FOHS Oil Separator Unit Fuel Filtration Systems Environmentally
Friendly
1. Fuel Oil Handling System (FOHS)
Thermo System undertakes complete Design, Engineering, Supply,
Fabrication, Installation, Erection, Testing & Commissioning of
FOHS for different type of fuels (HFO, HSD, LDO, Naphtha etc) to be
stored. Complete mechanical, electrical and engineering jobs are
covered.
Typical Fuel Oil Handling System consists of unloading hose,
decanting and transfer facilities, pumping and heating unit (if
applicable), bulk storage tank, day tank and the process utility
piping.
2. Unloading Skid
Used for unloading the fuel from tankers / wagons through hoses
A typical unloading skid consists of
Suction strainers
Pumps with drives
Instrumentation (pressure, temperature & flow)
Interconnecting piping with valves mounted on a common base frame
3. Bulk Storage Tank
Designed to API 650 and IS 803 standards to accommodate the Fuel
Oil unloaded from tankers / wagons. These can be vertical fixed /
floating roof tanks with material of construction of SS 316 / SS304
/ Carbon steel.
A typical storage tank consists of
Electrical / steam heaters
Flame and lightings arresters
Breather valves
Instrumentation (level and temperature)
Thermal insulation
4. Transfer Skid
Used for transferring the fuel from storage tanks to the day tanks
A typical transfer skid consists of
suction strainers
pumps with drives
instrumentation (pressure, termperature & flow)
interconnecting piping with valves
inline heaters on the pump discharge line mounted on a common base
frame.
5. Daily Tanks
Designed to accommodate the day’s requirement of fuel and located
near the utility point.
6. Pumping & Heating (PHF) Unit
PHF unit is used to transfer the fuel from day tanks to the utility
point i.e. boiler firing, furnace firing, engine etc at a required
pressure, temperature & flowrate.
A typical PHF unit consists of
Inline Heater.
Instrumentation (pressure, temperature, flow, viscosity etc)
Pressure regulating / control valves
The balance scope as described in the transfer skid.
7. Piping
The total process utility piping (CS/SS) - starting from unloading
point to utility point along with the necessary accessories and
instrumentation.
8. Electrical control system
This comprises of power distribution from control instruments like
RTDs, thermostats etc. for control and monitoring of various
parameters in the system.
This can be classified as follows
Control panels ( PCC/ MCC/ LCP/ PLC, Instrumentation panels)
Power, control and instrumentation casing
Cable tray, earthing etc.
