WebBy mile 30, the temperature of the pipeline system is a few degrees higher than the deep ocean temperature (~39 °F), so that approximately 23 wt% methanol is required in the free water phase to shift the hydrate formation region to the left of flowline conditions to prevent hydrate formation and blockage. WebJun 2, 2014 · During the last decade, however, direct electrical heating (DEH) has emerged as an attractive alternative. DEH controls the flowline temperature to maintain it above the critical threshold for hydrate formation. By heating the flowline electrically, the need for chemical injections is reduced considerably.
