Hot gas filter elements for chemical process

The range of gas filtration equipments depends on the specific benefits of sintered porous metal elements. The filter systems are used in elevated temperature and corrosive chemical and petrochemical procedures, for gas-solid filtration of process and gases. The Monel wire mesh filters are a supreme alternative for existing filter systems where a low pressure, easy cleaning, supreme mechanical stability and chemical and heat resistance are needed.

Specific features of these filters are:

1. Nominal pressure drop: High porosity in the metal filters maintain the pressure level even at the high filtration levels as well.
2. Easy to clean- The easy structure of porous metal allows to easy cleaning through back-pulsing. These elements are fit for CIP cleaning.
3. High strength- The sintering process develops strong metallic bond and ensures good strength filter elements. Paired with a suitable internal core, the filter elements can withstand thermal shock, high pressures and frequent back pulsing.
4. Heat and corrosion resistance- Our filter elements are fit for high temperature and corrosive applications where polymeric products cannot withstand.
5. Versatile design- Filter design is fit for any type of application needs. They can be used for surface filtration or depth filtration. We make it feasible to attain the high efficiency by a cake development and also provide a dirt holding capacity for capturing the in-depth particles.
6. Filter elements- On the base of desired functionality, a suitable alloy is chosen to offer the required resistance and strength. The alloy mesh used are Alloy 601 Inconel mesh, stainless steel mesh, FeCrAl mesh and Hastelloy wire mesh.

The hot gas filters developed withstand the high temperatures and offer supreme throughput. Moreover they offer supreme back pulse efficiency without noticeable product bleed through delivering a well optimized chemical process.

The multiple layers of woven nickel wire mesh sintered into a sturdy structure. Every layer serves a special engineering purpose such as filtration, flow drainage and strength. The filter media is sintered in the porous panels that are then developed for durable and self-supporting filter tubes.

Performance of sintered hot gas filter

The gas applications design offers a filter with nominal pressure drop, providing economical system on-stream cycles. When the particles interact the filter, they are hold by the filter media. During back pulsing, the held particles are cleaned easily and filter comes back to its original condition. Heanjia develops multi-layer filter design that withstands constant back pulsing. The sintered media does not tear, hence avoids catalyst or contaminant particles from bypassing downstream.

The hot gas is usually processed in media up to 900oC in high chlorine gases. The filter tubes made from Inconel mesh have supreme metallurgical properties and mechanical strength to withstand this harsh working media.
