Automatic control of hydrochloric acid, automatic ignition!
Thread Content
I would like to ask whether there are any regulations requiring that three-in-one reactors used for producing high-purity hydrochloric acid be equipped with automatic control systems, with no human operation allowed at the site. Also, is automatic ignition mandatory? How is the usage in various factories? Thank you!
Automatic ignition is not mandatory, but all synthesis furnaces now use automatic ignition; the technology has become highly mature nowadays, and the success rate of a single ignition attempt is very high!
Currently, there are no mandatory regulations regarding whether automatic ignition should be used in two-in-one HCl synthesis furnaces or three-in-one hydrochloric acid synthesis furnaces. Based on the current situation, many two-in-one HCl synthesis furnaces are equipped with automatic ignition systems, but in some of these furnaces, the automatic ignition system may not function properly and serves merely as an ornamental feature ； Few three-in-one hydrochloric acid synthesis furnaces are equipped with automatic ignition devices.
Automatic control is a mandatory requirement, but automatic ignition is not yet a mandatory requirement!
The third floor is supported; in other words, there’s no need to install an automatic ignition system for those with low production volumes. For those with high production volumes, the hydrogen ignition pipelines are larger, requiring more manual effort for ignition, which poses certain risks; automatic ignition can be considered as an alternative.
Automatic ignition for the hydrogen chloride synthesis furnace is not mandatory, but remote control of the synthesis furnace is required.
Automatic ignition is the trend of development. Our company uses two-in-one synthesis furnaces, which have a very high success rate for automatic ignition; since switching to automatic ignition in 2009, we have not used manual ignition anymore. Firstly, automatic ignition enables remote control, which is very safe ； Secondly, automatic ignition does not require much experience; one just needs to start the automatic ignition procedure ； After successful automatic ignition, the flow rates of chlorine and hydrogen are increased proportionally, allowing for relatively accurate control ； Once the automatic ignition procedure is started, nitrogen is injected for protection immediately if ignition fails.
Automatic control is required, as stipulated by national standards. There are distance requirements for on-site personnel from the fusion furnace.
