The following section outlines the core technologies in detail:

Base oil hydrotreating is a core process for producing premium-grade lubricants. Our Hydrotreating Plants are designed to upgrade Group I base oil into higher-performance Group II base oil, enhancing key characteristics and extending lubricant service life. This critical refining step removes sulfur, nitrogen, and oxygen compounds, resulting in significantly improved oxidation stability and lubricating properties.

Key Benefits of Hydrotreated Base Oil:

  • Enhanced Lubrication Performance: The upgraded oil features improved low-temperature fluidity and a higher viscosity index (VI), ensuring superior lubrication across automotive, industrial, and high-performance applications.

  • Superior Oxidative Stability: The process dramatically increases resistance to oxidation, reducing lubricant breakdown at high temperatures and extending the lifespan of both the oil and the equipment.

  • Compliance with Modern Standards: The final product consistently meets the stringent requirements of contemporary lubricant specifications, ensuring reliable performance and enabling longer drain intervals.

Advanced Hydrotreating for Clean Fuel Production

Our Hydrotreating Plants employ state-of-the-art Hydrodesulfurization (HDS) technology to effectively remove sulfur from diesel and naphtha streams, ensuring full compliance with stringent environmental regulations, including Euro 5 standards.

  • Efficient Sulfur Removal: The HDS process uses hydrogen and a specialized catalyst to convert sulfur compounds into hydrogen sulfide (H₂S), which is subsequently separated. This achieves ultra-low sulfur levels, typically below 50 ppm, which is essential for minimizing harmful emissions.

  • Compliance with Euro 5 Standards: Our technology enables the consistent production of clean fuels that meet or exceed Euro 5 specifications, a requirement for modern engines and vehicles. This significantly reduces sulfur oxide (SOx) emissions and contributes to improved air quality.

  • Enhanced Fuel Quality: The removal of sulfur improves the combustion efficiency of diesel and naphtha, leading to cleaner exhaust, superior engine performance, and reduced particulate matter formation. This results in extended engine life and lower maintenance costs.

Hydro Reforming (Hydrocatalytic Reforming)

Hydro reforming is an advanced catalytic refining process in which hydrocarbons—typically petroleum fractions—are reacted with hydrogen under high temperature and pressure. The primary objective is to transform heavier, lower-value feedstocks into lighter, high-value products such as premium gasoline, jet fuel, and diesel.

Key Process Outcomes:

  • Converts low-octane naphtha, gasoline, or heavy hydrocarbons into high-octane reformate.

  • Removes impurities including sulfur, nitrogen, and metals.

  • Generates hydrogen as a valuable byproduct.

Isomerization: Enhancing Fuel Quality and Value

Isomerization is a catalytic refining process that transforms straight-chain hydrocarbons into their branched-chain isomers, substantially increasing the octane rating of naphtha streams. This technology is critical for manufacturing high-octane gasoline and producing valuable petrochemical feedstocks.

  • Boosts Octane Rating: The process significantly raises the octane number of naphtha, making it an essential component for formulating high-performance, low-emission gasoline.

  • Improves Fuel Efficiency: The resulting higher-octane fuel prevents engine knocking, ensures smoother combustion, and contributes to overall vehicle efficiency.

  • Generates Valuable Feedstocks: The process yields branched hydrocarbons that serve as important building blocks for various chemical applications, including polymer production and synthetic fuel manufacturing.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Aromatization: Producing High-Value Petrochemicals

Aromatization is a catalytic process that converts paraffins (straight-chain hydrocarbons) into aromatic hydrocarbons such as benzene, toluene, and xylene (BTX). This transformation significantly upgrades feedstock value by creating essential chemicals for numerous industries.

  • Produces High-Value Chemicals: Aromatics are fundamental raw materials for manufacturing plastics, synthetic fibers, solvents, pharmaceuticals, and dyes.

  • Increases Energy Density: Aromatic compounds possess higher energy density than paraffins, making them valuable as components in high-performance fuels and fuel additives.

  • Supports Petrochemical Production: The process provides critical building blocks for the petrochemical sector, enabling the synthesis of a diverse range of industrial and consumer products.
