CO2 Capture from Oil Refinery Process Heaters Through Oxyfuel Combustion

Techno-economic performance and challenges of applying CO2 capture in the industry: A case study of five industrial plants

“…Also, furnaces differ from boilers in a number of respects: a wider range of furnace designs and different techniques used to construct them, often results in greater air in-leakage (1); hydrocarbons are often present in furnace tubes, presenting additional hazards (2); usually, burner types are used without automatic control of air/fuel ratio and draft. Retrofitting of furnaces may, therefore, raise operational issues not encountered with boilers (Kuramochi et al, 2012;Wilkinson et al, 2003). • Metallurgical limitations of boiler and furnace walls due to higher oxyfuel combustion temperatures do not seem to be a problem as flue gases can be looped back to the inlet of the process unit to simulate air combustion conditions (Scheffknecht et al, 2011).…”

“…Furthermore, although several studies state that retrofitting industrial boilers and furnaces with CO 2 capture equipment is technically feasible (Allam et al, 2005a,b;IEA GHG, 2000;Wilkinson et al, 2003), no overview exists of additional challenges which may arise during implementation and operation of CO 2 capture equipment at industrial plants. It may, for example, be challenging to install flue gas ducting and CO 2 capture equipment on an already congested industrial site (Hurst and Walker, 2005;IEA GHG, 2008;van Straelen et al, 2009).…”

Effect of CO2 capture on the emissions of air pollutants from industrial processes

“…At the refineries, CO 2 is emitted from various sources such as furnaces and heaters, onsite heat and power plants (including CHP plants), and catalytic crackers. Onsite generation of electricity and heat is responsible for the bulk of the CO 2 emissions in petroleum refineries (Wilkinson et al, 2003). In particular, furnaces and boilers account for 65% of CO 2 emissions from refineries worldwide (IEA GHG, 1999).…”

Heat supply alternatives for CO2 capture in the process industry

“…To date, most work on CO 2 capture in the petrochemical and petroleum industry has been focusing on two capture processes; post-combustion and oxyfuel combustion (see e.g. de Mello et al, 2009;Dolf, 2003;Ho et al, 2011;Kuramochi et al, 2010Kuramochi et al, , 2012Miracca et al, 2009;Simmonds et al, 2003;van Straelen et al, 2010;Wilkinson et al, 2003). The advantage with the oxy-fuel combustion technology is that a clean CO 2 stream is generated and that the process has a lower energy demand.…”
