The Research Of NorthⅡ-2 Cryogenic Unit Operation Evaluation And Potential

Natural gas as a valuable resource in the increasingly tense energy plays a more and more important role today.Not only can recycle gas light hydrocarbon will take advantage of light hydrocarbon,can also improve the quality of the gas,reduce the dew point of natural gas,reduce the loss of the oil and gas to improve the overall economic and social benefits of natural gas.This article through in-depth investigation,analyze the present situation of plant operation unit of the main equipment and technical parameters of the calibration,accounting machine pump,heat exchanger,tower,separator,such as main equipment operation efficiency,material balance and energy balance analysis device,comparing the difference between actual operation and the original design conditions,comprehensive and accurate evaluation and monomer equipment running effect.And affect product yield,analyzing and evaluating system and the related factors of monomer equipment energy consumption and unreasonable link in diagnosis device operation,optimized improvement measures are put forward,the comprehensive mining equipment production and energy saving potential.First of all,through the evaluation in each unit and unit equipment,determine the indications device of production capacity,light hydrocarbon yield and energy consumption level,the overall index indicators,accounting the machine pump,heat exchanger,tower,separator,such as main equipment operation efficiency,analyzed the material balance and energy balance,comparing the difference between actual operation and the original design conditions,comprehensive and accurate evaluation of devices and equipment running effect;Based on the refrigeration device after the minus temperature didn’t meet the design value,parameter matching problems such as unreasonable,research on the optimal operation scheme,determine the optimal operation point and the key process parameters.Device parameters adjusted according to the presented optimization scheme,light hydrocarbon yield from the current 0.74 t up to 104 m3/0.81 t/m3,104 annual production of 3234 tons of light hydrocarbon,saving 279 x 104 KWH.
