GB/T 17280-2017Standard test method for distillation of crude petroleum - 15-theoretical plate column (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 17280-2009 "crude oil distillation standard test method 15-theoretical plate distillation column," and GB/T 17280- Compared to.2009, the main technical changes are as follows:

--- Remove the normative references GB/T 2540 and ASTMD4177, an increase of normative references GB/T 27867 (see Chapter 2,.2009 Edition, Chapter 2);

--- Removed "meaning and purpose" (see the.2009 edition of Chapter 5);

--- Increasing the use of devices that are similar to the original standard vacuum gauge (see 5.3.2.1,.2009 Edition 6.3.2);

--- Modify the contents of

12.3.2 Note (see 12.3.2,.2009 edition 14.3.2);

--- Added Chapter 13 "Quality Assurance and Control";

--- Increased n-tetradecane nitrogen content during distillation (see E.3.1.2);

--- Added the possibility to use devices similar to the original standard pressure gauge (see G.1.3, G.3.1.2 and G.3.1.4,.2009 Editions F.1.3, F.3.1.2 and F.3.1.4).

1 Scope

GB/T 17280-2017 is the Chinese national standard on standard test method for distillation of crude petroleum - 15-theoretical plate column, in the field of petroleum and related technologies. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 29 December 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 July 2018. Classification: ICS 75.040, CCS E21. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the Reid vapor pressure is not greater than 82.7kPa stable crude oil distillation test method. This standard specifies the distillation column using 14 to 18 theoretical plates, distilled at a reflux ratio of 5. 1, eventually reaching constant The mass of the liquefied gas, the distillation fraction and the residue fraction was obtained under the test conditions of a pressure-equivalent cutting temperature (AET) of 400 ° C, and each fraction Mass yield or volumetric yield, followed by a plot of the true boiling point (TBP) distillation curve with the cutting temperature. This standard applies to liquefied petroleum gas, light naphtha and the initial boiling point higher than 400 °C distillate oil mixture outside.

3 Terms and definitions

The following terms and definitions apply to this document.

3.1 Adiabaticity The entire distillation column has no significant increase in heat or loss of heat. When the distillation column heat loss occurs, the column back reflux than stigma Flow abnormally increased. The column insulation sleeve overheating, the situation is the opposite.

3.2 Steamed rate boiluprate The amount of steam entering the distillation column per unit of time.

3.3 Crude debutanizationofcrudepetroleum Light hydrocarbons (including n-butane) before n-butane in crude oil are removed, leaving heavier hydrocarbons. In practice, crude oil is butane is meant to be present More than 95% of C2-C4 and less than 5% of C5 hydrocarbons in the original sample are collected in the cold trap.
