Title: Masses for protective and insulating purposes or the like
IPC: C08L91/06
Filed: 1933-02-15
Abstract: Chemically resistant materials which remain plastic between temperatures - 40 to 40 DEG  C. are combined with elastic materials in such a way that the resulting masses are relatively stable in shape and are elastic particularly in the direction of pull and plastic in the direction of pressure.  The masses may be employed for insulations of all kinds, as protection against rust, and as sealing compositions.  Examples of plastic materials are proto-paraffins such as are found in ozokerite and the residues of the distillation of petroleum and the like melting at about 50 DEG  C., and petroleum jelly melting at about 20 DEG  C., with or without the addition of soft bitumen melting at about 30 DEG  C. and chemically resistant fillers e.g. talc, heavy spar, china clay, slate and asbestos powder. The elastic material may be rubber or the like, vulcanized or unvulcanized.  A nucleus of the plastic material may be coated with the elastic material so that the entire mass has a somewhat ropelike structure or a laminated structure may be built up of layers of plastic and elastic materials.

Patent GB-847289-A (GB)
Title: Recovery of hydrocarbons from spent caustic
IPC: C10G19/08
Filed: 1958-02-13
Abstract: Hydrocarbons are obtained from acidic organic material dissolved as salts in spent aqueous caustic solution from the treatment of petroleum naphtha by recovering the acidic material as a water-insoluble oil and subjecting this to catalytic hydrogenation to obtain hydrocarbons.  The acidic materials are naphthenic acid, phenols, thiophenols and mercaptans.  The mercaptides in the caustic solution can be removed by boiling, steaming or oxidation to convert the mercaptides to insoluble disulphides.  Preferably, however, all materials are liberated together by acidification with SO2, CO2, flue gas or a mineral acid preferably sulphuric.  The gases can be used at 100-200 DEG F. and atmospheric pressure; if steam is also used the liberated materials are stripped overhead.  Temperatures of 70-130 DEG F. and pressures of 200-500 p.s.i.g. are more effective for the naphthenic acids.  Mineral acids above 0,1 N can be used at 70-150 DEG F.  The hydrogenation is performed with catalysts normally used in hydrofining, e.g. 5-15% molybdena on alumina, mixtures of 2-6% cobalt oxide and 6-15% molybdena or an equivalent amount of cobalt molybdate on alumina, nickel tungsten sulphide or molybdenum sulphide.  Preferred conditions are similar to those used in hydrofining operations, viz., 500-750 DEG F. p  100-1000 p.s.i.g., 0,1-16 vol./vol./hr., with 200-3500 SCF of hydrogen per barrel, the hydrogen consumption being 10-1000 SCF per barrel.  In an example spent caustic from the caustic treatment of a heavy catalytic naphtha and containing 23 volume per cent of acid oil was neutralised and the acid oil separated. Mercaptans were not present but were added to demonstrate that they are also effectively handled.  The oil (25 parts by volume) was diluted with a hydrofined naphtha (octane No. 46,1) (75 parts) and the mixture hydrofined over a cobalt molybdate-alumina catalyst at 650 DEG F., 400 p.s.i.g., 1 vol./vol./hr. with 1500 SCF of hydrogen per barrel to give a product containing 0,02 wt. per cent sulphur and 0,05 wt. per cent phenols with an octane number of 57,5.  This represents a conversion of 99% of sulphur compounds and 99,9% of phenols to hydrocarbons.

Title: Improvements relating to the manufacture of ammonium nitrilosulphonate
IPC: C01B21/096
Filed: 1951-02-28
Abstract: Ammonium nitrilosulphonate, which may be converted to ammonium sulphamate by hydrolysis, is obtained as a byproduct in the manufacture of ammonium hydroxylamine disulphonate by reacting sulphur dioxide with an aqueous solution of ammonium nitrite and ammonium bisulphite, or any other compound, e.g. ammonium hydroxide, yielding ammonium bisulphite with sulphur dioxide, by maintaining the pH- value of the reaction mixture initially between 5 and 7 and separating the precipitated ammonium nitrilosulphonate before the pH is reduced below this range. Sulphur dioxide-containing gas is supplied, in amount regulated to maintain the pH of the reaction liquor at 5.5-6, at 3 to packed reactor 1 countercurrent <PICT:0676956/III/1> to ammonium nitrite and hydroxide solution introduced at 2.  The liquor is drained to tank 6 and recycled through pump 8, cooler 10, and pipe 9 to reactor 1.  Part of the recycled liquor is drained off through pump 12 to filter 13 to separate precipitated ammonium nitrilosulphonate.  The filtrate passes to reactor 17 and passes therethrough, from distributor ring 16, countercurrent to sulphur dioxide-containing gas entering at 19 in amount regulated to give a pH of 3.5 in the resulting ammonium hydroxylamine disulphonate solution which is recovered and air blown to remove excess SO2.  Reactor 17 has packed pipes 18 surrounded by a refrigerant jacket.
