SimDis Analyzer
Overview
Simulated Distillation (SimDis), based on Gas Chromatography (GC), is one of the most widely used analytical techniques in the petrochemical industry. A SimDis report provides valuable insight into the boiling point distribution of crude oils and petroleum fractions.
This information is crucial for refinery engineers to optimize distillation operations, improve process control, and ensure cost-effective production.
A robust and reliable SimDis Analyzer is therefore an essential tool for efficient refinery performance.
Method Compatibility
JAS SimDis Analyzers are fully configurable to meet various international standard methods for oil samples with differing final boiling points. Depending on method requirements, different columns, analytical parameters, and reference standards may be used.
Supported Methods Include:
ASTM D7096, D2887, D5307, D7398, D7213, D7169, D6352, D7500, D7900, IP 480, IP 507, IP 545, IP 601, EN 15199-1/2/3, ISO 3924, and DIN 51435.
System Configuration
UNIS 3100 HT Series
Each JAS SimDis Analyzer can be equipped with:
- UNIS 3100 HT PTV Inlet, or
- UNIS HT SimDis (CoC) with patented SimDis liner,
depending on the method’s specific requirements.
Both injectors are temperature-programmable up to 500 °C, ensuring flexibility for a wide range of samples and conditions.
Software Integration
Every JAS SimDis Analyzer is fully tested and delivered with the JAS SimDis Software Plugin, integrated with SIMDIS Expert— the most powerful and user-friendly simulated distillation data analysis software available today.
