SAG 7133 is a high-performance silicone antifoam emulsion manufactured by Momentive. It is specifically designed to address severe foaming issues within Amine acid gas removal systems and Glycol dehydration systems in the natural gas processing, refining, and petrochemical industries.

As an industry benchmark product, it is renowned for its exceptional rapid defoaming capabilities and its stability under harsh operating conditions. If you are seeking an alternative solution, there are other products available on the market that offer comparable performance.
Below is a detailed overview of the product:
**Key Features and Benefits**
⚡ **Rapid Defoaming, High Efficiency:** Quickly breaks down existing foam, preventing flooding in absorption towers and avoiding spikes in differential pressure (Delta P). Its efficiency is typically 2–3 times that of other gas-processing antifoams, allowing for effective foam control at low dosages.
**High Stability in High-Temperature/High-Salinity Environments:** Maintains stability in the high-temperature, high-salinity, and strongly alkaline environments commonly found in amine or glycol units, ensuring it does not lose efficacy prematurely. This stability helps minimize equipment fouling and extends maintenance cycles.
🔧 **Equipment Protection, Ease of Use:** Reduces clogging and fouling in heat exchangers, thereby lowering maintenance costs. The product features low viscosity and excellent water dispersibility; it can be pumped directly or diluted with water, making it very convenient to handle.
**Key Application Areas**
**Natural Gas Purification:** Controls foaming in amine-based desulfurization and decarbonization units.
**Glycol Dehydration:** Prevents foaming within glycol regeneration systems.
**Refineries:** Used in units such as sulfur recovery plants and amine treatment systems.
**Liquefied Natural Gas (LNG):** Controls foaming during the feed gas pretreatment stage.
**Other Industries:** Can also be used for defoaming in various aqueous systems, including bio-fermentation, pesticide production, textile dyeing and printing, and metal cleaning.
🧪 **Usage Instructions and Alternatives**
**Usage Method:** It is generally recommended to add the product directly—or after dilution—to the foaming system. For high-temperature systems (>60°C), it is advisable to add the antifoam prior to heating to ensure optimal performance. The typical dosage range is between 0.1% and 0.3%; the exact dosage should be determined through field testing.
