01 Product
Pyrolysis gasoline / Pygas supply overview
ALGHAF MARINE FZCO supplies bulk pyrolysis gasoline, commonly known as Pygas, for qualified petrochemical processors, aromatics producers and traders under FOB and CIF terms.
Pygas is an aromatics-rich liquid stream generated in steam-cracking operations and is commercially evaluated according to its cargo-specific composition, stability and downstream processing suitability.
Non-sanctioned origin Pygas is available for selected cargo programs, with final origin, assay, loading point and logistics structure confirmed transaction by transaction.
What is pyrolysis gasoline (Pygas)?
Pyrolysis gasoline, or Pygas, is a gasoline-range hydrocarbon stream produced as part of steam-cracker operations.
It typically contains a significant aromatic fraction together with olefins, diolefins, styrenic compounds and other hydrocarbons whose proportions vary according to cracker feedstock and operating conditions.
Because Pygas composition varies materially between sources and production campaigns, commercial evaluation should be based on the applicable cargo assay rather than a universal specification.
Pygas should not be confused with finished motor gasoline or FCC gasoline.
Raw Pygas & processing suitability
Raw Pygas can contain reactive unsaturated compounds and may have limited stability without further processing.
Its commercial suitability therefore depends not only on aromatics content but also on diolefins, olefins, styrenic compounds, sulfur, contaminants, gum-forming tendency and other assay parameters relevant to the buyer's processing route.
For buyers operating hydrotreating, hydrogenation or BTX recovery units, the critical purchasing specification should reflect the actual downstream process requirements.
Pygas hydrotreating & hydrogenation
Pyrolysis gasoline is commonly processed through selective hydrogenation and hydrotreating before downstream use.
A typical processing sequence may involve a first hydrogenation stage targeting diolefins, styrenic compounds and selected olefins, followed by further treatment for remaining olefins and sulfur where required by the downstream process.
The required severity and processing route depend on the feed assay and intended final product slate.
ALGHAF MARINE FZCO does not represent untreated Pygas as hydrotreated or hydrogenated product unless that processing state is expressly confirmed for the contracted cargo.
Pygas for BTX & aromatics recovery
One of the principal petrochemical uses of Pygas is as an aromatics-rich feedstock for recovery of benzene, toluene and xylenes (BTX).
Depending on the processing configuration, an appropriate Pygas fraction may be hydrogenated, hydrotreated, fractionated and routed to an aromatics extraction unit.
The commercial value of a Pygas cargo for BTX recovery therefore depends on its aromatic composition, boiling-range distribution, contaminants and the buyer's unit configuration.
02 Grades
Why Pygas assay consistency matters
Pygas is highly assay-sensitive because changes in cracker feedstock and operating conditions can materially affect composition and downstream processing behavior.
For a processor, parcel consistency can influence reactor loading, hydrogen consumption, fouling tendency, product yield and aromatics recovery performance.
For this reason, qualification should focus on the parameters critical to the buyer's unit rather than relying only on a generic product name.
Pygas vs FCC gasoline
Pygas and FCC gasoline are different refinery or petrochemical streams.
Pygas is associated with steam-cracker operations, while FCC gasoline originates from fluid catalytic cracking refinery units.
Their composition, olefin and aromatic profiles, sulfur behavior, processing requirements and commercial applications differ.
They should not be treated as interchangeable products without full assay comparison.
Pygas vs reformate
Pygas and reformate can both contain valuable aromatic components, but they originate from different processing routes and have different composition and stability characteristics.
Reformate is produced through catalytic reforming of naphtha and is commonly used as a high-octane gasoline blendstock or aromatics feedstock.
Pygas originates from steam cracking and can contain higher levels of reactive unsaturated compounds that may require hydrogenation or hydrotreating before downstream aromatics processing.
03 Origin
Non-sanctioned origin Pygas
ALGHAF MARINE FZCO can offer non-sanctioned origin pyrolysis gasoline for selected petrochemical processing programs and approved destinations.
Origin and loading location are transaction-specific and depend on cargo assay, allocation, destination and shipment window.
Final origin and loading point are confirmed in the applicable commercial offer, SPA and cargo documentation.
Loading location does not by itself determine product origin.
