#CMT# #/CMT# Producing acetylene comprises hydrolyzing calcium carbide with a mixture comprising x wt.% of an aqueous solution of a reducing salt and 100-x wt.% recycled water, where x is a nonzero number. #CMT# : #/CMT# An independent claim is also included for an acetylene production plant suitable for carrying out the above process, comprising a hydrolysis reactor, a pipe for delivering industrial water to the reactor or a decanter, a pipe for delivering acetylene from the reactor to a point of use or storage, a pipe for passing an aqueous calcium hydroxide suspension from the reactor to the decanter, a pipe with a pump for recycling water from the decanter, and a pipe for discharging the decanted suspension from the decanter. #CMT#USE : #/CMT# Producing acetylene. #CMT#ADVANTAGE : #/CMT# The process produces oxygen-free acetylene (see also ). #CMT#CHEMICAL ENGINEERING : #/CMT# Preferred Process: The reducing salt is sodium or potassium bisulfite. The mixture comprises 10-30 wt.% of the solution. |
