Abstract
Degassing filled column, its inner main structure that can be used for aspects such as stabilization of crude oil, desalinization, gas desorption is that liquid sprayer, liquid distribution trough, degassing filler and bulb preventing device, this tower are used for the more board-like degassing tower of stabilization of crude oil and have significantly advantage, the degassing efficiency height, operation is reliable, and can bring high economic benefit.
Description
The present invention belongs to gas-liquid separation device.
Adopt the device of negative pressure flash distillation stabilized crude (oil) at present both at home and abroad, its key equipment is vertical or horizontal board-like flash column (degassing tower), and this tower internal structure mainly is flusher and column plate.Because the crude oil decentralization that flusher sprays is little; Crude oil liquid layer thickness on column plate is big, and its influence of static pressure is big, and the liquid layer Surface Renewal is poor, and gas is difficult for deviating from the surface of liquid; Liquid layer at the bottom of the dirty hydraulic shock tower of column plate bubbles, and causes reasons such as gas enclosure loss, and the degassing efficiency of tower is low, and the lighter hydrocarbons recovery amount is few.
The present inventor is engaged in the teaching and the research work of separation equipment for many years, and having had not yet to see the books and periodicals periodical has the present invention.
The objective of the invention is to be to improve the degassing efficiency of degassing tower (flash column), increase the light hydrocarbon recovery rate in the stabilization of crude oil process.
Fig. 1 is the main organigram in the inside of degassing filled column of the present invention, and wherein 1 is flusher; The 2nd, liquid distribution trough; The 3rd, the degassing filler layer; The 4th, bulb preventing device.
Flusher is one and is made of cylindrical body, offers the hole of some on it. Crude oil with certain pressure and temperature sprays thus and nebulizes, and increases the decentralization of crude oil, can improve the sprinkling degassing efficiency. The crude oil that sprays, collected by the liquid distribution trough of dividing into, and then distribute to following degassing filler layer equably. This liquid distribution trough is one group of uncovered bathtub construction, and its groove width and length equidimension are decided according to degassed material dimensions. The crude oil that is got off by distributor flows to the degassing filler layer. This degassing filler layer is to be stacked together by some layers of regular degassing filler. Every layer of regular degassing filler is that its both sides are provided with the lip ring of certain altitude by each other parallel and maintain the distance of 5～200mm and consist of with the multi-disc thin plate of tower center line inclination certain angle, and this plate is provided with the duct, rises air flue and communicates with main. The height of degassing filler can 150～300mm. Its width and length are decided on the internal diameter of tower, but require to maintain with the tower internal diameter arch area of one fixed width, in order to consist of the main air flue that rises of deviating from gas. Its angle of the linking of adjacent two-layer degassing filler is between 70 °～120 °. The packing layer that degassing filler stacked by this spline structure, then can form some the W shape gas-liquid runners with certain-length, in this runner, crude oil is dirty with W shape path on the filler thin slice, gas under the filler thin slice to rise on the W shape path, Liquid Flow does not interfere with each other, and crude oil forms easily thin liquid layer and carry out Surface Renewal on runner, therefore can greatly improve the mobile degassing efficiency of crude oil. The flow through crude oil of packing layer again through bulb preventing device, flows at the bottom of the tower. This bulb preventing device is one group, and to tilt with the tower center line be that 30 °～60 ° deflector consists of. Crude oil along this deflector plate surface current to tower at the bottom of, avoided having reduced the tolerance that liquid phase is carried secretly because liquid level at the bottom of the dirty gravity impact tower of liquid produces a large amount of bubbles, can reduce entrainment loss.
Performances such as in sum, degassing filled column has the degassing of good spraying film, flow in the gas-liquid shunting and anti-foam.The degassing efficiency height can improve about 5～20% than board-like degassing tower, and has and make easy for installationly, can be designed to and the advantage of two kinds of operating structure forms of stream or adverse current.
Degassing filled column is not only applicable to the stable of crude oil, but also can be used for the single-stage of desalinization, gas desorption etc. or multistage degasification process.If this tower is used for the crude oil stabilizer that treating capacity is 10,000 ton per days, single tower year economic benefit can reach hundreds thousand of units even more than 1,000,000 yuan.
