[Q&A Question 008] Why is it necessary to control the oxygen content in water during hydrogenation and water injection? 2016.04.28 The answer key will be available after responding; scoring is based on addressing the key points. This is because the oxygen dissolved in water oxidizes hydrogen sulfide or other sulfides present in the reaction effluent, forming elemental sulfur, which causes problems such as blockages, corrosion, and difficulties in separating it from the product.
The purpose of injecting water is to prevent ammonia salts from clogging the pipes, while controlling the oxygen content is to avoid introducing oxygen into the reaction system
When oxygen from water enters the system, it reacts with olefins to form gums, which affect normal production.
Why is it necessary to control the oxygen content in water during hydrogenation and water injection? Among the requirements for the quality of water used for injection, the oxygen content in the water is an indicator that needs to be strictly controlled. This is because the oxygen dissolved in water oxidizes hydrogen sulfide or other sulfides present in the reaction effluent, forming elemental sulfur, which causes problems such as blockages, corrosion, and difficulties in separating it from the product.
Prevent the formation of explosive substances. Prevent excessive heat and inadequate heat dissipation

Oh. . . . So there is also the issue of sulfur buildup. . . Learned* it

This is because the oxygen in water will oxidize hydrogen sulfide or other sulfides present in the reaction effluent, forming elemental sulfur, which can cause problems such as blockages, corrosion, or difficulties in separating it from the product.
Dissolved oxygen in water oxidizes hydrogen sulfide or other sulfides present in the reaction effluents, forming elemental sulfur, which can cause problems such as blockages, corrosion, and difficulty in separating it from the product.
