n-Propyl alcohol (NPA)
Colorless liquid with a pungent odor.
n-Propyl alcohol (NPA), also known as 1-propanol, is a clear and colorless liquid with a pungent odor. It is a primary alcohol that is soluble in water, ethanol, and other organic solvents. NPA is commonly used as a solvent, intermediate, and chemical reagent in various industries, including pharmaceuticals, cosmetics, coatings, and energy.
Energy Sector
n-Propyl alcohol (NPA) can be used as a component of drilling fluids to help prevent formation damage and stabilize borehole walls. It can also be used to reduce the risk of differential sticking, which occurs when the drill string becomes stuck in the formation due to differential pressure. Additionally, NPA can be used to improve the lubricity of drilling fluids, which can help to reduce the wear and tear on drilling equipment and improve drilling efficiency. Moreover, NPA can also be used to reduce the surface tension of drilling fluids, which can enhance their ability to penetrate and displace water in the formation, thereby improving well productivity.
Water Treatment
n-Propyl alcohol (NPA) can be used in water treatment as a coagulant aid to enhance the performance of coagulants such as alum and ferric chloride. It can also be used as a flocculant aid to improve the settling and dewatering of suspended solids in wastewater treatment plants. Additionally, NPA can be used as a disinfection booster to enhance the effectiveness of chlorine and other disinfectants in killing harmful microorganisms in water. NPA can also be used as a solvent for extracting and purifying organic compounds in water treatment processes such as activated carbon adsorption and membrane filtration.
Pulp & Paper
In the pulp and paper industry, n-Propyl alcohol (NPA) is used as a solvent and surface-active agent in the production of paper and paperboard. It is used to dissolve resins, pigments, and other additives in the coating formulations for paper and paperboard. NPA can also be used as a defoaming agent to prevent the formation of foam during the papermaking process. Additionally, NPA can be used as a cleaning agent to remove pitch and other contaminants from paper machine clothing and other equipment. Finally, NPA can be used as a dispersant and wetting agent to improve the dispersion and wetting of fillers and other additives in papermaking formulations.
