Thermal conductivity detectors (TCD) are essential for the measurement of non-infrared-active gases such as hydrogen (H2), nitrogen (N2), helium (He) and all the other noble gases. Simple and inexpensive measurement of other gases such as Carbon dioxide (CO2) and methane (CH4) can be realized.CONTACT US FOR MORE INFORMATION
COMBINED HEAT AND POWER UNIT OR BLOCK-TYPE THERMAL POWER STATIONThe power units use the energy of fuel in two ways.
The fuel which is burned in a motor, as the mechanical energy, is used to generate electricity. The heat is used for heating purposes.
The result is high efficiency, 80-90% of the fuels primary energy are used.
In cogeneration units the plug end of the fuel energy is used particularly efficiently. The fuel is burned in a motor, the mechanical energy is used to generate electricity. At the same time the by-product heat is also used for heating purposes.
As fuel, wood pellets are very common. The wood pellets As a result, 80-90% of the fuels primary energy are used.
One of our customers used among other things a renewable raw material, namely wood pellets, as fuel for its cogeneration plants.
These are converted into a first combustion with too little oxygen.
The resulting gas mixture contains, hydrogen (H2) and carbon monoxide (CO), which is in the next step used as fuel for power generation engines.
The monitoring of the hydrogen (H2) content of the fuel gas is realized with AGIMAS FTC-110 with T90 times of less than a second.
ELEMENTAL ANALYSERSorganic and non-organic solids
In elementary analyzers are composed of organic and non-organic solids.After weighing the sample is digested with furnaces up to 3000 ° C and then the resulting gas mixture with different measuring principles is analyzed.Thus, for example, the carbon content of the sample as a carbon dioxide (CO2) in the non-dispersive infrared analyzer (NDIR) is measured.After removal of interfering gases such as carbon dioxide and water vapor thermal conductivity detectors are for the determination of hydrogen (H2) and nitrogen (N2) is used.In the determination of H2 is used as the carrier gas N2 or argon. The determination of nitrogen is accomplished in a helium stream.In this application, it is particularly for the low detection limit of TCD220. This is the measurement of H2 in N2 at less than 10 ppm.CONTACT US FOR MORE INFORMATION
MEASUREMENT IN HUMIDITY OR CORROSIVE SAMPLE GASESThe main challenge of the measurement with the thermal conductivity detectors in humidity gases is to protect the sensor from burning-out. After passing below the dew point, the gas becomes a condensate and the drops cause the detector to burn out. AGIMAS engineers solved this problem. We placed a sintered frit before the sensor element as a protection. The pore sizes are in the micrometer range, which is impermeable to liquids. The molecules of the sample gas can pass almost without resistance. We use only very high quality materials for the gas paths, which leads to long life of the gas analyzer in aggressive environment.
HELIUM MEASUREMENT IN AIRSHIPScustomized Helium / humidity measurement
The movement of airships is more stable in comparison to airplanes, helicopters and drones. It has less shocks during the flight and is ideal for HD Photos or geo-research. The airships are filled with helium. This gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. The helium diffuses in the envelope over time. It is very important to check the purity of helium at regular intervals. AGIMAS TCD 220 is an ideal monitoring tool for this application, due its small dimensions and customized Helium / humidity measurement.CONTACT US FOR MORE INFORMATION
HYDROGEN FED MONITORINGAn application in the chemical industry is monitoring hydrogen supply. At this line, several producers and consumers of hydrogen gas are connected. The hydrogen producers fed has to have a certain purity over 99% In case of determination, the purity fell below the needed 99.9 Vol.%, the affected line had to be closed as soon as possible not to determinate the complete fed. In this case the gas analyzer had to detect the change of purity very quickly, for rapid closure of the fed. The ideal solution for the rapid response solution is the AGIMAS TCD220
LABORATORY- AND PILOT PLANTSmall dimensions
Only in exceptional cases technical equipment can be used for new production of the chemical industry on the basis of literature data and computational simulation. The usual way of scaling up via laboratory testing and the subsequent construction of a pilot plant for large-scale technical plant. Due to its small size, AGIMAS gas analyzers can be easily integrated into small systems of FTC 110. The rapid time of response and the flexibility of TCD220 helps to reduce costs, save time, and improve plant efficiency.CONTACT US FOR MORE INFORMATION
LANDFILL & BIOGAS ANALYZERSThe water produced during the fermentation biogas consists of 90% methane (CH4) and Carbon dioxide (CO2), But also contains a variety of other gases such as CO, O2, H2 and H2S. For analysis of biogas, the infrared-active gases such as CH4, CO2 and CO are determined by the NDIR method, Oxygen (O2) and Hydrogen sulfide (H2S) are measured with electrochemical sensors. For the determination of Hydrogen (H2), TCD220 is used.
MULTI GAS MODEPrecise linearization for binary gas mixtures
Many binary gas mixtures required measurement of different gases. Usually you need specialized equipment with a cascaded gas analyzer system. These systems are big and expensive. With AGIMAS TCD 300 you get a single instrument for a reasonable price which has the possibility to measure 16 binary gas mixtures sequentially with one device.CONTACT US FOR MORE INFORMATION
RECOVERY OF USED HELIUMThe recovery of used helium is particularly useful for meeting the environmental certification requirements under DIN EN ISO 14001 and for saving resources. The monitoring of the purity of helium in this application is very important. Our devices meet the necessary claims for the measurement.
STEEL-MAKING AND NON-FERROUS METAL INDUSTRYhydrogen or a hydrogen / nitrogen gas mixture
The components are often heat treated after molding in order to achieve desirable mechanical properties. The treatment of the component is under a pure hydrogen atmosphere or a hydrogen / nitrogen gas mixture. The reducing power of the hydrogen plays an important role here. The additional effect is the cleaning of the surface through the hydrogen. In addition, the hydrogen by its high thermal conductivity enhances, the efficiency of thermal processing plants. AGIMAS gas analyzer TCD220 monitors the filling of the oven with hydrogen. After the treatment process of the workpiece, the oven has to be free of hydrogen while it is opening. The hydrogen residue can leak and an explosive gas mixture would be the result. The cleaning of the oven from hydrogen before opening is realized through purging. The monitoring of the purging is also realized with the same gas analyzer.CONTACT US FOR MORE INFORMATION
HYDROGEN MEASUREMENT IN LOW PRESSUREThe thermal conductivity measurement is relatively insensitive to pressure variations.This is because two effects are canceling each other out. On the one hand decrease of pressure increase in the number of particles which transport the heat energy.Second effect is the reduction of the mean free path of the particles.
The heat is no longer transported as effective.When pressure changes in the negative pressure region, the micromechanical Thermal conductivity sensors are influenced very strongly by pressure.
This especially applies to light gases such as hydrogen (H2) and helium (He).Therefore, dependent on the particular gas concentration, a correction is necessary.In combination with pressure gauge and measured pressure, the thermal conductivity measurement is automatically adjusted.Thus, the pressure dependence of pure nitrogen is reduced to a few parts per million (ppm).
But also for gas mixtures having a higher pressure dependency as e.g. 50 vol.% H2 in N2, the pressure dependency is effectively reduced. In the pressure range of 300 to 2000 mbar absolute, in this case the influence of pressure is on the measurement signal only at less than 0,05Vol.%.
