Design and thermal analysis of ambient air vaporizers

  • How do ambient vaporizers work?

    Ambient Vaporizers vaporize liquified gas by using heat absorbed from the ambient air.
    ACME Cryogenics offers a variety of ambient air vaporizers for a number of applications.
    These ambient air vaporizers are sized to match your flow requirement to avoid low-temperature gas entering the product pipeline..

  • What is ambient air vaporizer?

    Ambient air vaporizers (AAV) are well known and are used in many cryogenic liquid plants to vaporize cryogenic liquids, such as liquid nitrogen.
    Typically, AAV heating duty is relatively small in these plants, which are not a limiting factor for the plot plan..

  • What is the heat transfer coefficient of an ambient vaporizer?

    The average value of overall heat transfer coefficient comes out to be 9.95 W/m.

    1. K [6].
      2. Applying basic heat balance equation as in equation (1), area required by vaporizer to deliver desired flow rate is determined.
      The mass flow rate ��̇ to be vaporized is 0.17 kg/s.

  • What is the temperature of the ambient vaporizer approach?

    Standard Features.
    Large models available upon request. *Nominal flow rate is based upon 8 hours continuous service between defrosts, an ambient temperature of 50\xb.

    1. F, relative humidity of 50%, and a 20\xb
    2. F approach temperature

  • What materials are used in ambient vaporizers?

    Material: All Aluminium or Aluminium with Stainless Steel Lining.
    Usage/Application: Ambient Air Natural Draft Pressure Building Cryogenic Vaporization..

  • Cryogenic vaporizers are used to convert Cryogenic liquids and low-temperature fluids into gaseous state by heating and/or vaporization.
    They work as heat exchangers that transform these liquefied gases into warm gaseous products.
  • The average value of overall heat transfer coefficient comes out to be 9.95 W/m.
    1. K [6].
      2. Applying basic heat balance equation as in equation (1), area required by vaporizer to deliver desired flow rate is determined.
      The mass flow rate ��̇ to be vaporized is 0.17 kg/s.
Present research focuses on experimental set-up design and investigating effects of flow rate and ground clearance on the performance of ambient air vaporizers.

Does flow rate and ground clearance affect ambient air vaporizer performance?

An experimental set-up has been designed and effects of flow rate and ground clearance on the performance of ambient air vaporizers are evaluated

The flow rate is increased from the rated capacity of 500 Nm³/h to 640 Nm³/h and ground clearance is reduced from 500 mm to 175 mm

What is ambient air vaporizer (AAV)?

LNG ambient air vaporizer (AAV) utilizes ambient air as the heat source with zero energy consumption, hence is widely used in gas stations [2, 3]

The vaporization efficiency of AAV depends on the heat transfer performance of AAV finned tube bundle, which greatly affects the stable and effective operation of LNG gas station

What is vaporizer model?

2

Ambient air vaporizer model The numerical model of the vaporizer calculate LNG temperature profile in fin tube of AAV, the thickness and density of frost layer on the tube surface and water-vapor in the air stream which flows outside
