HYPOCHLORITE GENERATOR PACKAGE UNIT

RFQ Details

Skid mounted sodium Hypochlorite Generation Package (with 100% standby)

The system shall be sized to continuously dose active chlorine into seawater flow of 400 gpm from firewater pumps at 2 ppm concentration.

Skid Inlet Water Pressure: 105 to 150 PSIG
Design Temperature: 120 F

The system shall consist of complete electrolytic sodium hypochlorite generators from seawater on a once through basis. Each unit shall have hypochlorite production turndown capability from 10% to 100% of specified design capacity
Due to limited space, system shall be of compact construction. (Approx. 2m x 5m)

The system shall include:

- Electrolytic cell assembly.
- Transformer/ Rectifier Unit, dry type
transformer, air cooled, thyristor controlled
rectifier, suitable for 480VAC/3PH/60Hz
power feed.

System shall be capable of diluting Hydrogen generated to safe levels and venting it to a safe location.

- Main Control Panel; PLC based; hosed in 316 stainless steel IP56 (NEMA 4X) enclosure, designed to provide necessary pushbuttons, run lights, alarms, indicators, relays and control circuitry as required for safe operation of the system; including HMI touch screen interface, with both RS-485 and Modbus TCP/IP interface network cards for communication with DCS.

- All required process piping, valves, pressure regulators, safety valves, etc. Materials shall be suitable for offshore application, preferably CPVC SCH. 80.

- Shall be supplied with booster pumps and flow regulators for the inlet seawater when required.

- Inlet strainers shall be supplied. One automatic backwash and one manual. (D-070/071).

- Supplied with pumps to inject the hypochlorite into a firewater stream with a pressure of 1137 kPa (165 psig).

- Assembly of the units on structural steel skids, with APCS-1D (SAES-H-004) coating suitable for corrosive, hot, humid, salt laden offshore environment, lifting lug and grounding lugs.
