Definitions

  • the invention relates to a method for transporting and storing acetylene according to the preamble of claim 1.
  • acetylene is usually transported and stored in steel bottles.
  • these steel bottles are completely filled with a porous mass, such as diatomaceous earth or pumice stone, which in turn contains a solvent to absorb the acetylene.
  • a porous mass such as diatomaceous earth or pumice stone
  • various other methods have been known in the past, for example from US Pat. No. 2,925,385, in which a porous mass in the container is dispensed with can, if the solvent is kept at a low temperature of - 76 ° C. In this case the partial pressure of acetylene in the gas space above the solution is very low and the tendency of acetylene to decay is correspondingly low.
  • the invention is therefore based on the object of providing a method for storing and transporting acetylene which permits a higher storage temperature than was possible hitherto and in which cooling capacity can thus be saved. Complex procedural steps should be avoided.
  • acetylene can be stored and transported in containers while maintaining a maximum partial pressure of 1.1 bar under safety-friendly conditions if the mass ratio between acetylene and the solvent does not exceed 0.25.
  • the storage temperature required for safety is only -50 ° C, so that less cooling is necessary to compensate for heat from the outside.
  • FIG. 1 It shows, as a container 1 for an acetylene-DMF solution, a steel bottle which is equipped with an ignition valve 2 which has nickel wires 3 as electrodes for ignition. A pressure sensor 4 is attached to the ignition valve 2 as a detector. There is an acetylene-DMF solution 5 in the bottle.
  • the bottles were evacuated, then the DMF was sucked in, pumped out again and then entered with acetylene while shaking.
  • the filling quantities were determined by weighing.
  • the volume fraction of the solution in the bottles was between 25 and 48%.
  • acetylene decay was initiated in a lying bottle by applying an AC voltage of 50 V.
  • the experimental pressure was set by tempering the bottle. Before the ignition, the gas space of the bottle has a known pressure. The ignition now triggers the decay reaction, which leads to an increase in pressure, which is measured with the pressure sensor. Since the decomposition reaction is exothermic, acetylene emerges from the liquid phase as a result of the heat of reaction, and causes a renewed pressure rise due to the decomposition, which becomes noticeable as a second pressure maximum.
  • Line 1 shows the mass ratios of acetylene and DMF in the solution.
  • line 2 are the outlet pressures (Po) specified before the ignition.
  • Lines 3 and 4 list the first pressure maximum (P1) after ignition and the second pressure maximum (P2), which is caused by the escape of acetylene from the solution.
  • DMF dimethylformamide
  • solvents such as acetone or solvent mixtures, such as are generally used for the transport of acetylene, are also suitable.
  • a container which is charged with acetylene under these conditions will be equipped with a pressure relief valve which responds to the total pressure and which allows a gas escape from the container if an acetylene partial pressure of 1.1 bar is exceeded.
  • a further gas such as nitrogen, is added to the gas phase in order to prevent oxygen from penetrating into the interior of the gas bottle.
