Abstract: The present invention provides a manually powered drive assembly for a vehicle. A foot crank winds a helical torsion spring through a system of shafts and sprockets in a first direction. By releasing a brake applied to a wheel, or wheels, of the vehicle, the wound spring transfers a rotational movement from a spring shaft to a freewheel sprocket coaxially aligned with the axle supporting a wheel, so that the rotational movement upon the wheel assists a user in manually moving the vehicle. The drive assembly may be advantageously used with a wheelbarrow to assist in building up momentum for moving heavy loads.

Abstract: Isobutane and propane are separately charged to different catalytic dehydrogenation zones. The reaction products, including principally propylene and isobutylene, are combined, followed by separation of steam condensate, carbon dioxide and fuel gas from the mixture of effluents from the two separate dehydrogenation reaction zones. Propane and propylene are then separated from the isobutylene. The propylene product is recovered, and isobutylene is charged to an etherification reactor and there reacted with methanol to yield methyltertiarybutyl ether (MTBE). The etherification reactor effluent is fractionated to separate MTBE from n-butane and from isobutane. The latter is separated from n-butane and recycled to the isobutane dehydrogenation zone. Unreacted propane is also recovered and recycled.

Abstract: A super-pressured, sub-cooled feed gas, predominating in methane and containing significant amounts of ethane and higher hydrocarbons and nitrogen, is separated by passing the feed gas through at least one separation step to separate a vapor phase and a liquid phase, fractionating the liquid phase to recover ethane and higher hydrocarbons as a liquid and a pipeline gas as a vapor phase product, the vapor phase from the separation step is then sequentially fractionated in second, third and fourth fractionation steps to produce liquid phase from the second fractionation step, which is recycled to the first fractionation step as a reflux, a liquid phase from the third fractionation step which is recovered as a product pipeline gas, a liquid phase from the fourth fractionation step which is recovered as an in-plant fuel and a vapor phase from the fourth fractionation step which is vented to the atmosphere as substantially pure nitrogen.

Abstract: Overloading of a plurality of turbine drivers driving compressors in a plurality of compression cycles, such as the compression of refrigerants and the compression of normally gaseous feed in a method for cryogenically cooling such normally gaseous feed, due to changes in compressor limiting operating conditions, is prevented by measuring the suction pressures to the low pressure stages of the compressors, deriving a desired feed flow rate in response to each of such measured suction pressures, selecting the lowest desired feed flow rate (which will be derived in response to the highest measured suction pressure if all set points are equal), and adjusting the feed gas flow rate in response to the lowest flow rate. In a preferred embodiment, a manual set point representing a maximum feed gas flow rate is also applied and the selected feed rate is dictated by the highest suction pressure or the maximum feed rate, whichever is lower, and is utilized to adjust the feed rate.

Abstract: In the separation of low boiling gases such as ethane or propane and heavier from a gas stream such as natural gas, a first portion of the feed is heat exchanged with an overhead from a downstream stripper column, such as a demethanizer, a second portion is heat exchanged with a stream from a lower portion of said stripper column, and these two portions passed as separate streams to a separator-contactor. The first stream is added at a point above the second. This results in an increase in the recovery of liquid products.

Abstract: In the separation of low boiling gases such as ethane and heavier from natural gas utilizing two expanders in series, liquid condensed before expansion is not passed to the fractionator but is flashed and the resulting vapor combined with the expanded vapor from the first expander. This results in both increased work output from the second expander and simplified design of the downstream fractionator column since it reduces the amount of lighter materials introduced into the lower section thereof.
