Who has the detailed process flow of LNG production?

Process. 1. The LNG is transported to the gasification station by the tanker, and the LNG unloading supercharger is used to increase the pressure in the tanker, and the LNG in the tanker is sent to the LNG cryogenic storage tank for storage.

2. When discharged from the LNG storage tank, the pressure of the storage tank is increased through the self-pressurization system of the storage tank, and then the liquid phase outlet valve of the storage tank is opened, and the LNG in the storage tank is sent to the gasifier through the pressure difference, and then sent to the municipal gas pipeline network through the processes of pressure regulation, metering, and odorization.

3. When the outdoor ambient temperature is low and the natural gas temperature at the outlet of the air-temperature gasifier is lower than 5, a water bath heater needs to be connected in series at the outlet of the air-temperature gasifier to heat the gasified natural gas.

Personally, I think it's such a difference, and I hope it will help you.

Production technology: mainly in order to coordinate the rational use of effective resources and related production technologies, the manufacturing industry has prepared a special program for the technical aspects to ensure that it can better play a good guiding role in the production process.

Produce craft is a method and process in which workers use production tools to carry out value-added processing or treatment of various raw materials and semi-finished products, and finally make them into finished products.

Technological process: The process of arranging each process from raw materials to finished products, with two or more business steps to complete a complete business behavior, can be called a process; Note that there are two or more business steps.

The process is that the natural gas is compressed, decarburized, dehydrocarbonized, dehydrocarbonized, debenzened, debenzene, and dusted, and loaded into a cold box.

Compression>Decarburization", Dehydration, Debenzene, Liquefaction, products.

How LNG refueling station works:

The liquefied natural gas in the LNG storage tank is pressurized through the filling skid, and sent to the filling machine to be filled into the LNG gas storage cylinder of the vehicle to complete the entire filling work.

First of all, the gas phase port of the storage tank is connected to the lower inlet (outlet) liquid port of the tanker with a metal hose (all the back is represented by the lower liquid inlet), slowly open the gas phase valve of the storage tank and the lower liquid inlet valve of the tanker, and then start flat pressure through the station control operating system, so that the gas in the storage tank can enter the tanker from the gas phase outlet through the lower inlet port of the tanker, so that the gas can be fully cooled, and the gas in the tank can be completely improved, so as to achieve the pressure in the storage tank to the minimum, and the pressure in the tank and the tanker can be flattened to the bottom under normal circumstances.

After the tank is flattened, the tanker self-pressurization begins, firstly, the tanker gas phase port and the tanker lower inlet end of the metal hose at the tanker inlet are removed, and connected to the self-pressurized gas phase port of the tanker, and then the metal hose is connected to the inlet port of the vaporizer from the self-pressurized liquid phase port of the tanker (the self-pressurization of the storage tank and the self-pressurization of the tanker are completed by the same vaporizer, and the pipeline is also the same, but it is cut off and controlled by the corresponding valve). The liquid phase port and gas phase port valves of the tanker are slowly opened, and then the pressurization starts through the station control system, and the tanker is pressurized to higher than the pressure of the storage tank to start unloading, and the maximum pressure should be lower than the starting pressure of the tanker safety valve.

2.Pre-cooling cycle and dosing:

When the interval between two dosing is more than half an hour, the liquefied natural gas in the pipeline has been gasified, in this case, it is necessary to carry out pipeline circulation pre-cooling to ensure that the high-temperature gas will not enter the vehicle storage tank and cause the pressure to rise suddenly, and the LNG temperature injected into the vehicle storage tank after heavy pre-cooling can reach the lowest. After the end of pre-cooling, you can start to add liquid, if the pressure of the vehicle storage tank is too high in the process of liquid filling, it needs to be exhausted, the filling pressure of the liquid dosing machine is, the higher the pressure in the vehicle storage tank, the slower the filling speed.

I have drawings and can also draw them according to your requirements.
