Do distillation towers and distillation kettles in general chemical enterprises need automated control equipment?
Thread Content
Yesterday I went to inspect a company that produces liquid crystal intermediates, specifically alkyl bromobenzenes. These substances are not considered hazardous chemicals, so it’s a typical chemical manufacturing enterprise. Under the four-rating-one-evaluation system, the experts inspected his distillation kettle and found it to not meet the requirements; automated control is necessary. Is there any documentation or relevant standards that require this? Looking forward to answers from experts.
Many fine chemicals now require thermal decomposition to determine their grade. However, even if it is made to meet grade one standards, automation still needs to be added. This is a basic requirement. Interlock devices may also be required for key processes.
What is thermal decomposition? Could you explain how the grading is determined? Dear
Appropriate automatic control interlock measures need to be established based on the specific circumstances. In the Shandong region, there is a document titled Lu An Jian Fa [2011] No. 140, which provides guidelines for the safety control of distillation systems
Don’t all chemical companies need to implement automated control systems?
Document No. 1 issued by the General Administration in 2017 – didn’t it set any requirements?
Could you give me a link? I’m a beginner and haven’t dealt with this before. Thank you!
Is automation also required for chemical processes that are not under strict regulatory oversight? The province provides guidance, but it’s not mandatory, right?
Distillation is not solely applied to hazardous chemical processes that are under strict supervision; the essence of automation is to increase safety levels and provide necessary convenience. This needs to be addressed based on specific processes, operating conditions, and properties of the materials involved. It is not necessary to strictly follow the relevant guidelines issued by Shandong Province or other local authorities – such documents are for reference only
