    • In method of providing uniformity of vapour and liquid phases in two or more streams derived from a mixed vapour and liquid stream (10), the mixed vapour and liquid stream (10) passes from a first heat exchanger (101) into a distribution vessel (12) via one or more inlets (14). The distribution vessel (12) has two or more outlets (16) connected to a second heat exchanger (102). The liquid part of the mixed stream (10) is allowed to collect in a first area (20) in the distribution vessel (12), and the vapour part of the mixed stream (10) is allowed to collect in a second area (30) of the distribution vessel (12), preferably above the first area (20). The liquid in the first area (20) passes into the outlets (16) via one or more liquid apertures (18) in each outlet (16) that communicate with the first area (20), and the vapour in the second area (30) passes into the outlets (16) via one or more vapour apertures (28) in each outlet (16) communicating with the second area (30).
