Underwater gas detection system
Abstract
Abstract IN A HYDROCARBON DETECTION SYSTEM FOR USE IN AN EXPLORATION SURVEY OVER WATER COVERED AREAS, SAMPLES OF WATER ARE TAKEN, IN WHICH HYDROCARBON GASES MAY APPEAR IN A DISSOLVED STATE. REMOVAL OF DISSOLVED GAS FROM THE SAMPLE IS ACCOMPLISHED BY ADMITTING THE SAMPLE TO A CHAMBER, PASSING IT THROUGH A FOG NOZZLE, AND APPLYING A VACUUM TO REMOVE THE GAS FROM THE SAMPLE, THUS CREATING FOG, LIQUID, AND GAS ZONES IN THE CHAMBER. GAS IS REMOVED FROM THE TOP AND LIQUID IS DISCHARGED FROM THE BOTTOM OF THE CHAMBER BY PUMPS. VALVES ARE LOCATED IN THE LIQUID ENTRANCE LINE AND THE DE-GASSIFIED LIQUID EXIT LINE, AND ARE CONTROLLED BY LIQUID LEVEL RESPONSIVE DEVICES. THE REMOVED GAS IS SUBJECTED TO ANALYSIS. D R A W I N G
