Methods and systems for obtaining exhaust streams from wood drying processes and controlling emissions in exhaust streams from wood drying processes are provided. Methods and systems can include pre-treatment steps, such as removing particulate matter and/or heating a process exhaust stream from a wood dryer, in order to obtain an exhaust stream that is suitable for downstream recovery of terpenes from said exhaust stream. Exhaust streams can be contacted with a sorbent to remove volatile organic compounds, and other emissions, generating a purified air stream that is able to be released into the environment without further purification or oxidation.

Methods and systems for controlling emissions from wood drying processes

Methods and systems for recovering terpenes and controlling the composition of terpenes collected from wood drying processes are provided. In particular, a sorbent having adsorbed materials, including terpenes, from a wood drying process can be desorbed in a desorber, resulting in a gaseous stream containing terpenes, which can be condensed and collected from the gaseous stream. The conditions of desorption can be controlled to ensure a desirable amount of alpha-pinene and beta-pinene relative to other terpenes, such as dipentene and camphene, in the collected terpenes.
