Raffinate

Description

🌟 Comprehensive Introduction to Nouri and Buali Petrochemicals Raffinate (Nouri and Buali Raffinate)

Presented by Alkimia, the official supplier of petrochemical products from Iran

🔍 What is Raffinate and Why is it Important?

Raffinate is a light hydrocarbon fraction derived from refining streams rich in aromatic compounds. After the removal of aromatics such as benzene, toluene, and xylenes, the remaining by-product—raffinate—retains high economic and industrial value.

Depending on its composition, raffinate can contain a high percentage of paraffins (up to 92%), a specific amount of naphthenics, and a small percentage of olefins and aromatics. This unique composition makes raffinate a widely used material in the fuel and petrochemical industries, as well as in gasoline blending formulations.

📊 Technical Specifications of Nouri Petrochemical Raffinate (Based on Latest Analysis)

⚙️ Technical Interpretation of Key Properties

• High Reid Vapor Pressure (RVP) indicates high volatility, which is important for gasoline blending.
• A wide boiling point range (32°C to 125°C) allows multipurpose use as feedstock or fuel.
• Low density improves performance as a light fuel.
• Extremely low sulfur content (less than 5 ppm) meets global environmental standards.
• n octane number below 75 limits its use in premium fuels but makes it suitable for blending with octane boosters.
  

  Bouali Sina Petrochemical Raffinate — Technical Overview and Product Analysis

  At Bouali Sina Petrochemical Company, raffinate is generated as a high-value light hydrocarbon product widely used in fuel blending and petrochemical downstream applications.

  In simple technical terms, raffinate represents the non-aromatic fraction remaining after removal of Benzene, Toluene, and Xylenes (BTX). Due to its high paraffinic composition and very low sulfur level, it is considered a strategic blending and processing feedstock in modern refineries.

  Detailed Technical Interpretation of Raffinate Analysis

  ✅ Saybolt Color (+18 Minimum)

  The Saybolt color index measures visual purity and hydrocarbon cleanliness.

  A value of +18 indicates:

  ✔ Excellent refining quality
  ✔ Minimal heavy aromatic contamination
  ✔ High suitability for gasoline blending operations

  Higher Saybolt values generally reflect superior processing control in aromatics units.

  ---

  ✅ Density (650–740 kg/m³)

  This density range classifies the product as a light hydrocarbon stream, similar to Light Naphtha fractions.

  Engineering advantages include:

  ✔ Improved combustion efficiency
  ✔ Enhanced octane blending capability
  ✔ Optimized vaporization behavior in fuel systems

  ---

  ✅ Boiling Range (30–130°C)

  The distillation range is one of the most critical performance indicators.

  This boiling window confirms:

  ✔ Compatibility with gasoline pool blending
  ✔ Suitability as petrochemical cracking feedstock
  ✔ Excellent cold-start fuel behavior

  Low initial boiling point contributes to rapid ignition characteristics.

  ---

  ✅ Lead Content (≤5 ppb)

  The extremely low lead content demonstrates:

  ✔ Compliance with modern environmental regulations
  ✔ Export suitability for international markets
  ✔ Safe usage in catalytic refining processes

  Lead-free streams are essential for protecting downstream catalysts.

  ---

  ✅ Olefins Content (≤14 wt%)

  Olefins are chemically reactive hydrocarbons.

  Controlled olefin concentration provides:

  ✔ Better storage stability
  ✔ Reduced gum formation
  ✔ Improved oxidation resistance

  This balance is highly valued in refinery blending strategies.

  ---

  ✅ Paraffins Content (≥70 wt%)

  High paraffin concentration is the most significant strength of Bouali Sina raffinate.

  Technical benefits include:

  ✔ Excellent gasoline blending component
  ✔ Ideal feed for isomerization units
  ✔ High-quality alkylation feedstock potential
  ✔ Stable combustion characteristics

  From a refinery engineering perspective, high paraffinic composition significantly increases commercial value.

  ---

  ✅ Reid Vapor Pressure — RVP (≤11 psi)

  RVP determines fuel volatility behavior.

  Controlled vapor pressure ensures:

  ✔ Safe storage and transportation
  ✔ Reduced evaporative losses
  ✔ Compliance with gasoline volatility standards

  ---

  ✅ Ultra-Low Sulfur Content (≤1.5 ppm)

  The sulfur level is exceptionally low compared to many regional raffinate streams.

  Key advantages:

  ✔ Reduced SOx emissions
  ✔ Catalyst protection in downstream units
  ✔ Compliance with modern clean-fuel standards
  ✔ Premium export acceptance

  Low sulfur content is widely considered a major competitive advantage.
