Monitoring flow resistance changes in solid bed reactor column - from pressure changes in initially standardised test flow gas

摘要

A basic flow of test gas through an upright solid bed reactor is produced by an adapter at the head or foot of the column and the pressure is used as a zero point in establishing the pressure changes during subsequent operation. The column may be closed off by an internal seal inflated by the test gas, possibly by use of an air-gun. In a variation, the granular filling, e.g., of catalyst particles, is held between the reactor column wall and an axial internal tubular protector for a thermal element. Air forms a suitable test gas. USE - Esp. for checking existence of undesired filling cavities which could affect reaction parameters.
