A process for treating natural gas or other methane-rich gas to remove excess nitrogen and carbon dioxide simultaneously. The invention relies on membrane separation using nitrogen/methane and carbon dioxide/methane selective membranes. The gas can typically be brought to pipeline specification for both components, without requiring the use of amine scrubbing or other acid gas removal technique. Where water vapor or hydrogen sulfide is present in the raw gas, these contaminants may also be removed to meet pipeline specification in a single operation.

An inertial training apparatus as claimed in claim 6, further comprising an upper tether guide coupled to the vertical member and a lower tether guide coupled to the vertical member below the upper tether guide, wherein the tether passes from the intermediate tether guide, through one of the upper and lower tether guides, and then to the body part. 9. An inertial training apparatus as claimed in claim 8, wherein at least one of the upper tether guide and the lower tether guide is adjustably coupled to the vertical member for variable vertical positioning along the vertical member. 10. An inertial training apparatus as claimed in claim 1, further comprising at least one stop at least partially defining an extent of motion of the carriage. 11. An inertial training apparatus comprising: a frame; a swing arm having an axis and a length, the swing arm substantially horizontally rotatably coupled to the frame about the axis; a first mass stacking position on the swing arm at a first distance from the axis; a primary tether guide coupled to the frame; and a tether moveable through the primary tether guide, the tether having two ends, one end coupled to the swing arm and another end engagable with a body part. 12. An inertial training apparatus as claimed in claim 11, further comprising a mass removably received at the first mass stacking position. 13. An inertial training apparatus as claimed in claim 11, wherein the first mass stacking position is adjustable to vary the first distance from the axis. 14. An inertial training apparatus as claimed in claim 11, further comprising a second mass stacking position on the swing arm at a second distance from the axis. 15. An inertial training apparatus as claimed in claim 11, further comprising: a vertical member coupled to the frame; and at least one intermediate tether guide coupled to the vertical member and through which the tether passes, wherein the intermediate tether guide is located between the primary tether guide and the body part along the tether. 16. An inertial training apparatus as claimed in claim 15, wherein the intermediate tether guide is adjustably coupled to the vertical member for variable vertical positioning along the vertical member. 17. An inertial training apparatus as claimed in claim 15, further comprising an upper tether guide coupled to the vertical member and a lower tether guide coupled to the vertical member below the upper tether guide, wherein the tether passes from the intermediate tether guide, through one of the upper and lower tether guides, and then to the body part. 18. An inertial training apparatus as claimed in claim 17, wherein the upper tether guide and the lower tether guide are adjustably coupled to the vertical member for variable vertical positioning along the vertical member. 19. An inertial training apparatus as claimed in claim 11, wherein the swing arm is rotatable through a range of positions, the apparatus further comprising at least one stop at least partially limiting the range of positions of the swing arm. 20. A method of using an inertial training apparatus having a swing arm mounted for rotation about an axis, the swing arm rotatable between and including a starting point, an intermediate point, and a finishing point and having a first stacking position located a first distance from the axis, the apparatus having a tether with one end attached to the swing arm and another end engagable by a body part, the method comprising the steps of: engaging the tether with the body part; rotationally accelerating the swing arm about the axis from the starting point by pulling upon the tether with the body part; passing the swing arm though the intermediate point to transition acceleration of the swing arm into deceleration of the swing arm; and rotationally decelerating the swing arm between the intermediate point and the finishing point by resisting the motion of the tether with the body part. 21. The method as claimed in claim 20, wherein the apparatus has a first mass removably received at the first stacking position, the first mass having an magnitude, the method further comprising adjusting the magnitude of the first mass. 22.

The method as claimed in claim 20, wherein the apparatus includes: a primary tether guide located adjacent to the swing arm; a vertical member; and an intermediate tether guide adjustably coupled to the vertical member and located between the primary tether guide and the body part, the method further comprising adjusting a vertical height of the intermediate tether guide coupled to the vertical member. 25. The method as claimed in claim 24, wherein the apparatus has an additional tether guide adjustably coupled to the vertical member and located along the tether between the intermediate tether guide and the body part, wherein the additional tether guide is one of either an upper tether guide substantially above the intermediate tether guide and a lower tether guide substantially below the intermediate tether guide, the method further comprising vertically adjusting the additional tether guide coupled to the vertical member. 26. The method as claimed in claim 25, further comprising removing the tether from the additional tether guide and positioning the tether into another tether guide located on an opposite side of the intermediate tether guide along the vertical member. 27. The method as claimed in claim 20, wherein the apparatus has at least one stop, the method comprising positioning the stop adjacent the swing arm at the finishing point.
