An exhaust steam stream having an absolute pressure from 200 kPa to 1,050 kPa and shaft power are produced from an extraction turbine and/or a back-pressure turbine. The exhaust steam stream can be supplied to an amine regenerator of an amine COseparation process. The shaft power can be utilized to drive equipment in a hydrocarbon processing plant such as an olefins production plant.

Amine COseparation process integrated with hydrocarbons processing

The invention relates to Chydrocarbon conversion. More particularly, the invention relates to separating a vapor phase product and a liquid phase product from a heated mixture that includes steam and Chydrocarbons, catalytically cracking the liquid phase product and steam cracking the vapor phase product.

Process for Chydrocarbon conversion

An H-rich fuel gas production plant comprising a syngas production unit can be advantageously integrated with an olefins production plant comprising a steam cracker in at least one of the following: (i) fuel gas supply and consumption; (ii) feed supply and consumption; and (iii) steam supply and consumption, to achieve considerable savings in capital and operational costs, enhanced energy efficiency, and reduced COemissions, compared to operating the plants separately.
