We have and HDS unit that processes 100% coker naphtha (I don't recommend this operation to ANYONE). It has 3 reactors. The 1st Reactor was ment to be for diolefin saturation and it is placed before the furnace. Sometime ago, it was decided to convert this unit to heavy coker naphtha and a depentanizer was installed before the unit. Since then (I presume) the 1st reactor has become useless. There is no dT, it is too cold to pick silica, ect. I recommended that this reactor be taken out of service. However, at least twice a year the depentanizer is down for about 7 days. What would be the consequence of removing this reactor. Could it be possible to plug the unit heater rapidly?
