Refineries can save energy using an efficient energy design, such as thermal integration in process units, optimisation of heat exchanger trains, air/flue gas heat exchange in furnaces, waste heat recovery boilers, etc.
Aitesa has successfully carried out a large number of projects from basic engineering or extensions, revamping or supply of new facilities for the petrochemical and refinery sector.
We supply fired heaters and waste heat recovery boilers (furnaces) for particular process in refineries. Furnaces and waste heat recovery boilers, usually reach thermal efficiency of 85%. The incorporation of air preheaters for cooling of flue gas to temperatures near the dewpoint are ever more frequent, achieving up to 92% efficiency.
