The LCOCC as shown in Figure (C) has some of the same features as just discussed for the CAPEX. Compared to air cooled heat exchangers, the use of Shell and Tube leads to an increase in levelised cost. However, as soon as the discharge temperature is reduced to 35 • C a comparable LCOCC can be achieved. For cases 5-8, the LCOCC generally drops and so does the minimum obtained LCOCC for each case as the discharge temperature is reduced. As seen also from Table the location of the minimum LCOCC shifts to lower and lower liquefaction/pumping pressure as the discharge temperature is reduced.
