摘要： A device (10) for measuring the flow rate of a fluid flowing in a pipe, especially for a transaction between a hydrocarbon supplier and a hydrocarbon purchaser is provided. The device (10) has a cylindrical body (11) to be interposed between two sections of the pipe. Ultrasound-beam transducers (15) are mounted on the main body (11) and intended to measure at least a rate of movement of the fluid stream as this flows through the device (10). At least one converter converts the signals emitted by the transducers into a flow rate signal. The transducers (15) are mounted and uniformly distributed on two coaxial parallel rings (12, 13). The transducers (15) of a first ring (12) are angularly offset relative to the transducers of the second ring (13).

摘要： Acrylic acid obtained by catalytic oxidation of propylene, extracted by countercurrent washing of the reaction gases which at least one hydrophobic heavy solvent in an extraction column (C1) is purified. To this end, a distillation of the stream (5) obtained at the bottom of the column (C1) is conducted in a column (C3) so as to obtain a very pure acrylic acid stream (6) at the top of the column (C3), allowing acrylic acid to pass at the bottom (7); the bottom stream (7) is conveyed as feed into the lower part of a distillation column (C4) from which a stream (9) rich in maleic anhydride and impurities of boiling temperatures situated between that of acrylic acid and that of the heavy solvent is drawn off sideways on a tray situated between the feed and the top of the column; a stream (8) rich in acrylic acid, which is returned as feed to the column (C3) is distilled at the top of the column (C4); and a stream (1) containing heavy solvent and heavy impurities, which is recycled to the top of the column (C1), is recovered at the bottom of the column (C4).
