1500m3 Rim Mounted Biogas Holder Balloon With PVDF Membrane For Biogas Plant
Our double membrane gas holders provide efficient storage volume directly on top of tank walls. This innovative design maximizes space utilization without requiring additional ground-level infrastructure, offering significant investment savings by eliminating the need for traditional pressure-retaining tank roofs and separate concrete bases.
The integration of gas holders into existing tank structures reduces construction costs and installation time, crucial for projects with tight deadlines. This approach enhances operational efficiency by consolidating maintenance access points into a single structure.
The 1500m³ tank rim-mounted biogas holder with PVDF membrane can be installed on both concrete and steel tanks, provided the tank design accommodates the imposed forces. Thorough structural analysis ensures the integrity of both components during operation, offering flexibility for various project requirements.
The system features two membranes anchored to the tank wall top, with gas containment between the inner membrane and tank shell. The outer membrane is permanently air-supported. Containment volumes adapt to requirements, with structure height determined by volume needs and tank diameter. As gas volume decreases, the inner membrane floats on the tank's liquid contents.
More complex configurations may include a central support column and supporting underbelts spanning to the tank wall to support the inner membrane when containment is depleted.
