SepraLYTE™ Liquid/Gas Coalescers – Low ΔP Aerosol Removal for Hydrogen
SepraLYTE liquid/gas coalescers are designed for green hydrogen applications where removing liquid aerosols from hydrogen must be achieved with minimal pressure drop and in a compact footprint. Their polypropylene media supports broad chemical compatibility across a wide range of process conditions.
What is SepraLYTE?
SepraLYTE is a liquid/gas coalescing solution engineered to remove fine liquid aerosols such as water and electrolyte mist from hydrogen streams. It helps support downstream equipment protection and process efficiency, especially in systems with tight pressure drop limits.
Green Hydrogen Production Process: Where SepraLYTE Fits
Hydrogen exiting an electrolyzer is typically saturated with moisture and may carry fine droplets including water aerosol or electrolyte mist in alkaline systems. Separating these aerosols at the gas cleaning stage helps protect downstream compression, deoxo and drying operations while supporting overall system reliability and hydrogen purity goals.

Frequently Asked Questions
What is SepraLYTE™ used for?
SepraLYTE™ liquid/gas coalescers are designed for the green hydrogen market to remove liquid aerosols from hydrogen gas with minimal pressure drop and small vessel size.
Why does hydrogen from an electrolyzer contain aerosols?
Hydrogen generated using an electrolyzer often contains aerosols. In alkaline electrolyzers, the hydrogen gas produced can contain significant amounts of liquid electrolyte mist dispersed within the gas stream, typically consisting of about 30% potassium hydroxide solution.
Why is removing electrolyte mist important?
Electrolyte mist is highly corrosive. If not removed, it can cause corrosion and fouling in downstream equipment such as compressors and valves. This increases maintenance needs and negatively impacts hydrogen processing steps.
What types of aerosols can SepraLYTE™ remove?
SepraLYTE™ coalescers excel in separating water or electrolyte aerosols, including mist from 30% potassium hydroxide solution present in alkaline hydrogen production.
Where is SepraLYTE™ installed in the hydrogen production process?
SepraLYTE™ is used in the hydrogen gas cleaning step, after the electrolyzer and before downstream processes such as compression, deoxo units and drying systems.
Why is low pressure drop important in this application?
Hydrogen produced in atmospheric alkaline electrolysis is only slightly above atmospheric pressure, which means the available pressure drop for gas cleaning is limited. Aerosol removal must therefore be achieved with minimal differential pressure.
Is SepraLYTE™ compatible with KOH electrolyte conditions?
Yes. SepraLYTE™ uses polypropylene coalescer media selected for chemical compatibility with corrosive electrolyte aerosols such as 30% potassium hydroxide mist.
How does SepraLYTE™ support compact system design?
The compact design of SepraLYTE™ enables considerable size reduction of separation systems, which helps green hydrogen producers reduce installation and material handling requirements.
