Title: Process and apparatus for cooling gases
IPC: F25J5/00
Filed: 1964-08-20
Abstract: 1,026,265. Cold separation of gas mixtures. LINDE A.G. Aug. 20, 1964 [Aug. 21, 1963], No. 34006/64. Heading F4P. Each of at least three cyclically interchangeable regenerators undergoes a warm period during which compressed gas passing therethrough is cooled, a subsequent cold period during which cold gas at a lower pressure passing therethrough is warmed and an additional period immediately following the warm period and during which residual compressed gas is withdrawn through either the cold or warm end and used usefully. As shown, compressed coke oven gas from a supply line 5, Fig. 1(a) (not shown), is cooled in a regenerator 1, thereby depositing condensible constituents including ethylene and the so purified coke oven gas at a lower pressure is passed through regenerator 4 undergoing the cold period and through a discharge line 7. Residual gas in regenerator 2 which in the previous period was being warmed by passage of coke oven gas is withdrawn through lines 10, 20 and 11 including a regulating valve 18 and a check valve 19 and passed through a regenerator 3 to free it from deposited impurities and which latter are forced by a vacuum pump 8 into a crude ethylene container 9. The cold requirements of the system are met by refrigeration coils 21. After the first changeover regenerator 4 undergoes the warm period, regenerator 1 the additional period, regenerator 2 the rinsing period and regenerator 3 the cold period after three such changes the cycle recommences. In a modification, residual coke oven gas withdrawn during the additional period is added to purified gas being passed to the regenerator undergoing the cold period. In a further modification, residual gas is withdrawn from the warm end of the regenerator and is compressed and added to the crude gas feed to the regenerator in the warm period. In a further modification, the additional and rinsing periods are combined. In a still further embodiment included in a conventional twostage air rectification plant the residual compressed air is withdrawn from the cold end of the regenerator during the whole of the additional period thereof and is expanded through a throttle valve into the low pressure column at a uniform flow rate.

A continuous process for the production of a phosphate containing material comprises (i) acidulating phosphate rock with nitric acid (or a mixture thereof with e.g. sulphuric and/or phosphoric acid), (ii) simultaneously or subsequently adding (NH 4 ) 2 SO 4 , NH 4 HSO 4  or KHSO 4  to the reaction mixture in an amount of not less than 0À5 mole per mole of P 2 O 5  in the rock and at a rate such that dissolved sulphate concentration in the liquid phase is maintained in the range 0À5-4À0 wt. per cent, the addition being effected at above 60‹ C., and (iii) continuously removing the resulting acidic slurry containing precipitated calcium sulphate from the reaction system. This slurry is desirably neutralized (with or without prior removal by filtration of the calcium sulphate) e.g. with ammonia, an ammoniating solution, potassium carbonate or potassium hydroxide, and the product dried and/or granulated to produce a solid neutral fertilizer. The acidulation and sulphate addition may be performed in a multiple tank reaction system (cf. Specification 954,424). In the sulphate addition stage the calcium sulphate precipitates as gypsum between 60 and 90‹ C. and as hemihydrate or anhydrite at higher temperatures. In the preparation of fertilizers by the above method wherein the precipitated calcium sulphate is filtered off, sulphuric acid may be added to the reaction mixture prior to filtration and/or additional nitric acid or phosphoric acid after the filtration.
