Energy saving potential associated with recovering the waste heat of industrial plants in oman

T
he power demand is facing a rapid increase and is starting
to create a burden on Oman due to its unrenewable
main sources of energy. Oman power production is mainly
dependent on crude oil and natural gas (NG), while there
is no much power produced by renewable sources as of
yet. Waste heat recovery nowadays is considered to be
an economic method to increase the overall efficiency
of industrial plants and, thus, to lower fuel demand. The
current study amid at evaluating the energy saving potential
associated with recovering the waste heat by means of
an Organic Rankine Cycle (ORC) in four industrial plants in
Oman. Based on the average cooling water temperature and
optimum dimensionless mass flow rate the maximum energy
saving potential has been achieved at Al Ghubra Power &
Desalination. In terms of fuel consumption’s this equals to
i) saving in crude oil consumption by 70.03 liters/day, and ii)
saving in NG consumption by 68.56 m3/ day. Furthermore,
the cost for the fuel purchased by the plant can be reduced
down to 6.400/day Omani Rial (OR) (crude oil) and 1.600/
day OR (NG). In addition, the cost of the power consumed
in the plant would be decreased by 13.00 OR/day. The lower
energy savings potential occurred at Areej Vegetable Oils &
Derivatives. It has been concluded that the ORC technology
seems to be a practical solution for converting waste heat
into power in Oman for industries of high values of waste
heat temperature and flow rate.
