New operation strategies in heavy crude pipeline will increase profit margin

An engineering study for a heavy-oil pipeline in Venezuela has confirmed the design of optimizing the temperature of crude entering the pipeline to levels that will increase throughput and reduce the size of the heaters at the pump station.The study found that throughput for heavy crude pipelines is not necessarily a simple function of crude inlet temperature as commonly believed in normal crude pipelines.Varying the pipeline inlet temperature for each type of crude enables the optimization of pipeline capacity and minimize heating costs.Of four heating schemes evaluated, one yielded the lowest heater capital and fuel costs. This operational procedure required delicate control of crude te...
