Metering Petrochemical Additive Injection Fluids

Titan Enterprises has published an online article** that reviews the evolving role of different flow meter technologies in measuring injection additives in petrochemical processes.
 
For the successful transportation and refining of crude oils a whole raft of additives are required. These vary from simple surfactants through to complex blended scale and corrosion inhibitors. These chemicals are injected in small quantities at high pressure and are critical to the whole refining process. Consequently, careful monitoring of their addition to any process is essential, and often this is best done using petrochemical flow meters. Petrochemical additive injection fluids vary in both viscosity and density, and any petrochemical flow meter installed into a plant should be able to cope with a wide range of physical and chemical properties.

 
The article discusses how positive displacement, rotary piston, spur and oval gear, thermal, Coriolis and ultrasonic flowmeter technologies have been used for petrochemical applications.  The author concludes that each one of above petrochemical flow meter technologies discussed has its own strengths and weaknesses (which are detailed in the article) and a choice will largely depend on financial constraints and personal experience.
