Full title and description

UOP 910-07 — "Total Chloride in LPG and Gaseous Hydrocarbons by Microcoulometry". This UOP test method specifies oxidative combustion/microcoulometric procedures for the determination of total chloride (organic + inorganic) in liquefied petroleum gas (LPG) and other gaseous hydrocarbons, with trace-level sensitivity for quality control and process monitoring.

Abstract

UOP 910-07 (issued 29 Aug 2007) provides a microcoulometric (combustion + coulometric titration) test procedure to measure total chloride in LPG and gaseous hydrocarbon streams. The method covers samples with chloride concentrations roughly from 1 to 1000 ng/mL for gases (or mass‑ppm/µg/g for LPG). The procedure notes interferences (e.g., high sulfur levels) and treats other halogens (except fluoride) as chloride for reporting. Typical analytical range, detection limits and sample types are described in the method text.

Scope

This method is intended for the determination of total chloride in gaseous hydrocarbons and LPG at trace levels (approx. 1–1000 ng/mL for gases; mass‑ppm/µg/g for LPG). It applies to both organic and inorganic chloride species that are converted to a measurable chloride form by oxidative combustion and detected by microcoulometry. The method warns that if sulfur is present above about 1 mass‑% quantitative chloride determination may be compromised. Other halogens present (except fluoride) are typically reported as chloride equivalents.

Key topics and requirements

• Analyte: total chloride (organic + inorganic) in LPG and gaseous hydrocarbons.
• Principle: oxidative combustion (pyrolysis/combustion) of sample followed by microcoulometric detection (coulometric titration of generated chloride).
• Applicable sample types: LPG, light gaseous hydrocarbon streams and similar matrices with low‑boiling hydrocarbon composition.
• Analytical range / detection: approximately 1 to 1000 ng/mL (gas) or corresponding µg/g (LPG); method includes limits of detection/quantification appropriate for trace chloride analysis.
• Interferences and limitations: high sulfur (>~1 mass‑%) can prevent quantitative chloride determination; fluoride is treated separately; other halogens may be calculated as chloride.
• Reporting and units: typically reported as total chloride concentration (mass‑ppm or ng/mL) with method-specified sample handling and calibration procedures.
• Instrumentation and safety: requires combustion-capable analyzers and microcoulometric titration cells; oxygen supply and combustion safety procedures are standard.

Typical use and users

Used by refinery and petrochemical quality control laboratories, LPG producers and suppliers, gas-analysis service labs, and instrument manufacturers/integrators supplying combustion‑coulometry analyzers. The method supports product quality acceptance, corrosion risk assessment, process monitoring and specification compliance where trace chloride is a concern. Instrument vendors commonly reference UOP 910 alongside related ASTM/ISO methods when describing compliant analyzers.

Related standards

UOP 910-07 is part of a family of halogen/chlorine test methods used in the petroleum sector. Commonly referenced related standards include ASTM methods (for combustion/coulometric chlorine analysis) such as ASTM D4929, ASTM D5808, ASTM D7457 and ISO/EN methods covering total halogen/chlorine analysis; other UOP methods for chloride/halogen in different matrices (e.g., UOP 779, UOP 1013, UOP 979) may also be relevant. Instrumentation suppliers typically list UOP 910 together with these ASTM and ISO references.
