Portable Emissions Analyzers for Mining Applications
Application Note # IA-14-0302
When extracting and refining valuable geological materials from the earth (eg. limestone, aluminum oxide, gold), a variety of industrial combustion processes are required. The machinery used in these processes such as industrial engines, boilers, and smelters can emit highly toxic gases that are harmful to the environment and to human life. Using a portable emissions analyzer enables mining personnel to ensure personal and environmental safety, while optimizing the performance of the mining operation.
At any given mining site, significant levels of CO, CO2, NOx (NO + NO2), SO2, H2S, & CxHy hydrocarbons can be emitted into the air causing serious harm to the environment. Each year, emissions regulations are becoming more stringent in order to limit the creation of excess greenhouse gases. In additional to the typical emissions that are generated by the many combustion sources present at mines, the materials being mined (eg. gold) can cause the emissions to be particularly dirty and corrosive. Portable emissions analyzers provide accurate measurements of important emissions parameters and can allow for easy reporting to regulatory agencies.
Personal Health & Safety
High levels of carbon monoxide in ambient air can cause headaches, fatigue, nausea, and even death in extreme cases. NOx, especially NO2, can cause serious respiratory issues, and unburned combustible hydrocarbons can be a safety hazard especially at higher levels that can be ignited. Regular emissions testing with a portable emissions analyzer will alert mining personnel of potentially dangerous conditions.
Measuring the O2 and CO levels in the exhaust or flue gas from generator engines or boilers, for example, can provide an indication of how lean or rich an engine is burning or how efficiently a boiler is running. The combustion analyses can be utilized for tuning of the engines and boilers for optimal combustion performance. Optimizing engine and boiler performance will save both time and money.
E Instruments’ E8500 Plus is a complete portable emissions analyzer that can measure up to 9 gases including O2, CO, CO2, NOx (NO + NO2), SO2, H2S, & CxHy hydrocarbons and comes standard with a built-in thermoelectric chiller for superior flue gas conditioning and real-time data-logging software. High temperature gas sampling probes with a sintered filter can be provided for many mining processes that produce flue gases with very high temperatures and large amounts of dust, particulates, and ash.
