Abstract
1488131 Determining crystallisation temperature; measuring filterability ANTAR PETROLES DE L’ATLANTIQUE 19 Sept 1974 [19 Sept 1973] 40864/74 Headings G1D and G1S An apparatus for the continuous automatic determination of the filterability point of a liquid comprises:- (a) a liquid flow-path having an inlet and an outlet, (b) means to pass liquid through the flow-path at a constant flow-rate. (c) cooling means sufficient to reduce the temperature of said flow-path so that the pressure difference across said inlet and outlet reaches a first value corresponding to a first characteristic temperature, (d) means to measure the liquid pressure difference between said inlet and outlet, (e) liquid heating means in said circuit, to modify the temperature of the liquid as provided by said temperature cooling means, (f) means to switch on said liquid heating means when the pressure difference reaches said first value, (g) means to switch off said liquid heating means when the pressure difference reaches a second value which corresponds to a second characteristic temperature, and (h) means for continuously recording the temperature of the liquid in the flow-path; said first characteristic temperature corresponding to the filterability point and said second characteristic temperature being above said filterability point. A suitable apparatus is shown in Fig. 3 and comprises a housing 18 containing a cooling bath 14, cooling coil 15 and chamber 13. Liquid to be analyzed is pumped by 12 through chamber 13, which chamber contains filter 20. A thermosensitive element 21 registers the temperature of the liquid. A heating element 23 is connected to a differential pressure responsive means which itself is connected to the delivery side of the pump and outlet of chamber. An alternative form of apparatus is shown in Fig. 7 in which liquid to be analyzed flows through a metallic capillary tube 130, which tube is connected to electrical supply means and thus functions as a heating element. Temperature recording device 122 and differential pressure responsive means 125 are provided.
