This series of reflux drums is designed and manufactured according to pressure vessel standards such as ASME and GB/T, and the design calculations are based on reverse engineering principles considering the condenser load at the top of the column, the range of reflux ratio variations, and the proportion of non-condensable gases.
The tank body is equipped with a buffer and flow stabilization structure and a gas-liquid secondary separation component to ensure that the liquid entering the reflux pump has a stable density and low gas content.
product Advantages
More stable reflux ratio, easier to meet cutting specifications
More stable reflux pump suction
Significantly reduced reflux ratio fluctuations
Easier to consistently meet product cutting point specifications
Prevents pump cavitation, extending equipment life
By precisely calculating the minimum safe liquid level and pump suction inlet elevation, the reflux pump is ensured to operate under liquid-sealed conditions for extended periods, reducing the incidence of cavitation, vibration, and frequent pump shutdowns, significantly extending the life of the pump and seals.
Balances non-condensable gas discharge and system safety
An independent non-condensable gas discharge channel and pressure buffer are provided to prevent gas accumulation from causing artificially high liquid levels or control distortion, resulting in a more accurate and easier-to-adjust tower top control system.
Internal anti-fouling structure, reducing maintenance frequency
The large-channel internal component structure and low-retention zone design reduce the likelihood of wax buildup, scaling, and sedimentation,
significantly extending the continuous operating cycle of the reflux system.
Industry Applications
Atmospheric and vacuum distillation columns, reflux systems
Fractionation sections of hydrotreating, aromatization, and cracking units
Continuous separation systems in fine chemical processes
Benefits after implementation in these industries
