WEEKLY MAINTENANCE
7.1.1
LEAK DETECTION
It is necessary to perform a leak test when:
-
The user opens the reactor for replacing the catalyst bed
The user detects a problem in pressure control
To check the unit for leak, proceed as follows:
-
-
-
7.1.2
Put the pressure controller in manual mode, totally opened (100%).
Put the level controller in manual mode, totally closed (0%). Once the system is at
working pressure, it would be necessary to check if this valve is totally closed or if
it is necessary to recalibrate the zero point.
Put a tap in the gas outlet on the hot box and introduce an inert gas flow in the
system (He, N2, etc.). Put the unit at habitual working pressure.
Close the gas inlet, as well as the system on/off stopcock for gas and verify that
the pressure in the system remains constant over a period of time. If this is not the
case, use a soapy solution to locate possible leaks (subsequently dry the entire
system).
When the leaks has been detected and eliminated, clean the equipment,
removing the soapy solution.
CLEANING THE UNIT
For clearing the external of the unit, use a wet-cloth with water for preventing dust
accumulation.
For internal cleaning, it can be used water or any solvent (alcohol, acetone, etc.) for eliminate
soapy solution rest.
In case of cleaning with any solvent, the user has to manage properly the generated residues,
attending to its nature.
7.2.
MONTHLY – QUARTERLY MAINTENANCE
Depending on the use of the reactor and the reaction products the user should make a monthly
or quarterly maintenance, consisting on:
7.2.1
REPLACING THE FILTERS
The reactor is provided with two 15 microns filters that could get blocked as a consequence of
the continuous use. If that occurs, replace the filter by another one (Ref: Swagelok SG_SS-2F-15)
The replaced porous plate could be contaminated with hydrocarbons or other kind of
residues. The user of the unit must manage these residues, asking to an authorized manager and
attending to the environmental policy of the laboratory where it is being used.
