Abstract
A method of removing an obstruction of coke built up in a riser of a fluid catalytic converter and of cleaning the riser involves using a suspended centralizer and narrowly angled nozzles for first hydroblasting a drainage orifice in the obstruction, adjusting guide arms and manipulating the suspended apparatus to allow enlargement of the orifice, further adjusting the guide arms and enlarging the angles of the nozzles to work the remaining coke built up.
