Abstract:
A cost effective method for revamping a low pressure distillate hydrotreating process unit to a high pressure distillate hydrotreating process unit. A high pressure hot-feed pump is added, the furnace is retubed for higher pressures, the low pressure reactor is replaced with a high pressure reactor, a high pressure let-down valve is added at the reactor outlet, and the low pressure recycle compressor is replaced with a high pressure recycle compressor.
