Thermally efficient nonpolluting system for production of substitute natural gas
Abstract
Abstract SULFUR-FREE, METHANE-RICH SUBSTITUTE NATURAL GAS IN PRODUCED FROM A HIGH SULFUR CRUDE OIL BY A NONPOLLUTING PROCESS CAPABLE OF ACHIEVING AN UNEXPECTEDLY HIGH TERMAL EFFCICENCY. THE PRROCESS COMPISES SEPARATING WHOLE CRUDE OIL INTO A PLURALITY OF FRACTIONS COMPRISING A BOTTOMS FRACTION AND A LIGHTER OIL FRACTION, DESULFURIZING AND HYDROCRACKING THE OIL FRACTION INTO A SUBSTANTIALLY SULFUR-FREE NAPHTHA IN THE PRESENCE OF HYDROGEN, WHICH IS PROVIDED BY CONVERTING A RESIDUE PORTION OBTAINED FROM THE BOTTOMS FRACTION. THE RESULTING SULFUR-FREE NAPHTHA IS COVERED INTO SUBSTITUTE NATURAL GAS IN THE PRESENCE OF STREAM. NOT ONLY IS A THERMAL EFFICIENCY OF APPROXIMATELY 100 PERCENT OBTAINED, NOTWITHSTANDING THE USE OF A PORTION OF THE CRUDE OIL FOR REFINERY FUEL, BUT NAPHTHA IS PRODUCED AT A VOLUMETRIC EFFICIENCY OF ABOUT 100 PERCENT BASED UPON THE CRUDE OIL FEEDSTOCK. THE SYSTEM IS AUTOGENIC WITH RESPECT TO HYDROGEN REQUIREMENTS FOR DESULFURIZATION, NITROGEN REMOVAL, AND HYDROCRACKING. D R A W I N G
