Abstract

It is necessary to create large-capacity LNG-units for natural gas peaks consumption shaving and also to expand liquefied natural gas (LNG) marketing. It is proposed to create such natural gas liquefaction units with the use of outer nitrogen cryogenic thermodynamic cycles. It is necessary to use turboexpander-compressor sets (TECS) in them for maximizing cycles efficiency. Different technological schemes of LNG-units including nitrogen cryogenic units with TECS from one to four have been examined. Data about preferable capacity range and expected specific power consumption of produсed LNG-units depending on their schemes and the amount of TECS has been stated. It is marked that developed LNG-units are less effective in specific power consumption than units that include more complex structure, for example, cascade schemes or multicomponent work substances.
