| Cryogenic effect For this reactor the low temperature is applied by two parts. The jacket and the inner cooling coils. Both of them could be injected with the refrigerants to reduce the temperature within the kettle. To achieve the temperature as low as negative 40°C，the cryogenic process is seperated into two steps. ᆞ First, the refrigerant at -15°C will be input to the jacket, and reduce the kettle temperature under -10°C. ᆞ Secondly, stop and refrigerant inputing to jacket, and start the liquid nitrogen inputing to the inner coils. The liquid nitrogen is -60°C, so it will keep reducing the temperature until -40°C. |

Meterial for kettle:
The reactant medium are including the H2SO4 solution, aqueous hydrobromic acid solution, and HCL solution. So, the tatinium alloy is chosen as the medium contacting material for the reactor. Because the volume required is as large as 1000 liters, using pure titanium alloy would cost too much. So, we applied the clad sheet composited with titanium and stainless steel. The titanium alloy is only for corrosion resistant, while the stainless steel S304 is used to offer supporting strength.
The titanium to be used in other parts:
ᆞ Beside the kettle body, the stirring parts including the axis, coupler, blades are made from titanium.
ᆞ The inner coils immersed inside the medium is made from titanium pipe.
ᆞ The flange is made from titanium lined stainless steel.
ᆞ The parts of mechanical sealing shaft sleeve coupler that to contact with medium is using titanium alloy too.

ᆞ Mechanical seal， PTFE seal, collector, explosion-proof motor, reducer, frequency converter. ᆞ The inner and outer surfaces of the kettle are polished to Ra≤0.4μm. ᆞ Sight glass and explosion-proof sight glass lamp, blind plate for discharge port, pressure gauge, and valve for vacuum jacket ᆞ Automation controller. It is specially programmed to achieve the cryogenic process by controlling the vavles and timing of the refrigerant inputting and remaining time. Profile: The kettle is with a bigger belly than other batch reactors. It is because our customer requires 1000L volume but a short height of the reactor. Although the bigger diameter of the cylinder causes high pressure withstand feature of the reactor, the basic thickness requirement of base plate S304 at 12 mm is enough to meet the needs. |
