Definitions

  • the invention relates to a process and an apparatus for the separation of light-boiling components from a hydrocarbon stream, particularly for the separation of a C 2 fraction from a C 3 + fraction to be obtained as target product, e.g. in the dehydrogenation of light hydrocarbons, but also suitable for other separation tasks within the range of C 1 to C 4 .
  • distillation column is referred to and operated as a de-ethanizer because all substances of boiling points less or equal to that of ethane are separated overhead by this de-ethanizer.
  • the feed mixture Before entering the coldbox, the feed mixture is cooled down to approx. ⁇ 25° C.
  • the condensate gained is passed directly into the de-ethanizer. Vapours that have not condensed are further cooled to approx. ⁇ 90° C. in the coldbox, the product-enriched condensate thus obtained also being directed to the de-ethanizer after heat exchange.
  • the coldbox therefore performs a one-step rough separation.
  • the remaining vapour phase basically comprising uncondensable components, e.g. hydrogen, is depressurised after heat exchange in the flow entering the coldbox.
  • the light-boiling substances cool down to approx. ⁇ 110° C. due to the Joule-Thompson effect. This temperature level is used to partially condense the stream entering the coldbox.
  • the uncondensed light-boiling substances are basically free from C 3 + components.
  • Evaporating propane or propene can be used at ⁇ 30° C. as a cooling agent for cooling the feed mixture before it enters the coldbox, for operating the coldbox and for cooling the de-ethanizer.
  • the generation of cold for such a process is extremely expensive.
  • the aim of the invention is, therefore, to provide a process and an apparatus by which the consumption of cold can be reduced to a significant degree.
  • the aim of the invention is achieved according to the main claim by a process for the separation of a feed mixture
  • the distillation apparatus comprises three to five successive condensation stages, each of a different temperature level.
  • the condensation stage of the lowest temperature level is operated at a temperature between ⁇ 120° C. and ⁇ 70° C. and a pressure of at least 2 MPa absolute, preferably at least 3 MPa.
  • the mixture which leaves the distillation apparatus as lower-boiling fraction is depressurised, the mixture thereby cooling down further under exploitation of the Joule-Thompson-effect, and thus being used to cool the condensation stage with the lowest temperature level.
  • the depressurisation is performed by an expansion turbine.
  • the process is used for feed mixtures containing less than 2 mol-% each of carbon dioxide and water or water vapour.
  • the feed mixture used is a reaction mixture from the catalytic dehydrogenation of hydrocarbons.
  • the segment of the distillation apparatus through which that part of the feed mixture that has condensed in the condensation stage of the highest temperature level is passed to the outlet means for the higher-boiling fraction, is provided as a stripping section of the distillation apparatus.
  • feed mixtures of a relatively small content of components of low boiling point are preferably fed at a point below the condensation stage of the highest temperature level and feed mixtures of a relatively high content of components of low boiling point are preferably fed at a point above the condensation stage of the highest temperature level.
  • condensation stages are provided in the form of condensers.
  • condensation stages are cooled by cooling water, evaporating ammonia, propane, propene and/or by exploitation of the Joule-Thompson effect when depressurising process gases.
  • the heating device is operated by external waste heat.
  • the distillation apparatus consists of one single distillation column or consists of a cascade of several distillation columns in which condensers are installed between the distillation columns.
  • the distillation apparatus comprises 3, 4 or 5 successive condensers, each being operated at a different temperature level.
  • the intermediate condensers are operated at temperature levels of approx. +45° C., +15° C. and ⁇ 30° C., respectively, which is a further advantage of the invention.
  • the main part of the rising vapours in the column if used, therefore condenses before entering the column head condenser and flows downwards as liquid.
  • the coldness level necessary for operating the column head condenser about ⁇ 80° C., and the related condensation performance can be produced by depressurising the high-boiling substances within the apparatus itself, which is a further advantage of the invention.
  • FIG. 1 shows an embodiment of the inventive process, in which the distillation apparatus consists of one single distillation column and several intermediate condensers;
  • FIG. 2 shows an embodiment of the inventive process, in which the distillation apparatus comprises a stripping section and a rectifying section separately of each other;
  • FIG. 3 shows an embodiment of the inventive process, in which the distillation apparatus comprises three sections with intermediate condensers between these sections.
  • vaporous feed mixture 1 can be cooled down first to 15° C. in an ammonia vaporiser 2 , for example.
  • the obtained C 2 fraction 4 is cooled down further to about 10° C., making part of the vapour condense.
  • Vapour phase 5 and condensate 6 are fed separately into the distillation apparatus.
  • the inlet can also be above the condensation stage of the highest temperature level.
  • first condenser 9 which is designed as a two-piece condenser located above the feed tray, cooling water and ammonia being used one after the other as cooling agents. Further rising vapours are partly liquefied in second condenser 10 , which is operated with propane or propene as cooling agent so that only a small part of the vapours arrives at head condenser 11 .
  • the vapours not condensed in head condenser 11 constitute the C 2 fractions 12 and 13 which are depressurised after the condensation in expander 14 , hereby cooling down to about ⁇ 125° C.
  • This cooled vapour 15 is used as cooling agent for the cold side of head condenser 11 , where it heats up to about ⁇ 50° C.
  • C 2 fraction 4 is conveyed through heat exchanger 3 for cooling feed mixture 1 .
  • the liquid flows downwards in stripping column 16 and is partly evaporated again.
  • the non-evaporated part is drawn-off as a C 3 + product 8 at the bottom of stripping column 16 .
  • the vaporous light-boiling substances 17 flow into first condenser 9 , which is designed as a two-piece condenser, where they partly condense, cooling water and ammonia being used as cooling agents one after the other.
  • Condensate 18 and vapours 19 are given into rectification column 20 .
  • Part of the bottom product of rectification column 20 is used as reflux 21 for stripping column 16 .
  • vapours not being condensed in head condenser 11 constitute the C 2 fractions 12 and 13 which are depressurised after the condensation in expander 14 , hereby cooling down to about ⁇ 125° C.
  • This cooled vapour 15 is used as cooling agent for the cold side of head condenser 11 , where it heats up to about ⁇ 50° C. Subsequently this C 2 fraction 4 is conveyed through heat exchanger 3 for cooling feed mixture 1 .
  • first condenser 9 which is designed as a two-piece condenser, where they partly condense, cooling water and ammonia being used one after the other as cooling agents.
  • Condensate 18 and vapours 19 are given into first rectification column 22 . Part of the bottom product of first rectification column 22 is used as reflux for stripping column 16 .
  • Second condenser 10 which is operated with propane or propene as cooling agent, condensate and vapours are led into second rectification column 23 .
  • the bottom product of the second rectification column 23 serves as reflux for the first rectification column 22 , in this way only a small part of the vapours arrives at head condenser 11 .
  • Vapours not having condensed in head condenser 11 constitute C 2 fractions 12 and 13 which are depressurised after the condensation in expander 14 , hereby cooling down to about ⁇ 125° C.
  • This cooled vapour 15 is used as cooling agent for the cold side of head condenser 11 , where it heats up to about ⁇ 50° C. Subsequently this C 2 fraction 4 is conveyed through heat exchanger 3 for cooling feed mixture 1 .
  • this last variant involves the advantage that only the upper part of the second rectification column must be of a design resistant against low temperature and insulated more strongly against heat transfer, which is one of the advantages of the invention.
  • the propane refrigeration capacity is about 55% less so that the compressor capacity for the propane refrigeration circuit is about 50% less and the compressor can be of a correspondingly smaller size.
