High pressure gas dehydration with liquid desiccant
Abstract
Abstract PROCESS AND APPARATUS FOR DEHYDRATING WET, HIGH-PRESSURE, ESSENTIALLY HYDROCARBON GAS WITH LIQUID DESICCANT IN A CONVENTIONAL DESICCANT-CONTACTING AND DESICCANT-REGENERATING CYCLE, IN WHICH A DROP IN GAS PRESSURE OCCURS IN A SEPARATOR HAVING A VERTICAL AXIS CYLINDRICAL PORTION INTO WHICH THE WET GAS IS INJECTED TANGENTIALLY AND HORIZONTALLY WITH A LOWER NONCYLINDRICAL PORTION TO DAMPEN SWIRLING OF THE SEPARATED LIQUID. THERE MAY BE CONTROLS ON THE GAS AND LIQUID OUTLETS OF THE SEPARATOR AND HEAT EXCHANGE BETWEEN THE STEAM FROM THE DESSICCANT REGENERATOR AND THE MAKE-UP DESSICCANT. HYDROCARBON GAS FLASHING FROM THE LIQUID IN A SEPARATOR MAY BE USED AS FUEL FOR HEATING AND REGENERATING THE LIQUID DESSICCANT. HYDROCARBON LIQUIDS SEPARATED IN THE PROCESS CAN BE ADDED TO THE DRIED GAS AFTER DEHYDRATION OF THE GAS.
