General Checklist the Essential Steps and precautions for Pre-start and Starting up the Centrifugal Pumps . # What’s the things you Should be attention physically? # General centrifugal pump start up procedure:- Before pump start-up you must perform these tasks:- *01.  Open the suction valve , do priming by venting all the air inside the suction line by opening any vent or even the PG vent till liquid coming out then close , now you confirm no air inside the system to reduce the chances of pump getting cavitation *02.   Open any re-circulation  or cooling lines. *03.   Fully close or partially open the discharge valve, depending on system conditions. *04.   Start the driver. *05.   Slowly open the discharge valve until the pump reaches the desired flow. *06.   Check the pressure gauge to ensure that the pump quickly reaches the correct discharge pressure. *07.   If the pump fail to reach the correct pre...

## There’re 4 Liquefaction Process Technologies for LNG Production:- #01.  C3MR APCI (Air Products) Process.   #02.  Cascade (ConocoPhillips) Process: * 1- The raw gas is first treated to remove (CO2), (H2S) and other sulfur compounds, (H2O), organometallic mercury compounds, particulates, and other contaminates before it is routed to the liquefaction section of the plant. *2- The treated gas is then chilled and condensed to approximately -162°C in successively colder heat exchanges , using pure propane (or propylene), ethylene, and methane as refrigerants. *3- The refrigerant circuits are designed with 2 drivers/compressors for each refrigerant which provides a wide range of turn down  capacity and a high degree of availability. For the propane cycle core-in-kettle type exchanges  are used. Brazed aluminium plate-fin exchanges  (cold boxes) are applied mainly in the ethylene and methane cycles. All the cooling, with except...
