UOP and IFP reforming regeneration technologies
Thread Content
Hello everyone, what do the hot cycle for regenerated gas used in UOP and the cold cycle used in IFP mean? Both have air-cooled fans. Thank you.
The coking gas from the UOP regenerator enters the cycle in a hot state after leaving the regenerator; under normal conditions, this gas only needs to be cooled to the inlet temperature for coking before it can be sent back to the regenerator； The gas resulting from the burning of IFP passes out of the regenerator, is cooled to normal temperature via a heat exchanger and a water cooler, and then returns to the regenerator after being washed with alkali and dried. The UOP coking gas cycle operates in a hot and non-dried state, placing high demands on equipment and pipelines ； The IFP coking gas is a cold and dry gas, requiring low specifications for the materials of equipment and pipelines. The regeneration gas circulation is driven by fans (compressors).
