Apparatus for injecting a hydrocarbon feed

摘要

Device for injecting a charge of hydrocarbons into a catalytic cracking reactor comprising in particular an envelope (1), a principal inlet tube (3), and an inlet (2) for a gaseous auxiliary fluid. The principal inlet tube is divided inside the envelope into at least two secondary pipes (4) intended to divide the charge evenly, each secondary pipe opens upstream of a venturi-type element, and the gaseous auxiliary fluid is mixed with the charge in a mixing chamber at the inlet to the venturi. Application of the above device to the catalytic cracking of heavy charges of hydrocarbons.
