About Petroleum Chemicals
Petroleum and Petrochemical Industry Chemicals encompass a broad range of high-purity solvents, glycols, and specialty solutions required for upstream extraction, midstream transport, and downstream refining. These chemicals, including Hexane (CAS 110-54-3), Methanol (CAS 67-56-1), and Ethylene Glycol (CAS 107-21-1), serve critical roles in gas hydrate inhibition, crude oil assays, and equipment maintenance. Alliance Chemical provides specialized grades that meet strict ASTM standards for laboratory testing and field operations.
Common Applications
-
Drilling Fluid Formulation: Utilizing Ethylene Glycol to stabilize shale and prevent gas hydrate formation in high-pressure deepwater drilling environments.
-
Petroleum Laboratory Testing: Employing Hexane ACS Reagent Grade for oil-in-water analysis and hydrocarbon fingerprinting according to ASTM D6503 and D7066 methods.
-
Gas Hydrate Inhibition: Injecting 60/40 Methanol/DI Water solutions into pipelines to depress the freezing point of water and prevent blockages at low temperatures.
-
Refinery Scale Removal: Using chelating agents like Trisodium EDTA to remove mineral deposits and metal ions from refinery heat exchangers and boilers.
-
Crude Oil Demulsification: Separating water from crude oil emulsions using specialized surfactant blends to meet pipeline quality specifications (BS&W).
-
Hydrocarbon Fractionation: Utilizing precise solvent boiling points for the extraction and separation of specific petroleum distillates.
-
Industrial Degreasing: Heavy-duty cleaning of rig floors and refinery equipment using mineral spirits or high-purity d-limonene to remove stubborn crude residues.

Safety & Handling
Chemicals in the petroleum collection are primarily classified as GHS02 Flame, GHS06 Skull and Crossbones, and GHS08 Health Hazard. Handling requires strict adherence to OSHA 29 CFR 1910.1200 (HazCom) and proper NFPA 30 storage for flammable liquids to mitigate fire risks. Operators must utilize nitrile or Viton gloves, splash-resistant goggles, and work within explosion-proof environments when handling low-flashpoint solvents like Hexane (Flash Point -23°C).
Transport of these materials is governed by DOT 49 CFR regulations regarding hazardous materials shipping and manifesting. In the event of a spill, refer to EPA RCRA guidelines for the disposal of characteristic hazardous waste (e.g., D001 for flammables). First aid involves immediate flushing of eyes with water and seeking medical attention if vapors are inhaled. Always review the Safety Data Sheets before use.
