OPTIMIZACIJA TERMODINAMIČKOG CIKLUSA U PROIZVODNJI GEOTERMALNE ENERGIJE
Description (Dublin Core)
eng
Optimization of geothermal energy production process means the minimization of all energy losses from the reservoir conditions to the user. As the available energy is being utilized mostly in the wellbore and in the surface equipment, process optimization requires scientific access including the extraction technology parameters.Specific energy on the geothermal wellhead is calculated for two possible cases. The first embraces only geothermal water production, while the other takes into account the saturated steam production as well. Each of these working conditions defines unambiguously designed pressure on the wellhead.The steam and water energy ratio, in function of predicted sink temperature for reinjection of geothermal water, points out the possibilities for commercialization of reservoir Velika Ciglena.

Optimizacija procesa proizvodnje geotermalne energije obuhvaća smanjenje svih energetskih gubitaka od ležišnih uvjeta do potrošača. Raspoloživa energija uglavnom se troši u kanalu bušotine i površinskoj opremi, pa optimiziranje cjelokupnog procesa zahtjeva znanstveno-istraživački pristup zasnovan na tehnologiji pridobivanja geotermalnih fluida. Jedinična energija na ušću geotermalne bušotine može se izračunati za dva moguća slučaja. Prvi, uzima u obzir proizvodnju geotermalne vode, dok je u drugom prisutna i zasićena para. Odabran način proizvodnje jednoznačno određuje projektirani tlak na ušću bušotine. Omjer jediničnih energija pare i kapljevine u funkciji pretpostavljenih utisnih temperatura geotermalnog fluida može ukazati na komercijalizaciju ležišta Velika Ciglena.
