Abstract The traditional chlorine-containing coal transportation antifreeze has a relatively high chlorine content, which can easily cause corrosion and corrosion of coal-fired equipment, transportation equipment, and spraying equipment. At the same time, the acidic gas formed after combustion is easy to cause environmental pollution. Compared with chlorine-containing coal antifreeze, chlorine-free coal antifreeze has better antifreeze performance, anti-corrosion performance and stability. However, due to its high cost, its promotion and use are hindered. In order to develop an anti-freezing liquid product with excellent performance and low comprehensive cost, the experimental group screened a variety of pour point depressants to compound the pour point depressant compound, selected a variety of corrosion inhibitors to compound the corrosion inhibitor compound, and added thickening stabilizers. The solid low-chlorine coal transportation anti-freezing liquid product was prepared through a large number of tests. According to the test method specified in the industry standard TB / T 3208-2008 " Technical Conditions for Anti-freezing Liquid for Transportation of Bulk Granular Goods, " all performance indicators met the requirements. In order to test the field use effect of low-chlorine products, the solid coal transportation antifreeze and water are processed into antifreeze products by a certain proportion, and industrial tests are carried out on the trains of three loading stations in Anjialing Open-pit Mine, Antaibao Open-pit Mine and East Open-pit Mine of Pingshuo Group.The test period was 3 months. The results showed that the anti-freezing performance and corrosion inhibition performance of the new low-chlorine coal transportation antifreeze product were better than those of the traditional chlorine-containing coal transportation antifreeze.
