Chemistry and Manufacture
Innospec´s drag reducer additives are a new and patented technology. IDR-4181P & IDR-6181C are drag reducing agents in a suspension of high molecular weight poly alpha olefins polymer into vegetable oil. Except for trace quantities, they do not contain any metal, ammonia, sulphur, chlorine or water. IDR-4181P & IDR-6181C contain neither dispersant nor any surface-active material. Their chemical structure is entirely organic composed of C, H and O atoms only.
Applications and dosages
Once injected into hydrocarbon fluids, the polymers contained in IDR-4181P & IDR-6181C will solvate and extend into long linear molecules. These specific structures reduce the formation of micro-turbulence, thus reducing overall pressure losses in the treated pipeline. The polymer remains active as long as it remains long and linear. Once broken by a high pressure pump for instance, it will lose its efficiency. Since the drag reducing agents do not contain any water nor any dispersant, IDR-6181C are designed to be used to treat Crude oils and IDR-4181P for use in refined products. The recommended dosage rates are:
5 to 30 ppm IDR-6181C for crude oil applications
2 to 10 ppm IDR-4181P for finished product pipelines.
