【Abstract】 In response to the scaling and environmental protection issues existing in the traditional phosphate process, a phosphorus-free polyamine film-forming agent was developed for use in the waste heat boiler of the catalytic cracking unit.By means of the film-forming mechanism and in coordination with the functions of the dispersant and the alkalized amine, efficient protection of the water vapor system is achieved.Industrial tests have shown that this technology not only optimizes the boiler water treatment process but also ensures the safe and stable operation of the system, reduces the boiler blowdown rate, and improves the quality of boiler water and steam.After calculation, 39 153 t of desalinated water can be saved annually, equivalent to 1 712 t of standard coal, achieving a net benefit of 1.519 5 million yuan per year.This achievement has verified the engineering applicability of this technology, which is free of phosphating and has low pollutant emissions, providing an efficient and environmentally friendly water treatment solution for refining and chemical plants.更多还原
