Abstract
Systems for heating multi-tubular reactors are provided. Systems can include one or more reaction panels including multiple vertically-oriented reaction tubes, each including a catalyst bed, which can be located within a furnace. A burner system can provide a flue gas to the furnace, and the flue gas can enter one or more distribution chambers such flue gas in the distribution chambers does not contact the portion of the reaction tubes containing the catalyst bed. The flue gas can travel from the distribution chambers and through one or more convection chambers to flow co-currently with a feedstream within the reaction tubes.
Claims20
A system for heating a multi-tubular reactor with a flue gas, comprising:
- (a) one or more combustion chambers in fluid communication with a furnace;
- (b) one or more reaction panels comprising multiple vertically-oriented parallel reaction tubes disposed within the furnace, wherein at least a portion of each reaction tube comprises a catalyst bed;
- (c) one or more distribution chambers arranged such that flue gas within the distribution chambers does not contact the portion of the reaction tubes that comprises the catalyst beds;
- (d) one or more convection chambers arranged such that flue gas within the convection chambers contacts the portion of the reaction tubes that comprises the catalyst beds, wherein:
- i. the flue gas is generated within the one or more combustion chambers;
- ii. the flue gas enters the one or more distribution chambers;
- and
- iii. the flue gas exits through the distribution chambers and into the one or more convection chambers;
- wherein each distribution chamber has a closed bottom and an open top and is defined by at least two vertically-oriented guiding walls, and wherein each distribution chamber is disposed adjacent to at least one reaction panel.
