Description
Technical field
The utility model belongs to technical field of petrochemical industry, relates to a kind of Novel gas-liquid separator be applied in hydrogenation plant.
Background technology
Separator is indispensable unit in petrochemical plant, can be divided three classes by purposes, namely for the container of Liquid liquid Separation, for the container of gas-liquid separation and the container for cushioning.Wherein, gas-liquid separator is used for divided gas flow and liquid, makes the droplet carried secretly in gas under the gas compartment natural subsidence of container, to reduce liquid foam entrainment simultaneously.Common gas-liquid separator has following several: gs-oil separator, return tank of top of the tower, suction port of compressor divide flow container, gas pot (fuel gas divides flow container), emergency blow-down tank etc.Gas-liquid separator is divided into vertical vessel and horizontal vessel from structure.The liquid direction of motion in horizontal vessel is vertical with Action of Gravity Field direction, is conducive to sedimentation separation, and line stability is good; But its gas-liquid separation space is little, floor space is large, and high-order erection is inconvenient.And the gas-liquid separation space of vertical vessel is comparatively large, is conducive to being continuously separated of middle mixed layer, takes up an area little, high-order erection is convenient.
At present, existing gas-liquid separating method has following several: the separation of gravitational settling, split flow, centrifugation, silk screen separation, ultra-filtration and separation are separated with filler.But there is following problem in existing separation method: the equipment volume of gravitational settling is huge, and separative efficiency is low, and segregational load is low, and separating ranges is narrow, but equipment does not simply need internals; The separative efficiency that centrifugal force separate is separated with baffling lower (separable comparatively droplet), segregational load is higher, and separating ranges is wider, and equipment volume is less, can be used for high-tension apparatus; Filler is separated, silk screen is separated and the separative efficiency higher (separable droplet) of ultra-filtration and separation, but segregational load is low, and separating ranges is narrow, easily by the liquid of net take away, and easily to block up.
Traditional gravity separator wants to keep good separating effect, need control its liquid level and pressure.The control of conventional separators liquid level and pressure adopts constant DP control technology.In the pressure changeable level control of separator, utilize float liquid level controller to drive oily gentle control valve, make its teamwork, control the liquid measure of liquid and gas, complete the adjustment to liquid level in separator, and the pressure of separator is not controlled.The level control method of pressure changeable farthest can reduce the throttling of oil gas vent valve, reduces the pressure of separator, improves separating effect.
CHEVRON LUMMUS GLOBAL (CLG) develops a kind of novel vertical separator, internals have inlet tube annular to cover oblique ring, wear strip, annular retaining ring, biphase gas and liquid flow is utilized annularly to cover in oblique ring flow process, the centrifugal force formed, liquid flows downward by gravity, and gas-liquid two-phase is separated.This structure separative element in hydrogenation plant is comparatively common, and separative efficiency is higher, reaches more than 80%, but in high-pressure system, internals more complicated, manufacture difficulty, cost is higher.
SEI (SEI) independent development tangential admission separator, the air-flow containing drop enters separator by tangential entry and makes high speed rotary motion therein.Drop is thrown to wall under the influence of centrifugal force, and gathering becomes large drop and flows downward along wall, completes and is separated with the first order of gas; Then air-flow is entered into by reflecting disc baffling in the riser at separator center, in riser under High Rotation Speed airflow function, tiny drop is thrown on tube wall and forms liquid film rotation rising, turn back to separator bottom space via the annular space on separator top vent pipe, outer circulating tube, complete the second-order separation of gas-liquid.But because entrance velocity is different, there is larger difference in the separative efficiency of separator, separative efficiency is between 60 ~ 80%.
