The safety valve may be in fluid communication with a bleed tank for storing an outlet flow of test fluid from the vessel.

The purge port is in fluid communication with the purge tank.

A liquid drain valve (V4) is connected to the vessel and is closed during compression and open during drain/recharge.

A fitting body extends into the vessel wall aperture and the purge manifold aperture.

A filtration vessel has an inlet for inflow into the filtration vessel of liquid media to be filtered, a body of filter media in the filtration vessel, and a drain to receive filtered liquid media for take off from the filtration vessel.

The safety valve may be in fluid communication with a bleed tank for storing an outlet flow of test fluid from the vessel.

Release of the oil preferably occurs by means of blowing out with a compressed air nozzle (5) and trapping in a collecting trough (7).

A drain valve (79) is provided to purge accumulated contaminants from basin (70) while the filter (10) operates.

The pressure vessel has a vessel penetration passing through a wall of the pressure vessel.

Disposed in a shell is a coagulation sedimentation tank, a primary air flotation tank, an electrolysis air flotation tank, and a slag discharging tank.

Apparatus and a method for dewatering a bead suspension of fragile beads having a high water content suspended in a liquid include a staging vat (12), a metering vat (16), and a dewatering vat (20).

Lastly, refill the chamber with N2 and close off the inert gas supply, when the purging process is finished.

Each one of said vat modules (11) comprises an essentially horizontal vat floor (14) and four joining vat walls (15) that are connected to the vat floor (14) and that are leaving an open vat space (16).

A tank adapter connects the manifold to a treatment tank.

A gasification system having a combustor vessel, an optional scrubber vessel, an optional fixer vessel, an optional cyclone vessel and an optional demister vessel.
