Customized petrochemical distillation equipment
Petrochemical distillation equipment is crucial for refining crude oil into usable products like gasoline, diesel, and other fuels. However, crude oils vary greatly in terms of their chemical composition, and one-size-fits-all solutions simply won’t do. This is where customized petrochemical distillation equipment comes in. Let’s dive into why customization is key and how it ensures optimal performance, yield, and return on investment (ROI) for your refinery.
Why Customization Matters
Crude oil isn’t one-size-fits-all. Variations in properties like API gravity, sulfur content, and wax/acid content demand tailored distillation systems. Here’s why customization plays such a significant role in refining crude oil:
Crude oil properties vary dramatically:
API Gravity
- Light Crude (API >31.1): Light crudes require precise fractionation to maximize the yield of valuable products such as gasoline and diesel.
- Heavy Crude (API <22.3): On the other hand, heavy crudes are thicker and more viscous, requiring specialized heating systems to facilitate proper distillation.
Sulfur Content
- Sweet Crude (<0.5% sulfur): This type of crude is low in sulfur, which means standard carbon steel metallurgy is sufficient.
- Sour Crude (>0.5% sulfur): Crudes with higher sulfur content require corrosion-resistant materials like 316L stainless steel to prevent damage to the equipment.
Wax and Acid Content
- High-Wax Crude: Crude oils with high wax content require integrated dewaxing units to avoid blockages and to ensure smooth distillation.
- High-Acid Crude (TAN >1): These crudes need specialized materials to resist corrosion from naphthenic acids.
Understanding Crude Oil Variations
To better understand how these factors influence distillation, it’s important to distinguish between different crude types.
Light Crude vs. Heavy Crude
Light crude oil has a lower viscosity and is easier to process. On the flip side, heavy crude oil is thicker and requires more advanced equipment to break down. Custom distillation equipment can ensure that the right heating systems and fractionation methods are applied for optimal results.
Sweet vs. Sour Crude
Sweet crude is generally more stable and easier to process than sour crude, which has a higher sulfur content. Sour crude requires corrosion-resistant alloys and more intricate distillation equipment to ensure longevity and efficiency.
High-Wax vs. High-Acid Crude
Wax can cause clogging and slow down the distillation process. High-acid crude can lead to corrosion in standard equipment, requiring additional measures like specialized materials and systems to prevent this.
To illustrate how these factors influence distillation, let’s look at three major crude oil types from China:
Each of these crudes would need different equipment and processes, emphasizing the importance of customization.
| Crude Type | API Gravity | Sulfur (%) | Wax Content (%) | TAN (mg KOH/g) |
|---|---|---|---|---|
| Daqing | 33.4 | 0.10 | 26.2 | 0.05 |
| Shengli | 24.8 | 0.80 | 16.5 | 1.80 |
| Tarim | 42.5 | 0.03 | 4.2 | 0.12 |
The design of customized petrochemical distillation equipment begins with a data-driven approach. Here’s how we tailor the solution to your specific needs:
Data-Driven Approach
By sharing your crude oil analysis report or sending in samples, our engineers conduct three-stage lab tests. These tests map key variables like viscosity, boiling curves, and impurity profiles, ensuring we understand your feedstock inside and out.
Tailored Configuration
- Pre-treatment Options: Depending on the crude’s impurities, we may include dehydration, desalting, or dewaxing units.
- Heating Systems: For light crudes, tubular furnaces work well, while molten salt heaters are perfect for heat-sensitive heavy crudes.
- Fractionation: Column internals are customized to optimize yield and ensure that valuable cuts like 150SN/350SN base oils are targeted.
Precision Engineering in Custom Systems
Precision engineering is a key factor in ensuring that your distillation equipment meets the demands of your crude oil. Here are a few examples of custom solutions:
Heat Exchangers
We offer shell-and-tube heat exchangers for high-pressure environments and air-cooled units for water-scarce areas.
Pumps
Pumps are specially designed to handle corrosive or abrasive feeds, ensuring the durability of your system even in harsh conditions.
Customized petrochemical distillation equipment has several advantages over generic systems:
Yield Optimization
Custom systems achieve a 2-5% higher base oil recovery by tailoring the fractionation process to your crude’s API.
Quality Compliance
Our systems meet strict quality standards like ISO 4406 and DOE specifications for sulfur content and viscosity index.
Energy Efficiency
Molten salt heating systems can reduce fuel costs by 15-20% compared to conventional heating methods.
Benefits of Customized Equipment
Investing in customized distillation equipment isn’t just about meeting your crude oil’s unique needs – it also brings long-term benefits such as:
- Maximized output
- Improved efficiency
- Reduced maintenance costs
- Long-lasting equipment
