Strategies for Urea Plant Optimisation

摘要

Urea plant is relatively less complex as compared with ammonia plant.But,due to extensive recycling and relatively simple control loops the optimisation of urea plant is a tricky issue.The amount of water recycling and precise temperature control of the streams play a crucial role in the optimisation of the urea plant.Simple modifications in the control loops without any investment can lead to optimised process parameters leading to saving low-pressure steam to the tune of 4 tph (max.).The modifications are relatively simple and can be done in-house.
