Title: Process for deodorizing spent caustic alkali solutions from a petroleum refinery process
Inventor: JONES PATRICK ROGER HARTLEY
IPC: C10G19/08
Filed: 1956-06-12
Abstract: Spent sodium hydroxide solution from a petroleum refinery process is contacted with sulphur dioxide- and oxygen-containing gas produced by the combustion of hydrogen sulphide-containing gas with an excess of air, so as to reduce the pH of the solution to a value below 8.5, preferably a value of 7.5-8.5, and stripping gas is passed through the solution so as to reduce the odour thereof.  The stripping gas may be said sulphur dioxide-containing combustion product gas and stripping therewith may be effected during and/or after treatment with such gas for the purpose of reducing the pH thereof.  The hydrogen sulphide-containing gas may be a by-product from a cracking or desulphurization petroleum refinery process.  In one embodiment (Fig. 1, not shown) hot combustion product gas containing sulphur dioxide and excess air is passed upward at a temperature of 210 DEG F. through a combined pH-reduction and stripping tower, down which is passed spent solution at a temperature of 200 DEG  F., a portion of said solution having been preheated by indirect heat exchange in the combustion step so as to produce a solution of sodium sulphite and sulphate.  In another embodiment (Fig. 2, not shown), combustion is effected beneath the surface of the spent solution thereby effecting neutralization and partial stripping, combustion product gas and solution being passed to a tower as in the first embodiment for completion of the stripping.ALSO:Spent sodium hydroxide solution from a petroleum refinery process is contacted with sulphur dioxide- and oxygen-containing gas produced by the combustion of hydrogen sulphide-containing gas with an excess of air, so as to reduce the pH of the solution to a value below 8,5, preferably a value of 7,5-8,5, and stripping gas is passed through the solution so as to reduce the odour thereof.

Filed: 1955-06-28
Abstract: 795,676. Drafting fibres. SKF KUGELLAGERFABRIKEN GES. June 28, 1955 [June 30, 1954], No. 18687/55. Class 120(2) Slivers in which at least half of the fibres are of substantially the same known length are drafted by means of a pair of rollers, one of which has its circumference equal to the fibre length or to a fraction of the fibre length obtained by dividing the length by a whole number. Irregularities in yarn due to periodic displacement of the drafting roller nip caused, e.g. by roller vibration or rollers not being ground true, are said to be prevented by this means. Preferably, one of the top rollers is selected to be of the desired size and the associated bottom roller is of much greater diameter. For worsted yarn fibres; the circumference of the smaller roller will usually be less than 110 m.m. and for staple synthentic fibres or short staple cotton the circumference of the smaller roller will usually be less than 60 m.m. In the embodiment illustrated, a top drafting rolling 35 has its circumference equal to the length or average length of the fibres in the sliver 36. The circumference of the bottom roller 36 is a multiple of the top roller 35 circumference.
