Overview
The Timepower TP6621 Automated Petroleum Distillation Apparatus is a fully integrated, microprocessor-controlled distillation system engineered for precise boiling point distribution analysis of petroleum fractions and volatile organic liquids. It operates on the standardized atmospheric distillation principle defined in ASTM D86, ISO 3405, GB/T 6536, and related specifications—measuring initial boiling point (IBP), final boiling point (FBP), and intermediate recovery temperatures (e.g., 10%, 50%, 90% v/v) under controlled heating and condensation conditions. The instrument employs a calibrated Pt100 platinum resistance thermometer (traceable to national standards) for temperature measurement, coupled with high-resolution optical liquid-level tracking to determine recovered volume with ±0.1 mL repeatability. Its modular firmware architecture synchronizes heating ramp control, cold bath refrigeration (via Secop Danfoss compressor), vapor temperature acquisition, and real-time data logging—enabling full automation from start to report generation without manual intervention.
Key Features
- 10.4-inch capacitive color touchscreen interface with intuitive workflow navigation and multilingual support (English, Chinese)
- Optical volume detection system using imported photoelectric sensor array for robust, drift-free distillate measurement
- Programmable recovery chamber temperature control (0–60 °C) to minimize condensation variability and improve reproducibility
- Integrated barometric pressure sensor for automatic correction of observed temperatures to standard atmospheric pressure (101.3 kPa)
- Real-time graphical display of temperature vs. recovered volume curves during distillation
- Flexible termination logic: user-selectable stop criteria based on either vapor temperature threshold or cumulative distillate volume
- Dual-zone thermal management: independent regulation of heating mantle and cold bath (0–80 °C range, ±0.2 °C stability)
- Compliance-ready architecture supporting audit trails, user access levels, and electronic signature capability per FDA 21 CFR Part 11 requirements when paired with validated software modules
Sample Compatibility & Compliance
The TP6621 is validated for routine testing of gasoline, aviation turbine fuel (Jet A-1), naphtha, kerosene, diesel fuel, solvent naphthas, and other hydrocarbon mixtures conforming to ASTM D86, IP 123, ISO 3405, GB/T 6536, GB/T 255, GB/T 7534, and GB 3146. It accommodates standard 125 mL ASTM distillation flasks and supports interchangeable insulation plates (38 mm and 50 mm thicknesses) to meet method-specific heat transfer requirements. All temperature sensors are calibrated against NIST-traceable references, and volumetric accuracy is verified using certified Class A 100 mL graduated cylinders. The system meets IEC 61000-4 electromagnetic compatibility standards and carries CE marking for safe operation in laboratory environments compliant with EN 61010-1.
Software & Data Management
The embedded control software provides full GLP/GMP-aligned data handling: time-stamped raw data export (CSV/Excel), customizable report templates (PDF/HTML), and configurable metadata fields (operator ID, sample ID, method version, ambient conditions). Audit trail functionality logs all parameter changes, calibration events, and test initiations with immutable timestamps. Optional PC-based Timepower DistilSoft™ enables advanced curve fitting (e.g., ASTM D86-to-D1160 conversion), statistical process control (SPC) charting, and LIMS integration via ASTM E1384-compliant XML export. All data files are stored in encrypted local memory with optional network backup to secure NAS or cloud repositories.
Applications
- Quality control of refinery streams including straight-run naphtha, reformate, and hydrotreated distillates
- Specification verification of automotive and aviation fuels per ASTM D439, D1655, and DEF STAN 91-91
- Boiling point distribution profiling for petrochemical feedstocks (e.g., C4–C10 cuts)
- Research-grade characterization of synthetic lubricants and bio-derived hydrocarbons
- Evaluation of volatility-related performance parameters: vapor lock tendency, warm-up enrichment, and evaporative emissions potential
- Regulatory compliance testing for EPA Tier 3 gasoline certification and EU EN 228 fuel conformity
FAQ
What distillation standards does the TP6621 support out-of-the-box?
It natively executes ASTM D86, ISO 3405, GB/T 6536, GB/T 255, GB/T 7534, and GB 3146 protocols with preloaded method parameters and validation checklists.
Can the instrument correct for barometric pressure variations during testing?
Yes—the built-in digital barometer continuously monitors ambient pressure and applies real-time corrections to all recorded temperatures per ASTM D86 Annex A1.
Is remote monitoring or network connectivity available?
Standard Ethernet and USB interfaces support local PC connection; optional Wi-Fi module and Timepower CloudLink™ enable secure remote diagnostics and firmware updates.
How is temperature calibration maintained over time?
The system includes automated self-check routines at startup; certified calibration certificates (NIST-traceable) are provided annually, and field recalibration can be performed using reference thermometers and fixed-point cells.
What safety protections are implemented during operation?
Thermal runaway prevention, overpressure venting, flame-retardant housing (UL 94 V-0), and automatic shutdown upon flask dry-out detection or coolant failure.
