The gas flow rate through the sampling train, 250 to 500 mL/min (0.5 to 1 scfh
), was measured using a bubble meter before and after each sampling interval.
PES said the H Series generator at the Mirant-Zeeland plant provides 192 scfh
of 99.999-percent pure hydrogen gas.
Mixers in the standard two- and three-gas series provide flows up to 180 SCFH
. Mixers in the high-capacity two-gas series provide flows up to 700 SCFH
and are designed primarily for large manifold systems.
), two years later purchased a second unit with an output of 50 [Nm.sup.3]/hr.
A small rotameter (seen at the right of the ozonator box) provided final regulation of the influent oxygen flow rate up to 20 standard cubic feet per hour (scfh
) at 6 psig pressure.
EPA is requiring use of low-bleed controllers (bleed rate of 6 scfh
or less) between the wellhead and the point where gas enters the transmission pipeline.
* A cold air flow rate from 10 to 25 scfh
The 530 Series automatic switchover system delivers a continuous supply of high-pressure, non-corrosive, non-oxidizing gas at flows up to 4000 SCFH
. Users can select from 3000, 4500 or 6000 psig source pressures and can control outlet pressures in four delivery pressure ranges.
The small-footprint system provides an airflow rate of 300 SCFH
, a temperature range of -60[degrees]C to 200[degrees]C, and temperature-cycling, remote-control, and self-diagnostic capabilities.
Typical urea production conditions include an inlet pressure of 3,500 psig, an outlet pressure of 300 psig, an operating temperature of 350[degrees]F, and a flow rate of 8 million SCFH
. A valve typically used in this process would be a 4-in.
The design operates from a few inches of water column pressure up to 100 psig, and has a flow up to 1500 SCFH
of natural gas at a 10-psid pressure drop.
Additionally, Pdc said flow rates for the new compressors range from 50 to 2,000 standard cubic feet per hour (scfh
), using such suction sources as generators, reformers or tube trailers.
