Applications of Hot Gas Filter

Chemical and Petrochemical Industry

In refineries and FCC field, Filson hot gas filter can be used as FCC 3rd and 4th stage separators. It is designed to withstand high temperature and pressure, and achieves catalyst fine emission reduce. With special materials, it performs well in FCC flue gas environment.

Cement Industry

Many VOCs are regarded as hazardous air pollutants, and most are related to cement and lime industries. By adding a nano-catalyst on Filson hot gas filter, our product can effectively remove PM, NOx, and other particles at the same time. And performs well when the temperature is up.

Glass Melting Furnaces

Filson hot gas filter is rigid with excellent resistance to thermal and thermal shock. When combining with sorbent injection, it can remove other pollutants in glass melting, such as mercury, SOx, acid and NOx. With high efficiency of pollutant removal, our product is popular in this field.

Waste Treatment and Incineration

Through sintering process, Filson hot gas filter has fine filtration accuracy, down to 3 mg/m3, including PM 2.5. It can work normally under high temperature between 900°C to 1260°C. Besides, it also has large filter surface, increasing reaction time.

Biomass Furnaces

Most biomass has low calorific value (CV) but burns fast, which pose a huge impact on emissions and fuel consumption. Filson hot gas filter has excellent high-temperature resistance and meet chemical requirements to achieve continuous filtration.

Catalyst recovery filtration

Filson hot gas filter can effectively block catalyst fines in any harsh conditions. With back-pulse function, our product does its best in catalyst recovery while minimizes energy. It reduces catalyst loss, which saves customer maintain costs. In FCC/CCR/S-ZORB, it is popular choice.

What is the Different Between Candle Filter and Filter Bag?

What is the Different Between Candle Filter and Filter Bag?

First, they are different with shapes. Candle filter is rigid tube, while filter bag is made as bags.

Second, the material and process are different. Candle filter is fabricated with metal powers and ceramic powders, such as titanium, stainless steel, Monel, etc. After sintering processing, they are robust and can withstand higher temperature than filter bags, which porous ceramic filter up to 1260°C.

Bag filter can withstand temperature ranges from 190°C to 200°C due to materials, such as aramid, PPS. The strength lies in high tensile strength while low tensile elongation.

You can choose the right hot gas filter according to your needs and specifications we list, or you can tell us your unique requirement for customized service.

Why Hot Gas Filter Can be Used in Catalyst Recovery Filtration?

Why Hot Gas Filter Can be Used in Catalyst Recovery Filtration

For economic and environmental perspectives, the recovery of catalyst is important and can be recycled for many times. But inevitably, catalyst can also lose its active.

For example, in crude oil refining and petrochemical fields, hot gas filter is used as catalyst hoppers in fluid catalytic cracking (FCC) and continuous catalytic reforming (CCR). Because hot gas filter can effectively remove catalyst fine from vent gas streams at high temperature while minimizes pollutions.

With lower costs of maintain and operating, and high-level filtration efficiency, hot gas filter is your best choice.
