Product Description

Design of 1,000-100,000 Liter/Hour Single-Stage Reverse Osmosis Systems for Refineries 


1. Background Requirements:


Oil refineries are high water consuming industries and are used for cooling, boiler make-up, and process reactions. Because the raw water may contain suspended solids, salts, oils and organic contaminants leading to equipment fouling, corrosion and loss of efficiency. The single-stage reverse osmosis system effectively removes 97%~99% of dissolved salts and impurities through physical filtration to provide stable, high-purity water to meet the stringent water quality requirements of the oil refining process.


2. Overall Design

  • Continuous and stable water production
  • Water production capacity: 1-100,000 L/H
  • Inlet water standard: conductivity ≤ 2000 μS/cm
  • Energy-saving: Low energy consumption design with China Energy Efficiency Commission labeling
  • Adaptability: Compatible with complex raw water conditions in refineries (oil, high salt, fluctuating water quality).


3. System Composition


3.1 Pre-treatment System

  • Multi-media filter: remove suspended solids, rust, colloid (precision 10-20 μm).
  • Activated carbon filter: adsorb oil, organic matter and residual chlorine (to protect RO membrane from oxidation).
  • Water softening filter/Dosing device: reduce water hardness and prevent scaling
  • Precision security filter: 5 μm filter element intercepts small particles to ensure that the feed water SDI ≤ 5.


3.2 Reverse Osmosis Host

  • Membrane module: choose anti-pollution rolled composite membrane or low-pressure composite membrane. Single membrane water production 1.5m³/h, according to the site conditions combined with the realization of high efficiency capacity.
  • High-pressure pump: frequency control stainless steel high-efficiency centrifugal pump (pressure 0.6 ~ 1.5 MPa)
  • Desalination rate: ≥98
  • Conductivity of produced water ≤50 μS/cm.
  • Recovery rate: 60%~75% (adjusted according to the salinity of raw water to reduce the discharge of concentrated water).


3.3 Post-treatment System and Intelligent Control

  • PH adjustment
  • PLC control system for real-time monitoring of pressure, flow, conductivity, automatic flushing and alarm.
  • Data remote access to support integration with refinery DCS system to achieve centralized management.


4. Daily Maintenance

  • Record pressure and conductivity data daily.
  • Monthly cleaning of pretreatment filter media, checking the sealing.
  • Chemically clean RO membrane (citric acid + NaOH) every 3~6 months.
  • Usually replace RO membrane every 3 years
  • Backup pumps and membrane housings are prepared to ensure quick switchover in case of failure.
