Petrochemical Solutions

The Oil & Gas industry is experiencing an important transition fueled by:

  • A continuously growing demand for petrochemicals
  • Increasingly complex crude slates paired with low refinery profit margins
  • Augmented e-mobility capabilities contrasted by a stagnant demand for transportation fuels
  • Increasing investments towards circular economy initiatives like:
    • Incentivizing the use of biofuels and bio-based co-processed feedstocks
    • Growing interest in plastic recycling for plastic waste pyrolysis oil


Such a shift calls for the repurposing of billions of dollars’ worth of existing assets, triggering new investments in both existing petrochemical manufacturing technologies, as well as innovative crude oil-to-chemical (COTC) technologies.

Our solutions at PAC provide the following benefits to our petrochemical customers:

  • Unrivalled feedstock characterization technologies improving process optimization strategies
  • Full impurity analysis of olefins in a single run increasing efficiency
  • Wide range of sulfur and nitrogen analysis methods extending catalysts lifetime
  • Chemical and physical property measurements of aromatics enabling high product quality
  • Unique trace level measurements for both lab and online instruments improving process control
  • State-of-the-art solution for distillation with industry-leading precision

The conversion of varying available feedstocks into primary building blocks and then finally to 2nd & 3rd tier chemicals our summarized in below flowchart. The colored dots represent the relevant PAC solutions.

The process flow chart shows the selected pathways for the manufacturing of leading petrochemical products by various building blocks derived from broad range of different feedstocks. The PAC solutions for those streams are represented with dots and explained below in the legend table

PAC has a broad product portfolio for petrochemical industry. Our solutions cover both physical property and chemical analysis measurement needs ranging from lab to process. The available solutions are outlined below:

With broad product portfolio, PAC offers sets of solutions for the analysis of olefins, aromatics, various derivatives as well as of the emerging feedstocks.

  • Meet sulfur regulations and control your process with continuous measurements
  • Achieve precise measurements with correlation to primary test methods
  • Wide range of samples
  • User-friendly and easy maintenance


Olefin Purity Analyzer

ASTM D6159, D8098, D2163, D2504, D2505, D2712, D5504, D7423

Olefin Purity Analyzer combines four channels in two GC’s, which can operate in parallel to analyze low levels of hydrocarbons, oxygenates, sulfur components, trace gases in just one run.

It performs ethylene and propylene analysis according to D5234 and D5273 product specifications and solves measurement challenges like:

Key Advantages

  • Absorbance of active components, by having a fully inert sample path
  • Interferences from air with specially designed valve enclosures purged with Helium carrier gas to prevent air diffusion and improve detection limits
  • Low concentration measurement with high sensitivity detectors like HID & SCD
  • Issues due to co-elution’s of HC components with sulphur components are overcome by using an SCD over PFPD, where the SCD has a better linearity, higher selectivity and an improved stability over previous generations of SCD’s



ASTM D5504, D5623, D7011, D7807

SeNse offers best in market performance for high return on investment for GC applications to determine sulfur species in hydrocarbon matrices.
