Sand Exclusion Services
Sand Filter
The Apex Petroleum Services vessel Sand Filter is designed to remove formation sand, frac proppant, and other solid particles from the well effluent. It is normally positioned upstream of the choke manifold to prevent damage to downstream equipment caused by erosion.
The Apex Petroleum Services vessel Sand Filter is designed to remove formation sand, frac proppant, and other solid particles from the well effluent. It is normally positioned upstream of the choke manifold to prevent damage to downstream equipment caused by erosion.
The Apex sand filter incorporates an ISO-sized container skid frame housing the following:
The two filter vessels are connected in parallel and can either be used independently or together.
The rigid filter screen allows a maximum differential of 1,000 psi without collapsing.
Operating temperature is -20°F ambient temperature to 350°F maximum fluid temperature. Meets requirements of NACE MR0175.
Transportation skid included.
Other sizes, configurations and pressure ratings are available to meet most applications. These ratings are guidelines only. For more information contact your local Apex representative.
Key features
- Meets applicable industry standards for added safety
- Can be third-party certified in accordance with ISO requirements
- Sized skid for ease of transportation
- Dual vessels and dual valve isolation allow for continued use while cleaning a standby vessel
- Clamp and hub assembly on vessel hatch reduces time to open and close vessels
- Pneumatic lift hoist to assist with removal and installation of filter screens
- Range of screen sizes available
- Allows increased flow rates from wells that are choked back to reduce sand production
- Avoids wellhead choke erosion and change-out frequency
- Avoids erosion and blockages in downstream process equipment (e.g., pump seals, control valves)
- Independently, the filter vessels are split into ‘duty’ and ‘standby’. The flow is passed through the duty vessel until the screen requires it to be emptied. The standby vessel is brought online, and the duty vessel is taken offline for flushing, cleaning, etc.
