Methods and systems for removing volatile organic compounds from spent air are provided. The method can include oxidizing cumene in the presence of an oxidant to produce an oxidized product containing methanol and a spent air, separating the spent air from the oxidized product, contacting the spent air with an absorbent, an adsorbent, or a mixture thereof to remove at least a portion of any impurities in the spent air to produce a first purified air, and contacting the first purified air with a biological material to produce a treated air. |
