Industrial integration between refinery processes and glass or metallurgical industries represents a good example of waste heat use across different industries.

This type of integration provides good opportunities for optimum energy use.

The required independence can be achieved with coordination between these industries.

In Saudi Arabia industries are usually located in industrial cities.

This nearby location permits coordination and integration. Moreover, individual industries could maintain their own spare energy sources based on the anticipated and acceptable levels of risk.

Waste heat use can best be used in individual industries. Waste heat boilers (WHB) represent a good example of waste heat use.

Saudi Aramco has, in recent years, started utilising WHBs in many refineries and petroleum facilities.

Sceco has installed combined power generation plants at different locations. These plants primarily use gas turbines with WHB to generate steam that turns a steam turbine for extra power generation.

These WHBs are heated by hot flue gases discharged from gas turbines. WHB saves energy and saves in capital costs. These steam generators cost less than ordinary fired boilers.
