Corrodes metal equipment, causes catalyst poisoning, and affects product quality
The sulfur, oxygen, and nitrogen-containing non-hydrocarbon compounds in crude oil are transferred to the refined oils. The hazards associated with this include: 1) reduced octane rating of gasoline; 2) decreased stability of the oils during storage, transportation, and use; 3) corrosion of equipment; 4) poisoning of catalysts used in further processing; 5) environmental pollution and harm to human health. Among these, sulfur-containing compounds pose the greatest threat.
1. It affects the quality of petroleum products, reducing their combustion performance and stability. 2. It corrodes equipment. 3. It pollutes the environment. 4. It can poison catalysts
①Severely corrodes equipment and pipelines. ②Toxic gases such as H2S and low-molecular-weight thioalcohols are generated during the processing process, causing air pollution that is harmful to human health. ③Gasoline contains sulfur compounds, which reduce its sensitivity to lead and its stability, thereby deteriorating the properties of the fuel. ④Catalyst poisoning occurs during the catalytic processing of gases and various petroleum fractions. ⑤When burned, it produces SO2, which causes environmental pollution. Large amounts of SO2 emissions, once exceeding the atmosphere’s self-purification capacity and failing to disperse, form acid rain that falls to the ground, leading to soil acidification and harming plant growth.
1) Severely corrodes equipment. 2) Toxic gases such as H2S and low-molecular-weight thiol compounds are generated during the processing process, causing air pollution that is harmful to human health. 3) Sulfur compounds present in gasoline reduce its sensitivity to lead as well as its stability, thereby deteriorating the properties of the fuel. 4) It causes catalyst poisoning during the catalytic processing of gases and various petroleum fractions.
It is mainly manifested in three aspects: affecting the quality of petroleum products； Corrosion equipment ； Pollute the environment
①Severely corrodes equipment and pipelines. ②Toxic gases such as H2S and low-molecular-weight thioalcohols are generated during the processing process.
Answer: 1. Severely corrodes equipment and pipelines. 2. During the processing stage, toxic gases such as H2S and low-molecular-weight thioalcohols are generated, causing air pollution that is harmful to human health. 3. Sulfur compounds present in gasoline reduce its sensitivity to lead as well as its stability, thereby deteriorating the properties of the fuel. 4. Catalyst poisoning can occur easily during the catalytic processing of gases and various petroleum fractions. 5. When burned, sulfur dioxide is produced, leading to environmental pollution; when the amount of sulfur dioxide exceeds the atmosphere’s capacity to purify itself, it cannot be diluted or dispersed, resulting in acid rain that falls to the ground and causes soil acidification, thus affecting plant growth
