Spectra Invent HX-DR1515A Automated Crude Oil Distillation Apparatus (Single-Tube)

Overview

The Spectra Invent HX-DR1515A Automated Crude Oil Distillation Apparatus (Single-Tube) is a precision-engineered system designed for standardized atmospheric distillation analysis of petroleum products in accordance with GB/T 26984–2011. It implements classical ASTM D86–23 and ISO 3405–2017 compliant distillation methodology—employing controlled heating, real-time temperature–volume correlation, and automated endpoint detection to characterize the volatility profile of crude oil and refined fractions. The instrument integrates a JUMO-certified PT100 temperature sensor array, infrared radiation heating with dynamic thermal management, and a Danfoss compressor-based cold bath to maintain precise condensate cooling across the full 0–60 °C range. Its single-tube configuration ensures method reproducibility while minimizing cross-contamination risk and simplifying calibration traceability—making it suitable for routine QC laboratories, refinery process control labs, and third-party testing facilities operating under GLP or ISO/IEC 17025 frameworks.

Key Features

• Intelligent heating control system dynamically regulates infrared power output to sustain a stable distillation rate of 4–5 mL/min, meeting strict requirements of GB/T 26984 and ASTM D86.
• Five programmable experiment termination modes: final boiling point (FBP) detection, dry point detection, user-defined temperature threshold, user-defined recovered volume threshold, and manual keyboard abort—with full printout of results upon completion.
• High-resolution volumetric measurement (0.1 mL resolution over 0–100 mL range) via optically calibrated cylinder interface with ambient temperature stabilization (5–50 °C internal circulation zone).
• Integrated real-time data logging with timestamped temperature–volume pairs; supports user-defined recording points—either temperature-triggered (e.g., “record volume at 150 °C”) or volume-triggered (e.g., “record temperature at 50 mL recovered”).
• Onboard real-time clock with 95-year operational lifespan eliminates manual date entry and supports audit-ready chronological traceability.
• 40-column dot-matrix thermal printer with native Chinese character support delivers immediate hard-copy reports compliant with internal QA documentation standards.

Sample Compatibility & Compliance

The HX-DR1515A is validated for atmospheric distillation of light to heavy petroleum streams including gasoline, kerosene, diesel fuel, fuel oil, and crude oil blends. It conforms to national and international standards governing distillation behavior: GB/T 26984–2011 (Crude Oil Distillation Characteristics), ASTM D86–23 (Standard Test Method for Distillation of Petroleum Products at Atmospheric Pressure), and ISO 3405–2017 (Petroleum Products — Determination of Distillation Characteristics at Atmospheric Pressure). All thermal sensors are traceable to NIST-equivalent references via JUMO’s factory calibration certificate. The system architecture supports 21 CFR Part 11–ready software add-ons (optional wired/wireless PC interface) for electronic signature, audit trail, and user access control when deployed in regulated environments.

Software & Data Management

While the HX-DR1515A operates autonomously via its embedded microcontroller and color LCD interface, optional PC connectivity enables advanced data handling. Through configurable RS-232 or Wi-Fi modules (user-selectable), laboratories may integrate the instrument into LIMS or ELN platforms. Exported datasets include CSV-formatted time-stamped temperature–volume curves, endpoint metadata (IBP, FBP, dry point), and operator ID logs. Firmware supports firmware versioning, parameter backup/restore, and calibration history storage—facilitating periodic verification per ISO/IEC 17025 Clause 6.4.2. No proprietary runtime or subscription licensing is required for basic operation or data export.

Applications

• Routine specification testing of refinery feedstocks and finished fuels against commercial grade limits (e.g., ASTM D975 for diesel, D439 for gasoline).
• Crude assay support: determination of initial boiling point (IBP), 10%, 50%, 90%, and final boiling point (FBP) to inform fractionation column design and cut-point optimization.
• Quality assurance in lubricant base stock production where volatility affects NOACK volatility and flash point performance.
• Regulatory compliance testing for customs clearance, environmental reporting (e.g., EPA Method IP 286), and product certification bodies.
• Educational use in petroleum engineering curricula for hands-on demonstration of vapor–liquid equilibrium principles under atmospheric conditions.

FAQ

What distillation standards does the HX-DR1515A support?

It natively executes GB/T 26984–2011 and is fully compatible with ASTM D86–23 and ISO 3405–2017 methodologies through adjustable rate control and endpoint logic.
Is the system compliant with FDA 21 CFR Part 11 requirements?

The base unit is not Part 11–certified out-of-the-box, but optional PC software with electronic signatures, audit trails, and role-based access control can be deployed to meet Part 11 criteria in validated environments.
Can the cold bath operate continuously at 0 °C?

Yes—the Danfoss compressor-based refrigeration system maintains stable setpoints between 0 °C and 60 °C with ±0.3 °C stability over 8-hour continuous operation.
How is temperature accuracy verified and maintained?

Each unit ships with a JUMO calibration certificate for the PT100 sensor; users may perform field verification using NIST-traceable dry-block calibrators or reference thermometers per ISO/IEC 17025 Section 6.6.
What maintenance is required for long-term reliability?

Annual inspection of condenser tubing integrity, cleaning of infrared heater reflectors, verification of volumetric cylinder optical path clarity, and refrigerant pressure check—documented in the included maintenance log template.
