Huaxing Petrochemical continued to improve its energy management system this year, conducting “lean” management through energy conservation and consumption reduction. Its comprehensive energy consumption dropped 8.64 units year-on-year to 71.47 kilograms of standard oil per ton of product from Jan to July. The processing load has also significantly increased.
The company gathered technical and production departments to analyze the overall situation of energy use across the plant to create an energy plan for 2013. It also modified energy-use evaluations based on 11 sustainable improvement projects, breaking them down for various departments to act on. The evaluation took into account unit consumptions of water, electricity, gas and nitrogen. It also kept track of energy consumption of major equipment. The company carried out special checks and had departments do self-checks, making analyses every two weeks to find and solve problems. It also set up energy conservation and emissions reduction awards as well as differentiated performance evaluations. One of its energy-use renovation projects can effectively reduce steam consumption in raw oil pretreatment and catalytic and coking units, yielding an annual profit of 5.96 million yuan ($973,229).
The company also took the energy conservation week in June as an opportunity to have more than 820 people attend an energy conservation training and watch a special exhibition to promote green, low-carbon production concepts. It exposed and corrected wasteful practices, which also helped raise awareness of energy conservation and consumption reduction.
Huaxing Petrochemical also focused on catalytic, adjuncts and additives management. It formulated plans for quarterly demand and applied a quota system for their usage. It also set up standing books in various links, such as purchase, use and stocks to avoid random application and use of the three reagents. The efforts have brought down consumption, saving 12.36 million yuan in processing costs.
