We offer a complete line of floating piston and rodded transfer vessels. These
vessels can be used for a variety of purposes and applications. These vessels have
been used for Petroleum Core Flooding experiments, Supercritical Carbon Dioxide,
PVT experiments, Catalysis, Polymerization, Oxidation, Hydrogenations, and other
Reactor studies. In an experiment where multiple fluids or phases are to be injected
into the system, a series of accumulators are installed into the system and then
only one metering pump is required to inject the fluids in sequence. These vessels
also protect the metering pumps from highly corrosive or high brine liquids, so
that the precision metering pump is not damaged.
These vessels have several unique features. The bronze end caps are used to prevent
galling between similar metals. The seal and end plug design allow for hand tight
operation of the vessel. This feature allows easy assembly and disassembly of the
vessel for cleaning and inspection. As the end plug is inserted into the vessel,
the end plug will not rotate and perhaps damage the seal or sealing surface area.
The piston material can be Teflon, which prevents any galling from occurring between
the piston and the honed cylinder wall.
For high pressure gas and rodded transfer vessels, the Teflon piston is replaced
with a metal piston. The metal pistons are used for Teflon seals or Viton seals,
and have guide rings to prevent galling between the piston and the inner diameter
of the cylinder. When a rod is attached to the piston, the rod will indicate the
position of the piston. A liner transducer can be attached to the rod to measure
the fluid or gas volume within the vessel, or displaced from the vessel.
