Furnace Convection Section Model facilitates 20% rise in Plant Capacity

Decoking of pyrolysis furnaces at a major ethylene complex posed a constraint in ethylene production. The slowdown affected the supply & sales schedule significantly. Root cause analysis of the symptoms exposed possible underutilization of furnaces. Analysis of furnace  maintenance/ operation history, onsite load tests, micromanagement and a robust model of the convection section of the furnace helped realize 20% increment in the throughput for the ethylene complex.
