The permeate is passed to the PX recovery unit for recovery of PX, which the retentate is bypassed around the PX recovery unit circulated through the xylene processing loop.

Abstract: Vehicle power control, particularly during idling conditions, is described. A vehicle power control system includes a first circuit, a power converter in electrical communication with the first circuit, and a system controller. The system controller controls the power converter to convert a first supplied voltage to a first demanded voltage in response to an energy demand at the first circuit and in response to a determination that the first supplied voltage is within a first voltage range. The system controller controls the power converter to supply the first demanded voltage to the first circuit. Additionally, the system controller can control the power converter to convert the first supplied voltage to the first demanded voltage at a ratio of 4:1 to eliminate high-voltage battery support.

Abstract: A full duplex, low latency, near field data link controls a resonant induction, wireless power transfer system used for recharging electric vehicles and other electrically powered devices. A coherent transponder configuration enables low complexity synchronous detection and positive rejection of signals originating from nearby and adjacent vehicles. A reference crystal oscillator in the ground side apparatus provides frequency synchronization for both the forward and the return data links. Transmission is by means of near field magnetic induction between pairs of loop antennas which, together with the effective waveguide below cutoff structure comprised by the vehicle underbody and the ground surface, largely restrict signal propagation to the area in the immediate vicinity of the system antennas.

Abstract: A method for adjusting reactance includes an adjustable reactance generator including a comparator receiving an input sinusoidal waveform and outputting a square wave that retains the frequency and phase of the applied sinusoidal waveform. The reactance adjustment is generated using a power switching circuit that receives the square wave from the comparator as a control signal and outputs a square wave that retains the frequency and phase of the applied sinusoidal voltage waveform, an adjustable power supply that adjusts the amplitude of the square wave output by the power switching circuit, and an amplitude detector that controls the output level of the adjustable power supply. The power switching circuit output, when converted to a sinusoid, provides the effect of an adjustable reactance.
