The cumene process for phenol-acetone production - PDF ...
Thus, the problem of environmentally hazardous gas emissions during the cumene process is successfully resolved. Cumene Hydroperoxide Concentration Step Loss in selectivity at this step is 0.1 to 1.2 abs. % and is predetermined by the chemical idea of the cumene oxidation process, rather than the engineering design of the concentration step.

Application of Cumene Technology Mathematical Model
Cumene output is 35 ± 1%, more than 15% of the amount of produced cumene is waste. The production instability manifests itself in the increased volume of heavy impurities (polyalkylbenzenes and tar) in the reaction mixture of alkylation. Current problems in the cumene technology are product quality and alkylation temperature reduction below the

Chemical plant - Wikipedia
A chemical plant is an industrial process plant that manufactures (or otherwise processes) chemicals, usually on a large scale. The general objective of a chemical plant is to create new material wealth via the chemical or biological transformation and or separation of materials. Chemical plants use specialized equipment, units, and technology in the manufacturing process.
