摘要:

AbstractThe pipeline transport of solids in the form of capsules appears to have advantages over the conventional slurry operation. One of the problems which must be faced, however, is the startup of a capsule pipeline which has been temporarily shut down. Data are presented for the fluid velocity and pressure gradient which were required to initiate movement of 3‐in. long cylindrical capsules equally spaced at various linear concentrations on the bottom of a 1‐in. diameter model pipeline. The specific gravity of the capsules ranged from 1.40 to 8.44 and capsule diameter to pipe diameter ratio ranged from 0.247 to 0.868.For a given set of capsules, the critical fluid velocity passed through a minimum, and the critical pressure gradient passed through a maximum, at a linear concentration of about 60–65%. The critical power consumption, however, was only slightly dependent on linear concentration. For a given linear concentration, the critical power requirement increased concomitantly with capsule specific gr

摘要:

AbstractThe influence of reactant segregation and of the rate of reactant mixing on fast homogeneous chemical reaction rates is considered and a computer model presented to simulate the effect of mixing within a tubular reactor fed by two segregated but miscible streams.Results obtained from use of the model are discussed.
