Abstract

Aiming at the practical problem of increased C₃+ content in the feedstock for industrial isobutane production at the Butane Plant of Zhongyuan Oilfield Natural Gas Treatment Plant, this paper investigates the effects of C₃+ content fluctuation on key process parameters, and further optimizes the regulation methods for production parameters. When light components in the process materials for industrial isobutane production rise significantly, key control parameters including the overhead temperature of the isobutane column, the overhead temperature of the purification column and the C₃+ content in No.1 reflux drum are kept within the standard ranges. This prevents the accumulation of C₃+ components and unplanned shutdown reflux of the unit, improves the adaptability of the industrial isobutane production process to variations in feedstock composition, and ensures continuous and stable production of qualified industrial isobutane products.
