Protection of heat transfer oil in winter
Thread Content
8 m3 of heat transfer oil with a freezing point of -20°C is used for hydrogen production via methanol cracking. In winter, when the temperature drops to -30°C, all of this oil is transferred into a 12 m3 oil storage tank that is insulated; however, the pipe leading from the bottom of the tank to the outlet valve is not insulated and is 20 cm long. Under such conditions in Xinjiang’s winters, when the equipment is not in use, is it possible to fill the oil storage tank with oil? What dangers could arise if oil is poured in?
If driving in winter, steam or electric heating can be added externally.
It’s so troublesome. In such an environment, oil storage tanks and pipelines are equipped with insulation and heating systems. The viscosity of the heat transfer oil is very high; it may even solidify, making it impossible to inject oil, and this will cause the pump to fail.
I won’t be driving this winter; filling up the tank now makes it easier to install the catalyst.
Oil can now be added. The main concern is that if oil is added and temperatures drop below -20°C in winter, the pipe openings at the bottom of the oil storage tank might crack, damaging the pipelines and equipment and causing oil leaks. I would also like to ask: if the oil solidifies and its viscosity increases, will the quality of the oil be significantly affected by the time spring arrives?
