| Zusammenfassung: | In a disclosed embodiment, a chemical process has a pair of beds, with each of said beds having at least one connection to receive a source of gas, and for delivering gas downstream. Each of the beds includes chemical treatment elements. The system includes a connection to a source of a gas to be treated, and a connection for receiving treated gas to be delivered to a downstream use, a connection to a source of a cleaning gas, and a connection to deliver the cleaning gas downstream. A rotary valve includes a rotary actuator for rotating a valve to selectively switch each of the beds between the several connections. |
