Energy-Saving Design of Urea Method for Hydrazine Hydrate Process

Processes, Journal Year: 2025, Volume and Issue: 13(5), P. 1585 - 1585

Published: May 20, 2025

The conventional urea-based process for hydrazine hydrate production faces challenges including low product yield and high energy consumption. To overcome these limitations, we propose an innovative integrated approach combining jet reactor technology with membrane separation, further enhanced through heat network optimization. Through simulation sensitivity analysis, the following optimal distillation parameters were identified: nine theoretical stages, feed entry at fifth stage, a reflux ratio of 0.6, distillate flow rate 354 kg/h. Systematic optimization exchanger (HEN) using pinch achieved substantial savings, reducing hot utility consumption by 66.8% (to 1317 MJ/h) cold usage 62.7% 1503 MJ/h). redesigned HEN prioritized temperature-cascaded recovery, enabling 67% recuperation from exothermic reaction streams. Operational costs decreased 12%, underscoring economic viability coupling intensification thermal integration. This work establishes sustainable framework synthesis, balancing industrial feasibility reduced environmental impact in chemical manufacturing.
