Title: Electrolytic apparatus for generating specific concentrations of h2 gas in a flowing gas stream
Inventor: LAYZELL DAVID B
IPC: C25B1/04
Filed: 1994-03-01
Abstract: ABSTRACT OF DISCLOSURE An apparatus for electrolytically generating small volumes of a selected gas such as hydrogen for introduction into a flowing gas stream is described. The gas stream flows through an electrolytic cell wherein the selected gas is generated at an electrode and a portion of the gas stream is diverted through a needle valve and a non-conducting capillary with a small orifice to deliver gas to the electrodes so as to dislodge the selected gas bubbles forming thereon and carry them into the flowing gas stream. To maintain the level of electrolyte in the cell, the cell is connected by a narrow tube to a reservoir of electrolyte. The reservoir has a volume and surface area many times greater than that of the cell and the gas volume above the reservoir is maintained at the pressure and composition of the gas stream entering the electrolytic cell.

Abstract: A method and apparatus for removing fines, such as sand, from a crude oil tank is disclosed.  The method generally includes the steps of directing a fluid into the bottom of the tank to stir up the sand settled therein to create a sand and fluid  slurry.    The  method  further  comprises  the  step  of suctioning the slurry from the tank.  To accomplish the steps, a pressure line is coupled to a pump which jettisons fluid through holes in the pressure line located near the bottom of the oil tank to stir the fines, thereby creating a slurry.  A drain line is also located near the bottom of the tank, and is coupled to another pump for simultaneously suctioning the slurry through the drain line outside of the tank.  In another aspect of the invention, a gravel or dump truck, or the like, is retrofitted with the pressure line and drain line pumps and tubing adapted to couple the drain line to the bed of the truck so that the slurry is extracted from the tank through the drain line into the bed of the truck.
