated at the wellhead through a cyclone separator in a backpressure turbine where it is expanded at a pressure generally higher than atmospheric pressure. The wet steam at the outlet of the backpressure turbine is heated using the liquid separated at the wellhead and sent to a steam turbine for expansion up to the pressure of the condenser. Re-heating increases both the enthalpy drop and the isentropic efficiency of the expansion process.
So, the present geothermal power plant has an unedited configuration that allows to obtain a significant increase in power generation compared to known system with the same boundary conditions.

  • Microplastic filter system for appliances

    Microplastic pollution is becoming an increasing concern for the wellbeing of the marine environment and consequently for human health. Currently attempts to reduce the release of microplastics/microfibers from domestic laundering appliances with micrometric mesh filters or washing bags have proven[...]

  • Producing bioethanol and/or glucose syrups from raw starch

    The invention relates to combinations of novel and efficient glucoamylase and alpha-amylase expressed in industrial Saccharomyces cerevisiae yeast strains for the processing of raw starch into bioethanol. The efficient amylases combinations, tested on a cluster of starchy substrates (raw corn[...]

  • Black soldier fly larvae to treat wastewater on an inert media

    This patent proposes an alternative treatment of waste water rich in biodegradable organic substances through the use of black soldier fly larvae (BSF). Black soldier fly larvae are able to metabolize and stabilize huge amounts of organic matter, transforming it[...]
