Definitions

  • the present invention applies to denitrogenation processes of natural gas with or without helium recovery according to the preamble of claim 1 and known from the document US-A-4,758,258 .
  • the exploited natural gas fields contain more and more nitrogen. This is particularly due to the depletion and scarcity of fields rich enough that no enrichment treatment is necessary before the marketing of gas.
  • Unconventional resources such as shale gas also have the same problem: to make them marketable, it may be necessary to increase their calorific value by means of a pretreatment which consists of de-nitrogenising the raw gas.
  • US-A-4778498 describes a double column used for denitrogenation of natural gas.
  • Natural gas denitrogen units generally treat gases that come directly from wells at high pressure. After denaturing, the treated gas must be returned to the network, often at a pressure close to its inlet pressure.
  • the denitrogenation of natural gas uses cryogenic distillation techniques that take place at lower pressures than source pressures.
  • the sources can be at pressures of the order of 60 to 80 bara, while the cryogenic separation is carried out at pressures ranging from 30 bara to a pressure slightly above atmospheric pressure.
  • nitrogen purified natural gas is produced at low pressure and must be pumped and / or compressed to be introduced into the network.
  • the nitrogen-purified natural gas can be produced at different pressure levels at the outlet of the cold box.
  • the different streams are then compressed by external compression until the desired pressure is reached.
  • distillation at pressures greater than 12 bara is generally not well suited to the use of structured packings because of the "washing machine” phenomena, related to the approximation of the gas and liquid densities passing through the columns, which requires the use of trays for these pressure levels.
  • the invention consists in valuing the expansion of the natural gas in the different turbines of the process, using it to effect cold compression.
  • it may be product compression (typically natural gas purified by nitrogen).
  • it is the compression of a nitrogen enriched gas from a column of the column system. For example, the compression of the gas at the top of the high pressure column of a double column process makes it possible to reduce the pressure of this column.
  • the invention will be described in more detail with reference to the Figures 1 to 3 among which only the figure 3 illustrates a process according to the invention.
  • the process is carried out in an isolated cold box which contains an exchange line 1 and a double column 2,3 comprising a first column 2 operating at between 10 and 30 bara and a second column 3 operating at between 0.8 and 3 bara.
  • the first column 2 is thermally connected to the second column 3 by means of a vaporizer-condenser 5.
  • the exchange line comprises at least one heat exchanger, preferably brazed aluminum plates and fins.
  • the natural gas 10 which is generally at a pressure greater than 35 bara, cools in the exchange line 1.
  • a portion 11 of the natural gas representing between 1 and 80% of the gas to be separated, preferably between 5 and 55%, or even between 25 and 35% of the gas to be separated, is withdrawn from the exchange line 1 and is expanded in gaseous form in an expansion turbine 7 which produces a fluid that is sent to the bottom of the first column to separate.
  • the remainder of the natural gas 12 continues cooling in the exchange line where it is condensed, then is expanded in a flash valve before being sent in liquid form to the first column.
  • column 2 separates the gas natural in a liquid enriched methane 21 in the bottom of the column and a nitrogen-enriched gas at the top of the column.
  • the gas is used to heat the vaporizer-condenser 5 where it condenses and reflux at the top of the column 2.
  • the bottom liquid cools in a subcooler 4 and is expanded to be sent to an intermediate level of the second column 3.
  • An intermediate liquid 23 of the first column 2 is subcooled, expanded and sent to the top of the second column 3.
  • the waste nitrogen 18 is withdrawn at the top of the column and is heated in the exchangers 4.1.
  • Incondensable gases enriched in helium and nitrogen 17 leave the vaporizer 5 and heat up in the exchangers 4.1.
  • the methane-enriched liquid 13 of the second column 3 is withdrawn in the tank, pumped at high pressure by means of the pump 6, subcooled and then divided as flow 14 into three fractions.
  • a fraction 15A vaporizes in the exchange line 1 at the outlet pressure of the pump 6.
  • the fractions 15, 15B are expanded at different pressures from each other by valves and each vaporizes in the line exchange at a different vaporization pressure.
  • the fraction 15 leaves the exchange line as the gas flow 16.
  • the liquid 14 is divided in the same manner but the liquid 15 vaporizes in the exchange line 1, leaves it, is compressed in a cold in a CBP booster before being returned to the exchange line 1 to continue its warming.
  • This booster CBP values the energy of the turbine 7.
  • the liquids produced by the division of the liquid 14 vaporize in the same way as in the Figure 1 .
  • the nitrogen-enriched gas from the top of the first column 2 is compressed to a pressure of 17 to 30 bara in a cold booster CB1 having an inlet temperature generally below -150 ° C.
  • the compressed nitrogen serves to heat the vaporizer 5 where it condenses into a fluid 27 is expanded in a valve and returned to the top of the column 2.
  • the first and second columns can be replaced by a single column.
  • Natural gas to be treated 10 Natural gas to be treated, 11 Natural gas to be treated to turbine, 12 Natural gas to treat to expansion, 13 Low pressure liquid methane, 14 High pressure liquid methane, 15 Medium pressure liquid methane, 16 Medium pressure methane gas, 17 Mixture of nitrogen and helium, 18 Residual nitrogen.
