Introducing Our High-Performance Bag Filter Nets: The Ideal Solution for Filtration Needs

Ethylene Oxide Production Process

Ethylene Glycol

Due to the high precision requirements of the slicing and fiber industries, fine filtration of raw materials is essential.
Any minor impurities in the raw material will affect product quality and reduce market value.

Ethylene Oxide

Can serve as a deicing agent
Filtration systems prevent nozzle clogging in deicing equipment
Both ethylene glycol and ethylene oxide are hazardous chemicals; manufacturers must minimize operator exposure. High-capacity filters extend service life, reduce media replacement frequency, and decrease exposure opportunities. Additionally, fewer media changes effectively lower hazardous waste disposal costs.

Circulating water filtration

Process Overview

Water washing primarily removes residual degreasers, phosphating agents, and contaminants from workpiece surfaces. This step can be performed via spray or immersion methods. The counter-current washing process employs a single immersion wash as a supplement to the initial spray wash, with a secondary immersion wash supplementing the second spray wash. Washing solution is filtered and reused; bag filters are recommended.

Problem Description

Automotive finishing plants' spray booths are major water consumers, with pre-treatment wastewater accounting for over 80% of total booth drainage. Consequently, effective filtration to meet recycling standards is critical for reducing pure water usage and wastewater discharge, thereby achieving energy conservation and consumption reduction.

Product Advantages

Compatible with high-performance magnetic rods, installed within bag or cartridge filter housings to capture magnetic iron filings, extending filter bag or cartridge lifespan;
Suitable for both heavy contamination and high-cleanliness requirements;
Low initial investment cost with no equipment modification required—direct replacement of filter bags;
POP filter bags significantly enhance filtration efficiency by 85%, increase dirt-holding capacity, extend service life threefold compared to standard bags, reduce replacement frequency, and rapidly lower consumable and labor costs.

Ethylene Compressor & Compressor Protection

Ethylene Compressor and Molecular Sieve System

Despite the use of demisters, the molecular sieve beds in ethylene production have a service life of less than three years. After compression, hydrocarbons in the ethylene concentrate into fine mist, which is difficult for demisters to separate. This fine mist, along with compressor lubricating oil, degrades the performance and lifespan of the molecular sieves.

The lifespan of molecular sieve resin depends on the number of regeneration cycles. During each cycle, elevated temperatures and reduced pressure cause hydrocarbons to evaporate from the sieves, simultaneously inducing molecular sieve cracking. The resulting wear from fissures necessitates costly replacement of the sieve material.

Frequent regeneration cycles
Reduce adsorption capacity
Premature molecular sieve replacement
High energy costs
Recommended Solution

Install a gas-liquid coalescer downstream of the demister in ethylene production to remove aerosols containing hydrocarbons as small as 1µm and aqueous aerosols.
