Low-Pressure Cooking Reactor – Bioethanol 2G – Brazil

Sector: Biochemical / Chemicals
Country: Brazil
Scope: Design, fabrication, and transport of a main reactor unit for a second-generation (2G) bioethanol plant.

Project Overview:
CITAL was selected to deliver a low-pressure cooking reactor, a core equipment unit for the pre-treatment phase in a 2G bioethanol production facility. Entirely fabricated in CITAL’s Italian workshop, the reactor plays a critical role in the hydrothermal processing of lignocellulosic biomass.

Technical Highlights:

• Type: Low-pressure cooking reactor
• Application: Pre-treatment of biomass for 2G bioethanol
• Design pressure: 1.5 barg
• Design temperature: up to 180 °C
• Material: AISI 304L / SAF2205
• Design code: ASME VIII Div. 1
• Construction site: CITAL Workshop, Italy
• Destination: Brazil

Key Strengths:

• Core technology for advanced biofuels production
• Fabricated 100% in-house under strict quality controls
• Designed for thermal stability and chemical resistance
• Conforms to international export and pressure vessel regulations
• Supports sustainable energy development through biomass valorization
