Description

Gases (Petroleum), Refinery, Sulfinol Process Amine Solvents, Regenerated is a regenerated amine solvent mixture specifically designed for gas purification in refinery and petrochemical operations. This product is critical for the efficient removal of acid gases like hydrogen sulfide (H₂S) and carbon dioxide (CO₂) from hydrocarbon streams, ensuring product quality and meeting environmental emission standards. It is an essential consumable for operators of Sulfinol® and similar gas sweetening units within the oil & gas, natural gas processing, and syngas production industries.

Application

• Gas Sweetening: Primary application for the selective removal of H₂S and CO₂ from natural gas, refinery fuel gas, and synthesis gas (syngas) streams.
• Sulfur Recovery Unit (SRU) Feed Gas Conditioning: Purification of acid gas feed to Claus plants to optimize sulfur recovery efficiency and catalyst life.
• Enhanced Oil Recovery (EOR): Treatment of associated gas or CO₂ streams used in EOR processes to prevent corrosion and maintain injectant quality.
• Petrochemical Feedstock Purification: Cleaning of hydrocarbon feeds for ethylene crackers or other downstream units to protect catalysts and equipment.
• Liquefied Natural Gas (LNG) Pretreatment: Essential for meeting the stringent ppm-level specifications for acid gases in LNG production trains.
• Amine Regeneration System Make-up: Used to replenish solvent inventory and maintain optimal concentration in circulating systems following thermal regeneration.

Quality Control

Our regenerated Sulfinol solvents are produced under a rigorous quality management system to ensure batch-to-batch consistency and performance reliability in your treating unit. Key parameters such as amine concentration, sulfolane content, water content, and residual heat-stable salts (HSS) are strictly monitored. A Certificate of Analysis (COA) detailing these specifications is provided with each shipment to support your operational and safety protocols.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, well-ventilated area away from incompatible materials such as strong oxidizers and acids. Storage tanks and containers should be constructed from carbon steel or other compatible materials and kept under a nitrogen blanket if possible to minimize oxidative degradation and moisture pickup.
