Should methanol wastewater with a concentration of around 30%–50% be classified according to fire hazard categories? ? ?
The flash points of 30% and -50% methanol aqueous solutions are 35°C and 24°C respectively, and their fire hazard can be preliminarily determined based on these flash points.
May I ask if this flash point is accurate? How is it calculated
The \"Safety Operating Guidelines for Methanol\" (Chinese version) provided by the renowned methanol producer Methanex contains a curve showing the relationship between the concentration of methanol in aqueous solution and its flash point, which should be quite reliable. It is also possible to entrust a domestic entity with the appropriate qualifications to conduct the testing, but fees will need to be paid.
