Are you an engineer or a purchasing manager in a chemical plant or pharmaceutical factory? Are you looking for a reliable and efficient solution for ethanol dehydration? The Damo PV Membrane is designed to meet your needs, offering significant cost savings, reduced energy consumption, and a sustainable approach to ethanol dehydration.
The Damo PV Membrane is a state-of-the-art solution for 200 LPH Ethanol Dehydration. It efficiently separates water from ethanol, resulting in a product with less than 1% water content. This technology is energy-efficient, environmentally friendly, safe, simple to operate, and designed for continuous, round-the-clock operation.
In this guide, we will delve into the technical aspects of the Damo PV Membrane, highlighting its operational parameters, technological advantages, and why it stands out as the ultimate solution for ethanol dehydration in your facility.
Technology Introduction
The Damo PV Membrane employs inorganic pervaporation technology, a process that effectively separates water from organic solvents through surface-adsorption and molecular-sieving mechanisms. The pore size of the permeation membrane (0.4 nm) is strategically designed to be between the molecular size of water and organic solvents, allowing for efficient water removal from the ethanol solution.
Operational Excellence and Energy Efficiency
The Damo PV Membrane operates at a temperature range of 100-140℃ and a pressure range of 0.1-0.3 MPa, ensuring optimal performance. One of its standout features is its energy efficiency. For every ton of solvent solution processed, it commonly consumes less than 0.5 tons of steam. This translates to significant savings on energy costs for your facility.
Environmental and Safety Benefits
The Damo PV Membrane is designed with environmental sustainability in mind. Unlike traditional methods, it does not require the introduction of other components for azeotropic dehydration systems. The process is controlled automatically and monitored online through a PLC and HMI, ensuring safety and simplicity.
Simplified Installation and Compact Design
The equipment is modular and has a small footprint. This compact design allows for easy integration into existing systems, minimizing the need for extensive site preparation and reducing installation costs.

Feed Conditions
The pH of raw material is in the range of 6.5 to 8.5 (In fact, the maximum range can be PH2.0-8.5). The conductivity of raw material is less than 5 μS/cm. In addition, without of polymer, salts, saccharides, solid particles, acidity, alkalinity etc, which will damage permeation membrane in the raw material.
Technical Process Description
Raw Material Transport: The ethanol solution is precisely transported to a filter (with a pore size of around 0.1 μm) by a pump.
Preheating: The filtered material is preheated in a heat exchanger to recycle the heat from the dehydrated product.
Evaporation: Subsequently, the material is vaporized in the evaporator by steam.
Separation: The vaporized material flows into the membrane separators for dehydration. In this project, there are five membrane separators arranged in series.
Water Removal: The water molecules selectively permeate through the membrane under a pressure difference and are collected in a storage tank by the cooled condenser.
Water Transport: The collected water is then transported to the next process by a pump.
Product Cooling and Storage: The product produced by the membrane is cooled and collected in a storage tank.
Product Transport: The cooled and collected product is transported to the next process by a pump.
