Natural Gas Pressure Regulator That Produces Electric Energy

摘要

The invention is a method to regulate gas pressure by controlling the expansion of a gas through an air motor that is attached to an electric generator. There are four components. The first is a sensor that measures the pressure of the gas coming into the air motor. The second is an air motor that changes the pressure of the gas into mechanical energy. The third is a generator that takes the mechanical energy from the air motor and changes it into the electrical energy. The forth is a control unite. The control unit reads the pressure of the gas from the sensor and varies the electric load on the generator. The varying of the electrical load on the generator varies the torque on the air motor which changes the pressure of the gas passing through the air motor.

主权项

1. A system for regulating the pressure of gas in a line to a desired value comprising:
a. a motor that turn gas pressure into mechanical energy with an entrance for the gas and a output for the gas; and, b. a motor generator attach to the motor by a drive train that turn the mechanical energy of the motor into electrical energy; and, c. a sensor that measures the pressure of gas entering the motor; and, d. a control unite; and, e. the sensor sends to the control unite the measurement of pressure of the gas; and, f. the control unit varies the electrical load on the motor generator; and, g. the control unit is program with the value of the desired pressure of the gas that is outputted by the motor; and, h. the varying of the electrical load on the motor generator varies the torque of the motor which varies the pressure of the gas that is outputted by the motor; and, i. the sensor measures the pressure of the gas before it enters the motor and transmits this information to the control unit and the control unit calculates the electrical load necessary to create the torque of the motor that will ensure that the gas will exit the motor at the desired value.
