Example Embodiment

[0016] Example 1

[0017] Such as figure 1 Shown, a natural gas filling method,

[0018] (1) Natural gas is sent to the gas filling station via pipeline or skid-mounted gas cylinder group;

[0019] (2) Natural gas enters the compressor through the pipeline and is pressurized to a filling pressure of 20Mpa;

[0020] (3) Dehydrate and deoil natural gas;

[0021] (4) Cooling the natural gas, the temperature of the natural gas after cooling is not higher than the ambient temperature by 15℃, namely T natural gas ≤T surroundings +15℃, where T natural gas Is the natural gas temperature after cooling, T surroundings Is the ambient temperature;

[0022] (5) The natural gas is transported to the gas storage well or gas dispenser and measured;

[0023] (6) The natural gas is cooled by the cooling device and then filled into the vehicle-mounted gas cylinder. The cooling treatment process makes the natural gas temperature range from 40°C below the ambient temperature to 0°C below the ambient tempe...

Abstract

The invention provides a natural gas filling method. The natural gas filling method comprises the step of carrying out cooling treatment on natural gas through a cooling device before filling a vehicle-mounted gas cylinder with natural gas, the cooling treatment range of the natural gas temperature is 0 DEG C to 40 DEG C lower than the environment temperature. According to the natural gas filling method, through reduction of the natural gas temperature before filling, the effective volume utilization ratio of the vehicle-mounted gas cylinder is increased, the vehicle travel mileage is increased, the filling times are reduced, the deadhead kilometres and time for a gas station roundtrip are reduced, the excessive power consumption during pressure compensation pressurization of a compressor is reduced, and the beneficial effects of saving energy and increasing economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of natural gas filling methods, and in particular relates to a natural gas filling method. Background technique [0002] CNG, or Compressed Natural Gas (CNG for short), is natural gas that is pressurized and stored in a gaseous state in a container. In addition to the natural gas in oil fields and natural gas fields, compressed natural gas can also be used to artificially produce biogas (mainly composed of methane). CNG can be used as vehicle fuel. It is an ideal alternative energy source for vehicles, and its application technology has become increasingly mature after decades of development. It has the characteristics of low cost, high benefit, no pollution, safe and convenient use, etc., and is increasingly showing strong development potential. [0003] CNG refueling station refers to a place that provides fuel to natural gas vehicles and large CNG sub-station vehicles in the form of compressed natural ...
