Definitions

  • the present invention relates to the distribution of a gaseous mixture conveyed in liquefied form in a tank from a production site to a site of use.
  • the present invention relates to a process for distributing a gaseous mixture in exactly required proportions, from separate storage of said constituents in the liquid state on the production site, which is mixed in the liquid state and transfer in a cryogenic tank of a transporter then, after transport, which is transferred to cryogenic storage on the site of use to be vaporized and distributed in the gaseous state according to demand.
  • the object of the invention is to develop a gaseous diaper in the perfectly homogeneous liquid state with contents of its constituents strictly in accordance with those of the gaseous mixture to be dispensed, and this by using simple, inexpensive, effective means. and safe to prepare the mixture in the liquid state.
  • This object of the invention is achieved in that the mixing of the constituents in the liquid state is carried out directly on a transfer line towards the tank of the transporter by drawing off by pump and valve of the said constituents in the liquid state out of said storage and this at flow rates roughly adjusted to their respective contents in the final mixture, passage of said flow rates in a static mixer, analysis sample on the mixing flow rate in liquid state and determination of the actual content of at least one constituent, action on a means for fine adjustment of the flow rate of said constituent according to a differential signal between a set value of said constituent and said measured value in order to constantly restore the content of this constituent to its exact set value , after which the mixture in the liquid state is introduced into the tank of the transporter.
  • the mixture consists essentially of two constituents and the constituent having the lowest target content is adjusted to its exact value.
  • the invention also relates to equipment for preparing a mixture of gases in the liquid state, of the type comprising, on the production site, elementary storage tanks for the said constituents in the liquid state, minus a transfer pipe with pump and coarse adjustment valve to a tank of a transporter, characterized in that the transfer pipe incorporates a static mixer, the inlet of which is connected to as many elementary pipes as there are storage tanks, while the single outlet pipe of said mixer is associated with a means for sampling and analysis of the content of at least one constituent of the liquid mixture, with means for processing the analysis signal compared to a set value and control means of a fine adjustment valve placed on the elementary pipe of the constituent analyzed downstream of the coarse adjustment valve, which are controlled by said means processing the analysis signal.
  • two nitrogen 11 and oxygen 21 storage units are respectively associated with a withdrawal pump 12 (22) sucking in at 13 (23) and discharging towards the pipe 14 (24) through a safety valve 19 (29) slaved to a non-return safety device 18 (28) associated with non-return valves 32-33.
  • Each pump recycles an excess flow via line 15 (25) and the recycling valve 16 (26) controlled by the pump discharge pressure by a regulator 17 (27), so as to carry out a rough adjustment of the nitrogen flows and liquid oxygen in lines 14 (24).
  • the pipes 14 and 24 meet at the inlet of a static mixer 34, but the oxygen pipe 24 incorporates a fine adjustment valve 24.
  • the outlet of the mixer 34 is connected to a pipe 35 which incorporates a sampling device of the liquid mixture 47 associated with an apparatus for measuring the oxygen content 36 which, by means not shown, delivers a control signal acting permanently on the fine adjustment valve 31 and if necessary on two solenoid valves 40 and 41 to prevent filling of the tank in the event of incorrect oxygen content in the mixture.
  • the assembly 37-38 makes it possible to obtain a mixing flow which is stable at the level of the sample 47 for the analysis 37 of the oxygen.
  • Line 35 ends with a connector 42 to a hose 44 of a tank 43 on a road vehicle 45.
  • a means 46 allows manual and simultaneous switching of the solenoid valves 40 and 41 to prevent filling of the tank 43.
  • nitrogen and liquid oxygen are simultaneously withdrawn from storage 11 and 21 by pumps 12 and 22, which send corresponding flow rates roughly adjusted by valves 16 and 26.
  • a flow d analysis is taken at 47 and immediately analyzed at 36 to determine the oxygen content.
  • This oxygen content is compared to a setpoint content - fixed between 21 and 23% for medical air, and feeds back with a very short response time - of the order of 10 seconds - on the fine adjustment valve 31 for correct any deviation of the oxygen content from the setpoint.
