Super-capable Natural Gas Filter Element - Total Purification & Core for Gas Safety Assurance

Product Introduction

1. Adopts high-performance composite filter materials to achieve all-round efficient purification of natural gas by removing solid particles, liquid water, oil impurities, and acidic gases.

2. Innovatively designed filter element structure integrates multi-layer filtration functions, from coarse to fine filtration, to ensure natural gas quality layer by layer.

3. Suitable for filtration equipment in all links of natural gas extraction, transportation, storage, and use, serving as a key component to ensure the safe and stable operation of gas systems.

Working Process

1. Natural Gas Inflow: Impurity-laden natural gas enters the outer space of the filter element through the filter inlet.

2. Coarse Filtration: The large-pore structure layer of the outer filter element first intercepts larger solid particles in natural gas, such as sand, rust, etc.

3. Coalescence and Separation: As natural gas flows inward, the middle coalescence layer causes liquid water and oil droplets to collide and coalesce, separating and discharging them under gravity.

4. Fine Filtration and Adsorption: The preliminarily filtered natural gas enters the inner fine filtration layer, which uses special adsorbent materials to adsorb acidic gases like hydrogen sulfide and carbon dioxide, while intercepting tiny solid particles.

5. Purified Gas Discharge: Natural gas purified through three-layer filtration flows out from the central channel of the filter element and is discharged to the subsequent pipeline.

6. Condition Monitoring: A differential pressure sensor monitors the pressure difference before and after the filter element in real time. When the pressure difference exceeds the set threshold (e.g., 0.2 MPa), it indicates that the filter element needs to be replaced to maintain purification efficiency.

Product Features

FAQ

Question 1: How to select the appropriate filter element for natural gas with high H₂S content?
Answer: For natural gas with high H₂S content (e.g., >100 ppm), choose filter elements with activated carbon fiber layers and anti-corrosion membranes. The activated carbon layer enhances H₂S adsorption, while the anti-corrosion membrane resists sulfuric acid corrosion. It is recommended to replace such filter elements every 3 - 6 months to maintain adsorption efficiency.

Question 2: Can the filter element be cleaned and reused?
Answer: Most natural gas filter elements are designed for single use. While backwashing with compressed air can temporarily remove surface particles, the adsorption capacity for acidic gases (e.g., H₂S) cannot be restored. Once the filter element is saturated or the pressure difference exceeds the threshold, replace it immediately to avoid affecting gas quality and system safety.
