Measures and potentials of energy-saving in a Chinese fine chemical industrial park

This study aims to fill the gap in the literature on energy efficiency and economic analysis of energy-saving measures at the industrial park level by conducting a case study of a typical fine chemical industrial park in China. Based on a five-year intensive data collection, the authors quantitatively examined the energy consumption and energy efficiency of the industrial park in question and evaluated the energy-saving potentials and cost-effectiveness of ten types of energy-saving measures by means of a bottom-up method and scenario analysis. It was found that the energy efficiencies of its two combined heat and power plants in 2007 were 81.5% and 56% respectively. Energy efficiency of the fine chemical industrial park was around 4625.7 GJ per million USD of gross industrial output value, which was only between 20% and 25% of that of the sector of manufacturing raw chemical materials and chemical products in China. The energy-saving potentials of the ten measures amount to about 11% of energy consumption of the industrial park in 2007. A total capital investment of approximately 35 million USD would be needed to realise the potentials. The technical measures explored in the study are generally replicable in other Chinese fine chemical industrial parks.

► We studied energy-saving potentials & cost on a fine chemical industrial park scale.
► Energy efficiency is 4625.7 GJ/million USD and 97 GJ per tonne-total-organic-carbon-output.
► Bottom-up method & scenario analysis are used to value ten measures' cost-effect.
► Ten measures have 11% energy-saving potential based on energy consumption in 2007.
► Total invest about 35 million USD is needed to realize the potential.
