Abstract

A method for removing formaldehyde from a blend of partially oxygenated hydrocarbons is provided. The method including a step of reacting a hydrocarbon-containing gas with an oxygen-containing gas in a reaction vessel to form first product blend. The first product blend includes a blend of partially oxygenated compounds that include formaldehyde. The blend of partially oxygenated compounds is provided to a reactive scrubbing station where it is contacted with a reactive scrubbing liquid to form a reactive liquid-formaldehyde compound. The reactive liquid-formaldehyde compound is then removed from the first blend of partially reactive compounds.

Dependent claims

A method for removing formaldehyde from partially oxygenated compounds, the method comprising:

a) reacting an hydrocarbon-containing gas with an oxygen-containing gas in a reactor vessel to form first product blend, the first product blend including a blend of partially oxygenated compounds that include formaldehyde;
b) providing the blend of partially oxygenated compounds to a reactive scrubber station;
and
c) contacting the blend of partially oxygenated compounds that includes formaldehyde with a reactive scrubbing liquid at the reactive scrubbing station to form a reactive liquid-formaldehyde compound;
and
d) removing the reactive liquid-formaldehyde compound from the first blend of partially reactive compounds from a first product stream that is depleted of formaldehyde.
