Abstract

Fremgangsmåte for energigenerering basert på gassformige drivstoff og en kombinert nitrogenfri termisk kretsprosess med gass (GT) og damp (ST) turbiner, der arbeidsmediet for GT er CO2 og damp dannet ved forbrenning av et hvilket som helst gassformig drivstoff med oksygen i GT forbrenningskammeret under samtidig mating av en delstrøm av komprimert røykgass fra dampgeneratoren ved bruk av GT eksos for dampproduksjon, hvilket damp genererer effekt i en ST. Resten av røykgassen fra generatoren blir brukt for varmtvannsproduksjon i en varmeutvinningsenhet HRU, der varmtvannet delvis blir brukt for fukting av røykgassen før komprimering, for fødevann etc. Røykgassen fra HRU'en er fuktig CO2, som kan bli gitt væskeform og brukt for EOR, for kjemikalier og for dumping i havene etc. Fremgangsmåten netto virknings- grad omfatter 02 generering omfattende O2-generering er 60%; nettovirkningsgrad, også omfattende CO2 væskegjøring, er 58%.Method of energy generation based on gaseous fuels and a combined nitrogen-free thermal circuit process with gas (GT) and steam (ST) turbines, the working medium of GT being CO2 and steam formed by combustion of any gaseous fuel with oxygen in the GT combustion chamber during simultaneous feeding a partial stream of compressed flue gas from the steam generator using GT exhaust for steam production, which steam generates power in an ST. The rest of the flue gas from the generator is used for hot water production in a heat recovery unit HRU, where the hot water is partially used for wetting the flue gas before compression, for feed water etc. The flue gas from the HRU is moist CO2, which can be given liquid form and used for EOR, for chemicals and for dumping in the oceans etc. The net efficiency comprises 02 generation comprising O2 generation is 60%; the net efficiency, including extensive CO2 liquefaction, is 58%.
