Since the start of construction, the No. 2 Petrochemical Plant has organized cadre and benzene dewaxing workshop cadres and employees to create a "soft" environment and technological advancement "hard" measures to reduce energy consumption and improve profitability. First of all, from the perspective of establishing employees' sense of responsibility and crisis, we will purposely announce to employees the completion of important economic and technical indicators of the device. We will also look at the gaps with the advanced indicators of similar devices to reduce the cost-saving concept and crisis awareness. Rooted in the hearts and minds of employees. At the same time, the workshop uses the team economic accounting software to compare the monthly energy consumption completion and product yield of each team with the indicators of advanced units, and formulate rectification measures based on actual conditions. Every month, the assessment of the performance of each team's indicators is conducted, and it is linked to the monthly comprehensive awards. The rewards are excellent and punished, prompting the employees to implement energy-saving and profit-initiating effects from each operation details.
On the basis of fully building a "soft" environment for energy conservation and consumption reduction, PetroChina No. 2 Plant also actively used the "hard" measures of technological progress to implement technological transformation and optimize operational projects. Since the beginning of this year, the device has optimized the temperature and proportion of the pre-dilution solvent of the crystallization system, the solvent of the first dilution, reduced the amount of hot material entering the casing crystallization machine, reduced the refrigeration load of the device, and optimized the vacuum degree of the closed vacuum system of the device, not only improving the hardness Wax yield, while reducing the amount of closed air circulation in the device, reducing the power consumption of the device; significantly reduce the fresh solvent cycle ratio of the device, prompting the recovery system to save a lot of heating steam; optimize the heat transfer process of steam condensate, the original The designed normal temperature solvent and wax liquid heat exchanger was transformed into a heat exchanger for condensing water and wax liquid. At the same time, the heat exchange sequence of pre-dilution, primary dilution solvent and wax liquid and condensate was adjusted, so that the heat recovery and utilization was more fully realized. .
As the ketone-benzene dewaxing unit is "soft" and "hard", it achieves good results. The second quarter energy consumption index of the device decreased by 8.39% year-on-year, creating the best level of equipment, ranking first among similar equipment of CNPC. The product yield of the equipment increased by 0.88 percentage points year-on-year, and the production of paraffin wax was 1136.4 tons, creating 13.63 million profits for enterprises. Yuan has achieved the goal of saving energy, reducing consumption, and increasing efficiency, and has achieved "win-win" for the economic and social benefits of the company.
The second oil ketone benzene dewaxing unit in Fushun Co., Ltd. optimized operation, efficiency, energy saving
The deoiling wax, agent consumption and energy consumption index ranks first among the same type of equipment in the China National Petroleum Corporation. In the second quarter, it produced 1136 tons of paraffin wax, and created the largest ketone-benzene dewaxing unit in China—the 600,000 tons/year of ketone benzene from Fushun Petroleum No. 2 Plant. The wax device has been dedicated to optimizing the operation of the device since it was successful in July 2006. It has also tapped the potential of energy saving and consumption reduction of the device and improved the ability to create profit. From January to June of this year, the main technical indicators of the device, such as deoiling wax, agent consumption, and energy consumption, all rank in the forefront of similar equipment of CNPC. The yield of hard wax was 30.38%, which was 1.38% higher than the design. The energy consumption was 53.5 kg EO/t, which was 17.5 units lower than the design value.
