Overview
The SPECTRA INVENT HX-DR1505A Automatic Vacuum Distillation Apparatus is a precision-engineered system designed for the standardized determination of distillation characteristics of petroleum products and fractions that are thermally unstable under atmospheric conditions. It operates on the principle of reduced-pressure (vacuum) distillation, enabling controlled boiling point distribution analysis at elevated temperatures—up to 400 °C—without thermal decomposition. The instrument conforms to internationally recognized test methods including ASTM D1160 (High-Boiling Point Petroleum Products – Vacuum Distillation), ASTM D2892 (Fractionation of Crude Petroleum at Reduced Pressure), and ASTM D5236 (Vacuum Fractionation of Heavy Hydrocarbons). Its modular architecture integrates a programmable heating mantle, vacuum regulation module with absolute pressure control (typically 1–100 mmHg, adjustable in 0.1 mmHg increments), calibrated temperature sensing (Pt100 Class A), and automated fraction collection driven by real-time vapor temperature feedback. This ensures high reproducibility across replicate runs and alignment with GLP-compliant laboratory workflows.
Key Features
- Automated vacuum control with digital pressure regulation and real-time monitoring via integrated absolute pressure transducer
- Programmable distillation ramping profiles with up to 5 independent heating zones and dynamic power modulation
- Temperature measurement traceable to NIST-certified Pt100 sensors (±0.1 °C accuracy from 30–400 °C)
- Cold bath subsystem with Peltier-based cooling and PID-controlled circulation (5–80 °C range, ±0.2 °C stability)
- Motorized fraction collector with 12-position receiver carousel and auto-triggered switching based on temperature or volume thresholds
- Integrated safety interlocks: overtemperature cutoff, vacuum loss alarm, coolant flow monitoring, and emergency venting
- Front-panel touchscreen interface with onboard method storage (≥100 user-defined protocols) and USB data export
Sample Compatibility & Compliance
The HX-DR1505A accommodates liquid hydrocarbon samples ranging from light vacuum gas oils to heavy residua, provided they exhibit measurable volatility under reduced pressure (vapor pressure ≥0.1 mmHg at test temperature). Compatible sample volumes: 100–200 mL per run. The system supports both single-stage (ASTM D1160) and multi-stage (ASTM D2892/D5236) vacuum distillation protocols. All hardware components—including condenser geometry, column packing, and receiver design—meet dimensional and material specifications outlined in ASTM E177 and ISO/IEC 17025 reference requirements for distillation apparatus validation. Data integrity features include electronic audit trail, user access levels (admin/operator), and timestamped event logging compliant with FDA 21 CFR Part 11 principles for regulated environments.
Software & Data Management
The instrument operates with embedded firmware supporting method-driven automation and real-time graphical display of key parameters: vapor temperature vs. cumulative recovered volume (% v/v), pressure profile, and cold bath setpoint tracking. Raw data (CSV format) includes time-stamped temperature, pressure, volume collected, and heater output. Optional PC software (SPECTRA DistilSuite™ v3.2) provides advanced post-processing: TBP (True Boiling Point) curve generation, cut-point interpolation, ASTM D86/D1078 correlation mapping, and automated report generation in PDF/Excel formats. All exported files retain full metadata (operator ID, method version, calibration certificate IDs) and support LIMS integration via ASTM E1384-compliant XML schema.
Applications
- Determination of vacuum gas oil (VGO) boiling point distribution for FCC feed characterization
- Quality control of lubricating oil base stocks per ASTM D2500 and IP 178
- Analysis of heavy crudes and bitumen fractions under simulated vacuum tower conditions
- Research-scale fractionation of synthetic crude and bio-oil derivatives
- Validation of refinery simulation models (e.g., Petro-SIM®, HYSYS®) using experimental TBP data
- Compliance testing for military fuel specifications (MIL-DTL-83133, MIL-PRF-25959)
FAQ
What vacuum pressure range does the HX-DR1505A support?
The system achieves and maintains absolute pressures from 0.1 mmHg to 100 mmHg, with closed-loop regulation accuracy of ±0.05 mmHg within the 1–50 mmHg operational band.
Is calibration verification documented per ISO/IEC 17025 requirements?
Yes—each unit ships with a factory calibration certificate covering temperature sensors, pressure transducer, and volumetric receivers, with traceability to national metrology institutes (NIM, China). On-site verification kits and SOPs are available.
Can the instrument be integrated into an existing LIMS environment?
Yes, via optional Ethernet interface and ASTM E1384-compliant data export; custom API integration support is provided under extended service contracts.
Does the system comply with ASTM D2892 for multi-fraction vacuum distillation?
Yes—the column height, reflux ratio control, and fraction collection logic fully satisfy the mechanical and procedural requirements of ASTM D2892 Annex A1.
What maintenance intervals are recommended for long-term operational reliability?
Vacuum pump oil replacement every 500 hours; pressure sensor recalibration annually; cold bath coolant exchange biannually; full system performance verification semiannually per ASTM D4057 guidelines.
