Demister (Mesh Pad)

featuretec — Fri, 13 Feb 2015 03:51:54 +0000

In chemical process plants, outlet gases from various liquid/gas contacting devices such as evaporation towers and distillation columns often contain entrained liquids in the form of droplets. These entrained liquid droplets needs to be removed to prevent affecting the quality of gas required for the downstream processes.

The mesh type demister pad is a highly efficient solution for liquid/gas separation, using metal wire woven into a flat or round wire mesh sheet to form a separating layer to remove entrained liquids, or to recover expensive impurities from the gases.

Features:

Special design
High demisting efficiency
Simple structure
High porosity
Low pressure drop
Light weight
Easy installation and maintenance
Up to 99% efficiency for droplets larger than 1μm

Mechanism

As the fine liquid droplets entrained in the gases passes through the demister mesh pad, the droplets hit the wire meshes, adhering to the surface of the wires. As more droplets attach to the surface of the wires, the coalesced droplets increases in size and eventually falls down due to gravity, completing the separation process.

Demister Screen Pressure Drop

As demister mesh screens have low pressure drop (typically <25mmH2O), the pressure drop is usually negligible.

Applications

Petroleum refining
Petrochemical industry
Sugar industry
Chemical industry
Salt production
Power generation
Paper production
Electronics
Other various synthetic chemical industries

Demisters are commonly installed in the following equipments:

Vacuum tower
Absorber
Knock-out drums
Gas separator vessels
Compressor suction drums
Evaporators
Scrubbers
Distillation column
Concentration vessels
Dust collectors
EMI shielding products
Cushioning equipment

Sintered Metal Mesh Filter Cartridge (SM)

featuretec — Fri, 13 Feb 2015 03:41:27 +0000

Feature-Tec’s sintered metal mesh cartridge (SM) uses several layers of metal mesh sintered together to form a porous metal filter. The fine inner mesh provides an accurate filtration within a protective layer, while being supported with a support structure. Different combinations can be used depending on the application of the filter cartridge.

A plate mesh sintered filter is typically used for surface filtration, with the solid impurities trapped on the surface of the control layer. This allows the sintered metal mesh cartridge to have a high filtration precision while allowing easy backwashing.

Feature-Tec’s sintered metal mesh cartridge features excellent heat resistant, corrosion resistant and high pressure resistant properties. As such, the durable metal mesh cartridge does not deform easily, allowing repeated usage after backwashing.

Features

Excellent temperature and thermal shock resistance
High mechanical strength; impact resistant
High pressure resistance, allowing filtration of highly viscous liquids
High corrosion resistance
No shedding of metal, deformation of cartridge or side leakage occurrence
Surface filtration to ensure high filtration precision
Identical pore distribution for even filtration

Polysilicon Hot Gas Treatment Application

featuretec — Tue, 10 Feb 2015 06:29:01 +0000

Production of polycrystalline silicon (the main raw material for fabricating solar cells) developed greatly in recent years. A large number of filter separators are required in both modified Siemens method and Silane production to collect unreacted silicon powder, Chlorosilane recirculation washing liquid and filter recirculating water.

Possible Contaminants and Impurities:

Incomplete reaction of silicon powder particles
Impurities in the circulation fluid from pipelines
Impurities from the feed
Solid by-products from the chemical reaction

The listed contaminants and impurities will affect production standard, and reduce heat transfer efficiency. Efficient filtration and separation equipment not only ensures good safety production equipment technology, and also improves product yield. With the combined experience attained from many projects, Feature-Tec is able to present our filtration technology solutions.

High Temperature Exhaust Gas Purification

In the polysilicon production technology, exhaust filtration plays an important role, especially during a bad market situation to reduce costs in producing polysilicon products.

A. Waste gas/liquid separation of flue gas.

B. Reduction reaction of furnace/exhaust gas.

C. Hydrogenated furnace exhaust gas separation.

D. Silicon powder tank silicon powder filtering etc.

1. Reduction of Furnace/Exhaust Gases

After the reduction of SiCl₄, H₂ and SiHCl₃ gas via drying, H₂ and HCl can be reused. H₂ gas would need to be filtered before reuse to remove silicon powder and graphite powder. This guarantees no contaminants, the hydrogen purity, allowing a more stable and efficient hydrogenation and reduction reaction.

Problems	Requirements	Solutions
Dangerous H₂ Gas	Good sealing performance	An automatic backwash system. Removes the need to open the filter. Reduces frequency of replacing the internal parts. Prevents leakage.
Graphite powder/ silicon powder has high hardness and small particle size.	High filtration precision to prevent contamination.	Unique sintered felt metal internals. Ensures filter aperture stability. High filtration precision, up to 0.1 – 0.5 µm.
High Exhaust Temperature	High temperature resistance Removes need for cooling processes. Prevent downstream problems	Feature-Tec heat treatment process can be adopted to avoid cooling the process stream. Prevents energy wastage.

2. Waste Incineration and Removal
One of the problems in polysilicon production technology is the treatment of waste gases and liquids. Traditional spray process incurs high costs, high wastage, and creates a serious environmental problem.Solution:Feature-Tec uses dry separation technology, channeling waste gases and liquids into a combustion chamber to generate SiO₂ powders. Through separation, the dry SiO₂ powders can be recovered, resulting in great economic benefits, while at the same time solving the issue of meeting environmental standards.Technological Benefits:

1. Waste gas/liquid concentration treatment incorporates a short process and requires only simple operation.

2. Recovery of SiO₂ powders produces great economic benefits.

3. Outlet gas meets environmental protection requirements after combustion for release to the environment.

Other Polysilicon Filters

Feature-Tec filters will meet various customers’ requirements such as the improved Siemens method, silane method, chlorosilane filtration and high temperature exhaust gas separation.
