Original title: Baling Petrochemical develops efficient phosphorus-free circulating water stabilizers to promote green production. The Fine Chemicals Plant of Sinopec Baling Petrochemical Longxing Industry Company has successfully developed efficient phosphorus-free scale and corrosion inhibitors (water treatment agents) that are environmentally friendly, help reduce energy consumption and emissions, and demonstrate good performance when used both within the company and in other applications. To date, the factory has produced nearly 500 tons of high-efficiency phosphorus-free scale and corrosion inhibitors, with a 100% production and sales rate. Recently, Bailin Petrochemical Longxing Company received an \"Evaluation Report on the Effectiveness of Low-phosphorus and Phosphorus-free Scale and Corrosion Inhibitors\" issued by the Production Technology Department of Hubei Fertilizer Branch. The report indicates that the three circulating water systems at Hubei Fertilizer used the low-phosphorus and phosphorus-free scale and corrosion inhibitors produced by Longxing Fine Chemicals Factory from May to July this year; the systems operated smoothly without any abnormalities. In particular, during the use of these high-effective phosphorus-free scale and corrosion inhibitors, the measured concentrations remained very stable, which provided effective guidance for the dosing process. All the monitoring data met the technical requirements for water management set by Sinopec, indicating that the inhibitors were effective in their function. ” A high-efficiency phosphorus-free scale and corrosion inhibitor is a highly effective and non-toxic water stabilizer for circulating water, capable of meeting the requirements of various water quality conditions in such systems. It can replace the commonly used phosphorus-containing scale and corrosion inhibitors, and represents a green and environmentally friendly product that should be widely promoted. In accordance with the new environmental protection standards, Sinopec requires its subsidiaries to ensure that the total phosphorus content in the wastewater discharged by them is less than 1.5 milligrams per liter, starting from July 1, 2017. To strengthen source control and promote compliant emissions, Baling Petrochemical has required Longxing Company to develop, and test in some circulating water stations, high-efficiency phosphorus-free scale and corrosion inhibitors. Since last year, Longxing Company of Baling Petrochemical has organized the technical team from its fine chemicals factory to work on the development of efficient phosphorus-free scale and corrosion inhibitors. Based on more than five months of dynamic simulation tests conducted at Baling Petrochemical’s water quality laboratory, these inhibitors were tested in five circulating water systems belonging to the coal chemical division, caprolactam division, and thermal power division in Yueyang city for over two months, with satisfactory results. The series of high-efficiency phosphorus-free scale and corrosion inhibitors developed by this factory can meet the treatment requirements of different water quality conditions, with an annual production capacity of 3,000 tons. In April this year, the circulating water system in Hubei Fertilizer’s utility engineering department changed the chemicals used; the ethylene glycol circulating water system began to use the high-efficiency, phosphorus-free scale and corrosion inhibitor produced by Lingxing Company of Baling Petrochemical ； Starting from May 1, low-phosphorus and phosphorus-free scale and corrosion inhibitors have also begun to be used gradually in the gasification circulating water and synthetic thermoelectric circulating water ； In June, all three circulating water systems at Hubei Fertilizer used phosphate-free chemical formulations. Based on the current monitoring results of the corrosion rate and adhesion rate in the circulating water system, the expected outcomes have been achieved, meeting the requirements for on-site use. In addition, Guangxi Liuzhou Fertilizer Co., Ltd. purchased 12 tons of this high-efficiency phosphorus-free scale and corrosion inhibitor at one time for trial use, and reported good results. It is reported that the high-efficiency phosphorus-free scale and corrosion inhibitor developed by the Fine Chemicals Plant of Baling Petrochemical Longxing Company utilizes a variety of high-performance scale-dispersing agents, thereby enhancing the agent’s ability to prevent scaling and disperse scale. Meanwhile, the use of new types of tracers makes the analysis process simple; this approach effectively solves problems such as the difficulty in detecting the concentration of phosphorus-free agents in circulating water and the tendency for analytical results to be inaccurate. It facilitates stable and effective control of the agent concentration in circulating water systems, thus promoting their smooth operation. In line with Baling Petrochemical’s plan to promote clean production and build a green enterprise, 9 of its circulating water systems will switch to using high-efficiency phosphorus-free scale and corrosion inhibitors next year.
