Abstract
A method is provided for quenching a slurry in a slurry vessel of slurry phase apparatus which comprises a gas distributor arranged to inject a gas into the slurry at a predetermined level, and an apertured solid particles support below the level at which the gas distributor is disposed to inject the gas. The method includes introducing a quenching liquid into the slurry vessel below the apertured support and passing the quenching liquid into the slurry through the apertures of the apertured support.
Claims5
A method of quenching a slurry of solid catalyst particles suspended in a liquid in a slurry vessel of slurry phase apparatus which comprises a gas distributor arranged to inject a gas into the slurry at a predetermined level, and an apertured solid particles support below the level at which the gas distributor is disposed to inject the gas, during interruption of gas flow through the gas distributor, the method including introducing a quenching liquid into the slurry vessel below the apertured support and passing the quenching liquid into the slurry through the apertures of the apertured support, thereby to quench exothermic reactions taking place in a bottom region of the slurry vessel catalysed by solid catalyst settled on the apertured solid particles support and to assist with re-suspension of catalyst particles.
