​​​​Negligible heat loss & maintenance costs​ ie cleaning and operational costs

Heat transfer in exchangers occurs to maximum efficiency ​

Units (heat exchangers, heaters and coolers) have no effect on pressure of the fluid​ and are designed to induce maximum turbulence to reach the desired temperature

Any reconfiguration of plant is possible​

We can reuse old units​

Streams temperatures entering/leaving plant must not change​

The cost of steam and cooling water won't change over the next 5 years
