Abstract: Pulsed absorption contactor systems and methods are provided. The systems include a vessel having inlet and outlet ends and a pulse generator system, a gas inlet configured to direct an input gas stream into the vessel, a gas outlet configured to receive an output gas stream and direct the output gas stream out of the vessel, a liquid inlet configured to direct an input liquid stream into the vessel, and a liquid outlet configured to receive an output liquid stream and direct the output liquid stream out of the vessel. The pulse generator system is configured to induce a fluctuation in the input gas stream, the input liquid stream, and/or a combination of the input gas stream and the input liquid stream.

Abstract: A system for determining the level of solids accumulated in a sand separator has a vibratory level sensor and a solid separator control system. The vibratory level sensor includes a vibratory rod and an exciter connected to the vibratory rod. In some embodiments, a vibration sensor is connected to the vibratory rod to monitor changes in the vibration of the rod. In other embodiments, changes in vibration are measured by looking at the rotational speed and power inputs at the exciter.
