Ethoxylation and/or propoxylation are performed in industry to produce surfactants and polyglycols. The reaction is normally promoted by an alkaline catalyst (such as NaOH or KOH) and is performed in gas-liquid stirred reactors, Venturi loop reactors, and spray tower loop reactors. In the first two types of reactors, the gas phase is dispersed into the liquid phase; on the contrary, in the latter case, the liquid phase is dispersed into the gaseous one. In this paper, the key factors in ethoxylation/propoxylation technology will be examined: (i) the types of reactors employed and their performances; (ii) the role of kinetics and mass transfer in the process; and (iii) safety.

An integrated procedure for the identification and execution of the design tasks for processes containing crystallization and solids processing steps is presented as an illustration of workflow management for process synthesis and development. It integrates a number of stand-alone systematic design procedures into a coherent whole and includes crystallization system synthesis, crystallizer downstream processing, and bulk solids processing. Solid-liquid equilibrium phase diagrams are developed first as a basis for crystallization-based separation synthesis. Flowsheet alternatives for the separation process, as well as for the crystallizer downstream processing, are constructed based on the process objectives. Next, the design and operating policy of the crystallizer as well as the downstream units are optimized to produce the desirable crystal size distribution. This is followed by synthesis of the bulk solids processing steps and evaluation of operational problems to ensure plant operability. The design is finalized using additional information from pilot-plant tests and equipment vendors.
