Abstract: A water deflection system is provided for use with a wall mounting assembly, wherein the water deflecting system and the wall mounting assembly are suitable for mounting to a wall of a structure, such as a building. The mounting plate and the cover plate of the wall mounting assembly are spaced apart from one another and/or provide sufficient clearance to allow for a downward flow of water therebetween. The water deflection system interrupts, channels, and/or directs this downward flow of water and safely diverts the water away from the region proximate to the top portion of the cut hole towards a region proximate to and/or below the bottom of the cut hole, thereby preventing the damage associated with water being introduced behind the siding.

Abstract: A process is described for producing an alkylaromatic compound in a multistage reaction system comprising at least first and second series-connected alkylation reaction zones each containing an alkylation catalyst.

Abstract: A light olefin feed for an olefin utilization process is subjected to a water wash to remove water-soluble contaminants after which the water is separated from the olefin by coalescence separation at a low temperature, typically below 40° C. The coalescence separation technique is effective for separating the olefins from the water with its dissolved contaminants. If desired, a supplemental washing may be carried out by adding additional water to the feed/water mix after the initial wash step but before the coalescer in order to remove provide additional contaminant removal.

Abstract: A process for the alkylation of a benzene-containing refinery stream such as reformate with light refinery olefins which is capable of achieving high benzene conversion levels operates in a fixed bed of an MWW zeolite catalyst, preferably MCM-22, in single pass mode in the liquid phase at a relatively low to moderate temperatures with pressure maintained at a value adequate to ensure subcritical operation. High levels of benzene conversion with conversions of at least 90% and higher, e.g. 92% or 95% or even higher are achievable. A high octane product is produced, comprising mono-, di- and tri-alkylbenzenes with lesser levels of the tetra-substituted products. By operating with staged olefin injection, the end point of the alkylation product can be maintained at a low value while, at the same time, achieving high levels of benzene and olefin conversion.
