Abstract
The present invention provides a process and apparatus for feeding powders such as fine, cohesive, or powdery particulate materials from a low pressure system to a high pressure system. There is provided in a preferred embodiment a process and apparatus of pressurizing and feeding carbon black fluff to a polymerization reactor, particularly a gas phase fluidized polymerization reactor to provide for a close-coupling of a carbon black reactor to a polymerization reactor.
