Continuously homogeneous suspension from which specific quantity - periodically removed

摘要

The suspension is kept continuously in motion in a storage vessel and the specified quantity removed via a lock chamber which is washed clean after each metering operation, the improvement whereby a continuous circulation of the suspension outside the storage vessel is set up by means of a gas-lift, such that between metering periods the suspension runs through the lock chamber, and during metering flows through a pipe by-passing the lock chamber, pref. using the gas above the liquid in the storage vessel for the gas-lift It is applicable to catalyst suspension e.g. TiCl3 suspended in benzene.
