Abstract
A heat integrated hydrotreating process has been invented. The feedstock is a cracked hydrocarbon stock which is mixed with hydrogen to suppress coking before heating in a multiple tube furnace to reactor inlet temperature. A minor portion of the feedstock is mixed with hydrogen and heated to reactor inlet temperature by quenching the hot reactor effluent. The minor portion is fed directly to the hydrogenation reactor, bypassing the furnace. By the process, high level heat is recovered.
