Technical field
The invention belongs to petroleum gas field, be specifically liquid removing device and the liquid removing method thereof of the gas circulation loop of gas hydrates experimental loop device.
Background technology
Patent CN104634931A " gas hydrates experimental loop device ", in this experimental loop device, in order to make full use of the natural gas having neither part nor lot in reaction, the pressure in Simultaneous Stabilization loop, devise a kind of gas circulation loop.Gas hydrates experimental loop device carries out lanthanum chloride hydrate reaction as it is shown in figure 1, natural gas enters reactor from bottom under certain condition with water.The unreacted natural gas of part enters gas circulation loop from reactor top by pipeline.
Gas circulation loop includes compressor, reactor, effusion meter, pipeline, valve and corresponding temperature, pressure indicator.When the gas pressure in gas circulation loop is too high, for the pressure in stable loop, the vacuum pump of experimental loop need to be opened, by the manostat in unnecessary gas suction to system.When pressure reaches requirement of experiment, stop bleeding.In like manner, when the gas pressure in gas circulation loop is too low, the plunger displacement pump in experimental loop need to be opened, by the water suction manostat in water tank, utilize the compressibility of gas so that the pressure in loop constantly increases.When reaching experimental pressure requirement, stop compression gas.
Natural gas in gas circulation loop is unreacted natural gas in reactor, it can carry the liquid in partial reaction still in uphill process and enter pipeline, and the stable operation of follow-up equipment and whole system can be caused and have a strong impact on by the water carried, in the service life of shortening equipment, can be substantially reduced in experiment the accuracy to measuring gas flow rate simultaneously.
Summary of the invention
For the problems referred to above, the present invention provides liquid removing device and the liquid removing method thereof of a kind of gas circulation loop suitable in patent CN104634931A " gas hydrates experimental loop device ", the moisture carried is removed in the gas circulation loop of gas hydrates compound experiment device.
The liquid removing device of gas circulation loop: include liquid collecting water tank, liquid collecting water tank is connected to gas hydrates compound experiment device gas circulation loop system lowest point by input duct, and input duct is provided with liquid flowing valve；Liquid collecting water tank bottom passes through Drainage pipe connected drainage valve；Differential pressure transmitter is connected with liquid collecting water tank by connecting pipe.
The liquid removing method of the liquid removing device of gas circulation loop: in gas circulation loop system isolated liquid through input duct enter liquid collecting water tank, when liquid collect a certain amount of after, Drainage pipe discharge.
This invention is realized in removing liquid function:
The liquid removing device of gas circulation loop is arranged on the lowest point of gas circulation loop system, in order to liquid enters input duct.Owing to the density of liquid is much larger than the density of natural gas, during liquid gas coming through closed circuit, under gravity, liquid enters liquid collecting water tank through input duct and liquid flowing valve.When the liquid in liquid collecting water tank reach a certain amount of after, open draining valve, liquid is discharged via Drainage pipe and draining valve.Differential pressure transmitter is connected with liquid collecting water tank by connecting pipe, for measuring the top and the bottom pressure differential of liquid in liquid collecting water tank.
The liquid removing device of gas circulation loop provided by the invention and liquid removing method thereof, can effectively remove the moisture carried in natural gas closed circuit, thus increasing the safety and stability of experimental system, service life of extension device also improves the accuracy of this gas circulation loop system measurement data.
Accompanying drawing explanation
Fig. 1 is the structural representation of gas hydrates experimental loop device；
Fig. 2 is the structural representation of the present invention.
Detailed description of the invention
Further illustrate the present invention by the examples below.
As in figure 2 it is shown, the liquid removing device of gas circulation loop, including liquid collecting water tank 1, liquid collecting water tank 1 is connected to gas hydrates compound experiment device gas circulation loop system lowest point by input duct 5, and input duct 5 is provided with liquid flowing valve 2；By Drainage pipe 6 connected drainage valve 3 bottom liquid collecting water tank 1；Differential pressure transmitter 4 is connected with liquid collecting water tank 1 by connecting pipe 7.
For ensureing that liquid can enter liquid collecting water tank 1 smoothly, input duct 5, Drainage pipe 6 adopt the seamless steel pipe of Φ 19 × 3.Connecting pipe 7 adopts the connecting pipe of Φ 10 × 1.5, and pipe material is 0Cr18Ni9.
The effect of liquid collecting water tank 1 is to collect a certain amount of liquid and discharge it, and for saving cost, liquid collecting waterbox design becomes slim-lined construction, adopts seamless steel pipe and Plate Welding all-in-one-piece mode.Seamless steel pipe adopts the stainless steel tube of Φ 54 × 3, and length is 600mm, steel plate thickness 3mm, and steel pipe and steel plate all adopt 0Cr18Ni9 material.
4 pressure measurement differences of differential pressure transmitter are at about 6KPa (△ p=ρ g △ h, △ h=600mm), and therefore, selected range scope is at the differential pressure transmitter of 0～100KPa.Select STD924-A1A-00000-MB, SM, the 1C type differential pressure transmitter of HoneywellST3000 series
The main design parameters of this liquid removing device is:
Design temperature :-20～60 DEG C；
Design pressure: 12MPa；
Pipe material: 0Cr18Ni9

This liquid removing device is arranged on the lowest point of gas circulation loop, in order to water enters input duct under gravity.It is as follows except liquid stream journey:
(1) differential pressure transmitter 4 first returns to zero；After having returned to zero, differential pressure transmitter 4 is started working, and carries out data acquisition；
(2) when collecting liquid, first open liquid flowing valve 2, close draining valve 3.The moisture that in closed circuit, natural gas carries is entered into liquid collecting water tank 1 by input duct 5 under gravity.
(3) differential pressure transmitter 4 can measure the pressure differential of liquid collecting water tank 1 upper limit in real time, when the differential pressure measurement of differential pressure transmitter 4 reaches the higher limit set, stops collecting liquid, pass through automaton, closing liquid flowing valve 2, open draining valve 3, liquid is just discharged from liquid collecting water tank 1.
(4) after the water in liquid collecting water tank 1 is all discharged, close draining valve 3, open liquid flowing valve 2, again collect liquid.
Repeat the above steps constantly carries out liquid and collects and discharge opeing process, to constantly remove the liquid carried in gas circulation loop, thus improve the safety and stability of gas circulation loop system in gas hydrates experimental provision, extend the service life of equipment, and improve the accuracy of this gas circulation loop system measurement data.
