Horizontal Crossflow Scrubbers

Remove Corrosive and Noxious Fumes and Particulates

Series 760 Horizontal Crossflow Scrubbers

The HEIL Series 760 Horizontal Crossflow Scrubber is a versatile unit, specifically designed to remove mists, gases, and particulates.

The gas stream enters the scrubber horizontally, perpendicular to the packed bed. A spray header located at the inlet initiates the gas/liquid contact and provides irrigation at the front of the packed bed. Additional spray headers located at the top of the bed provide complete irrigation and wetting.

As gas passes through the packing, entrained mists and particulates impinge on both the packing and liquid droplets and are rinsed from the bed. Simultaneously, soluble gas contaminants, such as HCL, H₂S, CL₂, are absorbed. The type of gas and the desired removal efficiency determine the bed depth, irrigation rate, and chemical requirement.

Once scrubbed, the gas then passes through a mist eliminator (HEILex EB 4-Bend Mist Eliminator Blades) to remove entrained droplets and is then exhausted into atmosphere.

Series 760 Applications

HEIL Series 760 Horizontal Crossflow Scrubbers are ideally suited for service in a wide variety of applications in industries such as chemical, pulp and paper, steel and metal finishing, fertilizer, and pharmaceutical. In addition, the Series 760 Horizontal Crossflow has also been used successfully for the control of odors generated in water and wastewater treatment and laboratory exhausts.

The Series 760 Horizontal Crossflow Scrubbers are effective for the removal of corrosive and/or noxious fumes, and particulate matter (moderate loadings) 5-7 microns and larger.

Scrubbers for Higher Efficiency and Lower Costs

Principal features of the Series 760 Horizontal Crossflow Scrubber are:

  • High Efficiency – Proper sizing of the unit and selection of packing depth and irrigation rate can result in efficiencies of 99% or better. While a standard unit contains a 3 feet deep bed of packing, each unit is custom designed to the specific requirements of each individual application.
  • Compact Design – The series 760 Horizontal Crossflow Scrubber is a compact unit frequently used where space, particularly headroom, is limited. Some customers will also find its low profile more aesthetically pleasing.
  • Non-Clogging – Since the gas stream and the irrigating liquid do not directly oppose one another, as in a countercurrent scrubber, the Series 760 Horizontal Crossflow Scrubber tends not to clog, even while handling moderate particulate loads.
  • Low Operating Cost – In addition to its improved solids-handling capability, the crossflow design results in reduced static pressure losses, approximately 20% less than a comparably sized countercurrent unit. In addition, the crossflow design allows lower irrigation rates, thus both water and power consumption are reduced.
  • Versatile – The Series 760 Horizontal Crossflow Scrubber is designed to handle a wide variety of applications. The crossflow mode permits units to be easily staged in a series to achieve maximum efficiencies on the most difficult applications.
  • Extended Service Life – Corrosion resistant materials of construction, rigidon FRP (fiber reinforced polymer) is standard, providing a long service life in highly corrosive service conditions with a minimum of maintenance.

Series 760 Equipment Selection

Key factors for selecting the right crossflow scrubber for a specific application are the gas volume needing to be ventilated, type of contaminants, and the required efficiency.

HEIL engineers assist with the selection of crossflow scrubbers, as well as sizing and accessories, such as sump and fans to make a complete scrubber system. HEIL engineers also provide a specific quotation on the appropriate scrubber and/or system.
