Abstract:
1. A system for supplying natural gas to a sales line, the system comprising: an inlet connected to receive natural gas from a well; an outlet connected to discharge the natural gas to a sales line; piping between the inlet and the outlet, the piping including a check valve and a hydrogen sulfide sensor; a separator on the piping for at least partial removal of liquids and solids from the natural gas; a heater connected to receive natural gas from the piping; a moisture sensor on the piping for detection of a predetermined moisture level in the natural gas; a shutdown valve, on the piping, connected to close upon detection by the moisture sensor of a moisture level at or above the predetermined moisture level; an odorant addition unit on the piping; a gas analyzer on the piping for tracking the heating value of natural gas discharged through the outlet, the gas analyzer comprising a cylinder that may be removed from the gas analyzer for use in determining compensation for the natural gas discharged through the outlet; an instrument gas takeoff, connected to receive natural gas from the piping to supply instrument pressure to the shutdown valve; a meter for tracking the volume of natural gas discharged through the outlet; a controller connected for controlling operation of the moisture sensor, the shutdown valve, the odorant addition unit, and the gas analyzer; and in which the system is configured to be portable on wheels or a skid, and the heater, moisture sensor, shutdown valve, odorant addition unit, gas analyzer, and instrument gas takeoff are contained within a housing mounted on the wheels or skid.
