Abstract
An apparatus for the transfer of solid particulate matter from a low pressure system to a high pressure system is presented. The apparatus simplifies the particle transfer process, and is useful for systems where solid catalyst particles are cycled through a reactor and a regenerator.
Claims11
An apparatus for transferring solid particulate matter from a low pressure vessel to a high pressure vessel and removal of contaminants transfer with the solids by purging the solid particles at the same time comprising:
- a flow control vessel disposed between and in fluid communication through a solids transfer line with the low pressure vessel and the high pressure vessel;
- a surge function disposed between and in fluid communication through a solids transfer line with the flow control vessel and the high pressure vessel;
- a first solid particle transfer valve disposed between the flow control vessel and the low pressure vessel;
- a high pressure inert gas source having a fluid connection between the flow control vessel and the surge function, delivered through a pressure control valve;
- a second solid particle transfer valve disposed between the flow control vessel and the high pressure inert gas source;
- and
- a third solid particle transfer valve disposed between the surge hopper and the high pressure inert gas source.
