The basic principle of natural gas residual pressure power generation technology is to replace the traditional pressure regulating valve with an expander and use the mechanical energy generated when the high-pressure natural gas is expanded and depressurized to directly drive the generator to generate electricity.
Natural gas differential pressure power generation is a technology that utilizes pressure difference to generate power and drive a generator to generate electricity, and the output power of the generator can be adjusted according to the size of the pressure difference, the flow rate of the incoming gas, and the temperature .
The advantage of this power generation technology is that it not only recycles the pressure energy of natural gas to generate power, but also utilizes the cold energy produced by the depressurization process of natural gas, which improves the utilization rate of energy, produces by-product CNG, and improves the economic benefits of the product.
Therefore, under the current operating conditions, it is recommended to use the double expansion differential pressure power generation technology to recycle the pressure energy of natural gas.
