[54] A PROCESS FOR INCREASING PROCESS FURNACES ENERGY EFFICIENCY
[57] Abstract: The present invention relates to a process for increasing process furnaces energy efficiency through gas turbine integration by using turbine exhaust gas, wherein a hydrocarbon feed is heated in a furnace, said process comprising the following steps: i) feeding furnace combustion air to the burners of a furnace together with furnace fuel to provide high temperature heat to said furnace; ii) cooling the hydrocarbon feed thus processed by using water from a steam drum under the formation of water vapour; iii) returning the mixture of water and water vapour thus formed to said steam drum; iv) withdrawing of saturated high-pressure steam from said steam drum and feeding said saturated high-pressure steam to a heat recovery unit; v) feeding said turbine exhaust gas to said heat recovery unit for converting said high-pressure steam into super heated high pressure steam.
