Methylal Refining Technology
Proprietary Technology and Plants
Methaldehyde has excellent physical and chemical properties, that is good solubility, low boiling point, and water compatibility can be widely used in cosmetics, pharmaceuticals, household goods, automotive supplies, pesticides, leather polish, cleaning agents, rubber Industrial, paint, paint, ink and other products, but also because the methyl acetal has a good ability to oil and volatile, as a cleaning agent can replace F11 and F113 and chlorine solvent, it is an alternative to freon, reduce volatile organic compounds (VOCs ) Emissions of environmentally friendly production.
As the methyl acetal and water, methanol to form azeotrope, the traditional distillation method can only get about 92% of the methylaldehyde ternary azeotrope. However, in the methylal industry, in addition to part of the solvent uses 85% -93% purity, the rest need more than 99% purity of the methyl acetal products. At present, the industrial formaldehyde refining methods are mainly salt distillation, liquid-liquid extraction, ion exchange, adsorption and pressure distillation method.
Hubei Sanli Fengxiang Technology Co., Ltd. (SL Tech) is a young technology company specialized in providing EPC contracting service and the import & export of chemical plants? with the headquarter located in China(Hubei) Pilot Free Trade Zone and an office in Wuxi. Also it is the shareholder of Wanian Jinze Electronic Material Co., Ltd. with 20,000TPA methyl acetate production capacity, and Henan Bojie Energy Engineering Technology Co., Ltd. Dedicated to the diesel’s desulphurization by non-hydrogenation process. SL Tech has stuck to the path of the combination of production and research. Thanks to the R&D strength of its partners including famous universities and institutes as well as its own highly experienced highly qualified team, it has proprietary intellectual rights of production technologies covering chemicals like alkyl-phenol and derivatives, acetates( including methyl acetate, ethyl acetate and iso-butyl acetate), MTBE, MIBK, dihyoxybenzene, trioxane, dioxolane, iso-butyl acetate, iso-butene and etc., and is capable to provide package engineering services and solutions from PDP (Process Design Package), design, procurement, erection, to commissioning, startup and technical training. We are very proud to say we are one of the best teams expertized in chemical distillation-purification technology in China, from computer aided simulation, lab verification and modification, pilot plant to commercialized plant. Meanwhile, with the increasingly developing of China’s chemical technology ( some even reaching the leading level in the world), and depending upon its team’s years experiences of chemical plants foreign trade, SL Tech is also dedicated to provide China’s advanced coal chemical, petro chemical and natural gas chemical technologies to foreign customers incl. hydrogen peroxide technology, MMA technology, syngas to MEG technology, PO technology, PPC technology, UHMWPE technology, electronic grade solvent technology and etc.. view more »
