In the industrial field, good flare design is vital to allow maximum destruction of “waste gases”. Good design ensures minimum harmful emissions to the atmosphere. At the same time, efficient design and operation will reduce operating costs.
The waste gases, sent to the flare for destruction, can come from different points of the process. Therefore, a correct monitoring of its calorific value is vital. To ensure maximum efficiency in its combustion. It will also make it possible to determine whether the gas can be used as a fuel on its own, or whether it will require enrichment with an auxiliary fuel.
Micro-combustion calorimeters provide a direct measurement of the Calorific Power. The sample gas, pre-mixed with a combustible gas, is incinerated in the equipment. This causes a temperature variation, which is proportional to the Calorific Power. In this way the analyzer provides a direct measurement of the Calorific Power.
Our CalorVal analyzer from the American company Control Instruments belongs to this category of analyzers. Robust and reliable, its design and manufacture have been tested in numerous installations. This analyzer is capable of withstanding the harsh environmental conditions required in this type of application. It is therefore the optimal solution for the control of the heating power in torches.
Simple installation, fast response
The CalorVal is a lightweight and compact analyzer. Suitable for direct mounting in the field, next to the measuring point. It does not require mounting in the analyzer house. Long heated sample transport lines, sample pumps and conditioning systems can therefore be dispensed with. Response time is therefore reduced (less than 4 seconds), allowing quick adjustment of the torch auxiliary fuel flow when needed.
Minimal maintenance
Its particular design, with a fully heated measuring chamber and sampling system, avoids possible condensation of water vapor and less volatile heavy hydrocarbons. Otherwise, they could be lost, causing inaccuracies in the measurement. In addition, the presence of condensate could cause maintenance problems. This feature, together with its simple but efficient Venturi suction sampling system, with no pump or moving parts, makes it possible to reduce the maintenance of the equipment to the minimum possible.
Direct measurement, with universal response
Control Instruments’ proprietary technology applied in the CalorVal allows the measurement of the Calorific Value of a wide variety of gases. Although the instrument has been calibrated for a particular gas, it provides excellent cross-calibration for many other gases, with minimal measurement errors as sample composition varies.
The CalorVal provides a uniform response for a wide range of combustible gases and vapors. Including heavy hydrocarbons, carbon monoxide and hydrogen, as well as many other compounds commonly found in waste gases.
