N-Methyl-Pyrrolidone Technical 99.8%

NMP is used to recover certain hydrocarbons generated in the processing of petrochemicals, such as the recovery of 1,3-butadiene and acetylene. It is used to absorb hydrogen sulfide from sour gas and hydrodesulfurization facilities. Due to its good solvency properties NMP is used to dissolve a wide range of polymers. It is also used as a solvent for surface treatment of textiles, resins, and metal coated plastics or as a paint stripper. It is utilized as a solvent in the commercial preparation of polyphenylene sulfide. In the pharmaceutical industry, N-methyl-2-pyrrolidone is used in the formulation for drugs by both oral and transdermal delivery routes. It is also used heavily in lithium ion battery fabrication, as a solvent for electrode preparation, though there is much effort to replace it with solvents of less environmental concern, like water.

Oil well cementing washing agents

SUMMARY

l  Use below temperature of 180?(356?, BHCT).

l  Strong permeation function which can effectively disperse and wash off the well mud cake generated during the process of well-drilling thus displacement efficiency is highly improved. 

l  Compound washing liquid featuring with non-phosphorus, non-toxic and low-foaming characteristics mainly applied as washing and spacing agents during the process of well cementation where water-based drilling fluid is applied. Good performance can be achieved as well when applied in oil-based drilling fluid.

l  In case of formulating new washing liquid by using CW110L, compatibility test should be conducted beforehand.

l  Washing liquid cannot be formulated by applying CW110L with mixing water that contains other additives or high concentration of salt. Or bad outcomes may occur due to the incompatibility.

l  Long time storage may result in muddy and blurry appearance of CW110L which is normal and has no influence on its performance.
