1. Initial Conditions – Specific Requirements for Pressure Equipment
The customer from the chemical industry needed a custom-designed pressure vessel for installation in an environment with a risk of explosion. Additionally, an unconventional mixing solution and an integrated filtration element for filtering the stirred suspension were required.
A special double-jacketed vessel design was proposed to allow precise control of process temperature via steam heating. The production environment imposed strict demands on safety, materials used, and manufacturing precision.
2. Technological Solution Delivered by ENVITES
ENVITES provided the complete design and delivery of a turnkey solution including:
• Technical design based on customer specifications
• Structural calculations of the pressure vessel
• Preparation of manufacturing documentation
• Fabrication of the vessel from stainless steel
• Pressure testing
• Final on-site installation
Equipment Specifications:
• Entire construction including mixing components made of stainless steel
• Designed for installation in an EX-zone
• Maximum operating pressure: 5 bar
• Heating integrated into the process – steam is supplied into the jacket to heat the vessel interior
• Special type of agitator – a slow-speed agitator combining rotational and axial motion, equipped with a special pressure mechanical seal
• Equipped with sensors for process measurement and control
• Integrated filtration – using a ceramic filter directly inside the pressure vessel
3. Results and Benefits of the Solution
• Complete turnkey solution from design to installation
• Safe operation in explosive atmospheres (EX zone)
• Highly efficient mixing due to dual-axis motion of the agitator
• Final product filtration without the need for external equipment
• High-quality stainless steel construction resistant to chemical exposure
Summary
ENVITES demonstrated the ability to flexibly respond to specific customer requirements in the chemical industry and deliver a comprehensive technological solution meeting stringent safety and operational demands.
The result was a custom-designed agitated pressure vessel with integrated filtration, specifically intended for explosive environments – designed, manufactured, and installed as a turnkey project. The equipment is conceived as a multifunctional unit that ensures the necessary chemical, mechanical, and safety parameters for the production of a special chemical suspension.
Several innovative solutions were applied to increase production capacity, enhance efficiency, and optimize functionality of the system.
