GOST 22387.3-77 PDF

Full title and description

GOST 22387.3-77 — Natural gases. Method for determination of oxygen. Specifies an absorption method for measuring the volumetric content of oxygen in natural gas using a pyrogallol-based absorbent after removal of acidic components from the sample.

Abstract

This standard (GOST 22387.3-77) defines laboratory apparatus, reagents and a stepwise procedure to determine the volume fraction of oxygen in natural gas by absorption (pyrogallol A), as well as result processing and declared accuracy. It was developed for routine quality control of natural gas and for analytical verification in gas handling and distribution systems.

Scope

The standard applies to natural gases and prescribes an absorption technique to determine the volumetric fraction of oxygen. The method’s essential steps are removal of acidic components from the gas sample, passage of the cleaned gas through a pyrogallol A solution which absorbs oxygen, and measurement of the volume of gas absorbed to compute oxygen content. It was intended for laboratory quality control and regulatory testing of gas supplied for distribution and use.

Key topics and requirements

• Scope and applicability — natural gas analysis for oxygen content.
• Required apparatus — gas sampling and gas-analysis laboratory equipment (e.g., KGA-type setups), absorption vessels and volumetric measuring devices.
• Reagents — pyrogallol A solution (prepared and standardized), drying and neutralization reagents for removing acidic components.
• Sample preparation — pre-cleaning to remove corrosive/acidic constituents before absorption.
• Procedure — controlled gas flow through absorbent, measurement of absorbed oxygen volume, calculation of volumetric fraction.
• Accuracy and performance — declared precision and repeatability requirements for the method and reporting conventions.
• Normative references — links to related GOSTs for reagents, apparatus and measurement rules incorporated by reference.

Typical use and users

Laboratories performing quality control of natural gas, gas producers and processors, distribution companies, metrology and regulatory bodies, and R&D groups involved in gas composition analyses use (or historically used) this method. It was suitable for routine acceptance testing, safety checks and regulatory compliance where oxygen content influences corrosion, combustion, or gas quality.
