Styrene storage
Thread Content
Our company has designed 50-ton stainless steel vertical storage tanks for styrene; these tanks are not buried and are located indoors. What is the maximum storage temperature for styrene? Here, temperatures can easily reach 38 degrees in summer, and it’s 30 degrees indoors as well
When storing, it is necessary to consider adding a polymerization inhibitor......
We have 2,000-cubic-foot tanks for finished styrene, equipped with circulating chilled water at 5°C and TBC as a polymerization inhibitor. The process specifications require that the tank temperature be controlled at ≤16°C.
So what about your transportation in the summer? During transportation in summer, the temperature can reach 40 degrees
We are not styrene producers; we are downstream customers of styrene

Add an appropriate amount of inhibitor, ensure proper cooling, maintain flow, and allow for fast inlet and outlet.
The storage tank should be properly insulated; if possible, storing it at low temperatures is the best option. The general storage requirement is to keep it below 20°C; with the addition of the TBC inhibitor, it can be stored safely for a longer period of time. If stored at temperatures of 30°C or above, fast intake and fast discharge should be maintained to prevent polymerization. The temperature of styrene in the storage tank should be monitored, as you are a downstream customer of styrene; the temperature of the styrene entering the tank is also important, and special attention should be paid if the temperature is high. During the summer, the content of the inhibitor should be checked regularly, and it should be added promptly if it is insufficient. The polymer content should be monitored regularly; once it starts to increase, the rise is very rapid, and it should be used or diverted as soon as possible. The flame arresters and vent valve plates of storage tanks should be inspected regularly to prevent accidents caused by polymer blockages.
Thank you for your reply. May I ask how to measure the content of the inhibitor?
If your company does not have a laboratory for testing the content of polymerization inhibitors, you can send samples to a quality inspection agency, where such tests can be carried out
A 50-ton stainless steel vertical storage tank for styrene doesn’t seem very safe when placed indoors. After all, the fire hazard of styrene belongs to Class B.
