Abstract

Metan bazli bir gaz akimindan kondensasyon ve siyirma sureti ile benzenin, diger aromatik maddelerin ve/veya diger daha agir hidrokarbon komponentlerin bertaraf edilmesine yönelik bir metod ve ilgili düzen. Prosesleme ekipmaninin kirlenmesinin ve tikanmasinin önlenmesi için benzenin ve diger aromatik maddelerin bertaraf edilmesi arzu edilir ve degerleri sebebi ile de diger daha agir hidrokarbon komponentlerin reküperasyonu istenir. Sogutulan besleme akimi (118) bir kolona (60) beslenir ve metan yönünden zengin bir buhar akimi (120) ve benzen/ aromatik maddeler/ agir maddeler de sivi (114) halinde ayrilir. Sivi madde (114) refrijerasyon reküperasyonu için bir isi esanjörüne (62) gönderilir. Ilik olan kuru gaz (108) isi esanjöründe (62) sogutulur ve kolona (60) siyirma gazi (109) olarak verilir.A method and related arrangement for the removal of benzene, other aromatic substances and / or other heavier hydrocarbon components by condensation and stripping from a methane-based gas stream. To prevent contamination and clogging of the processing equipment, it is desirable to remove benzene and other aromatic substances and, due to their value, the recovery of other heavier hydrocarbon components is desirable. The cooled feed stream 118 is fed to a column 60 and a methane-rich vapor stream 120 and benzene / aromatic substances / heavy substances are separated into liquids 114. The liquid 114 is sent to a heat exchanger 62 for reflux recovery. The warm dry gas (108) is cooled in the heat exchanger (62) and fed to the column (60) as a stripping gas (109).
