In a atmospheric and vacuum distillation unit, what is the sequence of one removal and three injections, and why?
Electrodesalination is carried out through water injection and demulsifier addition for desalination and dewatering; ammonia water, a slow-release agent, and water are injected sequentially at the vapor line at the top of the tower.
Reply to 2# Under the rain-soaked sycamores: Ammonia is injected first, with the aim of neutralizing hydrogen chloride and hydrogen sulfide as well as adjusting the pH value of the condensation cooling system. The injection of ammonia in combination with corrosion inhibitors enhances the effectiveness of these inhibitors; since corrosion inhibitor molecules contain polar groups that can adhere to the metal surface to form a protective layer, preventing corrosive agents from coming into contact with the metal surface and thus providing protection. A low pH value can render corrosion inhibitors ineffective, which is why ammonia is injected first to adjust the pH value. Finally, water is added, which helps to lower the dew point and protect the equipment
Reply to 3# Lotus Fairy80: What was said on the third floor is very accurate and thorough.
