Introduction 1 Introduction The APOLLO® Vessel is a vacuum super insulated pressure vessel made of corrosion-resistant stainless steel. It is intended exclusively for storing nitrogen (cryogenic liquid nitrogen). The APOLLO® Vessel acc. to Directive for Pressure Devices 97/23/EG Category I Module A., with CE - marking This sign points out to dangerous situations resulting in possible • injury to persons • damage to the environment • damage to devices 1.
Vessel 2 Vessel 2.1 Main Components • • • • • • 2.2 Specifications of the Vessel Coaxial arrangement of the pressure vessel in the outer vessel with neck suspension and vacuum super insulation Pressure build-up device arranged in the vacuum room Chassis Safety valve Pressure gauge Dismountable siphon, Type EK® Manufacturer Cryotherm GmbH & Co.
Vessel 2.4 Examination of Safety Valve Examination Seat tightness and set pressure of the safety valve may only be examined by means of the bubble method outlined below. Contamination and corrosion of the valve mechanics are thus avoided. The set pressure is indicated on the type plate of the safety valve. 1. Admission of Test Pressure For the admission of the test pressure, a suitable testing device has to be used.
Vessel 2.7 Combined Positive Pressure Relief and Seal-off Device Caution! The positive pressure relief and seal-off device protects the vacuum room from overpressure. Re-evacuation may only be carried out by • manufacturer’s skilled staff The protective cover (2) intercepts the valve insert (1), when there is overpressure existing in the vacuum room. • Do not remove the protective cover (2). • Protect the valve from heat as well as cooling, as brittleness results in the loss of the operating vacuum. 2.

Safety 3.5 Accident Leaflet „suffocating Gases” ACCIDENT LEAFLET FOR ROAD TRANSPORTATION ADR/GGVS Class 2 CRYOGENIC LIQUEFIED GASES: suffocating non-toxic, non-caustic, non-inflammable, non-oxidizing – designation of the medium is indicated on the next page HAZARDS Heating results in pressure increase – danger of bursting. Gas is having a suffocating effect without any observable symptoms. The leaked liquid is very cold and evaporates rapidly.
Safety 3.6 Labelling The tanks have to labelled according to the regulations for hazardous goods for the respective employment. Cryogenic liquefied Gases suffocating, Class 2 Figure and Group 3A Figure and Group 3A Number, Labelling, Designation of the Medium 1977 1951 nitrogen, cryogenic liquid argon, cryogenic liquid Caution Marks No. 2 Non-combustible and non-toxic gas; 16 No. 11 This side up; This label has to be attached with the arrow heads pointing upwards.
Transportation and Assembly 4 Transportation and Assembly 4.1 General Transportation Transportation of the Vessel • Observe safety instructions. • Keep upright. • Lift and set down carefully. • Avoid impacts and strong shocks Transportation in filled condition • The vessel must be in excellent condition. • The vessel must be in unpressurized condition with loosely fitted transport stopper. • The EK Siphon has to be dismantled.
Operation 5 Operation 5.1 Initial Commissioning The vessel can be commissioned immediately after delivery. Caution ! • Observe safety instructions. • Use filling line with safety valve and pressure relief. • Wear gloves and safety glasses. • Protect the vessel from rolling away, tumbling down and damage. Note ! • When cooling down the hot vessel to operating temperature, increased evaporation losses do occur. 5.
Operation Disassembly of the EK Siphon Danger of Accidents! Dismantle the EK Siphon only with unpressurized vessel. 1. 2. 3. 4. Close the pressure build-up valve (7). Close the filling/withdrawal valve (3). Detach the connected withdrawal line from the EK Siphon. Open the waste gas/overflow (1) valve for relieving the pressure of the vessel. 5. Loosen the wing screw (8) and remove the straining ring (9) from the unpressurized tank. 6.
Operation Filling 1. Mount the EK Siphon. 2. Connect the filling line from the tank to the filling/withdrawal valve. 3. Open the waste gas/overflow valve for causing pressure relief. 4. Open the filling/withdrawal valve at the EK Siphon. 5. Open the tank valve for filling the vessel. 6. Close the tank valve when liquid nitrogen escapes from the waste gas/overflow valve . Caution! Risk of skin burns After completion of filling: Waste Gas/Overflow Valve (3) to leave open. 1. 2. 3. 4. 5.
Operation 5.5 Withdrawal of liquid Nitrogen Withdrawal 1. 2. 3. 4. Move the vessel to the place of withdrawal. Mount the EK Siphon. Mount the delivered transfer hose or a relevant filling line. Open the filling/withdrawal valve in order to withdraw liquid nitrogen. 5. Adjust the desired withdrawal pressure and open the pressure build-up valve for this purpose. Caution ! • Observe safety instructions. • Wear gloves and safety glasses. • Protect the vessel from rolling away, tumbling down and damage.
Operation 5.6 Pressure Build-up The operating pressure in the vessel allows for withdrawing the liquid gas. Vessel name Apollo® maximum operating pressure 1,3 bar The safety valve limits the maximum operating pressure. Should the pressure in the tank not be sufficient for the withdrawal operation, it can be increased by opening the pressure build-up valve. Prior to pressure build-up: • Check the EK Siphon for tight seat. • Adjust the operating pressure only as high as required. Pressure Build-up 1.
Operation 5.7 Pressure Relief Open the waste gas/overflow valve, until the operating pressure at the pressure gauge will be achieved. Subsequently, close the valve again. Do not direct the opening of the waste gas/overflow valve towards any persons or devices, as cryogenic gas causes burns and brittleness. 5.
Maintenance / Repair 6 Maintenance / Repair • • • • • • 24 With conventional use, the vessel does not require any special maintenance or attendance. Regular examinations with regard to operativeness and tightness of the fittings and screwings are recommended. Every two years, the safety valves have to examined with regard to function and set pressure. The pressure gauge indicates the set pressure. With conventional use, the vessel does not require any special maintenance or attendance.
Faults 7 Faults 7.1 General Faults Immediately put the vessel out of operation, in case that • the fittings are leaky. • the safety valve does blow off intensively. • the rate of evaporation is too high. • The outer cylinder is thawed / iced-up, which indicates loss of vacuum. In case of nitrogen escaping, • there exists the danger of suffocation. • open windows and doors. • leave closed rooms. Vessels with vacuum loss are useless and have to be returned to the manufacturer for examination / repair.
Faults 7.2 Possible Faults Fault Cause Iced-up valve This is operational with opened valve. - The valve is not closed completely. Close the valve (it thaws). The valve is leaky. Tighten the screwings / seat. If required, rinse / exchange the valve. Pressure build-up valve is open. Close pressure build-up valve. Pressure raising controller is too highly adjusted. Lower adjust the opening pressure of the pressure raising controller. Filling pressure is too high.
