The new high-efficiency DTS coalescing filler solves the problem of high oil content in lignite coke wastewater

Thread Content

Introduction to wastewater generated in lignite carbon production: Lignite carbon production is a medium- and low-temperature (around 650°C) dry distillation process that uses non-sticky (or weakly sticky) coal as raw material. During this process, products such as lignite carbon (semi-coke), light and heavy coal tar, as well as medium- and low-temperature dry distillation gas are obtained. Compared with the high-temperature (around 1000°C) dry distillation process used for coke production, the gas produced by the medium- and low-temperature dry distillation of lignite carbon does not undergo secondary cracking at high temperatures; moreover, the washing water used to treat this raw gas contains a large amount of pollutants that have not been oxidized at high temperatures. The wastewater generated during the low-temperature carbonization of raw coal and the purification of gas in the production of semi-coke is known as semi-coke production wastewater. This wastewater has a complex composition, containing large amounts of cyclic organic compounds and azide-based inorganic compounds, as well as high levels of oil, ammonium cyanide, phenols, COD, and SS in the water. Our company has recently developed a new DTS packing technology specifically designed for the treatment of oily wastewater (a utility model patent has been filed for it). The key features of this technology are as follows:  High efficiency (30% to 60% more efficient than traditional coalescing plate packings) ； The oil phase removal efficiency for any oily wastewater can exceed 90% ； The same effect is also observed on other impurities that are soluble in the oil phase ；  Can effectively reduce the size of separation equipment ；  Unique coarse-graining coalescence technology that eliminates the need for emulsifying the oil phase ；  Highly suitable for water separators in heavy oil and thick crude oils ；  Highly adaptable to fluids with high levels of sludge flocs and solid suspended particles ；  Easy to install for new and renovated separation equipment ；  Cross-flow process ；  Can reduce the impact of surface waves and liquid surface oscillations ；  The plate gap can be adjusted according to the requirements and characteristics of fluid processing ；  Horizontal or vertical installation ； Beneficial for overall modularization ； Wide range of applications ； Wide range of application fields ；  Metal and non-metal materials can be selected ；  No moving parts, easy to clean and maintain; pure physical removal process with no energy consumption (except for the inlet and outlet pumps) ； Scope of application and fields of use:  Treatment of semi-coke wastewater  Systems for treating crude oil and condensate in offshore and onshore oil and gas fields  Water treatment systems for fluids produced in offshore and onshore oil and gas fields  Treatment of domestic wastewater  Ships  Chemical industry  Oil refining  Power plants  Airports  Railways. Our company has conducted field experiments on the oil removal efficiency of this solution for semi-coke wastewater (with results provided by third-party testing agencies), as well as practical applications in real projects: a company in Yulin City. The experiments and practical applications have shown that this product offers extremely high efficiency in removing oil from semi-coke wastewater; no emulsification is required, and the oil obtained can generate economic benefits.
