| Zusammenfassung: | The invention discloses a novel styrene waste gas treatment process and device, and relates to the technical field of styrene waste gas treatment, and the technical scheme is that the novel styrene waste gas treatment process comprises the following steps: S1, introducing low-concentration styrene waste gas into a styrene conversion device, and converting the low-concentration styrene waste gas into high-concentration styrene gas; s2, introducing the obtained high-concentration styrene gas and ozone into a catalyst adsorption tower, and reacting to obtain styrene oxide; s3, adsorbing the obtained styrene oxide by using an organic absorbent; and S4, recovering the saturated organic absorbent, distilling and purifying to obtain phenylacetaldehyde. The styrene waste gas collection device has the beneficial effects that the existing unstable styrene waste gas working condition is converted into stable styrene gas through the styrene conversion device, and the uncertainty of styrene waste gas collection caused by |
