ONE-HEART Tar Demulsifier 71700plus is a water-soluble demulsifying and viscosity-reducing agent that enhances the speed and efficiency of separating tar from ammonia water. Through its demulsifying, dispersing, and viscosity-reducing actions, it thins the emulsion layer of tar in ammonia water, thereby improving the separation efficiency of tar from ammonia water within the separator. This leads to a reduction in the amount of suspended particles present in the ammonia water, as well as a slight decrease in the surface tension of the tar. It accelerates the separation of tar from tar residues, resulting in tar with lower levels of moisture and residues. At the same time, it minimizes the amount of suspended particles and oil that end up in the ammonia water, improving the quality of the recycled ammonia water and enhancing the effectiveness of treating residual ammonia water. Create the following value · The moisture content in tar will decrease, and quinoline-insoluble substances will also be reduced accordingly ； Tar moisture content decreases by up to 60% · Tar viscosity is reduced ； 40% reduction · Lower oil and suspended solids content in ammonia, resulting in a cleaner quality. · The ammonia stripper and heat exchanger significantly reduce the frequency of cleaning the heat exchanger and oil discharge from the ammonia stripper ； ＊ It can reduce the costs of cleaning heat exchangers and ammonia strippers. ＊ The oil drainage frequency at the bottom of the tower is reduced by 90%, and the discharged liquid is mainly ammonia water with very little tar content. · Primary cooler * Achieves a better spraying effect and optimal primary cooling resistance ； ＊ Lowers the temperature at the gas outlet of the primary cooler, thereby effectively reducing its thermal load ； · Tar recovery rate * The tar recovery rate is increased by more than 0.54%. · Chemical products: Helps improve the color of products such as ammonium sulfate and sulfur paste. Coking wastewater treatment: It can reduce the level of toxic COD as well as the total COD content in the wastewater. Thereby reducing the microbial treatment load and maintaining a higher number of viable microorganisms as well as enhanced microbial vitality. Tar-ammonia separation technology: Ammonia and tar produced by the spray condensation of coke oven gas are the two main by-products in the coking process. If recirculated ammonia water is not properly treated, it will not only affect the smooth operation of production and the production process, but also lead to pressures related to environmental emissions. Currently, there are several chemical methods available internationally to improve the quality of tar. When these chemical approaches are combined with improvements in the operation of on-site equipment, good results can be achieved. 1. Oil-based solutions: This technique involves adding tar viscosity reducers and demulsifiers to the gas collection pipes and bridge pipe spray circuits. By using this method, it is possible to increase the dehydration rate of tar, as well as to have a positive effect on the quality of the circulating ammonia water. Wanhe tar dehydrant is also an excellent anti-adhesion agent; it forms a layer on the surface of the tar, thereby reducing its adhesiveness. II. Problems that can be solved and value returns • The moisture content in tar will decrease, and the quinoline insolubles will also be relatively reduced ； Tar moisture decreases by 60% • Tar viscosity decreases ； 40% reduction in decline • The oil and suspended solids content in ammonia water is reduced, resulting in a cleaner quality. •Ammonia evaporation tower and heat exchangers * Significantly reduces the frequency of cleaning the heat exchangers as well as the frequency of oil drainage from the ammonia evaporation tower ； ＊ It can reduce the costs of cleaning heat exchangers and ammonia strippers. ＊ The oil drainage frequency at the bottom of the tower is reduced by 90%, and the discharged liquid is mainly ammonia water with very little tar content. •Primary cooler * Achieves a better spraying effect and optimal primary cooling resistance ； ＊ Lowers the temperature at the gas outlet of the primary cooler, thereby effectively reducing its thermal load ； ＊ The cleaning frequency is increased, reducing cleaning costs. The quality of the condensate has improved; the deposition of tar, naphthalene, suspended solids, etc. in the primary cooler has decreased, and some of the already-deposited substances are being washed away. As a result, the resistance in the primary cooler has been reduced by more than 50% ； Reduce energy consumption and cut maintenance frequency and costs by over 40%. •Coke oven nozzles and gas collection main pipes * **Reduce clogging of ammonia water nozzles, maintain the amount of ammonia water spray, and stabilize the cooling temperature of raw coal gas** ； ＊ Reduce the workload for cleaning the spray system and the gas collection main. Nozzle clogging is reduced by over 90%, and clogged nozzles are easier to clean. •Pressure flap * Greater flexibility, improved control of coke oven pressure, and reduced gas leakage. •Tar-ammonia separation tank * The amount of tar residue produced is reduced, while the tar production increases accordingly, thereby cutting the costs associated with handling tar residue. Reduce the tar content in tar residues by more than 50%. •The corresponding reduction in energy consumption * A decrease in the moisture content of tar reduces the amount of steam needed to maintain the temperature of the tar storage tank ； ＊ A reduction in the moisture content of tar will lower the energy consumption of dewatering equipment such as super centrifuges ； ＊ A proper outlet temperature of the primary cooler enables obtaining coke oven gas at a lower temperature; this reduces the volume of the gas, thereby decreasing the energy consumption during its transportation. •Tar recovery rate * The tar recovery rate increases by more than 0.54%. • Chemical products: * It helps to improve the color of products such as ammonium sulfate and sulfur paste. •Treatment of coking wastewater: * The pollutants in coking wastewater mainly originate from tar contamination. The difficulty in treating coking wastewater is mainly due to the toxic CODcr generated by tar. Therefore, controlling the content of tar in wastewater is the key to solving the treatment of coking wastewater. Classification and degradation analysis of CODcr in coking wastewater: It can reduce the level of toxic COD as well as the total COD content in the wastewater. Thereby reducing the microbial treatment load and maintaining a higher number of viable microorganisms as well as enhanced microbial vitality.
