Abstract : through analysis of the components of coking on different parts of desullfur system of single tower and the waste water containing sulfur, we find the cause of coking in the stripping desulur system from single tower is the polymerization reaction of carbohydrate and the separattion of varied solid powders, organic compounds, and all corrosive productions of metal out of waste water in high temperature, therefore, the solving method is how to decrease the oil content, how to depolymerize form the carbohydrate and how to antisepticize by vapour of waste water
文摘:對單塔脫硫系統中不同部位的垢物及現場催化含硫污水進行了分析測定,結果表明:塔內污垢成分及含量隨塔體部位的不同而不盡相同,單塔汽提脫硫系統中垢物的形成,主要是由於污水中所含各類粉塵、有機物、金屬腐蝕物等在高溫下因石油碳氫化合物的析出及其單體的聚合反應所致.如何降低污水中的含油成分、減少聚合反應的生成、防止污水蒸氣對塔體材料的腐蝕,是阻垢、除垢和防垢應解決的關鍵問題Standard test method for oxygenates and paraffin, olefin, naphthene, aromatic o - pona hydrocarbon types in low - olefin spark ignition engine fuels by gas chromatography
