Historically, there has been a perception in the industry that it is not safe to include a steam generator in the high-pressure loop of a hydrocracker. However, this article intends to demonstrate that it is possible to achieve safe design of a steam generator in that service.
FIG. 1 shows a typical scheme for a high-pressure loop for a hydrocracker, where the feed is heated to high temperature (> 450°C) by the equipment upstream of the reactor, and the equipment located downstream of the reactor recovers as much heat from the feed as possible. Extra heat is generated in the reactor as the cracking reactions are exothermic; this heat can also be recovered.
