Sand Filtration Units

Airpac Bukom’s rental fleet of 5,000psig, 10,000psig and15,000psig sand filtration units improve well analysis during testing operations through the effective removal ofsand and other solids from the well effluent.

The sand filter consists of two vertical vessels, each vesselholding one inner filter assembly. The two filtration pods arecontrolled individually allowing for either single or dual potoperation. Normally, one vessel is in use, in order to facilitate cleaning of the other.

The unit is skid mounted and complete with inlet and outletmanifolding, double gate valves on the downstream side andconnections to register differential pressure acrossfilters. Each sand filter is supplied with an extensive sparespackage and fully equipped tool box.

Features and Benefits

> Modular and rugged filter design> Standard 200 micron filter cartridge supplied> Annular flow and sand storage> Safe & quick cleaning features> Vertically positioned gate valves (to avoid gate

obstruction)> Fitted with back up valves> No post-frac clean up required, production starts

immediately through the facilities

Options

> A range of micron screen sizes are available onrequest.

Filtration System

The stainless steel mesh filter consists of one element,which is mounted concentrically. Opposite to the laser cutscreen, the mesh screen filter has more slots. The filterassembly element can be altered in an early manufacturingstage, if required by the application.

Advantages:

> Minimum mesh size 50 Micron> Filter collapse pressure <100barg> Maximum OD 14¼ inch> Gas flow capacity

5,000psig up to 20 MM scf/d10,000psig up to 35 MM scf/d15,000psig up to 50 MM scf/d

> Liquid flow capacity up to 5,000 Bpd

Flow capacity is dependant on filter element mesh size, viscosity and the amount of pollution. The inner filterelements are designed to stop sand/debris transport,without obstructing liquid and or gas flow through the unit.Gas velocities across the filter elements are greatly reduced,minimising actual filter wear and increasing its life span.

Cleaning

The 5,000psig and 10,000psig units have a series of high pressure water injection nozzles positioned on the outervessel diameter, to facilitate sand removal between vesseland filter element. The sand/water mixture exits the vesselthrough 2" flow points, positioned on the bottom side of thevessel. Cleaning time per vessel approx. 15 minutes.

On the 15,000psig units cleaning is effected by using the21/16" manual choke to remove the sediment out of the vessel. The filters are emptied by removing the screens outof the top of the vessels, utilising the air operated hoist andafter which the sand can be removed and the screeninspected.

Filter element removal is not required during operations. If at a point the filter element requires inspection or replacement due to physical wear, the entire element can beretrieved from the outer vessel top-end.
