Description
Technical field
The utility model relates in a kind of Device in Gas the profit ash content to be measured and uses condensing unit, belongs to Device in Gas pick-up unit technical field.
Background technology
The content of the oil in the methane gas, water, ash is an important indicator estimating the methane gas product quality; And whether oil in the Device in Gas that produces in the industrial, water, ash content measured value is accurate, recycles for the calculating of commercial plant material balance, heat Balance Calculation, device improvement, Device in Gas upgrading processing, Device in Gas to have important directive significance.Composition more complicated in the methane gas; The concentration of oil, water, ash and inequality in the local gas; Oil content assay method, liquid water content assay method and dust determination method in the report gas are arranged at present, but also do not have a kind of method can accurately, directly measure oil, water, the ash content in the gas simultaneously.
Determination method for oil content in the gas of having reported mainly is to take solvent absorption, sorbing material absorption process or condensation enrichment absorption process to collect oil in the gas, utilizes the oil content in the measurement gas such as infrared spectrophotometry, ultraviolet spectrophotometry, gravimetric method, turbidimetry, vapor-phase chromatography, gas detector method again.
Wherein, Solvent absorption is to utilize the oil in the gas can well be dissolved in the character in the normal hexane; In venting process; Be adsorbed onto again in the absorbent cotton with the oil of normal hexane with carried away by air movement, with oil in normal hexane flushing, desorption absorption bottle and the absorbent cotton, with the normal hexane constant volume in the 100mL volumetric flask.According to reported in literature, normal hexane is no absorption peak at the 260nm place, be good solvent, and oil has maximum absorption band herein, and its absorbance size is directly proportional with oil content, meets langbobier law, that is: A=KC.
The sorbing material absorption process is: a certain amount of fibrous material of filling (absorbent cotton, spun glass, mekralon etc.), quantitative filter paper, spun glass film or other sorbing material in stopple coupon (like activated charcoal etc.); During sampling; Let measurement of gas pass through stopple coupon, and write down the sample volume of gas with wet test meter with certain flow velocity.
Condensation enrichment absorption process is the glass spiral cold-finger to be immersed in the refrigerant such as liquid nitrogen, with measurement of gas with certain flow through condenser pipe, the oil in the gas is condensed in the spiral pipe, again with solvent with its wash-out.
In addition, also can be with reference to the rock gas methods of light hydrocarbon recovery, comprising absorption method, oil-absorption process and condensation separation method.Absorption method is to utilize solid adsorbent (like activated charcoal, silica gel and zeyssatite etc.) different to various hydro carbons adsorption capacities, thereby makes the method that heavy constituent separate with light constituent in the rock gas.Oil-absorption process (like horse traction (Mhear) method) be based on each component in the rock gas in absorbing oil dissolubility difference and make method light, that the heavy hydrocarbon component is able to separate.Absorb general naphtha, kerosene or the diesel oil of adopting of oil, its relative molecular weight is 100-200.According to the difference of absorption temperature, oil-absorption process can be divided into normal temperature, middle gentle low temperature oil-absorption process.
Because above the whole bag of tricks lacks the means of oil standard material in the preparation gas, the accuracy of the whole bag of tricks, precision and repeatable relatively poor, and above method is not suitable for the mensuration of the oil content in the moisture gas.
The content of measuring water in the gas has two class methods, and one type is instrumental method, comprises with cooling minute surface condensation hygrometer measuring the gas water dew point and directly measuring liquid water content in the rock gas with electrolytic liquid water content analyser; Another kind of is chemical method, comprises karl Fischer method, phosphorus pentoxide absorption process and colourimetry etc.But above two class methods not energy measurement contain the industrial gasses of large quantity of moisture, and can not measure oil content and the ash content in the gas simultaneously, and range of application is narrower.
