A
system configured to conduct a two-phase gas-
solid conveying test under controlled pressure and flow conditions, the
system comprising a
gas pressure supply unit comprising at least one gas pressurizing device configured to receive and pressurize a gas
stream and deliver the pressurized gas
stream to a gas inlet line; a cooling unit disposed at a downstream of the
gas pressure supply unit and connected in fluid communication therewith, the cooling unit configured to regulate a temperature of the pressurized gas
stream; a gas flow
control unit disposed at a downstream of the cooling unit and connected in fluid communication therewith, the gas flow
control unit configured to regulate either a flow rate and a velocity of the pressurized gas stream through the gas inlet line, the gas flow
control unit comprising at least one flow measuring device and at least one flow regulating valve; a two-phase transport unit disposed at a downstream of the gas flow control unit and connected in fluid communication therewith, the two-phase transport unit comprising a two-phase transport line configured to convey a two-phase gas-
solid flow and at least one
pressure monitoring device disposed along the two-phase transport line and configured to monitor pressure drop during the two-phase gas-
solid conveying test; a solid-phase feeding unit mechanically coupled and fluidly connected to the two-phase transport line, the solid-phase feeding unit configured to deliver a plurality of solid particles into the two-phase transport line to form the two-phase gas-solid flow; and a product collection and separation unit disposed at a downstream of the two-phase transport unit and connected in fluid communication therewith, the product collection and separation unit configured to receive the two-phase gas-solid flow, separate a solid phase from a
gas phase, and
discharge the
gas phase to an atmospheric outlet.
