ADVANCED MEASUREMENT OF MERCURY IN FLUE GASES Extractive gas analyzers Sensor Intelligence.

PROVEN MEASUREMENT TECHNOLOGY, IDEAL FOR REFERENCE PURPOSES Reliably measuring mercury in flue gases is difficult and places a great deal of demand on measuring technology. The innovative MERCEM300Z mercury gas analyzer from SICK is able to take reliable measurements in situations where other measuring systems have had to give up. Challenges of measuring mercury Continuously measuring mercury in flue gases presents a number of particular challenges for measuring systems. Firstly, the Hg concentrations to be detected are smaller than other flue gas components by a factor of 1,000. Limit values...

Reliable measuring technology thanks to a combination of conversion and photometers With the MERCEM300Z gas analyzer, SICK has set a new standard when it comes to analyzing mercury. No mercury leaks, no chemicals used – instead, we apply hot measuring technology, which has been proven over many years. Measuring without moving parts – minimal maintenance The production of the measuring gas is based on the low-maintenance ejector principle. What's more, taking the measurement itself does not require any moving parts. MERCEM300Z: The mercury gas analyzer characterized by its very low maintenance...

MERCEM300Z Indoor For measurements in air-conditioned rooms at temperatures from +5 to +35 °C For measurements outdoors at temperatures from –20 to +50 °C Compact standard design for the installation in air-conditioned rooms. Possible to arrange additional cabinets on the left-hand side. • Ambient temperature: +5 °C ... +35 °C. Optimized industrial design for measurements in harsh ambient conditions near to where the sample is taken – with integrated air conditioning. • Ambient temperature: –20 °C ... +50 °C.

MERCEM300Z – proven industrial design High-temperature converter Optical unit Automatic test gas generator (option) Hg conversion in high-temperature converter Owing to the principles involved, mercury can only be measured in its elemental state. Therefore, it is essential to convert all mercury compounds to their elemental states before actually determining the Hg concentration. And this is where the key advantages of the MERCEM300Z really lie: The conversion is carried out using a purely thermal method, simply by using high temperatures of about 1,000 °C – no chemicals or non-durable catalyst...

MERCEM300Z – PREDESTINED FOR FLUE GAS MEASURING Mercury is attracting more and more attention globally when it comes to monitoring emissions. Plant operators are faced with increasingly large challenges thanks to new annual limits in Europe and new legislation on measuring mercury in cement plants and coal-fired power plants in the USA. In many cases, the permitted limits for flue gases are already below 10 µg/Nm3. Power plants, incineration plants, or cement kilns, which use fossil fuels or household goods as a fuel must all take responsibility. The fuel used, e.g., lignite or bituminous coal...

Plant safety If high concentrations of mercury are present in the process over an extended period of time, this can cause the flue gas washer to become overloaded with mercury and can ultimately lead to the entire plant becoming contaminated. In the worst case scenario, this could bring the whole plant to a standstill. This can be avoided if high concentrations of mercury are detected in the raw gas using an accurate measurement at an early stage and the appropriate countermeasures are implemented. The requirements for continuous mercury measuring systems in raw gas are significantly higher in...
