JMG Series Large Flow Natural Gas Coalescer Cartridge For Long-Distance Trunk Pipeline Dewatering

Midstream pipeline operators often face a costly trouble: standard small-size coalescer cartridge cannot handle ultra-high gas throughput of trunk lines, the service life of ordinary coalescer filter is sharply shortened under heavy liquid load, bringing frequent unplanned shutdown losses. LEFILTER JMG series large-flow coalescer filter cartridge is tailor-made for high-yield natural gas stations, adopting widened multi-layer gradient coalescer filter element, the liquid storage capacity increased by 60% compared with conventional coalescer cartridge filter. As core dewatering component of heavy-duty gas filter system, JMG gas filter element works with JFG gas filter cartridge as front solid interception and ST separator cartridge as secondary liquid barrier, forming three-stage solid-liquid purification train for raw natural gas filter. All JMG series are mature mass-production models in our catalog, you can view full gas filtration parts via gas filter element category, supporting industrial RO membrane and UF membrane module displayed on Water Filter Element.

Working Principle Of JMG Coalescer Cartridge

High-volume raw natural gas flows from outer layer to inner core of JMG coalescer filter cartridge. The outer thick fiber layer intercepts pipeline rust and hard solid particles; wide-pleated coalescer filter element captures massive emulsified water mist, merging tiny droplets into large gravity-settling beads. After coalescence treatment, dry gas flows through central pipe and enters ST separator filter element to eliminate secondary liquid entrainment. The optimized fiber layout of this coalescer cartridge filter maintains ultra-low pressure drop under full load, effectively reducing long-term power consumption of pipeline compressors, which cannot be achieved by narrow-pleat ordinary coalescer filter.
