In Handbook of Liquefied Natural Gas, 2014. 10.3.5 LNG 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. On the other hand, the application to a base load LNG
Our ambient temperature gasifier series take the air through natural convection in atmosphere as heat source. It squeezes aluminum which has good heat conductivity into star-shaped finned tubes and then makes them exchange heat with cryogenic liquid to generate some gas with certain temperature without extra driving force or energy consumption. CHAPTER 52 HEAT EXCHANGERS, VAPORIZERS, 52.1.4 Air-Cooled Heat Exchangers It is sometimes economical to condense or cool hot streams inside tubes by blowing air across the tubes rather than using water or other cooling liquid. They usually consist of a horizontal bank of finned tubes with a fan at the bottom (forced draft) or top (induced draft) of the bank, as illustrated
The Advantages of Ambient Air Vaporizer:-1).No energy consumption, no pollution, environmental protection;-2).It uses special aluminium material to exchange heat and high efficiency and lightweight design to keep a long service life;the special design of 160,200 of large finned aluminium tube heat exchanger to increase the defrosting speed;The unique design of "bridge" type connection, it LNG VAPORIZER SELECTION BASED ON SITE AMBIENT Direct ambient air vaporizers are used in cryogenic services, such as in air separation plants. They are vertical heat exchanger and are designed for icing on the tube side and require defrosting. Automatic switching valves are installed to allow automatic defrosting using timers. They have been used for peak shaving plants, and smaller terminals. When compared to other vaporizer options, they require more

Ambient air heated vaporizer Natural Draft. The heat exchanger tubes are part of an all aluminium-finned extrusion. These fins provide a large surface collecting the ambient heat and as such provide energy for vaporization. Vaporizers are designed for maximum working pressure of 40 barg in compliance with EN13445 and AD2000, ASME on request.
