Abstract
A process for improving flow properties of crude may include processing a first crude stream, which may in turn include cracking the first crude stream with fresh catalyst to form a cracked stream and spent catalyst, and then mixed with an unprocessed second stream. The spent catalyst may be regenerated to form fresh catalyst, which may then be recycled. At least part of the cracked stream may be mixed with a second crude stream. A ratio of the second crude stream to the first crude stream may be between about 0.5:1 and about 9:1. A ratio of part of the cracked stream to add to the second crude stream may be selected to achieve a API gravity of at least about 18. The first crude stream may be heated and stripped before being cracked.
