Flow Switches for Oil/Gas Refinery Water Treatment

From Fluid Components Intl. (FCI)
 

 
The water used in the the cooling units, desalter units, and other water from throughout the plant creates a large amount of wastewater with VOC's that must be treated before it is recycled or discharged. There are many different types and choices of systems, chemicals, filters, membranes, screens, etc., that can be used in refinery wastewater treatment. They all, however, have one thing in common: liquid flow switches are necessary to monitor and control the flow of water and chemical additives throughout the wastewater treatment system. Flow switches are used at multiple points in water applications that range from pump protection to valve leak detection. In selecting a flow switch for refinery water applications, the first step is choosing the appropriate flow switch technology. There are numerous flow switch sensing technologies available from multiple manufacturers. They all have their advantages and disadvantages, including the required reliability, process media (clean liquids, dirty liquids, slurries) and your application's requirements. Thermal flow switches, for example, are a popular choice in refinery water applications because they offer exceptional reliability with no moving parts and a mean time between failure (MTBF) rating of 190 years
