As of April 8, after three months of monitoring data showed that the hardness and dissolved oxygen of the high pressure polyethylene hot water system of Daqing Petrochemical Company was significantly lower than the index value, the qualified rate of pH was stable at 100%, and the water quality was excellent.
Daqing Petrochemical Co., Ltd. In order to solve the corrosion problem of hot water systems in high-pressure polyethylene installations, the company's research group focused on preventing the corrosion by controlling the pH of the dosing system. The second is the use of a new type of oxygen scavenging and film forming chemicals instead of the currently used hydrazine oxygen scavenger to improve the oxygen removal of the feed water and ensure the water quality of the hot water system is good. The third is to treat calcium ions and add dispersants. After nearly three years of technical breakthroughs, the research team completed the reform of the hot water system dosing equipment, the trial of new drugs, the selection of dosing points, and the transformation of samplers. During the major overhaul of equipment in August 2010, it was completed and put into use. Device production.
