Sulphate Removal


Sulfate RemovalCustomer Challenges

Example of scaling in piping

Mixing injected and formation water may result insulfate/barium scaling

• Limit formation of barium and strontium saltsin injection well, piping and equipment

• Production well control• Radioactive scaling or NORM• Allows anti-scalants to perform on full

effectivenessReservoir Souring

• Limit well souring at water breakthrough as NFremoves all contaminants grater than 1/1000thsof a micron

• Reduce environmental safety & health issuesby less chemical injection

• Lower level of hardness (magnesium/calciumions)


Sulfate Removal

Benefits

• One of the original Dow/Marathonmembrane suppliers – having 17 years ofexperience

• Compact system design• Single source turnkey supply

Scope of Supply• Dow SR membranes (external

technology)• SRU train with valves/instruments• Cleaning in Place (CIP) package skid• Feed booster pumps• Loose skids or module with pre-

treatment

Treatment

• Removes sulfate from seawater toprevent scaling caused bybarium/strontium in the formation water

• Nano-filtration spiral wound membranesremoves sulphate ions down to 15 ppm

• Reduces risk of souring in the reservoir
