Abstract: Contaminated glycol in a natural gas dehydration plant is refined by vacuum distillation. The equipment to perform the refining by vacuum distillation is mounted upon a trailer. The equipment on the trailer is connected by an inlet line to the dehydration plant to receive the contaminated glycol from the plant. The refined glycol is continuously pumped back to the dehydration plant by a conduit. Detergents may be added to the glycol unit so that the circulating glycol cleans the equipment of the dehydration plant as the hazardous materials is separated from the glycol. The dehydration plant remains in operation during the time that the glycol is refined and the dehydration plant equipment cleaned. When the process is complete at one dehydration plant the trailer is towed to another dehydration plant for refining the glycol and cleaning the dehydration plant.

Abstract: Disclosed is a water distiller of the type having a raw water container, a heater for boiling water in the container and a thermostat for disabling the heater. In the improvement, the container includes a water cavity having a upper perimeter around a panel and the heater is mounted in heat-transfer relationship to the panel. The container includes a thermostat in heat-transfer relationship to the panel and connected to the heater. When water diminishes to a level at which the panel is no longer submerged, the panel temperature rises and trips the thermostat.A heater retention member secures the heater to the panel and a reflective heat shield has a first portion spaced from the retention member. The heater is between the panel and the first portion. The thermostat projects through an aperture in the retention member and an opening in the heat shield so that such thermostat is in intimate, heat-transfer relationship to the panel.

Abstract: Contaminated glycol is refined by vacuum distillation. Specifically the evaporator is heated to a temperature below the degradation temperature of the glycol. The vacuum is used to bring the flashpoint down sufficiently so that glycol evaporates or flashes at that temperature. The glycol is condensed and filtered through activated granular carbon. The principal use of refining the glycol is to refine the triethylene glycol used in natural gas dehydration plants. For such purposes the equipment is mounted upon a trailer to be taken to the plant for cleaning glycol. In such instance, in addition to refining the glycol, a cleaning agent (which contains a degreaser) is added to the refined glycol. The glycol is refined while the natural gas dehydration plant is in normal operation and therefore it is not necessary to stop the natural gas dehydration plant for refining the glycol used therein.

The distilland water is heated with an electric heating element and the distillate is discharged through a carbon filter into a discrete glass pitcher adjacent to the boiler. The arrangement permits easy removal of the boiler from the housing for filling with distilland or cleaning, as well as the convenient replacement of the boiler in the housing afterwards.

The fluid products escape outwardly from the porous cylinder and are transferred to a heat exchanger chamber where they are cooled. A fractional distillation system stratifies the fluid products according to weight for purposes of recovery.

Abstract: A system for removing volatile constituents (e.g., hydrocarbons) from a liquid (e.g., water) containing the same by which there is a continuous countercurrent contact between the liquid and a forced air flow. Water collected in a reservoir is continuously pumped to the top of a stripping tower where it is dispersed downwardly over packing material. A blower forces air upwardly in the tower so as to remove the volatile constituents that exit the tower with the exit air. Since the water flow is continuous, multiple passes occur through the tower to enhance separation efficiency. Water from the base of the tower returns to the reservoir via overflow from a standpipe. A lower liquid level sensor in the reservoir initiates operation of the water pump to the tower, and an upper liquid level sensor initiates operations of another pump for pressure discharge from the base of the tower to an exterior site.

The volatilized contaminants are purged with small amounts of air or other non-condensible gas and with superheated steam. The organic constituents can be captured in a vapor phase or they can be condensed and captured in the condensed liquid.
