Abstract
A method and system for providing heat to a chemical conversion process is advantageously employed in the production of olefin by the catalytic dehydrogenation of a corresponding hydrocarbon. The catalytic dehydrogenation process employs diluent steam operating at a steam to oil ratio which can be 1.0 or below and relatively low steam superheater furnace temperature. The process and system are advantageously employed for the production of styrene by the catalytic dehydrogenation of ethylbenzene.
Claims10
A method for providing heat to a chemical conversion process stream containing at least one chemical reactant, comprising the steps of:
- a) superheating a heat transfer fluid;
- b) transferring heat from the superheated heat transfer fluid to a process stream;
- c) dividing at least some of the heat transfer fluid after transferring heat in step b into a first portion and a second portion;
- d) pressurizing the first portion of heat transfer fluid;
- e) recycling the pressurized first portion of heat transfer fluid to superheating step (a);
- and,
- f) introducing the second portion of the heat transfer fluid into the process stream.
