Circular heat exchanger for natural gas liquefication - having refrigerant distribution chamber feeding distributor pipes from top capable of installation on swaying offshore rigs

摘要: Coiled tubular heat exchanger has a system for distributing the coolant over outside of tubes. It centrally located tube which acts as storage and distribution or refrigerant. The refrigerant is distributed from series pipes radiate outwards central pipe it into circular pipes. These have holes along their lower edge correspond to vertical runs coils. Each thus individually irrigated. Used esp. natural gas liquefication on offshore rigs. tendancy towards rocking makes conventional unsatisfactory. described maintains full capacity even if swaying about.
