Condensate and Sediment Trap – 233 Series

The 233 Series Condensate and Sediment Trap is designed to remove liquid and solids from wet, dirty waste gas, assisting in protecting downstream equipment from corrosion, clogging, or water hammer.

Introduction

The Varec Biogas 233 Series Condensate and Sediment Trap should be installed immediately downstream from each digester to remove the large volume of water which condenses when the gas cools as it exits the digester. In addition, sediment which is entrained in the gas will drop out and accumulate in the trap, protecting downstream equipment from damage caused by solids. Varec Biogas Model 233 Condensate and Sediment Traps may be installed at other locations in the gas system where large volumes of water must be removed.

These sediment traps are designed for working pressures up to 25 psig (172 kPa). NOTE: When a Varec Biogas Drip Trap is installed, the pressure rating of the drip trap determines the maximum allowable working pressure for the assembled unit.

Operation

Condensate and sediment are removed automatically from the waste gas as it flows through the Varec Biogas 233 Sediment Trap. Such removal is accomplished by the combination of centrifugal force and a sharp drop in velocity as the gas enters the trap.

The condensate/sediment trap features a large reservoir capacity with the inlet flange designed to swirl the gas and an internal baffle located at the base of the reservoir to provide efficient separation of entrained solids. Storage capacity is a minimum of six gallons sediment and six gallons condensate. Consult factory for larger capacities.

A removable top cover provides interior access and includes an integral 3/4-inch NPT inspection pipe for measurement of the condensate and sediment. A large, 2-inch blowout and drain connection allows accumulated sediment to be easily cleaned from the trap.
