ABSTRACT:
Method and apparatus for supplying a gaseous raw material to plural users. A liquid raw material is evaporated by a single evaporation means and supplied to a gaseous raw material takeout portion provided with a plurality of takeout ports. The gas pressure is varied according to amounts of the gaseous raw material taken out of the takeout ports. The pressure variations are regulated by a main pressure-adjusting means mounted downstream of the gaseous raw material takeout portion. Extra gaseous raw material is sent to a gaseous raw material-condensing means, where the material is liquified. Then, the liquified material is fed back to the evaporation means. Thus, a closed circulatory loop circuit is formed. The gas pressure in the gaseous raw material takeout portion is regulated. The gaseous raw material is distributed to plural users at any desired time at their respective flow rates such that supply of the raw material to each individual user is carried out independent of supply to other users.
