Pipe blockage

The actual pipeline and process conditions are currently unknown. It is recommended to first identify which point the issue lies at (this depends on whether there are reserved ports and isolation valves in different sections). ) If it can be determined the approximate range, appropriate actions can be taken based on the actual situation. If the oil has frozen and blocked the pipes due to low temperatures, it is recommended to pour warm or hot water over the pipes and then gently tap them. If it is an entire pipeline, it is recommended to check whether pressure can be applied (without exceeding the valve’s pressure tolerance), and then gently tap on the pipeline. These are just general directions; it needs to be adjusted according to the actual situation. Solve the problem first, and then take preventive measures based on this experience to avoid similar situations from occurring again

First, it is necessary to determine the diameter of the pipes, the name of the material along with its physical and chemical properties, the length of each section, and the total length. It’s better to send this information up so we can discuss it. Otherwise, it is like a blind man trying to touch an elephant.

Thermally melt it; if the pipeline is not long, remove the entire section and take it to a safe distance to use a more secure method

The main component is ethylene glycol, with some elements similar to diglycol present as well

Feed line of distillation tower; vacuum tower – can it not be pressurized?

The feed line to the distillation tower can’t be removed

If it’s time to shut down the tower, then do so. After the pandemic, our company also experienced prolonged periods of shutdown; now, when operating the equipment, many pipelines get clogged. It’s necessary to shut it down when needed, and resume production once the issues are resolved
