Field Operator/ Sr process Operator/ / control room operator / Lead
Oman LNG L.L.C. Sur, Oman
I worked at Oman LNG and Qalhat LNG for 9 years which is a world
class LNG producer managed by Shell. Oman LNG process was handling
an upstream dry low H2S gas. All 3 trains are equipped with common
utilities producing 10 MMTPA. The plant included Metering, Hot oil
heating system, Acid removal, Dehydration, Fractionation, Cryogenic
refrigeration using propane and MR with the aid of centrifugal and axial
driven compressors by GE frame 6 and 7 gas turbines, SCW unit, water Desalination unit,
Nitrogen, Chlorination, Condensate, LNG and LPG storage and loading terminals, Instrument
air, power generation, incinerator and fire water system.
01/02/2005 to 25/01/2008 Position Held: Lead Operator
Description: Lead the process panel operations and support the Field Sr operators in the day to day
operations. Coach the junior technicians and assist the process supervisor on managing maintenance
and work permits activities.
01/11/2003 to 01/02/2005 Position Held: SR Process Operator/ Control Room Operator
Description: To lead the field activities and be in charge of a process train where I had to handle panel
operation on line with my shift colleague.
01/09/1999 to 01/11/2003 Position Held: Field Operator
Description: To operate different units of the LNG complex including both process and utilities
were including commissioning, start ups, major shutdowns and normal operations duties.
Each train included the following units
Acid gas and CO2 Removal:
The units were initial using Sulfinol and was replaced latter on with MDEA. The main function
of the unit was the removal of CO2 up to below 5 PPM to protect the downstream MCHE
aluminum tubes form freezing and getting blocked.
Molsieve Dehydration Unit:
Three main dryer beds filed with silica based sieves where two of them go online and the third
goes through regeneration using dry heated sweet gas with a natural draft heater.
Regen gas is compressed after knocking out any water and re injected to the train inlet.
An additional mercury removal bed with a downstream filter is used to remove any mercury
traces as it reacts with Aluminum at temperatures warmer than -39 Deg C.
A series of four levels of total of 14 propane chillers are used to cool the following streams:
Inlet feed gas before the dehydration unit
The Dethaniser overhead reflux
The NGL gathered from all fractionation towers prior to reinjection to the main stream.
Mixed refrigerant cooling at the discharge of the centrifugal compressor discharge.
The propane compressor is driven by a GE frame 6 Turbine which is equipped with a helper
motor of a 7 MW capacity variable speed to assist during summer peak time.
The unit is a series of four towers a demethaniser, a deethaniser, depropaniser and a debutanizer.
The Fractionation unit utilizes Hot oil medium HTF for reboiling all light ends at the overhead of
each tower at the designed pressure and temperature.
The refrigeration consists mainly of A Main Cryogenic Heat Exchanger (MCHE) which uses two
streams of Mixed Refrigerant sprayed at the top cold bundle and bottom warm bundle cooling the
NG stream passing through the aluminum tubes coil. An expander is used with a bypass JT valve
at the heavy MR stream which recovers up to 0.8 MW of power besides reducing LNG flashes
compared to A JT valve.
The MR refrigerant loop is recompressed by two centrifugal and axial compressors driven by a
frame 7 GE single shaft gas turbine which is equipped with a helper motor as well.
The produced LNG is further cooled by passing through an expander and then to a stripper which
strips nitrogen with some methane. The end flash gas is compressed by Demag motor driven
compressor to be utilized as fuel gas.
A forced draft 4 burners with UV flame detection forced draft heater is used to heat the hot oil
loop which is used in Amine, fractionation and Fuel gas heating.
LNG and condensate Storage Tanks and Loading Arms:
120,000 M3 of LNG storage.
LNG Loading Jetty capable to handle common LNG tankers of 130,000 M3.
In addition to the floating head condensate tanks and loading jetty.
Warm wet flare, Cold dry flare, LP flare and liquid burners are used to relief any gas segregating
it based on the source and condition of relived gas.
Propane and Ethane storage:
Used to make up the Propane and the MR loop.
Sea Cooling Water System:
Six main pumps with a capacity of 16,000 M3 per day flowing via 86” pipeline.
The SCW is used to feed the desalination plants, the SCW exchangers used in the Acid removal,
Fractionation, Propane inter coolers and condensers, Mixed Refrigerant compressors intercoolers
and End flash gas inert coolers.
Vacuum based desalination to feed water for DM water used to make up the Amine/Sulfinol
solvent, top up tempered cooling water loop and fire water and drinking water make up.
Fire Fighting tank, pumps and wide spread header as well as deluge systems.
The complex uses six GE Frame 6 Gas turbines with N+1 based load principle and power
shedding to keep the main equipments in case of a blackout.
There three Air Products Cold boxes units to supply the Nitrogen header which is being used for
inerting Ebara submerged pumps, purging the loading arms, MR make up and to purge pipelines
and vessels during shutdown.
Instrument Air Compressors:
Three Motor driven compressors with a diesel driven standby unit to supply air mainly for
control valves operations.
Tempered Cooling Water:
This unit provides treated water for cooling internal loops of main rotating equipment.
Six metering Hydro cyclone runs with a sludge catcher.
Inlet PIG receiver and MEG injection provision
Custodian Quality metering Modules
Some of the special projects I have led or worked on are;
Commissioning and start up of third LNG trains
1 year assignment in commissioning an expansion project and start up (Qalhat LNG).
