Carbon-Energy Impact Analysis of Heavy Residue Gasification Plant Integration into Oil Refinery

A gasification plant may partially replace an industrial thermal and hydrogen production by polygenerating valuable products (hydrogen, power, steam) from low-value materials. Carbon energy analysis is one way of conceptually evaluating such processes. In this paper, the integration a heavy residue (HR) into mid-size oil refinery (5 million t per year crude processing rate) assessed via comparison electricity, natural gas consumption, CO2 emissions. The main purpose to reduce consumption currently used for at expense increased HR achieve reduction in Two case studies with different modes operation were compared base showing that annual 2280 GWh constant heat possible, accompanied slight increase electricity purchase 28 year. increases over 2800 refinery’s emissions more than 20% (up 350 kt year) as result, while, after incorporating external balance, decrease 460 can be achieved. This confirms plants within enterprises clusters has positive environmental impact supports idea converting material polygeneration plants. economics gasifier varying operations under real conditions remain explored.
