How do you calculate gas to liquid ratio?
Fluid Properties The gas–liquid ratio is the ratio of a volume of gas divided by a volume of liquid at the same temperature and pressure. The gas–liquid ratio, or GLR, is useful for characterizing the behavior of a reservoir. The choice of GLR depends on the fluids in the reservoir.
How is LG calculated?
Considering data from a heat and mass balance the dry air rate and the prevailing L/G ratio in the tower can be calculated: L/G = ha / [Cw x (tw2 – tw1)] = Cw = specific heat of water = 1.0.
What is minimum liquid gas ratio?
By material balance for the solute in the gas, the amount to be removed is G ( y1 – y2 ). The least amount of liquid Lmin that can remove this amount of solute is the minimum liquid rate, often expressed in terms of a liquid-to-gas ratio, Lmin/G.
What is liquid to gas ratio in venturi scrubber?
Commercial venturi scrubbers, the design of which has been established by trial and error procedures and testing, operate at velocity ratios of 0.5 or greater at liquid to gas ratios of about 28 gal/1000 acf or less as shown in Figure 4.
What is solution GOR?
The solution gas-oil ratio (GOR) is a general term for the amount of gas dissolved in the oil. Heavy oils (lower API gravity) has lower capacity to contain dissolved gas than lighter oils. Solution GOR in black oil systems typically range from 0 to approximately 2000 scf / bbl.
How do you calculate Gvf?
The basic governing equation of the steady GVF in open channels is given by [22], [23](1) dy dx = S 0 – S f 1 – F 2 where y = depth of flow (m), x = distance along the channel, measured positive in the downstream direction (m), dy/dx = slope of the free surface at any location x, S0 = longitudinal slope of the channel …
What is L G ratio of cooling tower?
The L/G ratio of a cooling tower is the ratio between the water and the air mass flow rates. Thermodynamic rules also dictate that the heat removed from the water must be equal to the heat absorbed by the surrounding air.
What is pump friction loss?
Friction loss is the loss of energy or “head” that occurs in pipe flow due to viscous effects generated by the surface of the pipe. Friction Loss is considered as a “major loss”. “Head” is a very convenient term in the pumping business.
What is L G ratio of absorption?
L/G ratio illustrates a number of points about the choice of wet scrubbers used for gas absorption. Also, the liquid-to-gas ratio for the absorption process is higher than for particle removal and gas velocities are kept low to enhance the absorption process.
What is operating line in mass transfer?
Operating lines define the mass balance relationships between the liquid and vapour phases in the column. There is one operating line for the bottom (stripping) section of the column, and on for the top (rectification or enriching) section of the column.
What is venturi wet scrubber?
A Venturi Scrubber is a type of pollution control equipment that is used to remove contaminated particles from gaseous exhaust streams. Named after an Italian physicist, the Venturi effect occurs when gas or fluid is pushed through a throat, or choke, to increase the velocity of the fluid or gas stream passing through.
How does a wet venturi scrubber work?
A venturi scrubber accelerates the waste gas stream to atomize the scrubbing liquid and to improve gas-liquid contact. In a venturi scrubber, a “throat” section is built into the duct that forces the gas stream to accelerate as the duct narrows and then expands.
