Definitions

  • the invention relates to a winter-proof turbocompressor unit and to a method for winterizing the turbocompressor unit.
  • a turbo-compressor is used in a chemical plant of the chemical industry.
  • the chemical plant is located in a special location, which can be determined, for example, by the occurrence of a mineral resource.
  • the resource is, for example, natural gas that is produced in a climate zone characterized by low temperatures, such as a tundra. Temperatures in the tundra are just over freezing during the summer months, and temperatures are still below freezing during the winter months.
  • the turbocompressor is equipped to be fitted so that it is safe and trouble-free operation at low temperatures, especially during the winter months.
  • a conventional turbocompressor unit 101 is shown.
  • the turbocompressor unit 101 has a turbocompressor 102 which has a rotor 103.
  • the rotor 103 is mounted with bearings 104, for example with Kippsegmentgleitlager.
  • the Kippsegmentgleitlager 104 are oil lubricated.
  • the turbocompressor 101 has an oil supply system 107 with an oil feed line 108 and an oil return line 109.
  • the oil supply line 108 is connected to the one oil supply manifold 105 of the turbocompressor 102, via which the lubricating oil 113 is supplied to the tilting pad plain bearings 104.
  • the turbocompressor 102 For discharging the lubricating oil 113 from the Kippsegmentgleitlagern 104, the turbocompressor 102 has an oil return manifold 106 which is connected to the oil return line 109 is connected. Furthermore, the oil supply system 107 has an oil tank 110 which is filled with the lubricating oil 113. For filling the oil tank 110, a filler neck 111 is provided on the oil tank 110. In the oil tank 110, an oil pump 112 is installed, with which the lubricating oil 113 is conveyed to the Kippsegmentgleitlagern 104 via the oil supply line 108 and the oil supply manifold 105.
  • the turbocompressor unit 101 is housed outdoors, so that the turbocompressor unit 101 is exposed to the outside temperatures of its location. If the turbocompressor unit 101 is located in a tundra, the outside temperatures are at least temporarily so low that the lubricating oil 113 is not usable for the operation of the turbocompressor 102, ie the lubrication of the tilting pad plain bearings 104. Therefore, the turbocompressor unit 101 is provided with means for allowing the turbocompressor unit 101 to operate even at the low outside temperatures. These facilities are a thermal insulation 114 (in Fig. 2 shown schematically), with which the oil supply line 108 is thermally insulated. Furthermore, the oil tank 110 has an oil heater 115, with which the lubricating oil 113 is heated in the tank 110 to a necessary operating temperature. The oil heater 115 is conventionally powered by electric power.
  • the provision of the heat insulation 114 and the oil heater 115 is expensive in the production of the turbo compressor unit 101 and costly. If the oil heater 115 fails at low outside temperatures, the lubricating oil 113 in the oil tank 110 can no longer be brought to the required operating temperature, so that the turbocompressor unit 101 has to be switched off. Remedy could provide appropriate safety-relevant facilities to make the oil heater 115 fail-safe here. These facilities require increased engineering effort in the design and construction of the chemical plant, as well as increased capital expenditures.
  • the object of the invention is to provide a winter-proof turbocompressor unit and a method for winterizing the turbocompressor unit, which is safe to operate at low outside temperatures, the engineering effort and investment costs are low.
  • the winterized turbocompressor unit has a turbocompressor and an oil supply system for supplying the turbo-compressor with a lubricating oil, wherein the lubricating oil is a cryogenic oil and the turbocompressor and the oilsupply system are set up for operation with the cryogenic oil.
  • cryogenic oil in the turbocompressor unit with the turbocompressor and the oilsupply system for supplying the turbo-compressor with the cryogenic oil is used as the lubricating oil, the turbocompressor and the oilsupply system being arranged for operation with the cryogenic oil.
  • the method according to the invention for winterizing the turbocompressor unit with the turbocompressor and the oil supply system for supplying the turbocompressor with the lubricating oil comprises the step of: charging the cryogenic oil into the oil supply system as the lubricating oil.
  • the lubricating oil is of the type of cryogenic oil whose minimum possible operating temperature is lower than that of a conventional lubricating oil. Therefore, the lower temperature oil can be used at lower temperatures to operate the turbocompressor unit than would be possible with the conventional lubricating oil. Such low temperatures are, for example, the outside temperatures in a cold climatic zone, such as a tundra during the winter months.
  • the turbo compressor unit does not need measures for heating and / or keeping warm the Lubricating oil to be equipped, such as an oil heater, which could keep the lubricating oil to temperature, and / or thermal insulation of oil lines. This results in a low effort in engineering the turbo compressor unit and low investment costs. Furthermore, when operating the turbocompressor unit, it is unnecessary to take into consideration a too low temperature control of the lubricating oil, so that the operation of the turbocompressor unit is simple.
  • the low temperature oil is an oil according to ISO VG 46 and has a low pour point at -54 ° C and a suitability as a lubricating oil at up to 20 ° C.
  • the turbocompressor unit which is operated with the cryogenic oil, can thus be advantageously operated safely up to an outside temperature of up to -20 ° C, without additional measures, such as a heat insulation of oil lines and / or oil heating need to be provided.
  • the low temperature oil is an oil according to ISO VG 46 and has a low pour point below -54 ° C and a suitability as a lubricating oil at -30 ° C.
  • the turbo compressor unit can be operated with the lubricating oil at an outdoor temperature up to -30 ° C, without additional measures, such as heat insulation of oil lines and / or oil heating need to be provided.
  • a turbocompressor unit 1 has a turbocompressor 2, which has a rotor 3 for compressing gas.
  • the rotor 3 is supported by bearings 4.
  • the bearings 4 are Kippsegmentgleitlager, which are supplied to the lubrication with lubricating oil 13.
  • the lubricating oil supply is accomplished by supplying the lubricating oil 13 through an oil supply manifold 5 and discharging the lubricating oil through an oil return manifold 6.
  • the turbocompressor unit 1 also has an oil supply system 7 with an oil supply line 8 and an oil return line 9 for supplying the bearings 4 with the lubricating oil 13.
  • the oil supply pipe 8 is connected to the oil supply manifold 5 lubricating oil
  • the oil return line 9 is connected to the oil return manifold 6 lubricating oil.
  • the oil supply system 7 has an oil tank 10, to which both the oil supply 8 and the oil return line 9 are connected.
  • the oil tank 10 has a filling with the lubricating oil 13 and a filler neck 11, through which the lubricating oil 13 has been filled in the oil tank 10.
  • the oil tank 10 has an oil pump 12 installed to supply the lubricating oil 13 to the oil supply pipe 8 in the oil tank 10.
  • the lubricating oil 13 is sucked from the oil tank 10 and conveyed into the oil supply 8. From the oil supply line 8, the lubricating oil 13 is fed into the oil supply manifold 6 and brought to the bearings 4 to the lubrication. From the bearings 4, the lubricating oil 13 runs in the oil return manifold 6 and in the oil return line 9 to then return to the oil tank 10. Thereby, by the oil pump 13, the oil supply 8, the oil supply manifold 5, the oil return manifold 6, the Oil return line 9 and the oil tank 10 formed an oil circuit.
  • the lubricating oil 13 is a cryogenic oil, for example the oil "Shell Corena AS, ISO VG 46".
  • the residence time is so long that the lubricating oil 13 in the oil tank 10 assumes the ambient temperature of the oil tank 10. If the lubricating oil 13 passes the bearings 4, the lubricating oil 13 in the bearings 4 is heated due to friction effects in the bearings 4. The thus heated lubricating oil 13 is then fed via the oil return manifold 6 and the oil return line 9 back into the oil tank 10. There, the heated lubricating oil 13 cools down again to the ambient temperature of the oil tank 10.
  • the turbocompressor 2 can be operated safely and without damage up to an ambient temperature of the turbocompressor unit 1 at up to -20 ° C. ambient temperature.
  • the turbocompressor unit 1 is safe to operate in a climatic zone in which the ambient temperature does not drop below -20 ° C.
