摘要： A process for converting the naphtha fractions distilled from crude oil into greater volumes than heretofore of a gasoline product having higher octane number and a distillate stream of improved cetane number and smoke point by sending the lower boiling naphtha fraction directly to the gasoline pool and subjecting the higher boiling naphtha fraction to a mild reforming treatment, extracting the reformate to separate two streams, aromatics which are directed to the pool and paraffins which are sent to a splitter to separate the paraffin stream into fractions greater than C.sub.8 and a C.sub.8 or less fraction. The C.sub.8 or less fraction is cracked, thermally or catalytically and alkylated and/or polymerized before being directed to the gasoline pool. The fraction from the splitter containing hydrocarbons greater than C.sub.8 can be used in the distillate pool.

摘要： There is disclosed a system for measuring and controlling the concentration of hydrogen in hydrogen recycle processes used in oil refineries and petrochemical plants. The system is intended to permit reduction in hydrogen use in hydrogen-consuming hydrogen recycle processes. The system is dependent on the recognition that a decrease in cooling medium temperature results in an increase in vent gas flow, which can be decreased to the minimum permissible without endangering catalyst activity and stability and product yield if hydrogen concentration is monitored, and that partial pressure is the key parameter.

摘要： A process for simultaneously generating power and recovering potable water from a source of salinous water -- e.g. sea water. Salinous water, from a locus which is proximate to the surface thereof and at a relatively high temperature -- e.g. about 85.degree. F. -- is increased in temperature via indirect contact with a vaporous phase, derived from the surface water at an elevated temperature and a subatmospheric pressure. The preheated salinous water is exposed to radiant solar energy, in a solar radiation heat sink, to further increase the temperature thereof. Thus-heated salinous water is introduced into a first flash separation zone, maintained at subatmospheric pressure, to provide a first substantially non-salinous vaporous phase and a first salinous liquid phase. The first vaporous phase is passed into and through a turbine, from the resulting motion of which power is generated. The first liquid phase is introduced into a second flash separation zone, maintained at a lower absolute pressure than said first flash zone, to provide a second salinous liquid phase and a second substantially non-salinous vaporous phase. The latter is utilized to preheat the salinous surface water prior to the introduction thereof into the solar radiation heat sink. The second liquid phase is introduced into a third flash separation zone, maintained at a lower absolute pressure than said second flash zone, to provide a third salinous liquid phase and a third substantially non-salinous vaporous phase. Vapors exiting from the turbine and the third vaporous phase are cooled and/or condensed via indirect contact with a second portion of the salinous water, obtained from a locus substantially lower than the surface, and at a comparatively lower temperature -- e.g. about 70.degree. F. -- to recover liquid potable water.The third salinous liquid phase is returned to the original source of the salinous water, as is the second salinous water portion following its use to condense and/or cool the turbine exit vapors and the third vaporous phase. When returned to the salinous water source, the third salinous liquid phase is preferably at a temperature not more than 15.degree. F. greater than the temperature of the second salinous water portion obtained at the selected depth below the surface.

摘要： A process for simultaneously generating power and recovering potable water from a source of salinous water -- e.g. sea water. Salinous water, from a locus which is proximate to the surface thereof and at a relatively high temperature -- e.g. about 85.degree. F. -- is exposed to radiant solar energy to increase significantly the temperature thereof -- e.g. to a level of at least about 135.degree. F. The heated water is introduced into a plurality of flash separation zones, each succeeding one of which is maintained at a lower subatmospheric pressure than the preceding zone, to provide substantially non-salinous vaporous phases. The salinous liquid phase is introduced in series through the plurality of flash zones. The vapor phases are passed through separate, individual turbines, or are introduced into different stages of a multi-stage turbine, from the resulting motion of which power is generated. Vapors exiting from the turbines are condensed via indirect heat-exchange with a second salinous water portion, obtained from a second depth substantially below the surface, and at a comparatively lower temperature -- e.g. about 70.degree. F. -- to recover liquid potable water. The salinous liquid phase emanating from the last flash zone is used to vaporize, via indirect heat-exchange, a hydrocarbon; this is passed through a separate turbine, and additional power is generated. The exiting hydrocarbon vapors are condensed, via indirect heat-exchange with the second salinous water portion, and re-vaporized. The last salinous liquid portion, following heat-exchange with the hydrocarbon, and at a temperature of at least about 90.degree. F., is introduced into a separate vacuum flash separation zone, maintained at an absolute pressure less than that of the last flash zone in said plurality, and additional potable liquid water is recovered from the resulting non-salinous vaporous phase.The second salinous water portion, following condensation of the exiting turbine vapors, and the last obtained salinous liquid phase, from the separate flash separation zone, are returned to the original source of salinous water. The salinous liquid phase, returned to the sea water source, is at a temperature not more than 15.degree. F. greater than the temperature of said second salinous water portion.

摘要： There is disclosed a system for measuring and controlling the concentration of hydrogen in hydrogen-consuming hydrogen recycle processes used in oil refineries and petrochemical plants. The system is intended to reduce utilities and hydrogen usage by means of adjusting vent gas flow and the quantity of hydrogen and hydrocarbon vapor circulating to obtain the operating parameters which yield minimum cost. Specifically there can be a savings of compressor power, fuel required for heating, and hydrogen. The system is dependent on the recognition that a decrease in cooling medium temperature results in an increase in hydrogen flow, which can be decreased to the minimum permissible without endangering catalyst activity and stability and product yield if hydrogen concentration is monitored, that partial pressure is the key parameter, and that it is advantageous to optimize.

摘要： A process is disclosed for driving a turbine, which preferably is connected to an electrical generator, using energy supplied by the reboiler system of a fractionation column. The portion of the bottoms liquid of the column which is to be recycled through the reboiler is pressurized by a pump, and the high pressure liquid is heated and vaporized or brought to a supercritical state in the reboiler. The resultant high temperature stream is then depressurized through the turbine down to the desired pressure and temperature of the vapor stream used to reboil the column. The process is an extremely efficient method of generating electrical energy in a petroleum refinery or petrochemical installation.

摘要： A method is disclosed for recovering useful energy from the overhead stream of a fractionation column. A high efficiency for the overall process is achieved by first removing heat from the overhead stream by vaporizing an expansion turbine working fluid stream and by then removing an additional amount of heat in a working fluid preheater. The amount of working fluid flowing through the preheater is more than is vaporized by exchange against the overhead stream. The remaining liquid-phase portion of the working fluid is separately passed into a second vaporizer having a different heat source.

摘要： A control system and a method for regulating the division of a single feed stream between two or more pieces of processing equipment operated in parallel. The feed stream enters a three-way valve and is then equally divided into two smaller streams which flow through separate pieces of process equipment and then through separate check valves. The pressure of each of the smaller streams is monitored to detect leakage in either piece of the equipment. The flow normally passing through the leaking piece of equipment is diverted to the intact piece of equipment when the leakage causes a predetermined pressure difference.
