Software helps CNPC Jilin Petrochemical to cut energy costs
4 Apr 2011
Singapore - China National Petroleum Corp. (CNPC) Jilin Petrochemical Co., northeast China’s largest integrated refining and petrochemical production facility is employing process optimisation software to better respond in real time to changes in feedstock variation, process conditions and utilities prices to achieve sustainable energy savings.
Invensys’ SimSci-Esscor ROMeo software including off-line operational analysis and on-line plant modeling for ethylene production, also allowed CNPC to study and validate the feasibility of various energy-saving strategies and the key parameters impacting energy saving before implementation.
The technology was applied to the entire ethylene complex, including 10 cracking furnaces, quenching, compression, cracking and separation equipment across CNPC’s 700,000 tons-per-year ethylene production unit. The solution helped drive sustained reductions in the refinery’s energy consumption by5%.
“CNPC is devoted to reducing our worldwide carbon emissions, and one of the best approaches is to invest in technology that can maximise our energy efficiency,” said Liu Hongji, deputy factory director, CNPC Jilin Petrochemical Co.
“After careful market research and assessment, we chose [the Invensys software] to help us save energy, improve visibility into our operations and, ultimately, drive productivity.
“The results prove that the implementation … has reduced the energy consumption of our ethylene production unit and improved the effectiveness of the plant on the whole.”
