What type of reactor should be used for substances that react violently with water?
Thread Content
Our company produces hazardous chemicals such as boron trichloride, phosphorus trichloride, and boron tribromide. Such products all share one characteristic: they react violently when exposed to water! There is one issue when choosing a jacketed reactor. How to prevent the jacket water from entering the reactor and reacting with the product under extreme conditions? Or are there any more advanced technical products or skills that can enable heating and cooling while preventing water from entering the reactor?
The problem you mentioned can be solved by not using water for heating and cooling
To heat something, heat transfer is necessary; if protection is required, an additional layer of steel plate or similar may be needed, which could reduce the efficiency of heat transfer. Is it possible to achieve indirect heating by using a suitable heat transfer medium that does not react with the material being heated, and to use steam or hot water to heat this medium as a means of delivering heat. My personal understanding, for reference only.
So what is used to heat or cool the reactor?
If the equipment is properly made, how could water leak through? First, we manufacture the main body of the equipment, and then weld a jacket around it. Our factory has been using steel plate containers for over a decade, and we have never seen any leakage in their wall panels
These products are all acidic and must absolutely avoid water. I’m worried that over time the main body might get corroded and punctured.
To avoid corrosion, choose the right material: for ordinary low-concentration acids, 304, 316, and 316L are suitable; for more aggressive acids, 2205 stainless steel is used, and for even more extreme conditions, titanium or zirconium materials are employed； If the pressure is not high, copper or aluminum materials can also be used; if the temperature is not high, organic materials can also be used

Can heating be achieved using things like heat transfer oil or organic solvents?
The key factor is the heating temperature; moreover, using instruments for interlocking should improve safety performance
Use half-pipe heating to avoid the tank body welds
