DK-SA 830 Gas-Solid Separator

Overview

The DK-SA 830 Gas-Solid Separator is widely used in on-shore condensate gas fields at natural gas wellheads and pilot testing sites, as well as in off-shore condensate gas pla?orm wellheads. The primary purpose of this separator is to remove coarse sand particles from the natural gas produced by gas wells through a swirling motion, thereby protect subsequent processing equipment from damage. Key components of the Gas-Solid Separator include a swirl barrel, a sand settling tank, and supporting process valves. It is also equipped with a safety venting device to ensure safe operation.

Principle

The DK-SA 830 Gas-Solid Separator operates on the principles of centrifugal sedimentation and density differences. When the fluid enters the separator tangentially at a certain pressure, it generates intense rotational motion. Due to the differences in fluid density, the forces of centrifugal force, centripetal buoyancy, and fluid drag act differently on the components. This results in the lower-density gas rising and being discharged through the separator outlet, while the higher-density sand is expelled from the sand discharge outlet at the bottom of the device, achieving the goal of sand removal.

Features

l   Flexible, Diverse, Customizable

l   Utilizes advanced swirl technology for superior sand removal efficiency.

l   Small size with high processing capacity, saving on- site space.

l   The sand settling tank is designed for ultra-high pressure to ensure safe operation.

l   Easy to operate and transport, reliable and safe.

l   Capable of accommodating 10~150% fluctuations in natural gas production.

l   Can work uninterrupted during operation, avoiding the need to shut down wells for sand removal.

l   Prevents secondary contamination of oil quality associated with other sand removal methods, maintaining high sand removal efficiency.

Installation

ü   The Gas-Solid Separator should be installed on the main pipeline of the gas supply network and secured to a base. A bypass should be added between the separator outlet and the sand settling tank.

ü   When installing the Gas-Solid Separator, ensure there is sufficient maintenance space around it.

ü   During normal operation, the plug valve between the swirl barrel and the sand settling tank must be opened, while the sand discharge valve and bypass valve should be closed.

ü   For sand removal, periodically discharge sand based on the sand content in the gas and the pressure indicated on the sand settling tank pressure gauge. First, close the plug valve between the sand settling tank and the Gas-Solid Separator, then open the pressure relief valve. When the pressure in the sand settling tank reaches zero MPa, open the sand discharge valve. The sand removal process should not affect the normal operation of the system.

ü   After sand removal is complete, first close the sand discharge valve and the pressure relief valve. Then, open the bypass valve for the sand settling tank. Once the pressure in the sand settling tank stabilizes with that in the swirl barrel, open the plug valve and close the bypass valve.
