Fuel Gas Coalescers

DELTA Coalescing Gas Filters: are used for the separation of oil and water particles from the natural gas stream. Coalescing Gas Filters perform the function of coalescence i.e. combination of tiny liquid droplets into the bulk liquid. Once the coalesced bulk liquid is formed, it is pulled down due to gravity into the Filter Sump. The separated liquid can be drained off either using a manual drain or continuously using an automatic drain. Delta Filters has developed a range of Gas Coalescers using high-efficiency coalescing filter elements for different applications.

Advantages :

Mention application, flow rate, op. pressure, micron rating, line size, and any other requirements.

Delta Gas Coalescing Filters

are used in the Oil and Gas, Petrochemical and Oil Refining industries. Liquid-Gas coalescers are widely used to remove water and hydrocarbon liquids. These types of equipment ensure natural gas quality and protect downstream equipment such as compressors, gas engines, metering stations, gas-fired heaters, or gas-gas purification membranes. In the Natural Gas industry, gas/liquid coalescers are used for the recovery of lube oil downstream of a compressor. Delta Gas Coalescers are employed to recover lube oil by installing a coalescer on the outlet of a compressor. Liquids from upstream of the compressor, which may include aerosol particles, entrained liquids or large volumes of liquids called “slugs" and which may be water and/or a combination of hydrocarbon liquids should be removed by a filter/coalescing vessel located upstream of the compressor. Efficiencies of gas/liquid coalescers are typically 0.5 Micron liquid particles, with efficiencies to 99.9%. Liquid-free Fuel Gas is ensured at the Outlet of Delta Coalescing Fuel Gas Filter.

Advantages :

1. What does a fuel gas coalescer actually do?
A fuel gas coalescer pulls oil and water out of a natural gas stream. Small liquid droplets merge into larger ones as the gas passes through the element, and once they’re heavy enough, gravity pulls them down into a sump, where they get drained off, either by hand or through an automatic drain.

2. How does this compare to a standard gravity separator?
Coalescers tend to cost less to install, take up far less space, and still separate liquids more effectively than gravity alone. Maintenance intervals also stretch out longer, which keeps running costs down over time.

3. What level of separation can you expect?
DELTA’s coalescers are built to catch liquid particles down to about 0.5 micron, with efficiency reaching up to 99.9%. Gas leaving the unit is effectively liquid-free.

4. Where does a coalescer go in a gas system: before or after the compressor?
Both, depending on the job. Upstream, it strips out aerosols, entrained liquids, and any liquid slugs before they can reach and damage the compressor. Downstream, it’s used to recover lube oil that’s carried over from the compressor itself.

5. What kind of facilities rely on these coalescers?
Mainly oil and gas, petrochemical, and refining operations, anywhere liquid carryover threatens downstream equipment like compressors, gas engines, metering stations, gas-fired heaters, or purification membranes.

6. What certifications back up DELTA’s coalescer build quality?
The vessels follow ASME Section VIII Division I design codes, with full radiography on every weld. Elements are pleated borosilicate glass fibre for lower pressure drop and longer service life, and every unit ships under third-party inspection, including BV, IRS, PDIL, and DNV.
