US Patent:

20210371757, Dec 2, 2021

Filed:

Aug 12, 2021

Appl. No.:

17/400374

Inventors:

Jorge Javier Vazquez - Houston TX, US
Surajit Dasgupta - Sugar Land TX, US
Michael Tallman - Houston TX, US
Priyesh Harilal Thakker - Houston TX, US

Assignee:

KELLOGG BROWN & ROOT LLC - Houston TX

International Classification:

C10G 11/18
B01J 8/18
B01J 8/22

Abstract:

An advanced regulatory controller for a converter of a catalytic olefins unit is disclosed. A Fluid Catalytic Cracking (FCC) type converter (i.e., reactor-regenerator) is combined with an ethylene style cold-end for product recovery. The regulatory controller operates using an Advanced Regulatory Control (ARC) application using variables, such as a controlled variable, four disturbance variables, associated variable, and a manipulated variable. The ARC application manipulates fuel oil or tail gas flow to a regenerator in response to an expected future steady state value of a regenerator bed temperature resulting from changes in the values of a selected set of the variables.
