Technological transformation is an effective shortcut for enterprises to increase production efficiency. In recent years, Daqing Refinery Polymer Plant No.2 has spared no effort to carry out technological reform and efficiency exploration. In 2007, the operating efficiency of polyacrylamide plant at this plant climbed to 135% of the design load, and the peak output of 27,000 tons was kept stable.
At the beginning of this year, the plant took the opportunity of the “Fine Management and Solid Foundation Year†activity to look at the equipment load from the perspective of the installation and found that the supply chain at the upstream of the installation was slightly strained. Solving the contradiction between supply and demand of materials means that we can overcome the bottleneck of production. To this end, the plant scientific research personnel according to the principle of material balance, the upstream process of the device will be analyzed section by section, will restrict the production of key points in the hydrolysis section of the first granulator machine hole diameter from the original 2.0mm to 2.5mm, reducing The internal pressure of the granulator ensures smooth discharge and increases the material supply capacity. At the same time, they also scientifically adjusted the opening of the steam valve of the secondary granulation motorized stator blade gap and the dryer, ensuring the dry quality and grinding effect of polyacrylamide particles.
Statistics for July show that after the completion of the technological transformation, the two polyacrylamide technical upgrading devices of the plant increased by an average of 3 tons per day. The single-day production capacity increased by more than 8.33%, and the comprehensive energy consumption was reduced by 10% compared with that before the technical reform. .
Daqing refining and polyacrylamide plant technology reform and efficiency increase
On August 11th, Daqing Refinery Polymer Plant No. 2 again took advantage of technical reforms to increase effectiveness. The polyacrylamide unit of the plant was successfully established in the first stage of the pelletizer, and the single production line after the technical transformation can increase production value by more than 2 million yuan annually.
