A multi-national TiO₂ producer had installed a set of standard Aramid bags. Shortly after their installation, the baghouse experienced an ongoing steady increase in pressure drop (dP).

As a result, the service life of these bags was short: just one year. These bags also suffered from problematic intermittent emissions. Learn how Gore helped solve the issues.

A multinational producer of alumina catalyst desired longer pulse jet filter bag life and steadier operation in their dryer bag house. For this trial, they installed GORE LOW DRAG Filter Bags on an identical backer.

A carbon black producer sought to improve process stability, production efficiency and bag life in their purge gas operations.
Therefore, the customer removed their incumbent filter bags and equipped the baghouse with GORE LOW DRAG Filter Bags.
For the duration of this trial, the cleaning-pulse pressure was reduced from 6 bar to 4.5 bar. All other process parameters were identical to those used for the incumbent bags.

Due to the need for longer life-time of pulse jet filter bags in jet mill baghouses, a leading talcum producer installed three different filter bags. Read the full case history to learn more about the added value of GORE LOW DRAG Filter Bags.

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.

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.

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.

The first set of GORE membrane filter bags lasted 50 months and provided more than 48 months of service at maximum production. Over a four-year period, three bag changeouts were averted, saving $43,200 in labor and $32,400 in bags.

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.
