Figure 5 Refinery/petrochemical integration at HPCL-Mittal Energy Ltd., Bathinda, India

Integrated complex HMEL started with a base refinery of 9.0 MMTPA with 5% of chemicals production as polypropylene on crude oil pro - cessing. The refinery was expanded to 11.3 MMTPA (see Figure 4 ) and integrated with a new petrochemical complex to increase chemicals to 20% by adding more polypropylene and new linear low density polyethylene (LLDPE), high den - sity polyethylene (HDPE), and benzene units (see Figure 5 ) to maximise value by meeting domestic consumption needs. For the integration shown in Figure 5, an LP model was developed and validated for the new base case of 11.3 MMTPA with BS-VI fuels production. The product slate from this model served as the basis for economic analysis. Capacities of existing process units were utilised. Various configuration options for petrochemical integration were studied before arriving at the final configuration, including a dual feed cracker unit (1,200 KTPA) and downstream units: LLDPE/HDPE swing units (2 x 400 KTPA), HDPE unit (450 KPTA), polypropylene unit (500 KTPA), butene-1 unit (55 KTPA), and matching utilities and off-sites. The integration increased chemicals production and maximised value and profitability by meeting domestic consumption needs.

HMEL plans to increase chemicals to 25% by primarily increasing polypropylene and various percentages of poly - ethylene and benzene. This includes diesel cracking as one of the preferred options over and above refinery fuel gas, naphtha, LPG, and kerosene as feed to cracker in an inte - grated complex.
