News from China Petrochemical News "Heavy-load production and hot weather, on-site gasoline, diesel, and rich gas outlet devices are generally in danger of exceeding the standard temperature
.
The air-cooling island fan is fully turned on and the temperature is up to the upper limit .
Since the fall, the barbecue mode has been activated in the southern Xinjiang region, and the surface temperature has continued to maintain above 40°C.
The Tahe Refining & Chemical Corporation, located on the northern edge of the Taklimakan Desert, has carefully deployed high-temperature summer work in summer to effectively cope with and reduce the adverse effects of high-temperature weather
.
Strengthen process management to ensure smooth operation
.
In the continuous high temperature weather, the heat exchanger load of the three sets of equipment in the first operation department of the oil refining department reached the limit, and some temperature indicators occasionally exceeded the temperature, which seriously threatened the safe operation of the equipment.
Pay close attention to the temperature of the oil product delivery device, and adjust the on-site circulating water flow rate and turn on the air-cooled spray facility in time according to the medium temperature to ensure that the equipment does not run over temperature and pressure; and require external operators to check key equipment parameters and storage tank towers.
Check the operating parameters with internal operation to ensure that the parameters are not distorted and the operation is not malfunctioning
.
Strengthen equipment inspection to ensure safe operation
.
The second operation department of oil refining carefully sorted out the high-temperature and high-load equipment in each installation area, carefully studied the key equipment and key pumps, and formulated detailed countermeasures
Team employees increase the frequency of equipment inspections, perform temperature and vibration measurement of equipment according to regulations and register them, and implement a vibration monitoring and early warning system for high-temperature pumps.
If abnormal transmission data is found, the site will be checked in a timely manner, and emergency plans will be used for emergencies.
Organize disposal
.
Strengthen management and control measures to ensure compliance with emission standards
.
The public works operation department is faced with the problem of large amount of sewage and high temperature caused by the large-load production of the installation, resulting in the decline of bacterial activity in the biochemical tank system, and the oil in the sewage may cause the oil to adhere and cover the activated sludge or biofilm, resulting in a lack of bacteria If there is a risk of death from nutrients or dissolved oxygen, the operation department will promptly add fresh water to cool down, strengthen communication with upstream devices, and adjust operations to prevent sewage from carrying oil and other measures to ensure that sewage meets the standard for discharge
Tahe Refinery conscientiously implemented the "two specials and two important" work requirements, and the competent department strictly implemented the "five inspections and five stricts" to ensure safety, and conducted in-depth on-site "inquiries" with the "four no two direct" method to affect the device under high temperature Stable production equipment "circle key" supervision, timely notification of device alarms, to ensure that safety inspections do not go through the scenes, hidden danger investigations are not mere formalities, and resolutely realize safety inspections "no blind spots, no dead ends, and no leaks" to eliminate hidden accidents Destroyed in the bud
