1. A system for controlling emissions from a wood drying process, comprising:
an exhaust stream from a wood drying process, the exhaust stream comprising one or more of particulate wood matters, terpenes, formaldehyde, methanol, acetic acid, acetone, or fatty acids; and
an adsorber, coupled to the exhaust stream, the adsorber configured to contain a sorbent for capturing the one or more of particulate wood matters terpenes, formaldehyde, methanol, acetic acid, acetone, or fatty acids from the exhaust stream to generate a purified air stream containing less than 10 wt % of the one or more of particulate wood matters terpenes, formaldehyde, methanol, acetic acid, acetone, or fatty acids in the exhaust stream;
a desorber coupled to the adsorber and configured to desorb the one or more particulate wood matters, terpenes, formaldehyde, methanol, acetic acid, acetone, or fatty acids captured by the sorbent; and
a side stream reactivator configured to reactivate a portion of spent sorbent within the system, the side stream reactivator coupled to the desorber, the adsorber or both the adsorber and the desorber.
