In 2019, Petromidia Refinery recorded an energy consumption 2.99 GJ/mt related to the ton of throughput, situated at the same level the one recorded in the previous year. The utilities cost increased by 3.6% (USD ~0,34/ton), up to USD 9.6/ ton, as compared to the previous year, correlated with an increase in the prices of utilities. Total energy input for Petromidia Refinery in 2019 reached 475,871 MWh, a relevant decrease in the context of its processing capacity considerable increase, generated by the improvement of its energetic efficiency as well as its operational focus on enhancing energetic performance.
As for Vega Refinery, the energy consumption reported to throughput ton suffered a decrease by approximately 2% in 2019, operational result stemming from the different functioning of the plants, as well as the measures taken to reduce consumption. Fuel gas consumption reported by the ton (GJ/to) decreased by 0.2%, while the power and steam consumption reported by the ton (GJ/to) also decreased, by 1.4%. With a total energy input of 10,940.004 MW in 2019, Vega’s energy consumption reported by the ton registered an increase by 6% as compared to the previous year.
Due to the low flow rate of the LDPE installation and the conservation of the HDPE unit throughout the entire year, the Petrochemical Division only saw improvements only in its power consumption, from 5.3 to 4.9 GJ/to in 2019. Since utilities consumed during non-operation increase the EIP, the Petrochemical Division reached an energy index of 18.7, slightly higher than the 18.18 of 2018.
