Abstract
Where the loss of volatile organics during storage of high gravity oil is minimized by forming a flowable or pumpable gel in the high gravity oil, (and/or condensates and distillates), as they are introduced to a storage vessel, the gel is broken by the addition of a small amount of an amine/formaldehyde reaction product, which may be either a triazine or a mixture of non-triazine reaction products. The previously gelled hydrocarbon may then by more readily moved by draining or pumping into a pipeline.
