Abstract
Official abstract text for this publication.
A method of revamping vertical converters having a bolt-on flanged pressure shell extension for housing an internal heat exchanger is performed by replacing an existing pressure shell extension with a larger pressure shell extension for housing a plurality of internal heat exchangers.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of revamping vertical converters having an existing bolt-on flanged pressure shell extension for housing an internal heat exchanger, the method comprising: replacing the existing bolt-on pressure shell extension with a larger pressure shell extension having a housing in which a plurality of internal heat exchangers are positioned, wherein an existing feed-effluent exchanger or a replacement feed-effluent exchanger is housed in the larger pressure shell extension. 2. The method of claim 1 , wherein the larger pressure shell extension comprises one or more converter inlet nozzles and a converter outlet nozzle. 3. The method of claim 1 , wherein the larger pressure shell extension has a substantially similar diameter as a diameter of the existing bolt-on pressure shell extension and greater length than the existing bolt-on pressure shell extension. 4. The method of claim 1 , wherein the larger pressure shell extension comprises an upper section of larger diameter than the existing bolt-on pressure shell extension and a lower flanged section of smaller diameter than the upper section to match with an existing main converter pressure shell flange. 5. The method of claim 1 , wherein one or more inter-bed heat exchangers used for cooling reactant gases from a catalyst bed are housed in the larger pressure shell extension. 6. The method of claim 1 , further comprising positioning the plurality of internal heat exchangers in the larger pressure shell extension. 7. The method of claim 1 , wherein the larger pressure shell extension further houses one or more intercoolers.
