METHOD OF PRODUCING ETHYLENE-ENRICHED FRACTION OF PRODUCT FROM ORIGINAL HYDROCARBON-CONTAINING FRACTION |
摘要 |
FIELD: petrochemical processes. SUBSTANCE: method includes separation of purified and dried original hydrocarbon-containing fraction by means of single- or multistep partial condensation into separate components. Isolated ethane-enriched fraction is subjected to cracking process and hydrogen-ethane-ethylene- enriched cracking gas is introduced into the same rectification process as original fraction and in the mixture with the latter. EFFECT: reduced operational expenses due to the fact that only one low- temperature part of the process is available and thereby relaxation turbines can be eliminated. 5 cl, 1 dwg |
