OPTIMIZATION OF KADUNA REFINERY AND PETROCHEMICAL COMPANY (KRPC) CRUDE DISTILLATION UNIT I (CDU I) USING HYSYS

Abstract

The optimization of chemical processes has attracted attention because, in the face of growing competition, it is a natural choice for reducing production costs, improving product quality, meeting safety requirements or environmental regulations. Optimization of crude distillation column of Kaduna Refinery and Petrochemical Company by computer simulation (HYSYS) has been carried out. The optimization technique used is Sequential Quadratic Programming (SQP) optimization technique .. The column was operated with better performance while keeping the product quality constraints within the specified limits. The optimization objective function is Naphtha product volume flow rate. The optimization carried out shows that the plant has a profit analysis ofW24,457,543.43, while the base case has a profit analysis of W22,375,349. 71 . The constraint variables used for the optimization are the Condenser and Trim duty. The optimization also shows that Naphtha product volume flow rate is 228.6m3/h while that of the base case is 200.3m3/h respectively; hence the optimum value of the Naphtha product volume flowrate is 228.6m3/h.
