Definitions

  • the present invention relates to a unit for separating or liquefying a gas, which may optionally be mobile, and to a method for transporting and reassembling the unit.
  • Certain gas separation or liquefaction units and in particular small cryogenic nitrogen generators, are required to supply gas for a short period (a few years, for example less than 10 years).
  • the unit At the end of the gas supply period, the unit is if possible moved to serve another customer, in another location.
  • critical equipment To avoid these massive buried foundations, critical equipment (cold box) will be placed on a precast concrete block, and placed on the ground. Its function will only be to statically take over the load of the equipment placed on it according to the nature and bearing capacity of the soil. Resistance to meteorological or seismic attacks will be ensured by the presence of at least three stay cables which will each connect the cold box to at least one prefabricated concrete block and itself placed on the ground. Each of the N stay cables constituting the system will be arranged in such a way that they form between them an angle substantially equal to 360 / N degrees.
  • a unit for separating and / or liquefying a gas comprising at least one enclosure, optionally isolated, of slender shape, characterized in that the enclosure is arranged on a first block concrete and the enclosure is anchored to the ground by means of at least three stay cables, each connected to a second separate concrete block, the second concrete blocks connected to the stay cables being arranged on the ground at the angles of a polygon, the first and the second blocks having a depth below the ground reference level not exceeding 1m, preferably 0.7m, typically 0.5m.
  • a method of transporting and reassembling an enclosure of a unit for separating or liquefying a gas as described above in which the enclosure is transported and possibly the first and / or at least one of the second concrete blocks from one site to another and the enclosure is reassembled on a / the first block, using guy ropes attached to / the second blocks to keep the enclosure in square.
  • enclosure E is placed on a concrete block 1, here illustrated with a square section, (but any other geometry would be suitable, for example a rectangle or an octagon) placed on the ground and whose depth below the reference level of the ground does not exceed 1m, preferably 0.7m, typically 0.5m.
  • Block 1 is preferably prefabricated.
  • the enclosure E can be a distillation or washing column or a liquefaction device. It can be insulated by a vacuum space around the column or kept inside a cold box filled with powdery insulation.
  • the enclosure is held in place by three guy ropes 3 attached to three points of the enclosure at the same height preferably but at an angle of 120 ° around the periphery of the enclosure, if it is cylindrical.
  • the enclosure has a height H above the ground reference level and a perimeter P around the enclosure, in a direction perpendicular to the height, the ratio between H and P being greater than 1.5, or even greater than 2.
  • the stay cables are attached to three concrete blocks 2 placed on the ground, each at approximately the same distance from the block 1. However, to take into account the layout of a site or the prevailing winds, the stay cables can be of different lengths and blocks 2 can be at different distances from the block 1.
  • the blocks 2 are preferably prefabricated.
  • Other elements 4 of the separation or liquefaction apparatus are arranged near the blocks 1, 2, which may be a unit for compressing a gas intended for or coming from the enclosure, a unit for purifying a gas. gas intended for or coming from the enclosure, a heat exchanger for modifying the temperature of a gas intended for or coming from the enclosure.
  • the guys 3 are connected to points of the enclosure E located at a height above the ground of between 0.5H and 1H.
  • the blocks 2 are arranged on the ground forming the points of an equilateral triangle but for a more general case the second concrete blocks connected to the stays being arranged on the ground at the angles of a regular or irregular polygon.
  • This polygon can be for example an isosceles triangle, a square, a rectangle, a pentagon etc.
  • shrouds 3 form between them on the horizontal plane angles of 120 °.
  • the maximum dimension of each of the first and second blocks 1, 2 is less than the height of the enclosure E and the weight of each of the first and second blocks 1, 2 is less than the weight of the enclosure E.
  • At least one of the second blocks 2 serves as a support for an element of the separation and / or liquefaction unit other than the enclosure E.
  • a compressor for a gas intended for or coming from the enclosure a storage, a turbine for a gas intended for or coming from the enclosure, a unit for purifying a gas intended for or from the enclosure, a heat exchanger to modify the temperature of a gas intended for or coming from the enclosure, a weather station, an office etc.
  • At least one solid is transported, it is possible to choose its dimensions in order to be able to transport it (s) with the enclosure, for example in the same container.
  • Position marker systems will then be used to be able to position the various equipment, mainly including enclosure E, the compressor (s), the gas purification system, on their respective concrete blocks so that the concrete blocks are laid out in exactly the same way between the two sites.
  • the connection of pipes between the equipment is therefore identical from one site to another.
  • the way of securing the enclosure is of particular interest for a mobile unit but can also be an inexpensive technique for maintaining an enclosure permanently at a single site.
  • the enclosure can operate at a temperature below 0 ° C., for example at a cryogenic temperature.
