TimePower TP662 Automatic Distillation Apparatus for Petroleum Products

Overview

The TimePower TP662 Automatic Distillation Apparatus is a fully integrated, ASTM D86-23 and ISO 3405 compliant distillation system engineered for precise boiling point distribution analysis of petroleum products and volatile organic liquids. It implements classical batch distillation methodology under controlled atmospheric conditions, utilizing calibrated vapor-phase temperature sensing and real-time condensate volume tracking to generate standardized distillation curves. The instrument operates on the principle of sequential heating, vaporization, condensation, and volumetric collection—aligned with standard test methods for gasoline, aviation turbine fuels, naphthas, diesel fractions, solvent blends, and industrial organic solvents. Its modular firmware architecture coordinates thermal ramping, refrigeration control, optical liquid-level detection, and data logging without manual intervention, delivering reproducible results traceable to national metrological standards.

Key Features

• 10.4-inch high-resolution color touchscreen interface with intuitive workflow navigation and real-time graphical display of temperature vs. recovered volume
• Imported Pt100 platinum resistance thermometer (DIN Class A) for vapor temperature measurement with ±0.1 °C accuracy across 0–400 °C range
• High-stability Danfoss (Secop) hermetic compressor enabling rapid, uniform cold bath cooling between 0 °C and 60 °C
• Optical liquid-level tracking system with imported photoelectric sensor for volume measurement resolution of 0.1 mL and repeatability within ±0.1 mL
• Integrated barometric pressure sensor for automatic correction of observed temperatures to standard atmospheric pressure (101.3 kPa), satisfying ASTM D1078 and ISO 9199 requirements
• Selectable termination logic: end test either at user-defined vapor temperature or cumulative condensate volume threshold
• Dual-zone thermal management: independently adjustable recovery chamber temperature (10–40 °C) ensures consistent condensate handling per ASTM D86 Annex A1
• Manual nitrogen purge function for emergency flame suppression, mitigating thermal runaway risk during high-boiling fraction distillation

Sample Compatibility & Compliance

The TP662 supports standardized distillation testing of hydrocarbon-based samples conforming to ASTM D86 (Standard Test Method for Distillation of Petroleum Products at Atmospheric Pressure), ASTM D1078 (Volatility of Volatile Organic Liquids), ISO 3405 (Petroleum Products — Determination of Distillation Characteristics), and GB/T 6536 (Chinese national standard equivalent). Compatible sample types include motor gasoline, aviation gasoline (Avgas), jet fuel (Jet A/A-1), kerosene, naphtha, light distillates, specialty solvents, and technical-grade organic volatiles. All hardware components—including distillation flask, condenser, receiver cylinder, and vapor temperature probe—are dimensionally and thermally calibrated per ASTM E29 and ISO/IEC 17025 guidelines. The system meets electromagnetic compatibility (EMC) requirements per IEC 61326-1 and safety specifications per IEC 61010-1 for laboratory equipment.

Software & Data Management

Firmware version 3.2 provides embedded data acquisition, curve visualization, and report generation in PDF/CSV formats. Each test record includes timestamp, ambient conditions, barometric correction factor, raw temperature-volume pairs, and annotated distillation curve (IBP, 10%, 50%, 90%, FBP). Audit trail functionality logs all parameter changes, operator IDs, and calibration events—supporting GLP and GMP documentation requirements. Data export complies with FDA 21 CFR Part 11 principles via optional password-protected user roles and electronic signature capability. No cloud dependency: all data reside locally on internal flash memory with USB backup support.

Applications

• Quality control of refinery streams including straight-run naphtha, catalytic reformate, and hydrotreated diesel
• Specification verification of finished fuels against ASTM D439 (gasoline), D1655 (jet fuel), and D975 (diesel)
• Volatility assessment of industrial solvents per ASTM D1310 and ISO 2719
• Research and development of alternative fuel blends requiring precise boiling point characterization
• Regulatory compliance testing for VOC content estimation and Reid Vapor Pressure (RVP) correlation studies
• Teaching laboratories conducting fundamental distillation thermodynamics experiments
