Supersonic In-Line Stripping -
Designed for use in batch or continuous operation, our proprietary supersonic in-line nitrogen stripping system utilizes low-velocity supersonic two-phase flow principles to disperse nitrogen gas streams with shockwaves. It creates extremely fine nitrogen bubbles, resulting in a maximum mass transfer surface area. This system quickly offsets a low capital investment, decreasing processing costs through the efficient use of nitrogen.
Installed easily and directly into your process piping, our in-line system allows convenient single-stage nitrogen stripping of process fluids as they are off-loaded into your storage tanks or transferred from one chemical processing phase to another. Multiple in-line systems, installed along the same line, can minimize stripping time.
Batch Stripping -
In batch operations, Rivoira's supersonic in-line system is used with a recycle loop. Adjusting the recycle and nitrogen flow rates reduces undesirable components in batch reaction vessels and storage tanks to any level required.
Alternative batch stripping devices like gas spargers and porous, sintered metal plates are relatively simple in design and operation but are not as efficient as Rivoira's system. Compared to sparging, our in-line system reduces stripping time by up to 90%.
Multi-Stage Column Stripping -
For applications requiring extremely low contaminant levels, our proprietary multi-stage column stripping system offers optimal processing efficiency. For example, a water stream with oxygen strips down to 5 parts per billion level in a single pass. Less than 20 liters to more than 2.000 liters of water per minute can be treated using the least amount of Nitrogen possible, allowing substantial savings in gas consumption costs. Superior operating performance is obtained over bubbling columns.
Other Stripping Methods for Special Situations -
Processors can face operating and equipment constraints that necessitate the use of specialized methods like nitrogen or vacuum stripping, or pipe sparging. When confronted with a unique problem, we can assist you in designing a stripping method that satisfies your particular situation.
