3S-separator

JT valve

Turbo-expander - increase in of extraction of liquid

products;

- more effective temperature

decrease on same pressure

differential.

3S-separator. Combining advantages

The technology of 3S-separation is combining of simplicity of J-T valve and

effectiveness of turbo-expander – natural gas effective dewpointing without

turbo-expanders and chillers

- space-saving and easy to include

into the existing production

scheme;

- low capital costs and operating

expenses;

- absence of moving parts;

- no regular maintenance.
