we can start from the simplest possible straight line network shown in this chapter and evolve
from it systematically to reach to better networks from waste heat recovery point of view and
of-course GHG emissions reduction while keeping the easy to operate, clean to maintain and
capital cost objectives satisfied. The details of this new approach and its step-by-step
implementation will be published latter elsewhere.
Pinch technology as a new systematic method for advanced waste heat recovery and heat
integration in industrial facilities emanated in the early seventies during the first oil crisis is
still nowadays the most widely used technique for energy integration in oil industry. It has
been successfully used to systematically address the problems of energy efficiency
optimization and the reduction of energy-based un-desired emissions.
Systematic waste heat recovery in oil and gas industry is very beneficial to plant
operating cost reduction. Aggressive waste heat recovery is an essential approach for in-
process GHG emissions avoidance. GHG and other energy-based undesired by-products
atmospheric emissions, produced during oil and gas separation processes and crude oil
distillation can be reduced significantly through proper application of heat integration
concepts. Every megawatt of heating utilities obtained from process boilers and/or furnaces
that can be saved through efficient waste heat recovery system design and operation means
less greenhouse gas and other harmful NOx and Sox emissions.
Improved heat recovery systems designs while can be attained systematically using Pinch
Technology, it is important to consider it in a step-by-step approach especially for the heat
exchangers network grassroots design modifications and existing plants retrofit to enable the
decision makers selects the right scenario that best fit his/her capital investment budget.
