    3000nm3/h Nitrogen Plant Air Separation Plant Centrifugal Compressor Unit

     

     

    1. Specific requirements

    5.4.17. Centrifugal compressor units should be equipped with control, alarm and blocking systems, taking part of anti-damage system, which should span into action while these values are exceeded. Operational procedure of compressor stopping and standby switching is specified by compressor unit operation algorithm developer.

    5.4.18. The control is needed over at least the following parameters:

    - gas t° at suction of all stages

    - gas t° at pumping of all stages

    - water t° at the compressor unit inlet

    - water t° at the outlet of each refrigerator

    - oil t° in the oil tank

    - oil t° at the oil refrigerators inlets/outlets

    - bearings t°

    - gas pressure at suction and at pumping of each stage

    - oil pressure before oil refrigerator

    - oil pressure before and after the oil filter (drop)

    - lubricating oil pressure in collector and at each point of its supply

    - sealing oil pressure at each point of its supply

    5.4.19. Warning alarm system should be used at least for the following parameters:

    - while suction pressure drops

    - while the last stage pumping pressure raises

    - while oil and cooling water pressure drops

    - while level in separators raises

    - while rotor vibration level raises and axial thrust increases

    - while pressure differential increases at oil filters

    - while decreases differential pressure “sealing gas-gas” or “sealing oil-gas”

    - while oil level in oil tank drops

    - while oil t° increases or decreases after oil refrigerators

    5.4.20. Alarm warning and blocking should cover at least the following parameters:

    - while suction pressure level drops below acceptable value

    - while differential pressure level “sealing gas-gas” or “sealing oil-gas” decreases below acceptable value

    - while suction pressure level increases over the acceptable value

    - while the rotor axial thrust value increases

    - while cooling water pressure level drops below the limiting value and while where is no water flow

    - while oil pressure level drops below the limiting acceptable value and while there is the minimal oil level in oil tanks

    5.4.21. Except the above mentioned safety interlocks, should be at least provided interlocks, which do not allow to start the compressor while:

    - suction pressure is below the acceptable value

    - low differential pressure “sealing gas-gas” or “sealing oil-gas” and low pressure in lubricating system (below the acceptable value) and while oil level in oil tank is below the minimum possible value

    - cooling water low pressure and absence offlow hole

    - hooking of jacking gear with rotor shaft

    - oil lack in oil vessel

    - non-conformance of bearings t° to designed values

    5.4.22. Blocking actuating for stopping the compressor should be done while blocking values are reached at minimum 2 anti-damage devices.

    5.4.22. Explosion protection level of electrical means should correspond to the category and group of explosive mixture at their installation place.

    5.4.23. The Supplier should provide the anti-surging system

    5.4.24. Shaft seals and corresponding sealing system of the centrifugal compressor unit should be designed to support the maximal pressure at the compressor outlet. Applicable mechanical seals, not depending on their type or configuration, should be of cartridge type, if other is not mentioned in the custom documentation for delivery.

    5.4.25. Clutch couplings should be of the safe multi-disc and buffer type, with stainless steel discs. While launching the electric motor shaft, the reducer, clutch couplings and compressor rotor, the system should bear the transition torques, related to the short circuit and/or to the repeated acceleration after the momentary power interruption.

    5.4.26. For the equipment, taking part of the compressor, it is necessary to provide the axial and side screw thrusters.

    5.4.27. If the electric motor is chosen as a compressor drive, the smooth starting device should be provided.

    5.4.28. Compressor, compressor drive and reducer should be mounted on the same base-plate, if there are no other requirements in the custom documentation. Base-plates should have vertical screws for level adjusting at the erection site.

    5.4.29. While choosing materials for assembly units and details manufacturing it is needed to consider the pressure, temperature (maximal and minimal), media character and chemical composition, materials processing characteristics and corrosion resistance.

    5.4.30. Materials quality and characteristics should be confirmed by the enterprise-supplier in related Certificates. In case of absence of accompanying Certificates for materials or information about any trials types, the trials should be done at the equipment manufacturing company in accordance with standards or specifications requirements for such materials.

    5.4.33. The compressors common SPTA (spare parts, tools and accessories):

    - sealing rings, cuffs – 1 set

    - filtering elements – 3 sets

    - reducer bearings – 1 set

    - resilient elements for plate clutches – 1 set

    - fingers for clutches – 1 set

    - backup sealing for each installed static gasket (housing, bearing support etc) – 4 sets

    - isolators (for 6 kW electric motor) – 2 sets

    - 10% of each type of control and measuring apparatus (but not less than 1 pc of each type)

    - 10% (but not less than 2 pcs) of each type and size of built-in nuts and studs.
