The Daqing Zhonglan Petrochemical Co has achieved its energy-saving goals for the 12th Five-year Energy-conservation plan. By the end of December, its energy consumption per 10,000 yuan of output value was 0.5 tons of standard coal, down 1.76 percent from 2011, while energy consumption by petroleum processing units dropped 4.67 KgEO/t, from 2011’s level, and saved-energy for 2012 amounted to 8,071 tons of standard coal, beating the year’s saving goal of 8,000 tons of standard coal, on average, set by the Five-year Energy-conservation plan.
The company made many adjustments in steam consumption. As temperatures fell in winter, the steam heating system for all facilities was adjusted to control steam use, while guaranteeing operations. The company also cut unnecessary steam heating for some facilities, based on design and experience. And, it adjusted the amount of heat exchange used for the circulating water system and lowered the amount of fresh water added to the system to save water. It did some technological upgrades on devices and facilities to save electricity. The steam reduction helped cut the use of coal by the power plant and the fresh water reduction in the circulation system helped cut electricity use by the pumps.
