Particle and Gas Filtration for Industrial Processes & Bag Houses
GORE Filter Bags - By Industry
The filter bags provided over 12 months of less than 6" DP service and allowed continuous production. At the design rate of 2,080 lb/hr failure occurred because of wear at the snap band cuff due to cage movement.
Solution involved installing GORE Fabric Filter Bags. Results were sixty months of continuous, problem-free service, with excellent pressure differential.
Bag life is now between 9 and 18 months, as opposed to the previous 2-4 months. Energy savings due to low DP is about $2,000/year. Emissions are virtually non-detectable with 0% opacity. Improved product recovery provided over $10,000/year of additional salable products. Less downtime and improved airflow equated to a production increase of over 10%.
High production levels and low pressure drop. Increased mill efficiency yielded considerable energy savings by producing a set tonnage in a much shorter period. The excellent cake-release characteristics enabled the collector to be operated continuously for 12 months at a maximum pressure drop of 5" w.g. The emission problem was eliminated.
Loading rates increased consistently by 50 percent. Downtime for cleaning of downstream filters was eliminated. Differential pressure was reduced to less than 0.5" H2O. Bag-replacement intervals were extended to 14 months.
Consistent 1.2" H2O differential pressure has been maintained since installation of GORE membrane filter bags despite a 9" H2O excursion due to pulse-system failure. There has been no noticeable dust on the clean side of the tube sheet since installation. The first set of bags lasted three years.

The emissions were eliminated increasing particulate capture efficiency and productivity. Filter bag life increased from 4 to 18 months.

Carbon black is produced, sized and conveyed in a powdered form. Dust collectors (baghouses) are used to efficiently collect the carbon black particulate and to control fugitive emissions. The manufacturer faced the need to increase airflow through the reactor (to increase production) and wanted to extend the service life of the filter bags in order to save costs.
A carbon black manufacturer faced the need to lower dP in the baghouse in order to increase airflow through the reactor – and, as a result, increase production. The manufacturer also wanted to extend the service life of its filter bags to lower the overall cost of ownership.
A carbon black manufacturer faced a need to maintain filtration emissions to the lowest level possible to ensure regulation compliance and increase energy production efficiency.
