    Continuous emissions monitoring for sulphuric acid production plants

    The process control of a sulphuric acid plant needs good and reliable detection of gas phase sulphur dioxide (SO2). To measure SO2 is a challenge due to the corrosive environment and high concentration of SO2. Several places in the process needs to be monitored and to transport the sample gas is difficult. A large dynamic range is needed as the SO2 concentration can vary between 15% volume and a few mg/m3. Most systems installed need a lot of maintenance, sometimes as often as every day.

    Air filtration and gas purification solutions for preservation

    The location of archives in an appropriate environment is crucial for their adequate preservation. There are many studies which identify environmental pollution as the principal problem in the conservation of historical objects. Acidic gasses such as sulphuric acid, nitrogen and carbon are the most common contaminants as these acidify archived materials, accelerating their deterioration.

  • Salt Water Disposal - Operational improvements and savings

    Adding Wilsa ElectroWaveTM technology to existing separation equipment at Salt Water Disposal Wells (SWD) or Salt Water Injection Wells (SWIW) has a profound impact on the amount of oil can be recovered without using chemicals. Additionally there is a host of operational improvements and savings that result from the Wilsa Effect. Oil free solids settle out faster for cleaner, clearer brine for injection. Cleaner brine means less injection pressure and fewer acid jobs in the formation. Pump packings last longer by reducing solids and abrasive elements from the brine. More targeted solids settling allows for less tank clean outs. All of this adds up to significant operational savings.

  • Filtration for Flue Gas Analysis and CEMS

    Three Steps of CEMS: 1st Step: Gas Sampling 2nd Step: Gas conditioning and treatment 3rd Step: Measurement/Calibration In first step, the function is to get sample gas and forward to 2nd step for treatment. During this step, it cannot block the probes and cannot result condensation of moisture. So a filter online back flushing should be equipped in this part. The filters to be used: 1, Filter is used to ensure the stability of system and reduce the maintenance 2, Filtration Grade: usually 2 or 3 micron 3, Temp. is around 0-180 deg C 4, Back flushing gas is heated, impulse flushing 5, Filter Material: Titanium Sintered, SS316L Sintered, PTFE sintered, Ceramic Membrane and so on 2nd Step Gas Treatment: #11;The coarse filters and the liquid particle filters The coarse and fine cartridge can filter the small particles in the gas and acid aerosol things to better protect the instruments. The micron can be 0.1micron, filtration rate can be up to 99.99%, two layers can be 99.9999%
