Detect molecular sieve breakthrough before moisture or mercury reaches downstream equipment.
The Welker Mole Sieve Probe is designed to sample natural gas from molecular sieve adsorption beds upstream of moisture and mercury analyzers in natural gas processing and LNG trains. Mounted directly to a mating flange on a dehydration unit or mercury removal unit, the probe extends across the inner diameter of the bed to monitor the gas stream across the full width of the molecular sieve. By sending samples to a downstream analyzer, the Mole Sieve Probe helps operators detect rising water or mercury levels, identify molecular sieve breakthrough, plan regeneration, and protect downstream equipment from costly damage and process shutdowns.
Natural Gas Processing
In molecular sieve adsorption beds upstream of moisture and/or mercury analyzers to help detect breakthrough and protect downstream equipment.
LNG Trains
In dehydration units or mercury removal units where molecular sieve performance must be monitored before contaminants can damage downstream process equipment.
Multi-Level Bed Monitoring
Multiple probes can be installed at different levels in a DHU or MRU to monitor molecular sieve deactivation across the height of the bed.
Resources
316/316L Stainless Steel Construction
Provides durable, corrosion-resistant construction for improved equipment longevity in natural gas processing and LNG applications.
Electropolished and Dursan®-Coated Wetted Parts
Helps minimize corrosion, absorption, adsorption, and chemical reactivity in the sample pathway.
NACE Compliance
Supports use in applicable sour gas or corrosive service environments.
Johnson Screen Vee-Wire® Filter Element Probe Overlay
Helps prevent particulates and molecular sieve material from entering the sample pathway while maintaining reliable sample flow.
Full-Width Bed Sampling
Extends across the inner diameter of the adsorption bed to provide a broader view of moisture or mercury breakthrough conditions.
Manual or Actuated Closure Valves
Provides configuration flexibility for operating preferences, maintenance access, and system automation needs.
