| Abstract: | A high precision ratio control strategy and its implementation framework are proposed on the analysis of the crude oil pipeline blending process. Based on the multiple cascade ratio control,the high precision ratio automatic blending of crude oil components is achieved through the oil flow deviation scrolling correction,crude oil pipeline warning against excessive pressure and crude flow synchronization control within the three-layer framework as device layer, control layer and monitoring layer. The actual effect shows that the system can realize safe,accurate and automatic blending in required proportion of crude oil components, avoid fluctuations in nature, produce the crude oil meeting the requirements, and improve the production efficiency of the processing equipment. |
