The new Acetylene Plant
The quenching process, for example, which causes an abrupt cancellation of the currently running reaction through cooling, was changed from an industrial oil mixture to water. The new process efficiently delivers the desired end products, the amount of organic by-products was minimized and the acetylene plant thus contributes to sustainability.

Production Process of Acetylene
Acetylene is pumped into the cylinders at a pressure of about 300 psi (2,070 kPa) and it gets dissolved into acetone. When it is dissolved, it loses its capacity to explode and is now safe for transportation. On opening the cylinder valve, the pressure drop makes acetylene to vaporize into gas again and flow through the connecting hose to the ...

Question: Acetylene gas (C_2H_2) is burned completely with dry air in a steady flow combustion process. The air-fuel ratio on a mass basis is 15.9. The fuel and air enter the combustion chamber at 25 degree C, and the products leave at 1500K. Determine the following: the balanced reaction equation the heat transfer (kJ/kmol) for the process.
BASF and Acetylene – 70 Years of Reppe Chemistry – …
Abstract. Acetylene is still an attractive intermediate synthesis component because carbon in methane from natural gas comes at a lower price than carbon in naphtha from crude oil or coal. Acetylene can be understood as a product of C-C coupling and functionalization. Beginning in the 1950s, BASF developed the partial oxidation (Pox) process ...

How The Acetylene Plant Process Works In 8 Simple Steps
Step 2: COOLING Chamber. The acetylene generated is passed from the generator chamber through wet type flashback arresters into a low pressure condenser. Here, the temperature of the gas is lowered by water cooling. This also removes part of the moisture in the acetylene in the form of condensed water.
