Method of feeding externally purchased trichlorosilane into the system
Thread Content
May I ask: What is the method used by various factories to feed trichlorosilane into the system?
Is it the method of adding materials? First, it’s pumped into the tank area, and then it enters the distillation tower for distillation
It is carried out using a loading/unloading dip pipe, and the nitrogen filling pressure must be controlled during material compression.
Are you referring to purchasing trichlorosilane and then introducing it into your factory’s production system? 1# refers to that cricket 28
First, use the pressure from the transport tank to push the purchased trichlorosilane into your factory’s storage tanks; afterwards, increase the pressure in those tanks or use pumps to feed the product into the production system
Is nitrogen pressure used for feeding in all cases? What should the nitrogen pressure be, and what should the time limit be?
It is pressurized with nitrogen; generally, a pressure difference of 1 to 2 kilograms is sufficient for tank trucks and storage tanks. Of course, increasing the pressure speeds up the filling process, but safety considerations prevent using too high a pressure
Is there any that uses a pump? Some say yes, but what model of pump is used?
Feeding with a pump is not entirely impossible, but there are two factors that generally lead to the decision against using this method: 1. Cost – For a truckload of 30 tons of trichlorosilane, it usually takes about an hour to unload it. What is the price of a pump with such high capacity? 2. Safety – Given the properties of the material, safety considerations dictate that discharge is generally done through pipes inserted deep into the container; this makes it easy to push the material forward without the need for a pump
Nitrogen is fed into the tank at a pressure of 2–2.5 kilograms. Pump into the tower; nitrogen pressure can also be used to push it in at the old plant site
