The following pure components were added to the components list: The entire system is immersed in a water bath at F and once equilibrium is attained the observed pressure from the measuring device is reported as the Reid Vapor Pressure.

The vapor pressure of a mixture is commonly defined as the pressure where the first bubble of vapor is formed at a given temperature but there are other definitions based on standardized experimental measurements or correlations.

Request prices on the required pressure gauges, thermometer, sample transfer connection and manometer. Now, the RVPE is obtained through a new property as shown below.

Product Description The K Reid Vapor Pressure Cylinders are polished stainless steel test cylinders for vapor pressure tests of liquid petroleum products, volatile crude oil and liquefied petroleum gas LPG. All examples were calculated using VMGSim 9. General Use laboratory apparatus balances, baths, blenders, centrifuges, chart recorders, freezers, fume hoods, furnaces, glassware washers, glove boxes, mixers, moisture testing, ovens, pumps, shakers, vacuum equipment, water purification This option is activated through a check box that can be found in the Special Properties Unit Operation or the Refinery and Natural Gas tabs from the Material Stream as seen in the following figures.


What are your requirements. Right-click to open the PDF in a new window or download it: The method is very similar to Da but in this case the air saturation is not required.

Seta Reid Vapour Pressure Bath

Note that Nitrogen and Oxygen were added to the component list in order to be able to perform air saturation in the sample. Once this was done, a close match between calculated and experimental values of the distillation curve was obtained. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Gas Conditioning and Processing 7 th Ed. Units The Vapor Pressure is reported in absolute pressure units. Historical Version s – view previous versions of standard Translated Version s: True Vapor Pressure F This property is similar to the Vapor Pressure calculation except that the flash calculation is performed at a specific temperature of F.

This property is calculated based on an equation presented in the EPA publication, derived from a nomogram first published by the American Petroleum Institute APIwhich is based on the Reid D12267 Pressure Equivalent of non — pressurized vessels see definition below and the storage temperature. Oxidation Bomb for Petroleum Testing.

Type text as it appears:: IP is a test method for determination of the air-saturated vapor pressure of crude oil. The following table shows the comparison of those values with those calculated from VMGSim:. There has been widespread confusion related to the pressure units of this property. For determination of the vapor pressure of gasoline-oxygenate blends, refer to Test Method D Enter product namemake or model. The standard method establishes that the analyzed mixture must be placed in a sample container kept in a cooling bath at 32 Astmm.


Air saturation of the sample is performed by vigorously shaking the container and returning it to the cooling bath. Units The Vapor Pressure F is reported in absolute pressure units.

One-opening type is for gasoline and other products having a Reid Vapor Pressure below 26psi kPa. Specific warning statements are given in Sections 7 and 18and Validation examples are also included.

This test method covers the Reid Vapor Pressure determination of gasoline, volatile crude oils, and other volatile petroleum products. Historical Version s – view previous versions of standard. The Reid Vapor Pressure is defined as the vapor axtm of a mixture as it was measured according to the experimental method depicted in the ASTM Da standard method [3].

Previous calculations in VMGSim did not take into account the air saturation, which caused the results to be lower. Available request a quote. Petroleum Gas Sampling Cylinder.

Consists of upper chamber and lower chamber in required 4:
