DESCRIPTION

CHARACTERISTIC FEATURES OF THE PLANT

The air separation plant is constructed and designed for unattended operation. Only occasional inspections are necessary.

Operating changes with longer periods of time will be controlled manually, i. e. start-up, shut-down or deriming of the cold box. The plant consist of several units (packaged). These units, including all operation devices and all control devices, are designed for outdoor erection and are provided with noise- and weather protection. 1 air compression and purification unit ACP 1 oxygen and nitrogen generating box ONP Main advantages of this plant conception are workshop-mounted units, no bulding requirements, simple foundation work, short erection time and therfore low erection as well as civil work costs.

Constructional premises are a well prepared site including approach roads, foundations for all units and compressors, utility supply and drainage.

TECHNICAL DATA:
 

Basic data for design and acceptance: Barometric pressure: 1,013 bar Air temperature: 35°C Relative humidity: 0-100% Air condition: Normal industrial air, free of dust, oil, abnormal contents of hydrocarbons and other corrosive elements as well as other components as normally. Carbon dioxide content 300 ppm. Cooling water temperature: max. 10°C Normal chemical composition of water for industrial purposes with a total hardness of under 18° dH (German degrees of hardness), free of algae and iron compounds. Cooling water pressure: min. 6 bar abs. Compressor delivery pressure: 14 bar bas. Electricity supply: 400 V, 3 phase, 50 Hz

For actual operation of the plant under tropical conditions, the plant design shell allow a certain variation of the basic data as given above (i. e. concerning temperatures of cooling water and air temperatur and humidity). Such deviations at the time of acceptance shall be taken into account using acknowledged technical rules.

The design of the plant allows full flexibility between the production of gaseous oxygen and gaseous nitrogen.
 

UTILITIES:

Energy consumption:
(measured at motor shaft rsp. heaters at terminal with a tolerance of +/- % without liquid storage and product handling equipment)

Air compressor incl. Cooling fan:   118 kW Molecular sieve unit (average):          5 kW Others:                                                 5 kW Total approx.                                    128 kW Cooling water requirement: Cooling water requirement approx.  4m3/h Regeneration gas: For rgeneration of molecular sieves waste nitrogen will be used from the process unit. Deriming gas: For total deriming of the unit, air from the air compressor will be used.

Operation:
Time required for deriming approx.:   12 hours
Time for cooling down process unit after total derimng approx.:   15 hours

Personnel requirements:
It is suggsted to control the air separation plant two times per shift, cylinder filling not included.
