RECONSTRUCTION OF THE CONNECTION OF PIPES TO THE GRID IN THE AIR-COOLING UNIT

The article analyzes the types of pipe connections with a pipe grid in air-cooling devices. Based on this analysis, it is proposed to change the design of pipe fastening instead of rolling to tightening nuts in ABO-103/1-2 of the sulfuric acid alkylation unit

THE IMPROVING EFFICIENCY OF AIR COOLING APPARATUS OF THE INSTALLATION OF A SULFURIC ACID ALKYLATION

The study of the efficiency of the heat transfer process in the air cooling apparatus, which is part of the installation of a sulfuric acid alkylation, at different finning coefficients of heat exchange pipes

ENHANCING ENERGY USAGE IN THE TECHNOLOGY OF SULFURIC ACID REGENERATION IN THE ALKYLATION PROCESS

The main approaches to energy efficiency analysis of sulfuric acid regeneration technology in the process of sulfuric acid alkylation are considered

Optimal Control of the Separation Process with Flow Restrictions

Here we formulate the problem of optimal process control with distributed parameters, taking into account the constraints on the control and associated flows. The necessary optimality conditions are obtained. The analysis of the stationarity conditions is carried out and the method for constructing the domain of admissible controls is proposed. The developed optimization method is applied in the automation of industrial distillation plants for the sulfuric acid alkylation of isobutane with butylenes, ortho-xylene production, etc.
