Energy losses from the radiant firebox wall of pyrolysis furnaces

The steam cracking unit is highly energy demanding, requiring high-severity pyrolysis furnaces to break the carbon-carbon bonds, as well as high pressure for the purification of its products.

The steam cracking unit is highly energy demanding, requiring high-severity pyrolysis furnaces to break the carbon-carbon bonds, as well as high pressure for the purification of its products. This process means a high compression ratio of the cracked gas compressor and a high frigorific demand for fractionation of products, with close boiling points.1 Since the onset of this technological development, the licensors have been striving to reduce the amount of energy demanded per ton of ethylene produced. Most of the energy required, 70%–80% of the total, is spent on the furnaces. A study of the wall heat loss of the radiant fireboxes was carried out by Braskem at the Camaçari Industrial Compl
