Recently, Maoming, a coastal South China Sea, received frequent reports of typhoon warnings, although the succession of typhoons did not favor Maoming this piece of blessed land, but the hot and humid weather has been going on for the people of Maoming Petrochemical styrene, boredom Not only because the weather is hot, but more because the hot weather led to a decrease in the vacuum of the ethylbenzene dehydrogenation unit, resulting in a low conversion of ethylbenzene and ultimately a decrease in the yield of styrene products.
Maoming Petrochemical styrene workshop workshop first of all required the main operation of the monitoring to be strict and strict, for the alarm indicator must be confirmed within 5S, every 20 minutes read a DCS operating curve, every 2 hours to record the parameters of operating data, Eliminate the false alarm led to the staff to reduce the awareness of prevention, so that the indicator in the operating range, to prevent over-index caused by the process of interlocking; foreign operations must ensure that 1/3 the number of people on duty in the on-site inspection, food and pay During the succession to have someone on-site inspection, to ensure that all-round, all-weather on-site inspections are carried out in the event of an emergency situation can rush to the emergency site for disposal at the first time.
