Process for transferring heat or modifying a tube in a heat exchanger

摘要

One exemplary embodiment can be a process for transferring heat to a first stream from a second stream in a hydrocarbon process. The process can include passing the first stream through at least one generally vertically-orientated tube in an exchanger. An interior surface of the at least one generally vertically-orientated tube may form one or more curved irregularities where the first stream, prior to entering the at least one generally vertically-orientated tube, may include a mixture of a gas including hydrogen and at least one or more C1-C3 hydrocarbons, and a liquid including one or more C4-C13 hydrocarbons.
