What is the Specified range for Instrument Installation verification from URS

System Description The 'Hot Detergent and Hot PUW Generation and Distribution Skid' will be used to generate and re-circulate two different cleaning fluids: i. Hot Detergent Solution: A dilute detergent solution heated to 80oC. ii. Hot PUW2 Process Water: Water heated to 80oC. The skid will consist of the equipment items outlined below together with all necessary instrumentation for control and monitoring of the process: Hot PUW2 Process Water Tank 1

Hot Detergent Solution Tank 1

Centrifugal Recirculation Pumps 4

Detergent Dosing Pump 1

Heat Exchangers 2 1.

The Detergent Tank is fed directly from the 25C PUW1 water loop.

2. The PUW1 process water is mixed with concentrated detergent and heated in a Plate and Frame heat exchanger to 80oC.

3. A duty/standby pump arrangement is used to re-circulate the hot detergent solution.

4. The hot detergent solution supply temperature is maintained by a closed loop control system, which modulates steam flow to the heat exchanger HX-211.

5. The PUW2 hot process water tank is fed directly from the 25C PUW1 water loop.

6. The PUW1 Process water is heated to 80oC in a plate and frame heat exchanger.

7. A duty/standby pump arrangement is used to re-circulate the PUW2 fluid.

8. The PUW2 hot process water supply temperature is maintained by a closed loop control system, which modulates steam flow to the heat exchanger HX-411.
