Fired heaters and waste heat recovery units
Selas Linde North America (SLNA) has more than seventy years of experience designing and building fired heaters and furnaces and has supplied more than 3,000 worldwide.
SLNA is acknowledged as one of the leading suppliers of ethylene dichloride (EDC) cracking furnaces, having supplied the majority of EDC furnaces worldwide since our first installation in 1959. We have equipment installations and experience with virtually every major vinyl chloride monomer (VCM) processor including but not limited to: Oxy Vinyls, Ineos Vinyls, Solvay, PPG, Dow, Shell, ICI and Mitsui. Utilization of our unique offset convection section with a dynamic radiant tube support system offers certain design features that improve performance, operation, maintenance, tube life and runtime. We have 80+ EDC furnaces installed worldwide with capacities up to 225 kta.
In addition to EDC, SLNA has provided specialty and refinery heaters for an array of specialty chemical processes and virtually any refinery requirement. Our reference database is extensive in application and large in number. Our wide range of specialty and refinery fired heaters includes the following applications:
- Reactor feed heaters and steam superheaters for styrene monomer facilities
- Thermal cracking of acetic acid to produce ketene and acetic anhydride
- Benzene to biphenyl
- Heating natural gas while vaporizing and superheating sulfur to combine into carbon bisulfide (CS2)
- Superheating oxygen and/or titanium tetrachloride (TiCl4)for titanium dioxide (TiO 2) facilities
- Crude heating
- Vacuum distillation
- Steam superheating
- CO Boilers
Direct reduction of iron (DRI) processes use reducing gas to convert iron ore (pellet/lump) into metallic iron. The reducing gas is generated directly in a natural external gas/steam reformer from gasification of fossils such as coal or from coke oven gas (COG).
SLNA supplies DRI heaters for all kinds of direct reduction iron (DRI) technologies including ENERGIRON (HYL, DANIELI), COREX-MIDREX and CIRCORED.
