How do you convert BTU per lb to BTU per scf?
Btu / scf = Btu / lb X MW / 379.5 where: MW = molecular weight of the gas, lb / lb-mol The constant 379.5 is the molar volume at standard conditions of 14.696 psia and 60°F
How many cubic feet of nitrogen are needed to raise the pressure in an 8 inch diameter pipe 400 feet long to 20 psi?
47,298 SCF
How do you calculate the volume of natural gas in a pipeline?
You could use the following Rule of Thumb: Multiply the square of the inside diameter, in inches, by the gauge pressure, in psi; multiply this by 0.372; the answer is the approximate number of cubic ft of gas (standard conditions) in 1,000 ft of line, e.g 7 inch ID pipeline, 8km long, operating at 65 barg: 8 km = 26246 ft = 26.246 kft 65 Bar = 942.7 psi so, 7 x 7 x 942.7 x 0.372 = 17183.5356 scf / 1000 ft of line, so total gas in 26246 ft of line = 17183.5356x26.246=450999.0753576 = 0.45 MMSCF of gas. Or, you could use, Pv=znRT, assume a z of, say 0.9 , lets say the pipeline is at 6 deg (normal temperature for a shutin subsea pipeline in the north sea) 65x (Pi x 0.1778 x 0.1778 x 8000/4) = 0.9 x n x 8.314x10-5)x (273+6) n = 618523 moles 1 kmol of a gas occupies 22.441 Nm3 at standard conditions t.f 618.523 kmol should ocupy 618.523 x 22.441 = 13880.274643 Nm3. 1 Nm3 = 37.326 SCF, therefore, 13880.274 Nm3 = 518095.131324618 SCF = 0.52 MMSCF.(Nm3 to SCF conversion seems to have different factors, I've seen it range from 34.89 to 38.9!!!). Not very far from the 0.45 the rule of thumb calculated!!!. It should be noted that the standard volume is independent of the particular gas in the pipeline, so we don't need to knwo the MW or density. Any gas at a given P&T will have the same number of moles (and hence standard cubic feet), the actual mass in kg will ofcourse depend on the molecular weight. Riz If you mean standard or normal volume, in case the pressure is considerably higher than the atmospheric value, you need to use an expression for the compressibility factor or take it from a table, depending on the values of pressure and temperature in the pipeline. You can then use a state equation for the gas (knowing its molecular mass), from which you'll be able to calculate its density at working conditions. By multiplying the density by the physical volume of the pipeline pi*D^2/4*L (L=length, D=diameter) you obtain the mass of gas, which divided by the standard or normal density gives you the desired volume.
How do you convert scfm natural gas to mcf?
(mcf/day*1000)/24=scf/hr (scf/hr)/24=scf/min
What is a scuff for natural gas transportation?
It is how you measure gas volumes: "scf"= standard cubic foot of gas.
How you can convert natural gas condensate to natural gas volume equivalent?
Veq = 133000*(Condensate specific gr/Mol wt of condensate) in SCF/STB Where, Mol wt of condensate = 6084/(API-5.9)
1 scf natural gas heat value?
1 scf = 1 standard cubic foot 1 scf is the volume of gas at STP STP = Standard Temperature and Pressure STP (USA system of units) Standard Temperature = 60 degrees Fahrenheit Standard Pressure = 1 atmosphere at sea level = 14.696 pounds per square inch absolute The energy content of 1 scf natural gas = 1020 BTU (British Thermal Units)
How many ccf 1 scf?
100
How many ccf in 1 scf?
100
How many liters does 1000 FTS of Liquid Nitrogen equal?
According to metal-wear, one liter of LN2 will make 22.8 standard cubic feet (scf) of gas. 1 scf equals approximately 1 FTS, the exact conversion depends on the ambient temperature and pressure. So 1000 FTS / 22.8 scf = 43.9 liters of liquid nitrogen.
How do you convert normal cubic feet of gas to standard cubic feet of gas?
The formula is: Normal Cubic Feet = SCF * [T / (273 + 15.6)] * [ 14.73 / P] SCF = Standard Cubic Feet T = Temperature in kelvin P = Pressure in psi (absolute pressure, where 1 atmosphere = 14.73)
How does HCF relate to scf?
There are over a hundred meanings for scf, none of which appear to have much to do with HCF. If you spell out HCF and scf in full, you may have a better chance of a useful answer.
How do you convert BTU per lb to BTU per scf?
Btu / scf = Btu / lb X MW / 379.5 where: MW = molecular weight of the gas, lb / lb-mol The constant 379.5 is the molar volume at standard conditions of 14.696 psia and 60°F
