The feed material is pumped into the system and passes through a filter unit, ensuring no solid impurities or particles can damage the membrane. Once filtered, the raw material is preheated using a heat exchanger, which recycles energy from the dehydrated product to improve overall efficiency.
The preheated raw material enters an evaporator, where it is heated to form vapor. This step ensures the mixture reaches the optimal state for separation, typically between 60°C and 150°C, depending on the material type and water content.
The vaporized feed flows into the membrane module system, the heart of the technology. Here’s what happens:
The dry vapor exits the membrane module and enters a cooling system. Using condensers, the vapor is cooled back into a liquid state. This high-purity dehydrated product, now free of excess water, is collected in a storage tank, meeting industrial standards (e.g. water content below 0.5%).
Water molecules that permeate through the membrane are collected via a vacuum condensation system. These water molecules are condensed and discharged into a permeate tank, ensuring proper separation and enabling environmentally sound wastewater management.
The entire process is PLC-controlled for precision and safety. Real-time monitoring of parameters such as temperature, pressure, and flow ensures smooth operation. This level of automation minimizes manual intervention and enhances efficiency.
The process incorporates heat recovery systems, recycling heat from the dehydrated product to preheat the incoming feed. This significantly reduces overall energy consumption, making the system not only efficient but also cost-effective for long-term operations.
Damo’s pervaporation membrane process is a clear step forward for industries requiring high-purity organic solvents and acids while reducing operational costs and environmental impact.
