  • Dynawave® reverse jet scrubber

    How a reverse jet wet gas scrubber works. The DynaWave® Reverse Jet Scrubber is an open duct in which scrubbing liquid is injected, through a non-restrictive reverse jet nozzle, counter current to the dirty inlet gas. Liquid collides with down-coming gas to create the “Froth Zone,” a region of extreme turbulence with a high rate of mass transfer. The clean, water saturated gas continues through the scrubber vessel to mist removal devices. the liquid reverses ...

  • Making the invisible visible

    In FCC Units (Fluidised Catalyst Cracking Units) the atmospheric residue from the distillation is cracked to LPG, naptha and other components. This sometimes leads to “invisible” deposits inside the Riser. This article features Tracerco’s ThruVision™ scans to illustrate how the technology helped the refinery to identify these deposits at an early stage. Bayernoil operates two FCC Units to convert heavy hydrocarbons. In the FCC Unit the feed is injected ...

  • SRU solutions Dynawave® reverse jet scrubber

    Claus Sulfur Recovery Units (SRU) are found in various industries, such as refineries, natural gas processing plants, chemical plants, and coal gasification facilities. The Claus process is widely used to recover sulfur from HS containing gas streams. However, a Claus SRU can typically recover only 95 – 98% of the sulfur present. Many times, Tail Gas Treatment Units (TGTU) are installed downstream of a Claus SRU to increase the overall sulfur recovery to 99.0 – 99.9% ...
