Dry Gas Filters

Particulate filtration for gas processing and pipeline service.

Dry Gas Filters equipment
Equipment overview

Engineered for the application.

Dry gas filters remove solid contaminants from gas streams. Pars Technic supplies filter vessels configured for the required flow, operating conditions, element selection, and maintenance requirements.

Engineering scope

  • Filter vessels for gas service
  • Element selection aligned with the filtration duty
  • Access closures for inspection and maintenance
  • Project-specific connection and support arrangements

How it works

Cartridges load, the gauge climbs.

Gas enters above the tube sheet and passes through pleated cartridges from the outside in; the solids stay on the media. A differential-pressure gauge piped across the tube sheet shows how loaded they are, and tells the operator when to change them through the quick-opening closure.

Differential-pressure gauge needle: what loading doesShell 762 mm OD, cartridges 152 × 914 mm, class 600 closureIllustrative values. Clean pleated cartridges typically show about 0.07 bar (1 psi) at design flow and are changed out at about 1.0 bar (15 psi); in between, the model takes ΔP to grow exponentially with the solids held and in proportion to flow. The operating pressure of 50 bar g is an example: the closure can be opened only after the vessel is isolated and vented to zero.
