Abstract: 1328357 Phosphoric acid; calcium sulphate PRODUITS CHEMIQUES PECHINEYSAINT-GOBAIN 28 Sept 1970 [30 Sept 1969] 46080/70 Heading C1A Phosphoric acid and calcium sulphate are manufactured by reacting calcium phosphate with sulphuric acid in a medium containing sulphuric acid or a mixture of sulphuric acid and phosphoric acid, separating of the calcium sulphate from the reaction medium in a separation zone, treating the calcium sulphate in the separation zone with an aqueous solution to change the state of hydration, without dispersing the calcium sulphate in the solution and washing the resulting calcium sulphate. The treating solution may be aqueous sulphuric acid and may be derived in part from the reaction medium and the phsophoric acid derived from the washing of the treated calcium sulphate. Calcium sulphate crystals of the state of hydration required after treatment with the treating solution may be added to the reaction medium as it is passed to the separation zone. In Examples 1 and 2 phosphate was treated with sulphuric acid and the gypsum separated from the resulting slurry of gypsum and phosphoric acid was treated with 50-80% H 2 SO 4  at 50 to 120 C. to form hemihydrate. In Examples 3, 4, 5 in which a slurry of hemihydrate and phosphoric acid was obtained, gypsum was produced by treating with aqueous sulphuric acid (200 g./l.) (Examples 4, 5) at 70 C. or anhydrite was produced by treating with a solution containing 80% H 2 SO 4  at 80 C. (Example 3).

Title: Computerized process and apparatus for use with a submerged arc electric furnace to produce metallurgical products
IPC: H05B7/156
Filed: 1971-10-05
Abstract: 1372073 Automatic control of arc furnaces UNION CARBIDE CORP 5 Oct 1971 [5 Oct 1970] 46211/71 Heading G3R The current in a submerged arc furnace is maintained at an optimum value by generating a control signal in dependence on measured current and electrode position, and using the signal to adjust the electrode within a given range. As shown, calcium carbide is produced in a furnace 302 with at least one hollow electrode 301 around which is packed a mixture of lime and carbon reducing material. Further reactants are supplied through the electrode to the reaction zone 303. The electrode current is continuously measured and combined with pre-set tolerance and current reference values to produce a signal which causes hydraulic pistons 307 to adjust the electrode position by small increments. The electrode tip position, which may be sensed by thermocouples, is compared with upper and lower limits, and if out of range, the reference current signal is modified, and the reactant feed is controlled until the position is again in the desired range. Electrode consumption is measured as a function of power generation and determines electrode slip using bands 310, 312  energized hydraulically. The current reference value is reduced during slip intervals. The temperature at a tap hole 309 is sensed by a pyrometer to give an indication of carbide quality, and deviations of the quality from a pre-determined value are corrected by regulation of reactant feed. Coolant water flow and pressure are sensed by meters 329, 330, 331 which actuate alarms if pre-set values are exceeded.
