NATURAL GAS FILTERS

Delta Natural Gas Filters are high-efficiency filters for filtering rust, dust, condensates, and other liquids from the Natural Gas stream. We have a wide range of sizes from 1/2" NB to 16" NB. Filter vessels are designed as per ASME Code to serve pressures till 300 Bar. DELTA Natural Gas Filters have been exported worldwide. We offer Filters for Dry Gas Filtration as well as Coalescing Gas Filtration. Low 0.07 Bar Pressure Drop and long life, ASME Coded Natural Gas Filter Housings. Natural Gas is a clean source of energy being widely used for Power Generation, Transportation, and Heating. Gas Exploration, Transmission, and Compression lead to contamination during various activities. Focussed on serving the Oil & Gas Sector since our establishment in 1994, Delta Filters has developed a range of Natural Gas Filtration solutions.

Compressed Natural Gas (CNG) Filters and Duplex Fuel Gas Filters are also manufactured by Delta Filters. Natural Gas is a convenient fuel source in terms of transmission and combustion. However, it gets laden with impurities like oil, dust, rust and condensates during various stages of drilling, compression, and transmission. For effective combustion and protection of metering instrumentation, it is imperative to install a high-efficiency Natural Gas Filter in the Gas Line. Delta Filters is involved in the Design, Manufacture & Supply of a wide range of Natural Gas Filters for various applications including City Gas Distribution, metering skids, MRS, DRS & Servo Gas (Instrumentation). Delta Filters has developed efficient designs to serve various Natural Gas Filtration requirements. Our filters used pleated filter elements which allow a high flow rate within compact filter housings. Filter Vessels are designed as per ASME Sec VIII Div 1 Code. Welding is carried out by Qualified Welders as per SGS approved WPS / PQR following ASME Sec IX. NDT Procedures are followed as per ASME Sec V.

We manufacture and supply highly reliable Natural Gas Filter Cartridges. Pleated borosilicate glass-fiber is employed as the filter media which increases filtration area 4x times compared to competitors. End result for the customer is lower pressure drop, long life between replacement, and lower maintenance cost. We manufacture a wide array of Fuel Gas Filter Elements for Gas Compressors, Gas Dispensers, Metering Skids, and Gas powered Engines. DELTA Gas Filter Elements employ German Borosilicate Glass Fibre filter media which has a large void volume for the highest dirt holding capacity. This leads to low energy loss and long filter element life.

Frequently Asked Questions (FAQs)

1. What is a Natural Gas Filter?
A Natural Gas Filter is a filtration device designed to remove contaminants such as dust, rust, pipe scale, condensates, oil, and moisture from natural gas streams. It helps protect downstream equipment and ensures cleaner, more efficient gas flow.

2. Why are Natural Gas Filters important?
Natural Gas Filters prevent contaminants from reaching sensitive equipment such as compressors, flow meters, regulators, gas engines, turbines, and control valves. Effective filtration improves equipment reliability, reduces maintenance costs, and enhances operational efficiency.

3. What contaminants can Natural Gas Filters remove?
Natural Gas Filters can remove solid particles including dust, rust, pipe scale, and other particulates. Coalescing filter designs can also remove liquid contaminants such as water, condensates, and lubricating oil carryover from gas systems.

4. What is the difference between a particulate gas filter and a coalescing gas filter?
A particulate gas filter removes solid contaminants from the gas stream, while a coalescing gas filter removes both fine liquid aerosols and solid particles. Coalescing filters combine small liquid droplets into larger droplets that can be separated and drained from the system.

5. Which industries use Natural Gas Filters?
Natural Gas Filters are widely used in city gas distribution networks, gas transmission lines, compressor stations, metering skids, MRS and DRS stations, power generation facilities, gas engines, gas turbines, and petrochemical plants.

6. What filtration efficiency is available for Natural Gas Filters?
Natural Gas Filters are available with various filtration ratings, including 5 micron, 3 micron, 1 micron, and finer filtration options depending on process requirements and equipment protection needs.

7. What are pleated borosilicate glass fibre filter elements?
Pleated borosilicate glass fibre filter elements provide a larger filtration surface area compared to conventional filter media. This design helps achieve lower pressure drop, higher dirt-holding capacity, longer service life, and improved filtration performance.

8. What pressure ratings are available for Natural Gas Filters?
Natural Gas Filters can be designed for a wide range of operating pressures depending on the application. Delta Filters manufactures ASME-coded filter vessels capable of handling pressures up to 300 Bar for demanding gas filtration services.

9. What is a Duplex Natural Gas Filter?
A Duplex Natural Gas Filter consists of two filter housings connected in parallel, allowing one filter to operate while the other undergoes maintenance. This arrangement ensures uninterrupted gas flow and continuous operation in critical applications.

10. How do I select the right Natural Gas Filter?
Key selection parameters include gas flow rate, operating pressure, operating temperature, line size, filtration efficiency, contaminant type, and required connection standards. Providing these details helps ensure the correct filter sizing and performance.

11. Are Natural Gas Filter vessels manufactured according to international standards?
Yes. High-quality Natural Gas Filter vessels are commonly designed and manufactured in accordance with ASME pressure vessel codes, with qualified welding procedures, testing, and inspection processes to ensure safety and reliability.

12. How often should Natural Gas Filter elements be replaced?
Filter element replacement frequency depends on gas quality, contamination levels, operating conditions, and pressure drop across the filter. Monitoring differential pressure is the most effective way to determine when maintenance or element replacement is required.
