INTRODUCTION:
The Groth Model 8331 Condensate Accumulator is a large volume chamber which stores and evacuates condensate liquid from biogas
process pipelines. The Condensate Accumulator allows the condensate to drain from the pipeline while preventing any gas from
escaping. This unit is typically installed downstream from a biogas digester, at the lowest point of the digester gas piping. The removal
of condensate from the biogas is necessary to keep the gas train running by protecting the downstream equipment and piping from
corrosion, blockage and water hammer.
The Condensate Accumulator must be maintained by a knowledgeable valve technician. It should only be assembled under clean
conditions preferably in a shop environment. Carefully read and understand this Manual before installing or repairing this product.

DESIGN, FUNCTION & OPERATION
The condensate accumulator is designed to allow condensate to drain without allowing process gas to escape. An internal drip leg is
used to automatically empty the condensate from the tank. The drain piping will prevent any gas from escaping the vessel. The vessel
is operated with a water seal and the internal drip leg will drain the amount of condensate that is added to the water seal.
The operation of removing condensate from within the Condensate Accumulate is managed by a piped connection (drip leg) which
penetrates the tank wall, which extends down to the drain elevation. As the condensate level rises to the level of the drain, it will be
evacuated through the drip leg. Groth also offers the option of a liquid level switch and solenoid valve (drip leg discharge) for
management of condensation from the biogas system.
