DEVICE TO CLEAN SILOXANES FROM BIOGAS, AND A METHOD OF REGENERATING THE SAME INCLUDING ELECTRIC SWING ADSORPTION

摘要

A siloxane-adsorbent media regeneration device, system and method comprising a rectangular cylinder with first and second dielectric elements forming opposing first and second sides, and first and second electrodes forming opposing third and fourth sides thereof, and end caps disposed at opposing ends thereof. A capacitive device is coupled with the dielectric elements and configured to detect a capacitance of an adsorbent media, and a switchable heat source coupled with each of the first and second dielectric elements. A pressure vessel is configured to receive the rectangular cylinder therein, and includes apertures to permit inflow and outflow of a gas. A vibration-generating device may be coupled with one of the electrodes, as well as with a control system. Regeneration generally includes passing an electrical current through an adsorbent medium, detecting a capacitance indicating that regeneration is warranted, and heating the adsorbent medium while conveying an inert gas therethrough.
