Abstract
The invention relates to a gas flow test characterization liquid, belonging to the field of test characterization liquids. The gas flow test characterization liquid comprises 1-10% by mass of pH conditioning agent. According to the formulation of the characterization liquid, the pH value can be controlled to be within the needed range; the gas flow test characterization liquid especially has an obvious effect for the special test gas; and the breakage rate of soap bubbles is greatly reduced.
Description
Technical field
The present invention relates to a kind of gas flow test and characterize liquid, belong to test and characterize the liquid field.
Background technology
It is not strong to have gas flow test sign liquid toughness now, and easily breakage, and pH is alkalescent, is not suitable for testing sour gas, and common sign liquid length service time can the generation solid adhesion.
Summary of the invention
The purpose of this invention is to provide the test of a kind of gas flow and characterize liquid, this sign liquid is applicable to the novel measuring test solution that uses under multiple test environment and the different test requests.
A kind of gas flow test characterizes liquid, and described sign liquid by mass percentage, contains 1% ~ 10% pH adjusting agent.
Gas flow test of the present invention characterizes the described pH adjusting agent of liquid and comprises acid regulator and alkaline conditioner.The character of the selective basis gas to be measured of alkaline conditioner and acid regulator determines.During the test sour gas, for guaranteeing its service time, then use acid characterization liquid, its pH adjusting agent is selected acid regulator, and control characterizes the pH of liquid 6.0 ~ 6.9; On the contrary, then use alkaline conditioner, the pH that control characterizes liquid is 8.0 ~ 8.9.
Gas flow test of the present invention characterizes the preferred described pH adjusting agent of liquid and is selected from least a of potassium citrate, sodium carbonate, sodium citrate, ammonium chloride, sodium bicarbonate, copper sulphate and iron chloride.
Gas flow of the present invention test characterize liquid further preferred described acidic ph modifier be at least a in ammonium chloride, copper sulphate and the iron chloride.
Gas flow of the present invention test characterizes the preferred described acidic ph modifier of liquid, and by mass percentage, content is 3% ~ 9%, and more preferably 4 ~ 5%, most preferably be 4.5%.
Gas flow of the present invention test characterize liquid further preferred described alkaline pH correctives be at least a in sodium carbonate, sodium bicarbonate, potassium citrate and the sodium citrate.
Gas flow of the present invention test characterizes the preferred described alkaline pH correctives of liquid, and by mass percentage, content is 5% ~ 10%, and more preferably 9 ~ 10%, most preferably be 10%.
Gas flow of the present invention test characterizes in all technical schemes of liquid all preferred described sign liquid, by mass percentage, is comprised of following component:
Gas flow test of the present invention characterizes compound or the composition that the described gas-development agent of liquid refers to produce bubble, can be surfactant-based gas-development agent, comprise ion-type and non-ionics, such as neopelex, sodium dodecylsulphonate etc., can also be commercially available various finished product washing agent, liquid detergent etc.
It is polyglycol that gas flow test of the present invention characterizes the preferred described tackifier of liquid.
Preferred technical scheme of the present invention is: described sign liquid by mass percentage, is comprised of following component: iron chloride 4.5%, distilled water 34.5%, glycerine 40%, polyglycol 10%, sodium dodecylsulphonate 11%.
Another preferred technical scheme of the present invention is: described sign liquid by mass percentage, is comprised of following component: sodium bicarbonate 10%, distilled water 40%, glycerine 30%, polyglycol 10%, neopelex 10%.
The invention has the beneficial effects as follows: adopt novel sign formula of liquid, the pH value can be controlled to be needed in the scope, particularly evident to special test gas effect, and the breakage rate of the test soap bubble also width of cloth reduces.The laboratory just can prepare, and required cost is low, economic environmental protection.
Embodiment
Following non-limiting example can make the present invention of those of ordinary skill in the art's comprehend, but does not limit the present invention in any way.
Tackifier polyglycol, glycerine, potassium citrate, sodium bicarbonate are from Tianjin Kermel Chemical Reagent Co., Ltd.; Gas-development agent is neopelex.
Embodiment 1
Adopt acid regulator, wherein acid regulator is iron chloride 4.5%, distilled water 34.5%, and glycerine 40%, tackifier polyglycol 10%, gas-development agent neopelex 11%, characterizing liquid pH is 6.2.
Table 1-sour gas test breakage rate
Can be found out at the use acid regulator for sour gas CO by table 1-sour gas test breakage rate
2Test, breakage rate significantly reduces, and stability increases.
Embodiment 2
Alkaline conditioner is sodium bicarbonate 10%, distilled water 40%, and glycerine 30%, tackifier polyglycol 10%, gas-development agent neopelex 10%, characterizing liquid pH is 8.3.
Table 2-alkaline gas test breakage rate
Can be found out at the use alkaline conditioner for alkaline gas NH by table 2-sour gas test breakage rate
3Test, breakage rate significantly reduces, and stability increases.When the test agent of targetedly test gas being selected in the different pH scopes, effect improves greatly.
