  • Mining Emissions Effectively Monitored with Micro Pulse LiDAR Technology

    Mining operations include blasting, excavating, scraping, and sifting large amounts of dirt. These activities create dust and other emissions that are transported by air currents to surrounding areas. It is easy to say that dangerous particulate matter (PM) generated by mining should be monitored and kept to a minimum; however, it is very challenging to measure the levels of contaminants in the ...

  • Discharge Operation Steps of Industrial Chiller in Ammonia Refrigeration System

    When using air separator to discharge air, the return valve of air separator should be placed in normal open state to reduce the pressure of air separator to suction pressure, and other valves should be closed.   The mixed gas intake valve is properly opened so that the mixed gas in the refrigeration system of the industrial chiller enters the air separator.   Opening liquid ...
