摘　　要：某炼油厂循环水系统每天的计算水损失量与实际水损失量存在一定的偏差。针对该问题,对该套循环水系统水量损失的计算情况进行了校正。通过试验装置的水量损失数据与计算数据对比并利用最小二乘法进行拟合,拟合后的曲线最优区间变化斜率k控制在1.06~1.09且循环水最优区间变化截距b控制在14~19时,实际损失量与计算数值的偏差率可控制在5%以内;当k取值为1.07且b取值为15时,最大偏差率仅为4.77%,验证了该算法的可行性。There is a certain deviation between the calculated daily water loss and the actual water loss in the circulating water system of a certain refinery.Regarding this issue,the calculation of water loss in the circulating water system has been corrected.By comparing the water loss data of the experimental device with the calculated data and using the least squares method for fitting,the deviation rate between the actual loss amount and the calculated value can be controlled within 5%when the optimal interval change slope k of the fitted curve L is controlled between 1.06-1.09 and the optimal interval change intercept b of the circulating water is controlled between 14 and 19.When k is set to 1.07 and b is set to 15,the maximum deviation rate is only 4.77%,which verifies the feasibility of the algorithm.
