Accumulated Acid Flow Control

The accumulated acid control loop uses a valve that controls the hydrofluoric acid level in the acid accumulator. Spent hydrofluoric acid is constantly circulating from the acid accumulator to the rerun column. An upset in this valve could cause a leakage of hydrofluoric acid, which would be a major environmental and health risk. 

With such a highly acidic environment a 1” or 2” Fisher EZ control valve, supplied by Spartan, is ideal for this application. With good rangeability and control these valves have body’s made of monel or steel to withstand harsh conditions.

Gain superior control and accurate mass flow and density measurement by utilizing Spartans Accumulated Acid Flow Control solution. 

Fisher
Fisher EZ valves are used for throttling or on-off control of a wide variety of liquids and gases. The single-port, globe-style body design offers quick-change trim and a post-guided, unbalanced valve plug. The EZ valve is used in chemical or hydrocarbon processing applications or wherever control of non-lubricating, viscous, or other hard-to-handle fluids is required.
The FIELDVUE DVC6200 is a digital valve controller capable of operating using 4-20 mA, HART, Fieldbus, or Profibus communication protocols. The basis of its operation is the conversion of a control signal into a pneumatic output controlling valve position.
