Polymerization-Feed Ethylene
Zenith Eclipse handles polymerization-feed ethylene enquiries against the receiving plant's approved specification. Specify purity and individual catalyst-sensitive impurities together; an overall ethylene percentage alone does not establish suitability for a polymer process.
Quality parameters
Specifications and buying requirements
Illustrative RFQ targets and purchasing requirements, subject to production or supply confirmation and buyer approval. These are not a stock COA or a universal grade. Specify the reporting basis, sampling and test method; the accepted offer defines the final quality and delivery limits. Illustrative RFQ benchmark, informed by a published high-purity pipeline specification. Limits below are examples for discussion, not a guaranteed offer or universal polymerization grade; agree current methods and plant acceptance criteria.
| Parameter | Indicative RFQ target |
|---|---|
| Ethylene purity | Example RFQ minimum: 99.92 mol%; confirm analytical method |
| Acetylene | Example maximum: 3 ppm mol; plant may require a tighter limit |
| Carbon monoxide | Example maximum: 1 ppm mol |
| Carbon dioxide | Example maximum: 3 ppm mol |
| Water | Example maximum: 5 mg/kg; mass basis, not ppm mol |
| Oxygen | Example maximum: 0.5 ppm mol |
| Total sulfur | Example maximum: 0.1 ppm mol; agree reporting convention |
| Additional impurities | Declare hydrogen, methane, ethane, C3 hydrocarbons and oxygenates; agree individual limits |
| Release documentation | Producer identity, batch or delivery COA, methods and detection limits |
Applications
Common uses
Feedstock for polyethylene production and other approved polymerization applications. The buyer's process licensor or technical team determines the acceptable impurity envelope. Buying detail: Send the full plant specification, monthly volume and receiving point. State whether limits apply at loading or delivery, and agree sampling, retained samples and an off-specification decision procedure before nomination.
Export planning
Shipping & logistics
Pipeline delivery or an approved refrigerated gas-carrier route may be evaluated according to origin and receiving infrastructure. Export enquiries require the shipment SDS, terminal acceptance and suitable cargo equipment. The quotation names the transfer point, quantity basis and Incoterm; FOB, CFR or CIF applies only where the agreed marine movement supports it.
