To manually charge different gases at desired pressures upto 140 bar / 2000 psi or higherinto the reactor from gas cylinder. Nitrogen, Oxygen & Hydrogen can be charged throughsame regulator (with special adaptor). The regulator is made from SS316 & comes with inlet -outlet pressure gauges & flexible SS braided Teflon PTFE high pressure hose pipe (4m long) with non return valve.
Gas boosters are useful when the cylinder pressures are much lower than the autoclave ratedpressures. In such case the booster takes gas at lower pressure from cylinder & compresses thesame to deliver at higher pressures. They are generally pneumatically operated. Special gasbooster pumps are available for liquid CO used in supercritical fluid extraction system. The 2booster systems are supplied with air filter regulator, pressure relief valves, inlet-outlet pressuregauges, valves & flexible hose pipe.
MFM can be used to measure accurate mass flow rate of gas (in gm/hr or LPH) & totalized quantity of mass / volume (in gms/ltr) charged in the autoclave at any point. Mass flow controller (MFC) is used to charge the set flow rate of gas into the autoclave at high pressures up to 100 bar or it can be used in pressure control mode to indicate the gas flow & total gas uptake to maintain desired set pressure inside the autoclave (ideal for hydrogenation). The same MFM / MFC can be used for multiple gases by just entering the conversion factor for different gas densities provided the gases are inert to each other. The MFM/MFC comes with high pressure flexible hose, inlet filter with digital gas flow indicator cum totalizer & additional pressure PID controller with pressure sensor if the MFC is used in pressure control mode. User has to specify the maximum flow rate range, pressure, gas & mode (flow control or pressure control) for ordering MFM/MFC.
These are used for higher & accurate gas or liquid flow rate indication or control in cases where thermal mass flow meters are not suitable. A common meter can be used for different gases & liquids for a particular range of flow.
It consists of SS316 pressure sensor (transmitter) & digital pressure indicator/ controller (mounted on common control panel) with pressure alarm & optionally heater cut off for safety. Digital pressure indicator has pressure reading in bar & psi, where as controller reads any one ofthe units. The controller is normally used with mass flow controllers (MFCs) or solenoid/flow control valves to maintain constant pressure inside the autoclave. With MFC, gas flow indicator & totalizer are also provided on the same panel. The pressure sensor has temperature limitation upto 100°C & hence the same is provided with water cooling jacket.
This system is used to charge liquid at a desired rate from as low as 1 ml/hr to 100 ltr/hr, when the autoclave is under pressurized condition. The system comes with a metering pump, flow indicator, controller, liquid sump, pressure gauge, strainer & high pressure hose.

The pressure can be setinitially on the gauge, by manually varying the knob until the gas comes out. Once the setpressure is exceeded the excess pressure is released until the autoclave pressure becomes equalto or below the set pressure. The pressure release is slow & gradual & the set pressure can bevaried at any point.
High pressure autoclaves are provided with built in safety rupture disc, however additionalsafety can be offered by providing pressure safety valve for which release pressure can be setmanually by increasing or decreasing the spring tension or by simply changing the spring. Theset pressure should normally be around the design pressure. Safety relief valves are standardsupply for glass autoclave & shaker hydrogentor where rupture discs are not available for lowpressures. These valves come with PTFE / Kalrez O-rings.
