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.

对单塔脱硫系统中不同部位的垢物及现场催化含硫污水进行了分析测定，结果表明：塔内污垢成分及含量随塔体部位的不同而不尽相同，单塔汽提脱硫系统中垢物的形成，主要是由于污水中所含各类粉尘、有机物、金属腐蚀物等在高温下因石油碳氢化合物的析出及其单体的聚合反应所致。如何降低污水中的含油成分、减少聚合反应的生成、防止污水蒸气对塔体材料的腐蚀，是阻垢、除垢和防垢应解决的关键问题。

To restore the ability of chromium can be dissolved in sulfuric acid, hydrochloric acid and High-FE acid and release hydrogen, but also of pure chromium with aqua regia does not work, when there is the presence of halogen ions in the acid can not be long-term stability, high temperature with alkali, hydrogen sulfide, sulfur steam, phosphorus, ammonia, such as carbon monoxide and water vapor reaction of the corresponding compounds, in the high temperature reaction of silicon into the silicide also chromium, chromium alloys with many metals generate a wide range of industrial applications, such as chromium-manganese stainless steel is used extensively for chemical plants.

铬的还原能力强，能溶于硫酸、盐酸和高FE氯酸而放出氢气，但纯铬连王水也不起作用，当有卤素离子存在时，在酸中不能长期稳定，高温时能与强碱、硫化氢、硫蒸汽、磷、氨、一氧化碳和水蒸汽等反应生成对应的化合物，在高温下还能与硅反应成硅化铬，铬能与许多金属生成合金广泛在工业上应用，如铬锰不锈钢大量用于化工设备。

Comparing it with the standard electrode potential of nitric acid,the reason of dissolution of HgS in aqua regia was quantitatively revealed,and this is that the high concentration of chloride ions reduces the reduction potential of sulfur in HgS,thus raising the reducing power of HgS rather than that the oxidizing power.

根据热力学平衡原理和设计的可逆电池反应，由 E~0Hg~(2++S/HgS数据，计算了 E~0HgCl_4~(2++S/HgS+4Cl~-数值，将其与 HNO_3的标准电极电位比较，定量地揭示了 HgS 溶于王水的原因在于该溶液中高浓度 Cl~-离子降低了 HgS 中硫的还原电位，从而提高了 HgS 的还原性所致，并非王水的氧化性比 HNO_3的更强。
