Abstract

1459909 Automatic analysis of flowing twophase mixtures ENTREPRISE DE RECHERCHES ET D’ACTIVITES PETROLIERES ELF 17 Sept 1974 [25 Sept 1973] 40484/74 Heading G1B A device for automatic analysis by mass spectrometry of two-phase mixtures which flow continuously through main pipes 2, 4 in for example a cracking plant comprises pipes 18, 22 &c. constituting a plurality of primary loops Bi (B 1 , B 2 shown), each of the primary loops being connected to a different one of the main pipes and to a recycling circuit in the direction of 27, each loop being fitted with a flow regulating valve 6, 10 and a flowmeter 8, 12 in series, the primary loops being traced, pipes Ti each connecting a branch point in a primary loop Bi to a pneumatic valve Vj (30 as shown) through a dust filter 26, 28 and a needle valve 32, 34 for regulating the flow-rate, the pneumatic valve(s) each for operably connecting one of the pipes Ti to one end of a further traced pipe T’, a sampling cell 40 at the other end of pipe T’, a sampling pipe T» for connecting one outlet of the cell 40 to the recycle circuit through a delivery valve V’ and a flowmeter 42 in series, means 46 for measuring the pressure in the cell 40, means for regulating the pressure in the cell by regulating the opening of valve V’ in response to a difference in pressure between the pressure measured by 46 and a reference pressure, a further traced pipe for connecting cell 40 to a further pneumatic valve V», a traced capillary tube T»‘ for connecting valve V» to a chamber E, pumping means 58, 60 for creating a vacuum within chamber E, a pipe for connecting chamber E to the ionization chamber 62 of a mass spectrometer, electronic means (not shown) for simultaneously initiating the application of voltage to the acceleration electrodes of the mass spectrometer and the opening of the pneumatic valve V», and means for initiating the selective opening of the valves Vj. The pipe «tracing» may comprise electrical resistance heating wire or a steam-fed copper pipe wound around the pipe to be traced, or a steam-fed sleeve concentric with the pipe. Fig. 3 (not shown) relates to the arrangement of eight pneumatic valves connectable in series, each valve having an inlet connected to one of a series of eight pipes carrying mixture to be analyzed, the valves being selectively operated by respective pairs of electrovalves, each pair of electrovalves being operable to connect one of the two inputs of the valve to the valve output.
