3A takes up water while limiting uptake of larger olefins at the crystal pore. Protection grades address challenging inlet exposure.
A few ppm of water in cracked gas can cause hydrate or ice formation in the cold section. Trace oxygenates, CO₂ or sulfur compounds can push product off spec or affect sensitive Ziegler–Natta and metallocene catalysts.
JALON makes molecular sieves and adsorbents to remove these impurities, with material selection matched to your feed, outlet targets and planned cycle.

Across different plant configurations, cracked gas, product streams and polymer feed each have their own impurity and outlet limits.
Residual water in cracked gas upstream of the cold section
Keep moisture below the cold-section limit to avoid hydrates or ice.

Residual water, oxygenates, CO₂ or sulfur compounds
Meet the individual impurity limits in the product specification.
The treatment material follows the measured contaminant; drying alone does not establish oxygenate purity.
Trace water, oxygenates, CO₂ or sulfur entering the reactor
Meet the catalyst supplier’s limits before impurities affect activity or polymer quality.
A saleable monomer stream may still need further purification before polymerization.
Moisture, oxygenates, CO₂ and sulfur compounds place different demands on an olefin purification bed. JALON offers molecular sieves, activated alumina and duty-specific grades to address these removal needs, from selective drying to catalyst-feed polishing.

Static H₂O and CO₂ capacities and crush strength show how a material performs in defined tests. A real olefin bed can still reach its outlet limit before the planned changeover. What matters is usable working capacity under your feed—and which controlled impurity approaches its limit first.
Average feed analyses can miss water spikes, oxygenate swings or liquid carryover. At the actual flow, temperature and pressure, these events increase the load on the bed.
Competing impurities do not move through a bed at the same rate. One can reach its outlet limit while other capacity remains unused.
Incomplete regeneration leaves less working capacity for the next run. Particle size and pressure drop also constrain the bed; excessive heat can promote deposits in olefin service.

Documented batch results, with a 200 g reference sample retained for three years.
Its approximately 3À crystal openings admit water while excluding the larger olefin molecules. This limits crystal-pore uptake of valuable ethylene or propylene. A larger-pore material such as 4A has a different co-adsorption profile, so its suitability must be checked for the actual stream.
