Abstract

Przedmiotem zgłoszenia jest sposób regazyfikacji ciekłego gazu ziemnego, w którym gaz ziemny przeprowadza się w stan gazowy w procesie okresowym w odparowalniku wysokociśnieniowym. Proces regazyfikacji prowadzi się w zamkniętej komorze odparowalnika (102) o stałej objętości (204), przy czym w pierwszym etapie prowadzi się przemianę fazową ciecz - gaz, w której ciekły gaz ziemny ogrzewa się do temperatury krytycznej za pomocą ciepła o niższej jakości w postaci czynnika grzewczego o temperaturze w zakresie od -30°C do +50°C. Następnie gaz w postaci lotnej ogrzewa się do temperatury powyżej temperatury krytycznej za pomocą ciepła o wyższej jakości w postaci czynnika grzewczego o temperaturze w zakresie od 50°C do 250°C do osiągnięcia ciśnienia gazu w komorze (204) wynoszącego co najmniej 7 MPa. Następnie otwiera się wylot komory odparowalnika wysokociśnieniowego (206) połączony ze zbiornikiem magazynowym (103) o niższym ciśnieniu niż ciśnienie gazu w zbiorniku (204) i napełnia się zbiornik magazynowy (103) gazem ziemnym w wyniku ekspansji gazu ziemnego do zbiornika (103) w wyniku różnicy ciśnień, po czym zamyka się zbiornik magazynowy (103) i ogrzewa się gaz w zbiorniku magazynowym (103) ciepłem pochodzącym ze spalania biomasy (104) zwiększając w wyniku ogrzewania ciśnienie gazu w zbiorniku magazynowym (103), po czym gaz ziemny rozpręża się (105), ogrzewa (106, 107) i wprowadza do rurociągu (108). Przedmiotem zgłoszenia jest także system do regazyfikacji skroplonego gazu ziemnego.The subject of the application is a regasification method of liquid natural gas in which natural gas is converted into gaseous state in a batch process in a high-pressure evaporator. The regasification process is carried out in a closed vaporizer chamber (102) with a constant volume (204), with a first phase liquid-gas phase transformation in which the liquid natural gas is heated to a critical temperature by means of lower quality heat as a factor heating with a temperature in the range from -30 ° C to + 50 ° C. Then, the gas in volatile form is heated to a temperature above the critical temperature with the help of higher quality heat in the form of a heating medium at a temperature in the range from 50 ° C to 250 ° C until the gas pressure in the chamber (204) is at least 7 MPa. Next, the outlet of the high-pressure vaporizer chamber (206) connected to the storage tank (103) with a lower pressure than the gas pressure in the tank (204) opens and the storage tank (103) is filled with natural gas as a result of expansion of natural gas into the tank (103) as a result pressure difference, then the storage tank (103) is closed and the gas in the storage tank (103) is heated with heat from biomass combustion (104) increasing the gas pressure in the storage tank (103) as a result of heating, after which the natural gas expands ( 105), heats (106, 107) and enters the pipeline (108). The subject of the notification is also a regasification system for liquefied natural gas.
