Abstract: An expander may include a longitudinal axis, an inner casing split horizontally along the longitudinal axis, an outer casing split horizontally along the longitudinal axis and spaced radially outward from and encompassing the inner casing. Each axial end of the outer casing may form a respective gland seal housing, and the outer casing and inner casing may define an exhaust chamber therebetween. A plurality of expansion stages including a rotor shaft may be disposed within the inner casing and configured to expand the working fluid received from a working fluid source. A plurality of seals may be disposed within each of the gland seal housings and mounted circumferentially about the rotor shaft. The plurality of seals may include an annular seal, a plurality of dynamically self-adjustable seals disposed outboard of the annular seal, and at least one dry gas seal disposed outboard of the plurality of dynamically self-adjustable seals.

Abstract: System and method utilizing thermochemical energy storage for abatement of volatile organic compounds (VOCs) are provided. The system includes a thermochemical energy storage module cyclically operable in a discharging cycle and in a charging cycle. Abatement of VOCs may be performed in either cycle. Disclosed embodiments are expected to provide a zero-added carbon VOC abatement system that in certain situations can operate uninterruptedly 24/7 with the flexibility to facilitate consumption of energy during periods of inexpensive rates for electricity.
