Natural gas system for on-site processing

A natural gas processing system for use in connection with a natural gas source and raw source natural gas produced by the source, the natural gas processing system comprising:

• a mobile platform adapted for being transported to the natural gas source;
• a liquid drain juxtaposed with the mobile platform for discharging liquid contaminants from the natural gas processing system;
• a source natural gas inlet connected in fluid communication with the natural gas source;
• a source natural gas valve connected in fluid communication with the natural gas source for controlling the source natural gas entering the natural gas processing system;
• a water separator mounted on the mobile platform, the water separator being connected in fluid communication with the source natural gas valve, the water separator being connected to the liquid drain, the water separator being adapted for removing water liquid from the natural gas, the water separator being adapted for allowing passage of the natural gas therethrough;
• a particulate filter mounted on the mobile platform, the particulate filter being connected in fluid communication with the water separator and the liquid drain, the particulate filter being adapted for removing particulate matter from the natural gas, the particulate filter being adapted for allowing passage of the natural gas therethrough;
• a high natural gas outlet connected in fluid communication with the particulate filter for controlling the natural gas pressure at a predetermined pressure exiting the natural gas processing system;
• a high natural gas outlet valve connected in fluid communication with the high natural gas outlet;
• a low natural gas outlet connected in fluid communication with the particulate filter for controlling the natural gas pressure at a pressure less than the predetermined pressure exiting the natural gas processing system;
• a low natural gas outlet valve connected in fluid communication with the low natural gas outlet;
• a thermoelectric generator mounted on the mobile platform for supplying process electricity, the thermoelectric generator being powered by the natural gas;
• an emergency shutdown valve connected in fluid communication with the natural gas outlet;
• a process control operatively connected to the natural gas processing system, and to the thermoelectric generator, and to the emergency shutdown valve, for controlling the natural gas processing system;
• at least one emergency shutdown control operatively connected to the emergency shutdown valve and to the process control;
• a gas sensor connected in fluid communication with the natural gas outlet, the gas sensor being operatively connected to the emergency shutdown control for direct emergency shutdown;
• and
• a gas analyzer positioned between the water separator and the natural gas outlet and operatively connected to the gas sensor and to the process control for sending data to the process control and to the emergency shutdown control;
• wherein data from the gas analyzer that is sent to the process control does not inform the water separator functionality;
• and
• wherein data from the gas analyzer informs only the actuation of the emergency shutdown control;
• further comprising:
• at least one emergency shutdown control operatively connected to the emergency shutdown valve and to the process control;
• at least one temperature sensor connected in fluid communication with the natural gas outlet, the temperature sensor being operatively connected to the process control;
• and at least one pressure sensor connected in fluid communication with the natural gas outlet, the temperature sensor being operatively connected to the process control;
• further comprising:
• at least one flow sensor connected in fluid communication with the natural gas outlet;
• and at least one flow analyzer operatively connected to the flow sensor and to the process control, the flow analyzer being adapted for conveying data from the flow sensor to the process control;
• further comprising:
• a gas sensor connected in fluid communication with the natural gas outlet, the gas sensor being operatively connected to the emergency shutdown control for direct emergency shutdown;
• and a gas analyzer operatively connected to the gas sensor and to the process control for sending data to the process control;
• and wherein the gas analyzer is a gas chromatograph.
