A method and a control unit for evaluating lifting force of a gas phase of a substantially vertical upward two-phase flow of a first fluid in a heat exchanger. The first fluid comprises the gas phase and a liquid phase. The method comprises determining that the lifting force of the gas phase is insufficient for lifting the liquid phase based on hot end approach of the heat exchanger and/or on pressure drop of the first fluid over the heat exchanger. The control unit is configured to determine that the lifting force of the gas phase is insufficient for lifting the liquid phase based on hot end approach of the heat exchanger and/or on pressure drop of the first fluid over the heat exchanger. A heat exchanger assembly comprising a heat exchanger and the control unit.

A furnace and a process for temperature control of a material stream, wherein the furnace has a first combustion chamber, at least one reactor tube for receiving the material stream to be heated, and at least one second combustion chamber. The at least one reactor tube extends through the first combustion chamber and through the at least one second combustion chamber. The furnace is designed to establish a first temperature in the first combustion chamber and a second temperature in the at least one second combustion chamber, wherein the first temperature and the second temperature are separately adjustable.
