Are there any companies working on LNG gasification plants?

The current vaporization and pressure regulation station seems to have a clear function: vaporization, pressure regulation, and metering. However, the vaporizers must be operated in a one-in-use-one-backup configuration, as the problem of frosting on these vaporizers is severe; they need to be replaced every 8 hours on average. Is there any way to reduce frosting in the carburetor?

Is this imported? When water is heated, doesn’t it freeze?
The company has filed a patent for this technology; details can be found at: http://www.freepatentsonline.com/6283068.pdf. 1. Heating water certainly requires energy, and standard water-bath heat exchangers are equipped with electric heating elements. 2. Cost issue: The cost of a single set of such vaporizers is certainly higher than that of ordinary vaporizers, but they can operate continuously for 24 hours without the need to alternate between a vaporizer in use and one used for defrosting (their vaporization capacity is significantly higher, as hot water is used for heating inside). For users, purchasing only a small number of these devices is sufficient to achieve the same production capacity, with less space required as well. 3. Such equipment certainly requires a water source and power supply, but it can make use of locally available abundant water sources; heating methods such as solar water heaters can also be considered.
1. Before the inlet of the standalone water-bath heat exchanger, the material is first vaporized in a vaporizer; thus, the water bath serves as an auxiliary heating element. The power capacity of such units is generally around 40 KW, and they are installed at the inlet of the vaporizer. Due to the low temperature there, a high level of electric heating power is required. 2. The efficiency of the vaporizer results in the temperature of the NG passing through it being about 10°C lower than the ambient temperature; therefore, it is not suitable for use in winter. A water bath heat exchanger is still necessary, and the fins will frost over. Unless the temperature of the medium is kept above 0°C all year round, the vaporizer functions as a radiator in winter. 3. It is not practical to use natural energy sources such as solar energy to heat water. The water temperature in the water bath heat exchanger I am using now needs to be maintained at 60–70°C in winter, and solar energy is practically ineffective during winter.
You can divert a stream of natural gas from the regenerator outlet to the main gasifier inlet for defrosting, which can speed up the natural defrosting process
