Abstract
An apparatus and method for introducing a predetermined volume of suspension into a reactor from a storage vessel. According to the invention the storage vessel is connected via a first conduit to an intermediate vessel which is in turn connected to a feed vessel via a second conduit, the feed vessel is connected via a third conduit to the reactor, each of the first, second and third conduits, is provided with a shut-off valve, the vessels, conduits and valves being so arranged that the suspension can be transferred by gravity from the storage vessel to the intermediate vessel and from the intermediate vessel to the feed vessel and can be transferred from the feed vessel to the reactor by gravity and/or the effect of pressure difference between the feed vessel and the reactor. The present invention also relates to a process for introducing a predetermined volume of suspension into a reactor using the apparatus.
