Abstract: CONTROL TECHNIQUE FOR CONVERSION OF  OXYGENATES TO LIQUID HYDROCARBONS                            ABSTRACT     A process control technique for upgrading C3-C4 hydrocarbon feed containing olefins to produce heavier liquid hydrocarbons comprising converting a major portion of C3-C4 olefins in an oligomerization zone by contacting a shape selective medium pore zeolite catalyst at elevated temperature and pressure to make distillate and olefinic gasoline.  The oligomerization stage effluent is fractionated to provide distillate and gasoline product and a C3-C4 intermediate stream containing isobutane and unconverted propene and butylene.  The C3-C4 intermediate stream is combined under control with a portion of C3-C4 feed and further converting the combined streams in an alkylation zone to make heavier paraffinic hydrocarbons.  The olefin feed may be produced by catalytically converting methanol or similar oxygenated hydrocarbons in a known process.  Controlled material balance is achieved by accumulating liquid olefin feed to the oligomerization and alkylation units using a surge drum with liquid level control. By-product isobutane is recovered and recycled under liquid level control operatively connected to determine feed of liquid olefin to the conversion units.

Title: Compensated individual segment flow regulator
Inventor: JANECKE JAMES P
IPC: F15B13/042
Filed: 1988-10-03
Granted: 1992-06-02
Abstract: ABSTRACT OF THE DISCLOSURE     An individual segment flow regulator is shown having a two landed spool and two landed bore, all with the same nominal diameter, a plug, a spring and a sensing passage from the main spool of the valve.  Supply oil entering between the two lands of the bore is separated from a sensing pressure by one spool land which is slidable within the bore.  The other spool land meters the supply fluid.  The metering land of the regulator spool opens away from the valve bore land to allow supply fluid through and can shut off the supply.  A spring chamber above the spool senses the load pressure which opens the metering spool, thereby increasing the flow and therefore the pressure drop across the main spool area opening. Feedback pressure developed at the bottom of the metering land of the spool is used to close down the regulator spool as the flow, and therefore the pressure drop, across the main spool increases beyond the pre-load force of the bias spring.  The feedback land at the bottom of the spool is also the metering land that controls supply pressure to the regulated pressure.
