摘要:
A low-cost process for cleansing a liquid of volatile contaminants can be accomplished by cross flowing a liquid through a contactor vessel. As the liquid to be cleansed of contaminates cross flows through the horizontal contactor vessel, a radial flow pattern is induced in the liquid and the liquid is contacted with a cleansing gas introduced cross current to the flow of the liquid through the contactor vessel. As the liquid moves through the contactor vessel, contaminants enter the cleansing cross current gas percolating through the liquid. The cross current gas may then be collected and cleansed of the contaminates it collected. The cleaned cleansing gas may then be recycled back into the contactor vessel. The liquid to be cleansed may by any liquid or liquefied hydrocarbon, such as liquefied petroleum gas, gasoline, diesel, refinery component streams, distillates, gas oils, crude oils and/or emulsions. The volatile contaminates that may be cleansed from liquid include any undesirable element within the cross flowing liquid that can be absorbed and/or dissolved in the cleansing cross current gas percolated through the liquid. The cross flowing liquid may be cleansed to varying degrees, depending on specific down streams requirements.
