Simplified gas or liquid treating and/or dehydration process
Abstract
Abstract THE REMOVAL OF IMPURITIES SUCH AS HYDROGEN SULFIDE, CARBON DIOXIDE, AND WATER FROM A GAS OR LIQUID SUCH AS NATURAL GAS OR A HYDROCARBON, IS ACCOMPLISHED BY TREATING THE GAS OR LIQUID AND AN ABSORBENT LIQUID OR REAGENT IN A TREATER OR AN ABSORBER, OBTAINING A PURIFIED GAS OR LIQUID AND AN ENRICHED ABSORBENT LIQUID OR REAGENT. THE ABSORBENT LIQUID IS PASSED WITHOUT PRIOR ESSENTIAL HEATING DIRECTLY TO THE TOP OF A STRIPPER OR REGENERATOR WHEREIN IMPURITIES ARE RELEASED WITH THE AID OF HEAT. HEAT IS SUPPLIED, FOR EXAMPLE, BY REBOILING THE ABSORBENT LIQUID IN THE STRIPPER OR THE REGENERATOR. THE ENRICHED LIQUID ACTS IN THE STRIPPER OR REGENERATOR TO CONDENSE VAPORIZED ABSORBENT OR REAGENT LIQUID WHICH NORMALLY WOULD PASS THEREFROM THEN TO BE CONDENSED AND LATER RETURNED. HOT, LEAN ABSORBENT LIQUID OR REAGENT RECOVERED FROM THE STRIPPER OR REGENERATOR IS COOLED BY EXTERNAL COOLING MEDIA AND RETURNED TO THE TREATMENT. THIS COOLING IS THE SOLE ESSENTIAL COOLING OF THE LIQUID ABSORBENT OR REAGENT IN THE OVERALL OPERATION. IN MAY CASES THIS COOLING IS THE SOLE ESSENTIAL COOLING IN THE OVERALL OPERATION.
