Abstract: A system and method for removing water from a liquid desiccant such as a glycol used to dry cooled air in order to restore the desiccant to a purity up to around 97% in a closed continuous flow process. Liquid desiccant can be sprayed into cooled air in a conditioner where it gains moisture. The wet or gained desiccant can be optionally preheated in an economizing heat exchanger and then routed into a concentrator. Desiccant pure to around 97% can be removed from the concentrator, passed through an economizing heat exchanger to provide the preheating and returned to the conditioner holding area. The concentrator can be heated by steam or other means such as natural gas to boil the wet desiccant causing mixed vapor to enter a vertical distillation column where most of the glycol condenses out on the column packing or plates and returns to the concentrator.

Abstract: Modern warships are designed to withstand the effects of a near miss underwater explosive event. To demonstrate that ship structure and equipment are designed and built to the requisite standard it is common for the entire warship to be shock tested by detonating controlled explosive charges in close proximity to the vessel. By using a partially phased and partially synchronous array of seismic airguns of the type used in oil exploration it is possible to simulate the explosive shock wave and provide a safe, repeatable and more environmentally benign test. The method can be used to provide shock excitation directly onto the keel of a vessel due to the relatively low energy of the airgun discharge bubbles in addition to the more conventional off-beam scenarios. This novel method of shock testing can be applied to ships, submarines, underwater equipment and test models or specimens.
