Description
本揭露是有關於一種預測儲槽槽位的方法，且特別是有關於一種預測焦爐氣儲槽槽位的方法。The present disclosure relates to a method for predicting storage tank slots, and in particular, to a method for predicting coke oven gas storage tank slots.
在石化工業中，煉焦製程所產生的焦爐氣可儲放於焦爐氣儲槽中，並在需要時用於供給至各生產工廠以作為發電能源。In the petrochemical industry, the coke oven gas produced by the coking process can be stored in coke oven gas storage tanks and used to supply to various production plants as power generation energy when needed.
在普遍情況下，單一焦爐氣儲槽經常連接多個生產工廠，以藉由管網等連接設備供應能源。若是發生焦爐氣缺乏的情況，焦爐氣儲槽槽位以及管網壓力容易過低而造成運轉上的風險。具體而言，當管網壓力低於400mmH 2O時，各個工廠的廠內設備便有可能因為電力不足而有跳機的現象。此時常見的作法是將天然氣人為手動地注入，拉高焦爐氣儲槽槽位，以避免廠內設備跳機。但天然氣的注入量如何影響焦爐氣儲槽槽位實際上難以預測，人們往往只能依據經驗來調整天然氣的注入量。若是經驗不足的操作者，便有可能無法及時地調整天然氣注入量，而導致廠內設備跳機的憾事。故，如何準確預測焦爐氣儲槽槽位的變化，在焦爐製程中便成了至關重要的議題。 Under normal circumstances, a single coke oven gas storage tank is often connected to multiple production plants to supply energy through connecting equipment such as pipeline networks. If there is a shortage of coke oven gas, the pressure in the coke oven gas storage tank and pipe network will easily be too low, causing operational risks. Specifically, when the pipe network pressure is lower than 400mmH 2 O, the equipment in each factory may trip due to insufficient power. At this time, a common practice is to manually inject natural gas and raise the coke oven gas storage tank to avoid equipment tripping in the plant. However, it is actually difficult to predict how the amount of natural gas injected will affect the location of the coke oven gas storage tank. People often can only adjust the amount of natural gas injected based on experience. If the operator is inexperienced, he may not be able to adjust the amount of natural gas injection in time, which may cause the equipment in the plant to shut down. Therefore, how to accurately predict the changes in the coke oven gas storage tank position has become a crucial issue in the coke oven manufacturing process.
因此，亟需一種可精準預測焦爐氣儲槽槽位的方法，能藉由焦爐氣儲槽的過往參數預測一定時間內的焦爐氣儲槽槽位變化，以供線上工作人員在瀏覽預測結果後即時注入天然氣，進而避免焦爐氣儲槽的槽位過低。Therefore, there is an urgent need for a method that can accurately predict the coke oven gas storage tank slots. It can predict the coke oven gas storage tank slot changes within a certain period of time based on the past parameters of the coke oven gas storage tanks for online staff to browse. Natural gas is injected immediately after the prediction result to prevent the coke oven gas storage tank from being too low.

由上述本揭露實施方式可知，本揭露主要是透過迴歸分析分別取得焦爐氣壓力對焦爐氣儲槽槽位變化關係式以及天然氣輸入量對焦爐氣儲槽槽位變化關係式，再結合焦爐氣壓力對焦爐氣儲槽槽位變化關係式以及天然氣輸入量對焦爐氣儲槽槽位變化關係式，來預測天然氣注入後焦爐氣儲槽槽位的長期變化。本揭露之預測焦爐氣儲槽槽位的方法在預測上具有高度的準確性，且能即時呈現預測結果給線上工作人員，故可有效避免焦爐氣儲槽槽位過低而發生各工廠設備跳機的情況。另外，天然氣輸入量對焦爐氣儲槽槽位分析還包含資料清洗作業，以移除無效資料以及低關聯性資料，進而提升分析的準確性。It can be seen from the above embodiments of the present disclosure that the present disclosure mainly obtains the relationship between the coke oven gas pressure and the change of the coke oven gas storage tank slot and the relationship between the natural gas input amount and the change of the coke oven gas storage tank slot through regression analysis, and then combines the relationship between the coke oven gas pressure and the coke oven gas storage tank slot. The relationship between gas pressure and the change of coke oven gas storage tank slots and the relationship between natural gas input volume and coke oven gas storage tank slot changes are used to predict the long-term changes in coke oven gas storage tank slots after natural gas injection. The disclosed method for predicting coke oven gas storage tank slots has a high degree of accuracy in prediction, and can instantly present the prediction results to online staff. Therefore, it can effectively avoid the occurrence of excessive coke oven gas storage tank slot levels in various factories. The device tripped. In addition, the analysis of natural gas input volume on coke oven gas storage tank slots also includes data cleaning operations to remove invalid data and low-relevance data, thereby improving the accuracy of the analysis.
雖然本揭露已以實施例揭露如上，然其並非用以限定本揭露，任何所屬技術領域中具有通常知識者，在不脫離本揭露的精神和範圍內，當可作些許的更動與潤飾，故本揭露的保護範圍當視後附的申請專利範圍所界定者為準。Although the disclosure has been disclosed above through embodiments, they are not intended to limit the disclosure. Anyone with ordinary knowledge in the technical field may make slight changes and modifications without departing from the spirit and scope of the disclosure. Therefore, The scope of protection of this disclosure shall be determined by the scope of the appended patent application.
