Patent ID: 8888992

Claim:
A process for improving flow properties of crude, comprising: processing a first crude stream including directing said first crude stream to a feed zone of a fractionator column, directing fractionator product to a riser, cracking said fractionator product of said first crude stream with fresh catalyst to form a cracked stream and spent catalyst at an oil field; separating said cracked stream from said spent catalyst; regenerating said spent catalyst to form said fresh catalyst and regeneration flue gas; recycling said fresh catalyst; directing said cracked stream to a product zone of said fractionator column, and said feed zone and said product zone are separated by a partition positioned to isolate the feed zone from the product zone; mixing at least part of said cracked stream with a second crude stream; and transporting a mixture of said cracked stream and said second crude stream over 20 miles from said oil field where it was mixed in a pipeline to a refinery for further processing.
