| Summary: | During dispensing natural gas from natural gas dispenser to NGV car storage
tank, mass, pressure and temperature of the natural gas inside the tank are increase.
Based on Ideal Gas Law, as mass is inversely proportional to temperature, the value
of temperature should be as low as possible to get the maximum value of mass of
natural gas dispensed to the tank. Thus, a temperature control system is invented
using instrumentation equipments available in Natural Gas Test Rig and Industrial
Automation Instrumentation Laboratory and simulated using LabView Data
Acquisition software- A cooling mechanism represented by a fan and a heating
mechanism represented by a light bulb are assembled in order to provide a specific
range of temperature of the tank; if the temperature exceeded the highest limit a
cooling system will starts and if the temperature goes below the lowest limit, a
heating system will starts. While thetemperature is within the range, a PID controller
will control the temperature of the tank to a certainvalue that will maximize the mass
dispenses into the tank. |
