Abstract

Material withdrawal apparatus and methods and systems of regulating material inventory in one or more units are provided. A material withdrawal apparatus includes a heat exchanger and a sensor. The heat exchanger includes a material inlet, material outlet, cooling fluid inlet, and cooling fluid outlet. The material inlet is coupled to the unit and the sensor is coupled to the heat exchanger to provide a metric indicative of the temperature at the material inlet; material outlet; cooling fluid inlet and cooling fluid outlet. Another embodiment of a material withdrawal apparatus includes a vessel having an outer wall, liner, fill port, and a discharge port. The liner at least partially covers the inner surface of the outer wall. The fill port and discharge port are defined in the vessel and the fill port is configured to receive withdrawn material from at least a unit. Other embodiments provide methods of withdrawing or regulating material in a unit.

Description

technical field [0001] Embodiments of the invention generally relate to a material extraction apparatus and such a method. In particular, the invention relates to metering and extraction from one or more fluid catalytic cracking (FCC) units and one or more non-FCC units such as acrylonitrile manufacturing units, pyridine and its derivatives manufacturing units and other industrial processes, etc. Material extraction apparatus and methods for one or more materials. Background technique [0002] figure 1 is a simplified overview of a conventional fluid catalytic cracking system 130 . Fluid catalytic cracking system 130 generally includes fluid catalytic cracking (FCC) unit 110 coupled to catalyst injection system 100 , petroleum feedstock source 104 , exhaust system 114 , and distillation system 116 . [0003] FCC unit 110 includes regenerator 150 and reactor 152 . Reactor 152 primarily provides a site for catalytic cracking reactions of petroleum feedstocks and transports...
