Abstract

See full text

A process for capturing carbon dioxide includes the steps of mixing a hydrogen stream and a feedstock stream to produce a mixed stream, wherein the feedstock stream includes hydrocarbons, reacting the hydrocarbons and the hydrogen in the primary reactor of the hydroprocessing unit to produce a hydroprocessing product stream and a carbon dioxide stream, wherein the hydroprocessing product stream includes light products, wherein the hydroprocessing unit is further configured to produce ammonium bisulfide, collecting the ammonium bisulfide in the water to produce a sour water, processing the sour water in the waste water unit to produce an ammonia stream, a hydrogen sulfide stream, and a stripped water stream, introducing the ammonia stream to a carbon dioxide recovery system, and separating carbon dioxide from the carbon dioxide stream using the ammonia in the ammonia stream to produce a carbon dioxide product.
