FLUID COKING PROCESS

摘要

IMPROVED FLUID COKING PROCESS An improved coking process wherein a heavy hydrocarbonaceous chargestock is partially converted to lower boiling products in a fired heater at temperatures up to, but not including, coking temperatures. The partially converted chargestock is then fed to the scrubbing zone of a fluid coker whereupon the products of conversion are stripped off along with the products from the coking zone of a fluid coking unit. The unconverted hydrocarbonaceous material from the scrubbing zone is fed to the coking zone.
