Zhenghe Petrochemical has actively implemented the strategy of energy saving and emission reduction through technological innovation and benefited a lot from the strategy. Since last August to June this year, the company has screened and approved 63 projects, of which, 36 projects have been completed, saving the equivalent of 2,000 tons of standard coal in management and 15,000 tons in projects.
The company was led by science and technology and started from basic energy saving and emission reduction tactics such as electricity and water saving. It constantly made use of new technologies, improved manufacturing processes, renovated equipment and optimized the energy consumption of manufacturing control devices. In order to control the increased generated sewage water from the new device, the technological team tested and analyzed the sewage water generated by various production devices, and separated the clean water from sewage water. And, its total sewage water disposal volume dropped by 30 percent.
During production, the optimization of thermal efficiency for heating furnace equipment is a key control point. The online monitoring system, ancillary components and control system of Zhenghe Petrochemical are not ideal for optimized operation of the heating furnace; therefore, a big gap still remains to be filled, considering the current advanced level in the industry. In responding to this, the company set up a special technological team and carried out pilot transformation for the coking furnace of the hydrogenation coking unit and conversion furnace. Through the application of new technologies and process transformation, the thermal efficiency of the hydrogenation coking unit’s coking furnace and the conversion furnace rose from 79 percent to 85 percent and from 81 percent to 88 percent respectively after operation, saving the equivalent of 2,000 tons of standard coal. Similarly, in order to carry out energy optimization for the decompression device, the company adopted the latest technologies, optimized the operation and partially transformed the decompression device by taking into account the raw oil nature and the running situation. As a result, they produce qualified products, and increase annual profits by more than 5 million yuan.
On the basis of vigorous implementation of scientific energy saving, Zhenghe Petrochemical has set up corresponding energy saving reward funds, formulated detailed and strict system of reward and penalty in terms of energy saving. It also carried out performance appraisals on energy saving projects to reward departments and individuals that make outstanding contributions to energy saving and emissions reduction. At present, the company has made more than 60 acknowledgements.
