Product Overview

This type of polyether demulsifier is mainly based on higher fatty alcohols (dodecanol, octadecyl alcohol, etc.), propylene glycol, alkylphenol, etc. as initiators, and the molecular structure is a linear multi-block polyoxypropylene polyoxyethylene ether. It is mainly used for demulsification and dehydration of crude oil, or for improving the clarity of demulsified water in demulsifier formulations. Representative products include SP-169, BH-523B, etc.

Main technical features of the product

This type of product has good surface activity and can quickly disperse to the oil-water interface, reducing the strength of the oil-water interface film. At the same time, due to the linear structure of the molecule, it has good flocculation ability for saturated alkanes, thereby improving the interface effect of the demulsifier and the clarity of the effluent water.

Scope of application

This type of product has good flocculation ability and surface activity, and is mainly used to treat light crude oil and condensate crude oil. It can be used alone as a demulsifier, a reverse demulsifier, or as an effective component in a demulsifier formulation to enhance the oil-water interface and improve the clarity of the demulsified water.

Usage method

The oilfield chemical reagent metering device can be used for continuous dosing of the original liquid. Generally, the original liquid is added to the process in a continuous manner with a dosing concentration of 10~100mg. The optimal dosing concentration can be determined by on-site bottle test or on-site application test. If dilution is required on-site, it can be diluted with ethanol, water or a mixture of the two.

Application Cases

When the demulsifier BH-523B for Jinxian 1-1 Oilfield is injected at a concentration of 50ppm, the oil content of the injected water is maintained at 9~10mg/L, the oil content of the wastewater at the inclined plate outlet is 120-132mg/, the oil content of the wastewater at the flotation outlet is 95-116mg/L, and the oil content of the wastewater at the walnut shell outlet is 15-25mg/L. The oil content of the injected water is maintained at 9~10mg/L, and it has good synergy with the current agents, and the water content of the exported crude oil is maintained at 0.6-0.7%.

Packaging and storage

This type of product is packaged in 200L plastic barrels, PE barrels, IBC barrels, and 2000L stainless steel tanks. It should be stored in a cool, ventilated warehouse, away from fire and heat sources; avoid direct sunlight. Keep the container sealed and store it separately from oxidants. Mechanical equipment and tools that are prone to sparks are prohibited, and static electricity accumulation is prevented. When handling, load and unload gently to prevent damage to the packaging container.
Before managing, storing or using this type of related products, please carefully refer to its chemical safety data sheet (SDS) for detailed information.
