Abstract

FIELD: organic chemistry. SUBSTANCE: origin hydrocarbon-containing fraction is separated into its components, the process takes place by single- or multi-stage partial condensation. Thus prepared fraction being enriched by CH, is affected by cracking. Cracking gas which is enriched by H/CH/CH, being affected by rectification method of separation. Thus prepared product is mixed with origin fraction and then is affected by separation into its components, in particular fraction which is enriched by CHbeing used. EFFECT: improves efficiency of the method.

Способ получения обогащенной С2Н4 фракции продукта из очищенной, в частности, освобожденной от СО2, и высушенной углеводородсодержащей исходной фракции, в частности, природного газа. При этом очищенная и высушенная углеводородсодержащая исходная фракция разделяется путем одно- или многоступенчатой частичной конденсации на свои отдельные компоненты, фракция этого разделения, обогащенная С2Н6, подвергается крекингу, и затем крекинг-газ, обогащенный Н2/С2Н4/С2Н6, подводится к такому же ректификационному способу разделения, как и углеводородсодержащая исходная фракция, и после перемешивания с ней разделяется на ее компоненты, в частности, также на обогащенную С2Н4 фракцию продукта.A method of obtaining an enriched C 2 H 4 fraction of a product from a purified, in particular freed from CO 2 , and dried hydrocarbon-containing starting fraction, in particular natural gas. In this case, the purified and dried hydrocarbon-containing starting fraction is separated by single or multi-stage partial condensation into its individual components, the fraction of this separation enriched in C 2 H 6 is cracked, and then the cracked gas enriched in H 2 / C 2 H 4 / C 2 H 6 , is brought to the same distillation separation method as the hydrocarbon-containing starting fraction, and after mixing with it it is separated into its components, in particular also into the C 2 H 4 enriched product fraction.
