Abstract: A method and an apparatus for reclaiming deicer from produced water of an oil or gas well includes a fractionation tower having a top condenser section, a bottom heat exchanger section and an intermediate packing section. A deicer outlet is positioned in the condenser section, for removal of condensed deicer. An inlet is provided to receive produced water contaminated by deicer. The inlet is coupled to the condenser section such that produced water must pass through the condenser to enter the inlet. A water outlet is provided in the heat exchanger section. Operation of the water outlet is controlled to maintain a predetermined level of accumulated water in the heat exchanger section. The heat exchanger is adapted to be coupled with a source of hot fluids produced by an external heat source. The circulation of hot fluids through the heat exchanger heats accumulated water in the heat exchanger section.

Abstract: A three-dimensional photographic technique comprises scanning the outside surface of the three-dimensional surface such as a human subject using a color digitizer which generates spatial and color data relating to the outside surface. The spatial data is used to generate a mold having a concave surface corresponding to the outside surface of the subject. A thin hollow shell of transparent plastics material is molded in the mold to define an outer surface of the shell which corresponds to the outer surface of the subject. The photographic material is applied on the inside surface of the hollow shell and is exposed using an image manipulation system and fiber optic transportation system which extracts the light from a screen and transmit it to a position adjacent the outside surface of the hollow shell to provide the required colored image on the photographic material for display through the transparent material of the hollow shell.
