Title: Improvements in or relating to phosphoric acid, and derivatives thereof
IPC: B01D1/30
Filed: 1966-04-13
Abstract: 1,145,903. Phosphoric acid. OCCIDENTAL RESEARCH & ENG. Ltd. 13 April, 1966 [22 April, 1965], No. 16129/66. Heading C1A. Continuous concentration of phosphoric acid solution of less than 68% P 2 O 5  is carried out by evaporating the water from the solution in a submerged combustion evaporation zone. The solution is divided into several portions, at least one of which is in direct contact with hot gaseous combustion products and then with the remaining portions, and the recombined portions removed from the zone as a solution of preferred P<SP>2</SP>O 5  content of 72-79% of which 22- 65% is orthophosphoric acid, less than 44% pyrophosphoric acid and more than [(2À08 x % P 2 O 5 )-146À4]% of tripolyphosphoric acid. The ratio of tripolyto pyrophosphoric acid is not less than [0À0571 x % P 2 O 5 )-4À014]. The presence of tripolyphosphoric acid solubilizes all the metallic impurities present by chelating them, so that the impure phosphoric acid made by the wet-process method can be used as the original phosphoric acid solution. Ammoniation of the solution produces ammonium phosphate fertilizers; other fertilizers can be made by adding, for example, sulphuric acid, ammonium phosphate, ammonium nitrate, urea, other condensed phosphates and potassium salts.

Title: Improvements in or relating to the production of low carbon ferrochromium
IPC: C21D3/04
Filed: 1955-06-07
Abstract: High carbon ferro-chromium is decarburized by heating a charge comprising finely divided high carbon ferro-chromium and finely divided chromite ore under subatmospheric pressure at a temperature high enough to oxidize the carbon of the high carbon ferro-chromium and removing the oxide of carbon formed.  The high carbon ferro-chromium may contain 6-8 per cent carbon which may be reduced by the process to 0.01 per cent.  The chromite ore may be used raw or may be heat treated e.g. roasted or sintered.  The ferro-chromium and the chromite ore may be ground to pass a 200 mesh sieve and thoroughly mixed before being formed into briquettes with a binder, e.g. dextrin or sulphite liquor.  The briquettes may be dried and then heated in a vacuum, e.g. 110 microns, until there is no further reaction between carbon and oxygen.  Slag forming materials may be present and the briquettes may include a catalyst e.g. fluorspar. The low carbon ferro-chromium produced may be used as an addition in the manufacture of chromium steels.

Title: Improvements relating to the hydrofining of gas oils and to the hydroforming of naphthas
IPC: C10G45/00
Filed: 1944-08-28
Abstract: In the hydrofining of gas oil according to the process of Specification 588,765, i.e., at elevated temperature and pressure in the presence of a hydrofining catalyst, with sufficient hydrogen re-cycle to maintain vapour phase conditions, and with a velocity of feedstock maintained within the limits of .5 to 2.5 volumes of gas oil per volume of catalyst per hour, the hydrogen is derived from a naphtha hydroforming process.  This hydrogen contains a proportion of light hydrocarbons such as methane, ethane &c. which are absorbed by the gas oil.  The hydrogen recovered from the hydrofining process is therefore freer from light hydrocarbons and more efficient for the re-circulation to the naphtha hydroforming reaction zone for suppressing the carbon formation on the catalyst.  The hydrogen sulphide formed by the hydrofining process may be left in the hydrogen re-circulated to the naphtha hydroforming process or it may be removed such as by a soda wash.ALSO:In the hydrofining of gas oil according to the process of Specification 588,765, [Group III], i.e. at elevated temperature and pressure in the presence of a hydrofining catalyst, with sufficient hydrogen re-cycle to maintain vapour phase conditions, and with a velocity of feedstock maintained within the limits of .5 to 2.5 volumes of gas oil per volume of catalyst per hour, the hydrogen is derived from a naphtha hydroforming process.
