Abstract: 1521813 Fluid regulation NATIONAL FORGE CO 5 May 1976 [6 May 1975] 18454/76 Heading G3H [Also in Division B5] An isostatic moulding press within which preheated powdered material is compacted at elevated temperature by fluid-pressure e.g. at up to 50,000 p.s.i., comprises heating elements 22 for heating an area 18 of the press in which compaction is effected, within a surrounding mantle 16 providing heat insulation from the outer surrounding wall 11 of the press from which it is spaced by an area 20. During fluid pressurization or depressurization of the press, damage to the mantle 16 arising from unequal fluid pressures in the areas 18, 20, is prevented by fluid communication with each area being effected by separate ports 26, 24 which are each connected to a pressure sensitive fluid control valve means acting to maintain the pressures equal. Pressurization is effected by a pressurization valve 50, having outlet ports 64, 66, respectively connected to the ports 24, 26, and communicating with a fluid inlet port 54, via a bore 53 in which a piston 55 is axially displaceable by pressure differences between the ports 64, 66, so that a displacement of the piston 55 towards the lower pressure port causes flow restrictive annuli around the piston to be respectively shortened to decrease the pressure drop to the lower pressure port, and lengthened to increase the pressure drop to the high pressure port until the pressures in ports 64, 66 are equal. De-pressurization is effected by a depressurization valve 32, having inlet ports 38, 39 respectively connected to the ports 24, 26, and communicating with a fluid outlet port 36, via a bore 37 in which a piston 35 is axially displaceable by pressure differences between the ports 38, 39, so that a higher pressure in one port 38 causes displacement of the piston towards the other and a respective shortening and lengthening of a flow restrictive annulus around the piston 35 which acts to respectively decrease and increase the pressure drops until the pressures in the ports 38, 39, are equal. During compaction either valve may be employed to maintain equal pressure in the areas 20, 18, by closing one of the ports 36 or 54.

At least 5% reducing agent, e.g. H 2 S, CO or H 2 , may be present in the regenerating gas.  In the apparatus of Figure 2 adsorbent is circulated through adsorption column 20, regeneration column 21 and cooling column 22. Residual gas, e.g. claus effluent enters the bottom of column 20, is adsorbed at below 150C and the reaction proceeds, purified gas leaving the top of the column. Regenerating gas, e.g. No and H 2 S, from furnace 26 is injected into the bottom of column 21 and keeps it between 200C and 350C. A mixture of regenerating gas and S vapour passes into condenser 29 and liquid S flows into tank 34. The regenerating gas then enters separating device 32 where vesicular sulphur condenses and passes to tank 34 and the gas returns to furnace 26. The adsorbent is cooled and rehydrated at approximately 150C in column 22 by blowing with a mixture of N 2  and water vapour.  In the apparatus of Figure 3 (not shown) each column (51, 52 or 53) is used in turn for adsorption, regeneration and cooling. In the apparatus of Figure 1 (not shown) the columns (1, 2, 3) are regenerated in sequence, two columns being used for adsorption while the third is subjected to regeneration and cooling.  The gas can be contacted with the adsorbent using fixed bed, mobile bed or fluidised bed techniques and with parallel or counter flow currents.
