# Industrial Specification: Demister/Mist Eliminator

## 1. Technical Definition
A device used to remove liquid droplets or mist from gas streams in industrial processes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-10 bar differential pressure, -40°C to 200°C temperature, 0.5-10 m/s gas velocity**. Failure boundary: **15 bar differential pressure causing mesh deformation, 250°C temperature degrading polymer components, 15 m/s gas velocity causing re-entrainment**, Mechanism: **Excessive differential pressure causes plastic deformation of wire mesh elements; high temperature degrades polypropylene/polyester materials; high gas velocity exceeds droplet capture efficiency threshold causing re-entrainment**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.

- **Caution**: 

### Q: What materials are best for demisters in corrosive chemical environments?
**A**: For highly corrosive environments, polypropylene or fiberglass demisters offer excellent chemical resistance. Stainless steel (grades 304 or 316) works well for moderate conditions. Material selection depends on temperature, pressure, and specific chemicals in your process.

### Q: How does the drainage system in a mist eliminator work?
**A**: The drainage system collects liquid droplets captured by the mesh pad and channels them away from the gas stream. Proper drainage prevents re-entrainment of liquid, maintaining separation efficiency. Systems typically include collection channels, drains, and sometimes pumps for continuous removal.

### Q: What maintenance is required for industrial demister pads?
**A**: Regular inspection for fouling, corrosion, or damage is essential. Cleaning may involve washing with appropriate solvents or water blasting. Replacement intervals depend on operating conditions, but typical industrial demisters last 2-5 years with proper maintenance and monitoring of pressure drop.

## 6. Manufacturing Compliance
- ISO 14644-1:2015 (CLEANROOMS AND ASSOCIATED CONTROLLED ENVIRONMENTS)
