dc.description.abstract |
Propylene, steam and air are fed at atmospheric pressure to two tubular
reactors in series. In the first, propylene is oxidised to acrolein at
3700C. In the second, the acrolein is almost completely oxidised at
2700C to acrylic acid.
The reactor effluent is partially cooled and then quenched, the acrylic acid
is washed with water and solvent. The solvent is removed overhead in the
solvent separation column and recycled. After removal of light ends, the
acrylic acid is then distilled and removed as an overhead product and sent
to storage. The heavy ends are discarded. |
