Real-time AI crude quality monitoring strengthen CDU optimisation Oil Analysis


MODCON Systems believes crude distillation is the foundational operation of petroleum refi ning, separating crude oil into fractions based on boiling ranges. As refi ners increasingly process diverse and unconventional feedstocks, fl uctuations in crude composition have become a central challenge affecting yield stability, energy effi ciency and product quality. These variations are particularly disruptive during crude switching, when rapid changes in boiling behaviour and separability can destabilise column profi les.


To address this complexity, advanced optimisation methodologies incorporating deep reinforcement learning (DRL) are gaining momentum. Unlike traditional modelling approaches that rely heavily on historical datasets, DRL operates through iterative interaction with the process environment. The system evaluates different control actions, receives performance-based rewards and gradually identifi es optimal strategies for targeted objectives such as maximising distillate yield or minimising furnace duty. DRL’s ability to adapt in real time makes it well


suited for dynamic refi nery processes.


However, DRL’s effectiveness depends on access to accurate and current process measurements. Without real-time information on crude properties, model decisions may refl ect statistical artifacts rather than true operational needs. This underscores the importance of integrating continuous crude quality analysis into AI-driven control frameworks. Near-infrared (NIR) analytical technologies, such as the MOD-4100 Crude Oil Analyser, provide immediate characterisation of key crude parameters, including composition and viscosity. These measurements feed directly into optimisation systems such as the MODCON.AI CDU Optimisation Suite, enabling continuous adjustment of operating setpoints based on actual feed properties. The AI model replicates complex distillation relationships and aligns column behaviour with the crude’s true characteristics, signifi cantly improving stability during feed transitions.

Safeguard Catalyst Performance and Save Millions with High-Precision, ppb-Level Detection


catalysts and maintain purity across your petrochemical streams.


Our GC’s equipped with SeNSe² detectors are fully compliant and application-ready for key ASTM methods, including ASTM D5623 (sulphur compounds in light petroleum liquids), ASTM D5504 (ultra-trace sulphur in natural gas and gaseous fuels), and ASTM D7011 (trace thiophene in refi ned benzene).


Whether analysing light liquids, gaseous fuels, or complex feedstocks, SeNSe² ensures accurate, repeatable results, even under the toughest analytical conditions.


In petrochemical, refi ning, and natural gas laboratories, even trace levels of sulphur and nitrogen compounds can cause big problems, poisoning catalysts, degrading product purity, and putting compliance at risk. But many sulphur chemiluminescence detectors (SCDs) demand frequent recalibration and ongoing maintenance just to stay accurate.


PAC, powered by AC’s SeNSe² for gas chromatography (GC), changes that. Built for long-term stability and precision, this advanced sulphur and nitrogen detector combines day-over-day reliability, true equimolar response, and ppb-level sensitivity, so you can focus on results, not recalibration.


Sulfur and nitrogen detection isn’t just about measurement; it’s about protecting multi-million-dollar assets. Catalyst deactivation caused by trace contaminants can disrupt entire operations. SeNSe² provides the confi dence needed to safeguard


With a built-in G-Cal validation module, automated leak checks, and touchscreen diagnostics, SeNSe² minimises downtime and simplifi es upkeep. Its modular design integrates seamlessly into GC platforms, making it the smart upgrade for any lab ready to boost reliability without overhauling existing systems.


We’ve compiled our latest SeNSe² application notes into one concise 1-pager, showcasing real-world data and proven performance across critical applications, like sulphur in light liquids, COS in propylene, and thiophene in benzene.


See how SeNSe² meets today’s tightest sulphur and nitrogen specifi cations while delivering stability, selectivity, and equimolar accuracy that lasts.

Oxidation Stability Across Fuel Types, Feedstocks, and Biofuel Content with RapidOxy 100 Fuel


Ensuring oxidation stability is critical across all fuel types – from fossil diesel to renewable blends – but traditional test methods can be slow, inconsistent, and diffi cult to apply across diverse compositions. Anton Paar’s RapidOxy 100 Fuel offers a fast, standardised, and fully automated solution for measuring induction periods across a range of fuel types.


Based on the Rapid Small Scale Oxidation Test (RSSOT), Anton Paar’s RapidOxy 100 Fuel determines oxidation stability in diesel and spark ignition fuels by measuring the induction period (IP) for fuels ranging from B0 to B100 diesel and all gasoline types. It is the only automated RSSOT instrument compliant with EN 16091, ASTM D7545, and ASTM D7525, and is offi cially accepted as a faster alternative to both EN 15751 and ASTM D525.


A key advantage of the RSSOT method is its versatility. Using small sample volumes (5 mL) and precise temperature and pressure control, Anton Paar’s RapidOxy 100 Fuel enables fully automated testing with results in just 31 minutes for gasoline, up to eight times faster than ASTM D525. (For diesel fuels, it delivers results in 60 minutes – 20 times faster than EN 15751.)


In addition to shorter test times (31 vs. 240 minutes), RSSOT applies a consistent break point defi nition (10% pressure drop), enabling reliable results even when ASTM D525 fails to trigger. RapidOxy 100 Fuel eliminates the need for a burst disk and includes built-in safety features such as automatic overpressure shutoff and a locking safety hood.


continue to rise, the integration of AI with real-time analytical measurement provides a forward-looking solution for refi neries seeking to maintain consistent product quality and optimise overall performance.

The versatility of RapidOxy 100 Fuel extends to renewable fuels such as hydrotreated vegetable oil (HVO) and gas-to-liquid (GTL), which have recently gained approval for commercial use worldwide. As with fossil- based fuels, these alternatives must meet the same specifi cations, including requirements for oxidation stability. In a repeatability study of the RSSOT method using HVO and GTL, four consecutive tests per fuel showed maximum deviations of just 2.65 minutes (HVO), well within the limits defi ned by EN 16091. This confi rms RSSOT as a reliable tool not just for fossil fuels, but also for new- generation renewable alternatives.


Anton Paar’s RapidOxy 100 Fuel delivers rapid, reliable, and repeatable oxidation stability testing across a range of fuel types. Fully compliant with international standards and engineered for lab safety and effi ciency, it streamlines workfl ows and accelerates product development and release.
