Eliminate Unwanted Product
The RS-1/2 can be incorporated into any sampling or slipstream process unit. It is designed to reinject the product used by the unit, eliminating unwanted product in the station sump system. The RS-1/2 Recovery/Re-Injection System consists of a 15 gallon stainless steel tank, 4 level stainless steel float system, 2HP or 3HP explosion proof motor, reduction gear box, positive displacement pump, and a program-mable logic controller (PLC). The RS-1/2 Recovery/Re-Injection Sys-tem has 3 modes of operation.
With the selector switch in the NORMAL position, product enters the recovery tank from the flasher as it is running. The product will rise in the tank until it reaches the 9.4 gallon level float switch (LS1, high lev-el). The motor / pump will start injecting product into the pipeline until the product level decreases below the lowest level float switch. If the Process Unit should stop, then the RS-1/2 can be interconnected to stop also. When the unit resumes operation, the RS-1/2 will start inject-ing again once the product level has risen above the LS2 float level switch. The tank will be pumped empty in approximately 5 minutes.
In the fast cycle mode, (selector switch in the FAST position) the pump will start when product level reaches the 3.7 gallon lowest level float switch. The tank will be pumped empty in approximately 2 minutes.
In the manual cycle mode, (selector switch in the MANUAL position) the pump unit will run as long as the product level is above the lowest level float switch.
The RS-1/2 Recovery System has alarm outputs to alert station personnel of an abnormal or malfunction condition and PLC protection to prevent tank overflow or pump / motor damage.
