Abstract: <PICT:0859500/III/1> In apparatus for controlling the free acid or alkali content of liquids in chemical processing, the liquid to be controlled is arranged to flow from a reaction vessel through a thermally insulated vessel containing a glass electrode and a reference electrode connected to an amplifier-milli voltmeter, the outside of the reference electrode being provided with a jacket in which temperature controlling fluid can flow.  In the apparatus shown, ammonium sulphate is prepared in a reaction vessel 1. The liquid is sampled by being forced by steam from a pipe 6 controlled by a valve 9, up a pipe 4 into the test vessel 12.  The steam is removed in a separator 10 and flows via a pipe 21 into a jacket surrounding the outlet pipe 20.  The test vessel 12 is provided with a vacuum jacket 17 and thermal insulation 18.  The tested liquid is allowed to return to the vessel 1 via pipe 20.  The pH is determined by means of a glass electrode 15 and calomel reference electrode 16, surrounded by a water jacket 16a.  A sampling outlet 24 is provided. The amplifier may be linked to valves for regulating the addition of reagents to the vessel 1 to provide fully automatic control.  The output of the test vessel 12 may alternatively be stored or flow to waste.  In alternative arrangements the test liquid may be gravity fed from vessel 1. The inlet and outlets of vessel 12 may be at the sides of the vessel.  The outlet 13 may then take the form of an upwardly directed S-bend pipe vented at its highest point.  The whole system may be lagged to prevent blockage due to crystallization.
