Phasetreat™ Nan: advancing oil-water separation with environmental benefits

In the heart of the Middle Magdalena Basin, a Colombian energy company sought a more efficient and environmentally responsible approach to separating the crude oil and water from their wells. Partnering with Clariant Oil Services, they implemented Phasetreat Nan 19037—a proprietary aromatic solvent free demulsifier that delivers a sustainable and effective solution for oil-water separation while reducing their Scope 3 emissions for the treatment by more than 60%.

Transforming demulsification

Phasetreat Nan represents a technological breakthrough in the oil and gas industry. By replacing traditional aromatic solvent systems with an innovative water-based formulation, it not only delivers superior performance but also sets a new standard for sustainability. Key advantages include:

• Improved oil quality: Consistently meets crude oil quality targets (<0.5% BS&W, or Basic Sediment and Water – a standard measurement of the impurities in crude oil after separation).
• Enhanced water quality: Achieves a 50% reduction in oil-in-water levels and a 47% reduction in total suspended solids (TSS).
• Lower chemical usage: Enables a 10% reduction in dose rate compared to traditional products.

Delivering environmental and economic benefits

Phasetreat Nan 19037 exhibits a product carbon footprint which is 58% lower than the product it replaced in the field. Coupled with reduced dosage, this means a reduction in Scope 3 emissions of the operator of more than 60%. By eliminating aromatic solvents and lowering chemical volumes, the product supports both environmental and economic goals, offering operators a win-win solution

Real-world impact

Field trials demonstrated the far-reaching benefits of Clariant’s solution. Beyond the measurable improvements in oil and water quality, operators experienced reduced downtime and fewer third-party tank cleanouts, translating into significant cost savings and operational efficiencies.

A step forward for the oil and gas industry

Phasetreat Nan’s innovative design reflects a commitment to addressing the dual challenges of energy security and environmental responsibility. As the oil and gas industry evolves, solutions like Phasetreat Nan pave the way for more sustainable and efficient operations.

Developing innovations for the oil and gas sector is part of Clariant’s broader initiative to support a wide range of industries in the energy transition. This includes decarbonizing hard-to-abate sectors, advancing the hydrogen economy, and promoting the adoption of renewable energy sources.
