    Abstract: In a process for the production of acetylene and/or lower olefins from hydrocarbons the enthalpy of cracked gas is recovered in two stages by an oil wash. In the first stage of the oil wash using temperatures within the boiling range of the wash oil and approximately atmospheric pressures, a cycle of highboiling oil components is maintained and condensed lower boiling oil components which are recycled from the second wash stage are directly vaporized by the cracked gases. The saturated mixture of oil vapor and cracked gases formed in the first stage is fed to the second wash stage and condensed therein by indirect cooling.

In the first stage of the oil wash using temperatures within the boiling range of the wash oil and approximately atmospheric pressures, a cycle of high-boiling oil components is maintained and condensed lower boiling oil components which are recycled from the second wash stage are directly vaporized by the cracked gases. The saturated mixture of oil vapor and cracked gases formed in the first stage is fed to the second wash stage and condensed therein by indirect cooling.
