The current research deals with the thermodynamic and economic assessments of an integrated thermoelectric generator system with the liquefied natural gas production process. The main aim of the present work is investigation the influence of the thermoelectric generators modules location, in a liquefied natural gas production cycle, on the thermodynamic and economic criteria. A Matlab code has been developed to assess the integrated system performance. Suggested integrated systems include adding the thermoelectric generators between the condensers and evaporators (Case I) and adding the thermoelectric generators between the condensers and ambient air (Case II). The results show that the position of the thermoelectric generators considerably influences the system performance. The results indicates that in Case I (with adding thermoelectric generators between condenser and evaporator) the system …
