    Abstract: Fire resistant hydraulic fluid compositions comprising (a) one or more esters of polyhaloaromatic acids per se or in combination with (b) one or more hydraulic fluids independently selected from mineral oil, poly- alpha -olefins, alkylated aromatics, cycloaliphatics, esters of dibasic acids, polyol esters, polyglycols, silicones, silicate esters, phosphate esters, and halogenated compositions other than (a); a method for imparting fire resistant properties to known hydraulic fluids by adding one or more esters of polyhaloaromatic acids alone or combined; and the use of the inventive compositions as fire resistant hydraulic fluids. The fire resistant compositions may, optionally, contain one or more shear-stable polymers which have been found to increase the fire resistance of the hydraulic fluid composition.

    Abstract: A multiple, parallel packed column vaporizer (10) for vaporizing a chemical having a relatively low decomposition temperature includes a shell (12); a plurality of parallel, vertically oriented vaporization columns (34) arranged in the shell, each vaporization column having inner walls and upper (14) and lower (16) open ends; a distribution assembly (152) for distributing the chemical substantially equally to the open upper ends (14) of the vaporization columns (34), which flows downwardly therein; a fluid heat exchanger which heats the vaporization columns to provide the heat needed to vaporize the chemical therein; and a gas supply (132) which supplies the gas to the lower ends (16) of the vaporization columns (34) so that the chemical is vaporized and becomes entrained in the gas and is carried upwardly out of the vaporizer (10).
