Technology

Flexicoking™, as a variation of Fluid Coking™, provides the options of partial or complete gasification of the Coke product to produce a Fuel Gas with some or no Fluid Coke in the product slate.

A gasifier is added for conversion of some or all Coke produced in the coker in reaction with Air and Steam to produce a Synthesis Gas.

The hot Coke particles from the combustor are circulated back to the coking reactor to provide the heat necessary for coking.

The distillate Products from the coker are sent to the fractionator, as is done in the fluid coking process.

On the gasifier outlet, after removing the fine particles from the gas by cyclones, the gas is cooled in a direct-contact cooler to condense the Sour Water and recover the Flexi-Gas.

The product gas can be used as Fuel Gas in the refinery.
