Abstract
The utility model relates to a light hydrocarbon recovery unit, which comprises a plurality of cold traps and a plurality of receiving bodies, wherein the receiving bodies are connected by hoses in series; a condensation tube is arranged outside each receiving body, a ball valve is arranged at the entry of each condensation tube, and an outlet of the condensation tube is arranged inside the receiving body; a stainless steel tube provided with a ball valve is arranged at the top of each receiving body; and the receiving bodies are arranged in the cold traps, and refrigerant layers are arranged between the cold traps and the receiving bodies. The light hydrocarbon recovery unit is mainly applicable to various rectification devices, particularly to the light hydrocarbon recovery unit of a crude evaluation system. The temperature range of a refrigerant in the cold traps of the light hydrocarbon recovery unit is 0-30 DEG C. The light hydrocarbon recovery unit adopts a flexible receiving body series connection scheme, so the receiving bodies can be arranged in series for use as per the demand, and recovery of all light hydrocarbons can be ensured at a special phase of the device, for example, during evaluation of condensate oil with high content of light hydrocarbon.
Description
Technical field
The present invention relates to distillation technology field, particularly a kind of light ends unit.
Background technology
In many production processes such as rectifying, drying, all need to use light ends unit that condensable gas is caught or cooling recovery.Light ends unit comprises cold-trap and reception body, and cold-trap comprises casing, has condenser pipe in casing, and cold-producing medium is absolute ethyl alcohol or liquid nitrogen etc.The reception body is the stainless steel tank body with 2 ball valves, and 1 ball valve is connected with the lighter hydrocarbons incoming road, and 1 ball valve is connected with atmosphere.Receive the body amount of capacity and arrange according to device lighter hydrocarbons generation, 1 of operated by rotary motion for the device particular time, when estimating the very high crude oil of condensation wet goods lighter hydrocarbons content as the crude oil evaluation device, can't all be collected lighter hydrocarbons.
Summary of the invention
Purpose of the present invention just is to provide a kind of light ends unit of can be according to the lighter hydrocarbons generation and arranging flexibly.
Compared with prior art, the present invention has changed the structure of acceptor, has increased the quantity of cold-trap and reception body, can light ends unit be set flexibly according to the lighter hydrocarbons generation.
A kind of light ends unit of the present invention is comprised of a plurality of cold-traps and reception body; Receiving body and receiving uses flexible pipe to be connected in series between body; Each acceptor outer setting has condenser pipe, and the porch of condenser pipe is provided with ball valve, and it is inner that the outlet of condenser pipe is arranged on the reception body; Reception body top is provided with the stainless steel tube that ball valve is housed; Receive body and be positioned over cold-trap inside, be provided with the cold-producing medium layer between cold-trap and reception body.
Described condenser pipe is three-dimensional spiral condenser.
Described reception body is for being preferably 2～6.
Described flexible pipe is emulsion tube.
Described reception body bulk user can set as required, is preferably 2 liters.
Cold-producing medium is preferably alcohol.
Above-mentioned light ends unit mainly is applicable to various rectifier units, is specially adapted to crude oil evaluation system light ends unit.The described cold-trap refrigerant temperature of above-mentioned light ends unit scope is 0～-30 ℃.
Characteristics of the present utility model are, take to receive flexibly the body tandem plan, can arrange as required to receive body series connection use, can satisfy the device particular time, when condensate as high in lighter hydrocarbons content is estimated, guarantee that lighter hydrocarbons all reclaim.
Description of drawings
Fig. 1 is the light ends unit top view;
Fig. 2 is the side view of lighter hydrocarbons recovery dress.
Wherein: 1-lighter hydrocarbons, 2-condenser pipe, 3-cold-producing medium, 4-cold-trap, 5-reception body, 6-waste gas, 7-casing, 8-ball valve.
The specific embodiment
For content of the present invention is more likely to be clearly understood, the below according to a particular embodiment of the invention and by reference to the accompanying drawings, the present invention is further detailed explanation,
A kind of light ends unit as shown in Figure 1, 2 is comprised of a plurality of cold-traps 4 and reception body 5; Receiving body and receiving uses flexible pipe to be connected in series between body; Each acceptor outer setting has condenser pipe 2, and the porch of condenser pipe is provided with ball valve 8, and it is inner that the outlet of condenser pipe is arranged on the reception body; Reception body top is provided with the stainless steel tube that ball valve is housed; Receive body and be positioned over cold-trap inside, be provided with the cold-producing medium layer between cold-trap and reception body.
Cold-trap is in-built has absolute ethyl alcohol to be used as cold-producing medium, and cryogenic temperature is 0 ~-30 ℃.When needs are collected a large amount of lighter hydrocarbons 1, in casing 7,6 reception body series connection uses that volume is 2L; And when needs are collected the small amount lighter hydrocarbons, can reduce as required the number that receives the body series connection.Light ends unit when work, first open cold-trap, reduce the temperature to temperature required after, all ball valves are all opened, lighter hydrocarbons enter one by one each and receive body, until after the lighter hydrocarbons that produce are all collected, cut off receive separately the ball valve of body after, can obtain lighter hydrocarbons.
Light ends unit of the present invention has been attempted using on the true boiling point distillation device of Inst. of Tianjin Branch, SINOPEC, and can arrange flexibly according to the generation of lighter hydrocarbons, therefore, the design of this light ends unit has reached the purpose of expection.
