Container Type Evaporative and Blending Units

The evaporative and blending units are designed for use of propane/butane in gas supply systems intended to run on natural gas in order to ensure the uninterrupted operation of burners for various purposes while reducing the volumes of natural gas supply (the peak loads reduction function) as well as to carry out the main gas supply (the reserve or emergency gas supply function). The advantage of using the evaporative and blending units is that the gas burners for propane/butane do not require adjustment.

Basic Specifications of Blending Units

  • The capacity of VDM SU/ND blending units of standard configuration varies from 150 m3/hour to 9,600 m3/hour of ready-made mixture;
  • The LPG inlet pressure is from 2 to 5 bar, while the outlet pressure is up to 500 mbar (depends on the incoming pressure);
  • The LPG outlet pressure: 10 °C above the dew point;
  • The estimated product used: a mixture of propane/butane 60/40, 112.6 mJ/cm;
  • Composition of the LPG/air mixture: 56/44%;

Basic Specifications of Evaporative Units

  • The capacity of VDM SE evaporative units with electric heating varies from 30 to 1200 kg/hour;
  • The voltage required for the operation of electric evaporators varies from 45 kW to 360 kW;
  • Liquid evaporative units feature higher output and are more cost-saving than electric ones. They are configured to produce an LPG volume of 1,200 kg/hour to 10,000 kg/hour;
  • The required water temperature is 70–90 oC;
  • The rated gas/water pressure makes 25/10 bar.
