Environmental Appraisal Report

Coke Dry Quenching (CDQ) is a system where the red hot coke brought out of coke ovens is cooled with cold inert gas in the CDQ shaft. The cold inert gas exchanges heat with the red hot coke to cool the red coke. The heated inert gas is utilized in Waste Heat Recovery Boiler (WHRB) to generate steam or electric power.

Catalyst recycle in slurry-phase residue upgrading

The application of slurry-phase hydroconversion to upgrade residue oil derived from the Canadian oilsands (CLVR) is hindered by the cost of the catalyst, in part because the catalyst is used once-through before being discarded as part of the solid product (coke). The goal of the present study was to assess the potential of recycling the slurry-phase catalyst under high residue conversion ...
