I NTRODUCTION
In process industries the main source of waste heat is associated with hot utilities; that
include furnaces, steam boilers, gas turbines and diesel engines.
Energy efficiency optimization not only keeps operating cost under control and conserve
depleted resources but also reduces GHG emissions.
Oil and gas industry consists of very energy intensive processes. Oil and gas separation;
crude atmospheric and vacuum distillation; Naphtha and Diesel hydro-treating and gas oil and
Naphtha reforming, are only some examples.
In the oil and gas business, energy cost is a major element in any facility operating cost.
It usually comes before maintenance cost and sometimes even labor cost. Implementation of a
