referring to fig3 pressure vessel 32 includes a dip tube 33 that extends to the bottom of vessel 32 by opening a valve connected to dip tube 33 the pressure in pressure vessel 32 will force any liquid out of dip tube 33 accordingly it is preferred to have pressure vessel 32 at a slight angle such that the liquids accumulate at dip tube 33 referring to fig2 once pressure vessel 32 is filled it is transported to an unloading station 35 and offloaded unloading station 35 may be located at a processing plant an access point to a natural gas pipeline or at the end user directly a pressure reducing station 36 may be used to obtain a low pressure output as is known in the art in one example the pipeline at unloading station 35 may have a pressure of 250 300 psi resulting in an u201c empty u201d pressure of 350 400 psi for pressure vessel 32 the pressure in pressure vessel 32 after unloading will vary depending on the pressure at unloading station 35 some compressors 26 may be limited in their minimum output to for example 600 psi accordingly the compressed gas will experience a pressure drop as it is loaded into pressure vessel 32 which may result in condensates forming this may be avoided by only emptying pressure vessel 32 to match the minimum pressure that can be achieved by compressor 26 or using a compressor with a lower minimum output however another solution.
