Abstract: In the given publication the advanced technological circuit design of 2-ethilgeksanol nitrating process in manufacture
of cetan increase additive to diesel fuel – 2-ethilgeksilnitrate is resulted. With reference to the semi plant the design of the heat
exchanger for tap of heat depositing as a result of nitrating reaction is offered. Calculation of a heat transfer factor is executed and the
basic constructive sizes of the heat exchanger are defined.
Index terms: nitrating of 2-ethilgeksanol, heat transfer, calculation of heat exchanger.
