Description
Technical field
The utility model relates to commercial measurement device field, more particularly, the utility model relates under a kind of negative pressure state the determinator of oil, water and ash content in the Device in Gas and uses this device to carry out under the negative pressure state assay method of oil, water and ash content in the Device in Gas.
Background technology
Oil in the methane gas, water, ash content are important indicators estimating the methane gas product quality.At energy manufacture field, the most of negative pressure that adopts of Device in Gas induction system is pumped.Can accurately measure oil, water, ash content in the Device in Gas under the negative pressure state, have important directive significance for the calculating of commercial plant material balance, heat Balance Calculation, device improvement, Device in Gas upgrading processing, Device in Gas recycling.Composition more complicated in the methane gas under the negative pressure state, oil, water, ash concentration and inequality in the local gas have oil content assay method, liquid water content assay method and dust determination method in the gas under the report negative pressure state at present.But also do not have a kind of method accurately, directly to measure the oil in the gas, water, ash content under the negative pressure state simultaneously.
Determination method for oil content under the negative pressure state of prior art report in the gas mainly is to take solvent absorption, sorbing material absorption process or condensation enrichment absorption process to collect oil in the gas.Oil content in the measurement gas such as recycling infrared spectrophotometry, ultraviolet spectrophotometry, gravimetric method, turbidimetry, vapor-phase chromatography, gas detector method.Solvent absorbs: the oil in the gas can well be dissolved in the normal hexane, in venting process, be adsorbed onto again in the absorbent cotton with the air-flow entrained oil with normal hexane, with oil in normal hexane flushing, desorption absorption bottle and the absorbent cotton, use the normal hexane constant volume in the 100mL volumetric flask.According to reported in literature, normal hexane be good solvent, and oil has maximum absorption band herein at the no absorption peak in 260nm place, and its absorbance size is directly proportional with oil content, meets langbobier law, that is: A=KC.Sorbing material absorbs: a certain amount of fibrous material of filling (absorbent cotton, glass fibre, mekralon etc.), quantitative filter paper, glass fibre film or other sorbing material in stopple coupon (as activated charcoal etc.), during sampling, allow measurement gas pass through stopple coupon with certain flow velocity, and write down the sample volume of gas with wet test meter.The condensation enrichment absorbs: the glass spiral cold-finger is immersed in the refrigerant such as liquid nitrogen, with measure gas with certain flow by 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 (as 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, as 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 separated.Absorb general naphtha, kerosene or the diesel oil of adopting of oil, its relative molecular weight is 100 ~ 200.According to the difference that absorbs temperature, oil-absorption process can be divided into normal temperature, middle gentle low temperature oil-absorption process; Because above-mentioned 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 said method is not suitable for the mensuration of the oil content in the moisture gas under the negative pressure state; The assay method of liquid water content has two classes in the gas, and a class 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 these two class methods can not be measured the industrial gasses that contain large quantity of moisture, and can not finish oil content and ash content in the tested gas simultaneously, and range of application is narrower.
