Optimal Organization of Furnace Systems at Oil Refineries

详细

The system considered in the present study consists of a heating furnace and a multipass recuperative heat exchanger for air preheating. Process design ensured the coordinated operation of this system by applying a basis of a probabilistic and informational approach to the organization of industrial systems. It proves optimal to increase the thermal load on the recuperative heat exchanger and decrease the thermal load on the furnace, without changing the overall heating parameters. Exergy analysis was used to validate the proposed solution and it was shown that the total exergy loss in a system with a heating furnace and a recuperative heat exchanger decreases in for recommended operating conditions. This results in fuel economy.
