Abstract: IMPROVED PROCESS FOR CONVERTING METHANOL TO ALKYL ETHERS                        ABSTRACT     A multistage process for producing isoalkyl ethers from lower aliphatic oxygenate feedstock, such as methanol.  Feedstock is catalytically converted in a primary catalyst stage at elevated temperature in contact with zeolite catalyst to predominantly C2-C7 lower olefins comprising isobutylene and isoamylene, by-product water and a minor amount of C8+ hydrocarbons, followed by fractionation of the C2-C7 olefins to recover a C2-C3-rich recycle stream for further catalytic conversion in the primary stage.  C4-C7 olefins are passed to a second catalytic etherification stage for reaction of isoalkenes with methanol to produce methyl tertiary-butyl ether, methyl isoamylether and higher isoalkyl ethers.  The second stage effluent may be fractionated to recover an ether product, C5+ hydrocarbon liquid product, and unreacted butenes.  Advantageously, the unreacted butenes are further reacted with isoparaffin in a third catalytic stage under acid catalysis alkylation conditions, and fractionated to recover C6+ alkylate liquid, liquid hydrocarbon product.  The ethers may be blended with at least one C6+ hydrocarbon to produce high octane gasoline.

Abstract: TRACTOR MOUNTED SWATHER            ABSTRACT      A swather including at least a front swather head and one side swather head having mountings for mounting the front head on a tractor for support by the front of the tractor and for mounting the side head in a manner to permit the rear of the tractor to support at least the inner end of the side swather head.  The mountings are such that they permit the heads to be adjusted to a number of different travel modes. In one mode of travel, the side head can be moved to a position trailing the tractor and the front head is carried in a raised position at the front of the tractor.  The movement of the side head can be accomplished from within a cab of the tractor.  Another mode of transport is possible by providing a mechanism for demounting and carrying the front head.  For this mode the side head is moved to the trailing position as just described, and the front head is pulled lengthwise behind the side head.  In yet another mode of transport, the side head is also readily demountable from the tractor and carried on a separate device to the both heads can be pulled one behind the other by a road vehicle, such as a truck.

The steps involve the conversion of sulphur dioxide to sulphur trioxide in a catalytic converter (40, 360, 570), the reaction of sulphur trioxide with lime and/or lime-stone in a fluidized reactor (60, 410, 580), and removal of heat from the chemical reactions for utilization in the production of superheated steam. The superheated steam that is produced can be used for the generation of electricity, for operating mechanical devices, space heating, lime production, construction materials curing, and heat exchange processes.

Abstract: Abstract A support apparatus for tubes in a V-bend portion of a tube bundle. The support apparatus includes a U-tube ring positioned around the tubes in the V-bend portion and having first and second tube separation elements extending therefrom through first and second lanes between the tubes, respectively. The first tube separation elements are preferably characterized by flat plates or strips defining a plurality of holes therethrough, and the second tube separation elements are preferably characterized by rods or bars extending through aligned sets of holes in the plates or strips. A support bar extends between opposite end portions of the ring, and the plates have notches therein for engaging corresponding notches in the support bar and ring. The ring and support bar are slidably attachable to a mounting bracket on a tube support used to support a first and second pass of longitudinal tubes in the tube bundle. A method is disclosed for fabricating the U-bend tube support.
