Technology Profile: Acetaldehyde Production from Acetylene

By Intratec Solutions |

This column is based on “Acetaldehyde Production from Acetylene,” a report published by Intratec. It can be found at: www.intratec.us/analysis/acetaldehyde-production-cost. Acetaldehyde (also known as ethanal) is an industrially important, highly reactive aldehyde, mainly used as chemical intermediate in the production of acetic acid, peracetic acid and pyridine bases. Under certain conditions of acetylene price and availability, acetaldehyde can be made economically from that starting material. The process The following paragraphs describe a process for acetaldehyde production from acetylene (Figure 1). Figure 1. The figure shows acetaldehyde production from acetylene[/caption] Hydration. Fresh acetylene is mixed with recycled water and fed to an evaporator. The resulting vapor is mixed with fresh steam, heated and directed to hydration reactors. The reaction is conducted using four fixed-bed reactors, arranged in such a way that while three reactors are operating, one is in a catalyst-regeneration cycle by air injection (not shown in the diagram). The preheated feed mixture is split, and part of it is introduced into the first reactor, where it contacts a bed of solid catalyst. The reaction mixture effluent, comprising…
