Get A QuoteThe only certain way to guard against fires and explosions is to use continuous flammable gas monitoring. Background. Non-condensable gases, usually referred to as Total Reduced Sulfur compounds (TRS) or Dilute Vent Gases, are by-products of the kraft pulp process. These gases, mostly sulfurous, are extremely malodorous and flammable.
Get A QuoteSome Kraft pulp mills control total reduced sulfur compounds (TRS) by accumulating and burning these gases in the lime-kiln, or black liquor recovery boiler. The combustion process converts the TRS to SO 2, some of which is collected in the kiln's gas cleaning system. Many mills use electrostatic precipitators for particulate control.
Get A QuoteA boiler could be used for part of the cooling, but usually water sprays are used to cool the flue gas. The rapid temperature change at this stage can cause corrosive and thermal expansion problems. SO2 scrubber. Passing the cooled flue gas through a wet scrubber will …
