International comparison of refinery energy efficiencies
We will make a comparison of the energy performance of refineries in country A
and country B. The total production of refinery products is 54,410 kilotonnes
for country A and 85,100 kilotonnes for country B. The countries, however, have
a different mix of products as shown in mass-% in Table 10.9. The table also
shows the best-practice specific energy consumption (SEC) expressed in GJ
primary energy per tonne of product. The fuel and electricity use of refineries
in both countries (in PJ) is given in The efficiency of electricity production
is 50 per cent for country A, and 40 per cent in country B. The best-practice
efficiency of electricity production is 60 per cent. Make the comparison by
answering the following questions:
