METHOD FOR SUPPLYING ACETYLENE

摘要

A method for supplying acetylene is provided for the purpose of supplying high-purity acetylene efficiently to a user. The method is characterized by supplying high-purity acetylene at a pressure up to atmospheric pressure to an acetylene user, said high-purity acetylene being produced by a process which comprises: an acetylene gas production step of reacting calcium carbide with water to produce a gas comprising acetylene as the main component; a water-removal step of removing water from the gas produced in the acetylene gas production step by bringing the gas into contact with a first dry adsorbent and thereby causing the water contained in the gas to be adsorbed on the first dry adsorbent; and a hydride-removal step of bringing the gas which has undergone the water-removal step into contact with a second dry adsorbent to remove hydride-type impurities contained in the gas.
