Abstract: Low profile diverters for, and the use of such diverters in, fracing operations to stimulate production of oil and gas are capable of seating against and temporarily sealing perforations, even when frac fluid is being pumped at high rates and pressures, or in horizontal or highly deviated well bores, where conventional ball sealers cannot be reliably used because of high flow rates and pressures.

Abstract: An automatically controlled water spray-based air purification system having a humidification portion and a dehumidifying portion is operatively installed in an air handling unit used to recirculate air within a conditioned space. A blower within the air handling unit housing operates to draw return air into the housing, flow the air across the entire air purification system, and then discharge the purified and humidified air back into the conditioned space. Upon sensing an excess humidification of the air, a humidistat operates a supply air/return air damper system to cause a portion of the air interiorly traversing the housing to bypass the humidification portion of the purification system to thereby reduce the moisture content of the air discharged from the unit. A water spray portion of the purification system is served by a pump forcing water from a sump structure through a filter, with the spray water draining back into the sump after cleansing air traversing the purification system.

A water spray portion of the purification system is served by a pump forcing water from a sump structure through a filter, with the spray water draining back into the sump after cleansing air traversing the purification system. Upon a sensed demand therefor, an additive injector adds suitable chemical treatment material to the sump water, and a water pollutant monitor structure operates to backwash the filter upon sensing an undesirable pump back pressure increase or a buildup of particulate and gaseous pollutants in the sump water.

Abstract: An automatically controlled water spray air purification system is incorporated in a heating, ventilating and air conditioning unit serving a conditioned interior building space. The purification system is operative to receive a portion of the return air that would normally be flowed through the unit, mix the received return air with a quantity of outside ventilation air, purify the return air/outside air mixture using water sprayed from a sump portion of the purification system, and flow the purified air into the unit for mixture therein with the balance of the return air being flowed therethrough to the conditioned space. Damper structures on the unit and its associated air purification system permit selective variance of the percentage of the unit discharge air that has traversed the purification system.
