Methods and apparatus for separating particulates from a particulate-fluid mixture

A method for separating particulates from a carrier fluid, comprising:

• introducing a particulate-fluid mixture into an inlet of a separator, the separator comprising:
• a separation section having at least one wall, a first end, a second end and an inner metal surface that is exposed to an internal volume of the separation section;
• a fluid discharge outlet in fluid communication with the internal volume at the first end;
• a particulate discharge outlet in fluid communication with the internal volume at the second end;
• and
• an inlet in fluid communication with the internal volume, wherein the inlet is disposed intermediate the first end and the second end;
• separating the particulate-fluid mixture to provide a fluid product having a reduced particulate concentration relative to the particulate-fluid mixture and a particulate product;
• recovering the fluid product from the fluid discharge outlet;
• and
• recovering the particulate product from the particulate discharge outlet.

A fluid catalytic cracking system, comprising:

• a fluidized catalytic cracking riser having a product outlet in fluid communication with an inlet to a separator, wherein the separator comprises:
• a separation section having at least one wall, a first end, a second end and an inner metal surface that is exposed to an internal volume of the separation section;
• a fluid discharge outlet in fluid communication with the internal volume at the first end;
• a particulate discharge outlet in fluid communication with the internal volume at the second end, wherein the inlet to the separator is in fluid communication with the internal volume, and wherein the inlet is disposed intermediate the first end and the second end;
• and
• a regenerator in fluid communication with the particulate discharge outlet.
