Gas processing (midstream processes)

Question 1

pipeline stations

Answer 1

1. initial injection station
2. partial delivery station
3. compressor/pump station
4. block valve stations
5. final delivery station

Question 2

intial injection station

Answer 2

Known as Supply or Inlet Station; where product injected from storage, pumps or compressors

Question 3

Partial Delivery Station

Answer 3

:Known as Intermediate Stations; they allow pipeline operator to deliver part of product

Question 4

Compressor/Pump Station:

Answer 4

Compressors for gas; Pumps for oil. They move product along the pipeline

Question 5

Block Valve Stations

Answer 5

First line of protection for pipeline. The operator can isolate any segment of pipeline (like BOPs)

Question 6

Final Delivery Station:

Answer 6

Known as Outlet Stations/Terminals. Where product is distributed to customers

Question 7

Answer 7

Question 8

gas gathering

Answer 8

this is when gas is captures and piped from well head to gathering center and prepared for distribution

Question 9

gas gathering steps

Answer 9

1. Dehydration: removal of H20
2. Removal ofSulfur (H2S & other corrosives)
3. Pressure increased w/compressors (for pipeline transport)
4. Friction reduced by intermediate compressors every 10-40 km
5. Pressure& flow data transmitted to control stations for safety & quality

Question 10

LNG

Answer 10

Liquefied Natural Gas

Makes transporting gas quicker and easierthan with pipelines.

Question 11

LNG steps

Answer 11

1. Naturalgas pipeline to liquefaction plant
2. Water, CO2,Sulfur removed → pure CH4
3. Gas cooled to -162◦C to change it to liquid
4. LNG is transported in insulated, double-hulled ship and kept at -162◦C & low pressure
5. Some of the LNG changed back to gas to fuel ship
6. When the ship arrives at the regasification terminal, LNGpumped into double-walled tanks
7. It’s reheated,pipeline to customers

Question 12

LNG flow diagram

Answer 12

Question 13

FPSO stands for

Answer 13

floating production, storage, and off take facilities

Question 14

what is an FPSO?

Answer 14

FPSOs are used for preliminary processing and storage of oil.

They receive oil from nearby platforms, process them, and store them.

Later,the oil and gas are offloaded onto a tanker or transported through pipelines, but this is very costly

Do you know what processing is done? Water, oil, and gas are separated.
