  • Patent number: 4193776
    Abstract: The object of the invention is a method for the purification of the process condensate from synthesis gases or hydrogen plant.The process condensate is purified from contaminations dissolved in it by stripping it with process steam before it is used in the chemical process of the raw material conversion into hydrogen or synthesis gas at the pressure that is equal or higher than the pressure of this conversion process. The total steam containing volatile products of the process condensate degassing is recycled to the gas generation process and the process condensate is eventual transported to the water treatment station before using it as boiler feed water.

  • Patent number: 4181605
    Abstract: The water softening system hereof employs a treatment tank containing a mineral bed of ion-exchange resin granules, a brine tank, and a valve for periodically cycling water through the mineral bed for removing hardness and other undesirable factors therefrom, then passing a diluted brine solution through the bed in an opposite direction to its normal service flow to recondition and flush the bed. The control for the system includes electrically operated solenoid diaphragm valves, and a plunger valve responsive to water pressures, for controlling and regulating the flow of water and brine through the mineral bed. A venturi aspirator is incorporated in the plunger valve, whereby a saturated brine solution is drawn and with controlled dilution is caused to flow in a direction opposite to service flow through the mineral bed.

  • Patent number: 4162147
    Abstract: An apparatus for removing harmful substances from effluents has two chambers located symmetrically at opposite sides of an effluent channel. Each chamber contains two or more stacked trays which are each provided with a spiral flow path descending from a tray inlet to a tray outlet. All tray inlets are so located in the channel that substantially all effluent flowing in the channel is compelled to enter them and to travel by gravity through the respective tray. Air, an insert gas or a mixture of both is bubbled from below through the effluent flowing in the trays to expel and entrain the harmful substances. The treated effluent is then discharged back into the channel at locations downstream of its point of admission into the inlets.

  • Patent number: 4161395
    Abstract: A vacuum receiver comprising a closed top vertical cylindrical tank with a central vacuum takeoff at the top, a tangential downwardly inclined feed conduit in the sidewall, an inverted conical bottom section with anti-swirl baffles therein, and a barometric leg extending downwardly from the apex of the bottom to termination in submergence in a lower seal tank. A conduit is provided to recycle a portion of discharge liquor from the seal tank to the top of the barometric leg. The slope of the conical bottom does not exceed about 40.degree. from the vertical wall and inclination of the inlet conduit is about 15.degree. from horizontal. The barometric leg length and diameter as well as the liquor recycle rate are selected to optimize final liquor discharge rate at prevailing vacuum and foam conditions.

  • Patent number: 4157964
    Abstract: A filter system includes a tank with a removable cover at one end and a filter basket and liner therefor insertable into the tank to divide it into unfiltered liquid and filtered liquid zones. Inlet and outlet openings are disposed at the open and remaining end, respectively, of the tank with the inlet opening being in the side wall of the tank, near such open end, so as not to interfere with opening and closing of the cover. Inner and outer annuli are fixed to the tank side wall and face radially into the tank, with the inlet opening interposed axially therebetween. A spacer insertable into the tank comprises an annular inner disk pressable toward the inner annulus for gripping therebetween an inner resilient seal which in turn engages the adjacent edges of the filter basket and filter liner to prevent leakage therearound between the unfiltered and filtered liquid zones.

  • Patent number: 4155724
    Abstract: Drilling mud degasification apparatus comprises a degassing chamber located below the level of gas-laden mud in a tank. A propeller pump causes the mud in the tank to flow through a plurality of restricted orifices in the degassing chamber at a rate faster than that at which the mud would normally flow through such orifices to liberate the gas bubbles therefrom. A cyclone separator finally separates the so-liberated gas from the mud.
