Production of liquid biogas, LBG, with cryogenic and conventional upgrading technology - Description of systems and evaluations of energy balances
The aim of this master thesis is to evaluate energy balances for the production of liquid biogas, LBG.LBG can be produced in two main ways and these are by means; cryogenic upgrading technology andconventional technologies connected with a small-scale liquefaction plant. A third alternative is to injectbiogas into the gas grid and then liquefy a part-flow at a pressure letdown station.The cryogeni
