HydrodealkylationUpgrading fuel blending stock to high-value petrochemical intermediates
As a leading global industrial gases and engineering company, Linde has a long history in the production and supply of acetylene gas, mainly for welding applications and as a chemical intermediate. Today we gladly share our know-how with our customers by providing licenses and designs for our state-of-the-art acetylene recovery technology worldwide.
In the 1960s, Linde was the first company to implement the continuous recovery of acetylene in a commercial steam cracker. Since then, Linde continually refined the design to meet the evolving demands of the market. Building on this track record and proven expertise, Linde now offers a range of benefits
Backed by 45 years of successful operation in numerous commercial plants, Linde Engineering offers a thermal HydroDeAlkylation (HDA) process for the production of benzene from refinery and petrochemical streams.
This non-catalytic process is flexible towards a wide variety of feedstocks including toluene, xylenes, C9 aromatics, hydrogenated pyrolysis gasoline and reformate to produce high purity benzene with compelling yields.
In addition, it readily tolerates impurities of substances such as hydrogen sulfide (H2S), carbon monoxide (CO), carbon dioxide (CO2) and ammonia (NH3).
