Disclosed herein are components, systems, and methods for oxidizing a waste gas to produce a flue gas. Embodiments of a regenerative oxidizer include a heat exchanger supported within a heat transfer chamber without the use of a coldface. The regenerative oxidizer may include an inlet into the heat transfer chamber that is laterally aligned with at least a portion of the heat exchanger. The heat exchanger includes a heat exchange block having at least one lateral passageway extending therethrough, and at least one vertical passageway extending through a top face of the heat exchange block, but is devoid of any vertical passageways extending through a bottom face of the heat exchange block.

Abrégé

A seal assembly is provided that transitions from an expanded configuration to a retracted configuration. In the expanded configuration, the seal assembly forms a non-permeable seal between a rotatable rigid body and a non-rotatable rigid body, the non-permeable seal preventing the entry of oxygen into a reactor drum having a low oxygen environment and/or leakage of gases produced in the low oxygen environment of the reactor drum to the surrounding environment. In the retracted configuration, the rotatable rigid body is secured relative to the non-rotatable rigid body such that relative rotation is prevented. The first rigid body may be translatable relative to the second rigid body to reduce a length of the seal assembly and facilitate rapid removal and/or replacement of the seal assembly from between adjacent components of a torrefaction, gasification, or pyrolysis system.

Abrégé

A system is provided that enables a continuous process that involves the introduction of particles into a reactor drum having a low oxygen environment. Heavy hydrocarbons are boiled off of the particles during the heating of the particles. The boiled off heavy hydrocarbons mix with a heated gas stream that heats the particles within the reactor drum. The heated gas stream (with the boiled off heavy hydrocarbons) exit the drum and are recirculated back to a heat source for reheating the gas stream prior to reentering the reactor drum. Repeated exposure to the elevated temperatures within the reactor drum cracks the heavy hydrocarbons into lighter hydrocarbons. The lighter hydrocarbons may then be separated out of the heated gas stream and collected for sale or use.
