Overview
The HengaoDe HAD-6532P Salt Content Extraction Kit is a dedicated laboratory accessory system engineered for precise halide quantification in crude oils, topped crudes, cracked residues, and fuel oils—fully compliant with the methodology specified in GB/T 6532, “Determination of Salt Content in Crude Oil and Petroleum Products”. This kit implements the classical solvent extraction principle: samples are mixed with a polar solvent (typically isopropanol–toluene–water mixture), heated under controlled conditions to facilitate phase separation, and the aqueous extract is subsequently titrated potentiometrically or conductometrically for total chloride (expressed as NaCl equivalent). The apparatus supports quantitative analysis of halide concentrations within the range of 0.002–0.02 wt%, making it suitable for both routine refinery QC and forensic evaluation of seawater contamination in turbine oils and marine fuels.
Key Features
- Designed strictly per GB/T 6532 test protocol—including heating ramp profile, reflux configuration, and phase separation geometry
- Adjustable solid-state voltage regulator enabling continuous 0–220 V output to the heating element, ensuring reproducible thermal control across the 0–300 W power range
- Stainless steel heating mantle with integrated thermal insulation and stable base mount for consistent heat transfer and operator safety
- Standardized glassware set: reflux condenser (250 mm), separatory funnel (1 L), calibrated extraction vessel, and graduated receiver—all borosilicate 3.3 (e.g., Pyrex®-equivalent)
- Integrated grounding and overcurrent protection meeting IEC 61010-1 safety requirements for laboratory electrical equipment
- Compact footprint (420 × 300 × 500 mm) optimized for benchtop deployment in QC labs with limited space
Sample Compatibility & Compliance
The HAD-6532P kit accommodates viscous and heterogeneous feedstocks including untreated crude, atmospheric residue, vacuum gas oil, and residual fuel oil (e.g., RMG 380, RMK 700). It has been validated for use with ASTM D6470 (Salt Content in Crude Oil by Potentiometric Titration) and ISO 6297 (Petroleum Products — Determination of Salt Content) via method equivalence assessment. While GB/T 6532 remains its primary normative reference, the physical configuration and thermal performance align with GLP-compliant workflows. All components comply with RoHS Directive 2011/65/EU and are CE-marked for laboratory use within the European Economic Area.
Software & Data Management
This is a standalone hardware-only extraction system; no embedded firmware or proprietary software is included. Data acquisition and reporting are performed externally using standard laboratory information management systems (LIMS) or spreadsheet-based templates aligned with ISO/IEC 17025 documentation requirements. Users may integrate the HAD-6532P into automated workflows via analog voltage output (0–5 V) from optional external temperature monitoring modules (not supplied). For regulatory environments governed by FDA 21 CFR Part 11, manual entry of extraction parameters (time, voltage, ambient humidity) into auditable electronic lab notebooks (ELN) is recommended and fully supported.
Applications
- Routine salt content screening in upstream and downstream petroleum laboratories
- Investigation of pipeline corrosion risk due to chloride-induced stress cracking
- Verification of desalting unit efficiency in crude distillation units (CDUs)
- Forensic assessment of seawater ingress in lubricants used in marine propulsion systems
- Quality conformance testing for bunker fuel deliveries per ISO 8217:2017 Annex B
- Method development and validation studies supporting ASTM D3229 and IP 288 revisions
FAQ
Is the HAD-6532P compatible with ASTM D6470?
Yes—the extraction geometry, heating control resolution, and glassware dimensions satisfy the operational equivalency criteria defined in ASTM D6470 Annex A1 when used with standardized titration instrumentation.
Does the kit include titration reagents or electrodes?
No. The HAD-6532P supplies only the extraction hardware. Standard silver nitrate titrant, potassium chromate indicator (for Mohr method), or Ag/AgS reference electrodes must be sourced separately.
Can it be used for non-petroleum samples such as biofuels or shale oil condensates?
With method validation per ISO/IEC 17025 Clause 7.2.2, yes—though solubility behavior and emulsion stability must be assessed prior to adoption.
What maintenance is required for long-term reliability?
Annual calibration of the voltage regulator output against a certified multimeter and visual inspection of glassware for etching or stress fractures are recommended.
Is technical support available for method troubleshooting?
HengaoDe provides English-language application notes and GB/T 6532 interpretation guides upon request; on-site service is available through authorized regional partners in APAC and EMEA.
