How to set up the venting for crystalline materials
Thread Content
Our company currently has a material with a melting point of 40 degrees Celsius. After purification through distillation, it is transferred to the finished product tank, where its temperature remains at 60–70 degrees Celsius. A nitrogen seal at a pressure of 0.8 KPa is used, but this often results in the one-way valve being clogged by crystallized material; the receiving tank at the top of the distillation tower also faces this problem. The solution we have in mind now is to add heat tracing and direct it to a tank of alkaline solution for absorption treatment. Experts, do you have any good suggestions: no clogging, and odor-free exhaust.
Heat (at a temperature of 50–70°C) and insulate the areas that need to be sealed, such as breather valves.
The spray granulation method is used: the hot-melted product is ejected from a nozzle, cooled by air to solidify, and the granulation tower is sealed
The heat tracing option still has a lower cost, and the temperature isn’t very high
