With respect to the new pattern formed through the integration of refining & chemical after the completion of the ethylene project, ZRCC optimized the whole production units to facilitate the energy conservation. From Jan. to Aug. of this year, the comprehensive energy consumption of refining achieved 68.51kg standard oil per ton of product, a drop of 11.27% from the same period of the previous year.

As the largest refining & chemical company of China, ZRCC has made great efforts to arrange the production schedule this year, such as stop urea production since April to create conditions for its refinery to keep the Hydrogen Unit out of service; furthermore, the make-up hydrogen compressor in Diesel Hydrotreating Unit is basically out of service due to using the pressure energy of hydrogen from Fertilizer, which is estimated to reduce the energy consumption by 249,000 tons standard coal this year. After start-up of the ethylene plant, ZRCC comprehensively propels the optimization among each unit so as to successively shut down a number of compressors to lower the energy consumption.

　　

Power consumption is one of the major energy consumption for refining & chemical company, and the power consumption in refining section accounts for more than 20% of its total energy consumption. For the purpose of reducing power consumption, ZRCC established a dedicated power conservation technical innovation group and took some measures, i.e. newly installing or relocating the frequency converters, improving the heat integration of unit streams, etc. As a result, from Jan. to Aug. of this year, the power consumption per ton crude oil processed in refining section of ZRCC achieved 40.95 KWh, which decreased by 7.05 KWh compared to the same period in 2008 with a decrement of 16.7%. In this year, the power consumption reduction has accumulated to 101.28 million KWh, and the production cost has decreased by 58.74 million Yuan, which enable ZRCC to take the leading position in Sinopec as far as the power consumption per ton crude oil processed in refining section is concerned.

Steam consumption per ton oil of ZRCC increases with years as the production scale expands. It is difficult to balance production and demand of steam. Focusing on steam saving, the company reduces steam consumption per ton oil from two years ago, 121.7kg/ton, to at present, 85.7kg/ton, a decrease of 29.6%, actual amount of total steam consumption decreases by 399,000 tons while crude oil throughout increases by 6.0%, with direct economic benefit of RMB 43,900,000.

In order to promote energy conservation and consumption reduction, ZRCC compares indicators of every discipline with international and domestic advanced level, works hard to improve control level of energy conservation and consumption reduction. The company organizes several rounds of technology tackling for energy conservation, cost-reduction and profit increase. Diagnoses energy usage in the operating departments, and takes measures. From January to August of this year, the company saves energy over 0.99 kg standard oil per ton through optimization management.

ZRCC also further strengthens evaluation of energy-saving and monthly breaks down energy saving indicators, carries out energy-saving competitions and energy-saving reward activity. At present, the company takes 60 measures of energy conservation and consumption reduction, which can save 21,200 tons standard oil when put into effect.
