Design issues for the nitration reaction, a high-risk process
Thread Content
According to the specification requirements, it is necessary to monitor the flow rate of the nitrating agent. However, nitric acid is added via a sump tank, and it is not appropriate to install flow meters in the pipes that allow for gravity-fed flow. So how can the flow rate of the nitrating agent be monitored?
There’s no contradiction between flowmeter monitoring of flow rate and whether it is flowing by gravity
Flow meters and control valves can be installed on the nitric acid pipeline to regulate the amount of nitric acid added.
