Coal chemical industry conversion low-temperature condensate steam stripping process

The invention discloses a coal chemical industry conversion low-temperature condensate steam stripping process which comprises the following steps: S1, acquiring low-temperature conversion condensateseparated by a conversion separator, and preheating the conversion condensate; S2, introducing the preheated conversion condensate into a stripping tower from the middle part, and introducing low-pressure steam into the stripping tower from the bottom; S3, carrying out reverse contact stripping on the conversion condensate and low-pressure steam in a filler or tower tray of a stripping section, carrying out reverse contact stripping on stripping gas after stripping and a tower top condensate reflux in a filler or tower tray of a rectifying section, and rectifying the reflux; S4, condensing therectified stripping gas through a tower top condenser, sending the condensed and separated stripping gas to a downstream device, and enabling the separated reflux liquid to flow back to the rectifying section; by changing the
