Title: Detector for Detecting the End Point in Cloud Point Determination and an Apparatus Comprising It
Inventor: PRUVOT EUGENE
IPC: G01N21/27
Filed: 1966-09-27
Abstract: 1,197,568. Photo-electric cloud point determination. BRITISH PETROLEUM CO. Ltd. Aug.11, 1967 [Sept. 27, 1966], No.42987/66. Heading G1A. In cloud point determination, photo-electric apparatus is used to detect the first precipitation of solid material in a liquid sample during cooling of the sample. A pair of light guides are arranged so that a beam of light is projected into a particular small volume of the sample by the first guide and light from this volume is directed by the second guide to a photo-electric sensor such that a reduction is this sensed light intensity indicates formation of a precipitate. The apparatus may be used to determine the cloud point of wax in petroleum oil. The oil is cooled until the photo-electric apparatus detects formation of wax. This causes the coiling to be automatically reversed to prevent further unnecessary cooling. A recorder, plotting the temperature changes in the sample, provides a permanent record of the cloud point i.e. the temperature at which the first solid formation appeared, indicated by the point at which the curve changes in direction. The photo-electric apparatus comprises a lamp 14, first and second light guides 10, 11 and a photo-resistor 15, monitoring the light reflected off the bottom of sample container 40 and passing through the second guide and photo-resistor 16 detecting the intensity of the lamp. This apparatus is mounted on a lid 18 which can be placed in position over sample container 40. The container fits into an aluminium block 32 cooled by thermoelectric modules 35, supplied by power source 36. The photo-resistors 15, 16 are connected in a bridge circuit, Fig.3 (not shown), which feeds a milliammeter (26) or a Schmitt trigger (28). The circuit includes a potentiometer by which the meter can be zeroed when the lamp 14 is switched off. A screw 17 can be used to equalize the intensities at photo-cells 16, 15. Also the lamp output can be adjusted so that the intensity at the photo-cells is standardized. In operation, electro-magnetic valves 43, 44 are operated to introduce a sample. Cooling is started. When the cloud point is reached and precipitation detected, the trigger 28 is switched and causes reversal of the cooling operation and opening of the valves to introduce a fresh sample. A thermojunction 20 whose wires are attached to light guides 10, 11 monitors the temperature throughout and this is recorded at 33. This may be linked to the trigger 28 so as to fire when the temperature reaches a pre-set low level, to prevent abnormally low cloud point samples stopping continued operation.
