Accompanying drawing explanation
Fig. 1 is example structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
The feed(raw material)inlet for carrying the transport pipe 1 of mixed c 4 charging to connect extraction tower 2 in the present embodiment, the tower top outlet of extraction tower 2 connects the shell side inlet of First Heat Exchanger 3, the shell-side outlet of First Heat Exchanger 3 connects the feed(raw material)inlet of depropanizing tower 4, depropanizing tower 4 top gas phase outlet connection second interchanger 5 shell side inlet, second interchanger 5 shell-side outlet connects depropanizing tower return tank 6 entrance, and depropanizing tower return tank 6 water bag connects oil-water discharge tank 9 entrance.
For carrying the transport pipe 7 of de-salted water to connect water pump 8 entrance, water pump 8 exports and connects extraction tower 2 top de-salted water entrance; The outlet at bottom of extraction tower 2 connects oil-water discharge tank 9 entrance.
Extraction tower 2 in the present embodiment is dumped packing tower, and depropanizing tower 4 is ADV valve tray column, and the top of extraction tower 2 is provided with coalescer 21 near top exit.
Principle of work is described below:
The mixed c 4 raw material come from raw material tank field enters bottom extraction tower 2, through feed entrance sparger, sends in tower as disperse phase (light phase).
Extraction agent adopts de-salted water, pressurizes, send into extraction tower 2 top as external phase (heavy phase) through extraction water pump 8.
Mix in filler with as the water of external phase is full and uniform as carbon four raw material of disperse phase, counter-current extraction, major part methyl alcohol is soluble in water, extracting phase (carbon four) leaves mass transfer section and enters tower top settling section, carbon four drop reassembles, with the water drop wherein carried secretly under density difference effect, be separated into water-oil phase.The tower diameter of settling section expands as 3000mm by 2600mm, further reduces the flow velocity of carbon four raw material in extraction tower 2, is conducive to reducing carrying the water yield secretly in carbon four raw material.
Extraction tower 2 tower top arranges the thick coalescer 21 of one section of 600mm, when carbon four flows through coalescer 21 from bottom to top, the small water droplet carried in carbon four is tackled below coalescer 21 by the coalescer 21 with special hydrophobic nature, small water droplet is constantly accumulated into the globule, the larger globule relies on the downward sedimentation of self gravitation, thus realizes the effect of the coalescent dehydration of hydrocarbon medium.
Carbon four raw material is after counter-current extraction and coalescent dehydration, and methanol content is down to below 50ppmw, under differential pressure action, send into depropanizing tower from tower top.
Be the water containing methyl alcohol and a small amount of hydro carbons bottom extraction tower 2, be sent to oil-water discharge tank as waste water and first flash off a small amount of hydro carbons, then deliver to Quan Chang sewage farm.
Depropanizing tower is 68 layers of ADV valve tray column, tower top pressure controls at 1.8MPa, tower reactor temperature control 105.1 DEG C, and tower top temperature control is at 49.5 DEG C, in C 4 materials, most of moisture and C2, C3 cut enter return tank 6 after the second interchanger 5 condensing cooling of tower top, utilize the water bag of return tank 6 to remove.
