LNG (Liquid Natural Gas) station equipment

LNG, or Liquid Natural Gas, is produced by purifying and cooling natural gas to a temperature of -162°C, transforming it into a liquid for storage. It is then regasified for use. In LNG regasification stations, typical equipment includes LNG cryogenic storage tanks, LNG unloading and pressurization equipment, ambient vaporizers, heaters (BOG, EAG heaters), natural gas reheaters, and pressure regulation and metering odorizing devices.

LNG Unloading and Pressurization Equipment

LNG unloading and pressurization equipment integrates components such as low-temperature metal hoses, pressurization vaporizers, low-temperature pipelines, and low-temperature valves. Its function is to vaporize LNG through ambient vaporizers, returning the vaporized natural gas back to LNG tankers, thereby increasing the pressure within the storage tank. This ensures a continuous output of LNG from the tank, maintaining the continuous and stable operation of the gas supply system. The equipment combines vaporization, pressure stabilization, control, and safety interlock functions into one, featuring a skid-mounted structure for easy installation, operation, and maintenance.

Ambient Vaporizer

The LNG Ambient Vaporizer is a specialized equipment that utilizes ambient temperature to vaporize LNG (or LPG). It is constructed with star-shaped fin tubes, offering features such as simple operation, strong vaporization capability, rapid defrosting of frost on fins, low investment, and low operating costs.

In station design, it's common to use no fewer than two ambient vaporizers, and the total vaporization capacity of ambient vaporizers should be determined as 1.5 times the peak hourly flow rate for general use. However, for industrial users, it should be determined as 2 times the peak hourly flow rate.
