Abstract
The evaluation of chemical-technological processes is necessary from the point of view of raw-material use and energy efficiency. The development of new technological designs for energy utilization within the technological process is necessary. Often energy utilization requires modern equipment. A new profession must be created of industrial power engineering: power engineering for technological processes. This new profession should improve technological designs, not only for better energy utilization but also for construction of equipment for energy utilization. Often an increase in energy efficiency of technological processes requires higher investment cost, therefore economic evaluation is necessary. Several concrete examples (atmospheric crude oil distillation, new technological process NIVOL, new reesterification reactor, distillation column with tensile-metal-packing, hydrogen production by mazout gasification with oxygen and steam, propane-butane mixture production) demonstrate that chemical-technological research and machinery development of new chemical apparatus is a modern way to the utilization of secondary energy resources in the chemical industry.
