What Is Ethylene Production?
Ethylene production uses steam cracking to convert hydrocarbon feedstocks into ethylene and other petrochemical products.
Filtration and separation technologies help manage contaminants throughout the process, supporting equipment protection, product quality and downstream operations.
Ethylene Production at a Glance
| Feedstocks | Process | Challenges | Objectives |
|---|---|---|---|
| Ethane, propane, naphtha and gas oil | Steam cracking and separation | Liquids, solids and contaminants | Equipment protection and process reliability |

Ethylene Production Hot Section
During steam cracking, feedstocks such as ethane, propane and liquid hydrocarbons are heated at high temperatures to produce ethylene and related products. After cracking, the process stream is cooled, separated and purified through downstream operations.
How Coalescer Technology Supports Ethylene Production
Coalescer technologies can help support ethylene production operations by:
- Reducing free liquids in pygas streams
- Removing corrosion by-products where required
- Reducing particulate and hydrocarbon carryover
- Supporting longer process run times

| Protect Furnace Feed Streams | Reduce particulate and liquid contaminants in furnace feedstocks before they enter critical process equipment. | Improved reliability and reduced fouling. |
| Improve Burner Performance | Remove contaminants that contribute to burner tip deposits and reduced furnace efficiency. | Improved performance and lower maintenance. |
Ethylene Production Hot Process Facts
- Usage: As a basic building block in the manufacture of ethylene glycol, polyethylene, polypropylene, polystyrene, polyester resin, polyvinyl chloride, etc.
- Form of final product: Gas with low boiling point.
- Feedstocks: Ethane, propane, ethane/propane, naphtha, gas oil.
- How it’s made: By cracking of gas or liquid feeds in high temperature furnaces, followed by quenching the cracked gas and obtaining various products by fractionation.
