Management issues of sulfur storage facilities

1 The reception of liquid sulfur is scheduled in accordance with the requirements for its transportation. 2 Before receiving liquid sulfur, it is necessary to carefully check the weight certificate and the signature of the designated shipper to ensure they are accurate; any alterations must be recorded accurately and reported to the supervisor. It is necessary to carefully check whether the chain at the liquid discharge port of the tank truck is in good condition; if there are any damages, they should be repaired promptly ； If it cannot be handled during the shift, it should be reported to the workshop promptly. 3 Once the liquid sulfur hose is securely connected, inform the escort accompanying the vehicle to open the valves on the tank truck to release the liquid sulfur. It is strictly prohibited for the vehicle attendant to discharge sulfur on their own. 4 If it is found that the vehicle unloading valve or the liquid sulfur discharge pipe has frozen, it should be reported to the workshop promptly; if it is during working hours, the workshop will handle the issue according to the established procedures ； After this time, the driver should park the vehicle properly and connect the insulated steam supply. 5 After all the liquid sulfur has been drained, it is necessary to go to the tank truck to check and confirm, and then inform the escort to close the valve tightly; only then can the hose connection be removed. At the same time, use a special cap to seal the outlet of the liquid sulfur pipe, and secure it tightly with an iron chain. 6 While discharging liquid sulfur, it is necessary to closely monitor the actual liquid level in the underground tank to ensure that the liquid sulfur does not overflow. Several points need attention here: a) If the speed at which one pump can transfer liquid sulfur is not fast enough to keep up with the unloading rate, it is necessary to control the unloading pace. b) If two pumps are used for transferring liquid sulfur, it is essential to properly adjust the opening positions of all valves in the liquid sulfur pipeline. c) The liquid level in the underground tank must not drop below one meter; the pump must not run dry. d) While the pump is in operation, no one should leave the storage area. e) After stopping the pump, the outlet valve of the pump must be closed to prevent the pump from running in reverse or to avoid siphoning effects. It is also necessary to fill out the daily report on liquid sulfur carefully, and the recipient must sign the weight measurement sheet. Record the liquid levels of each storage tank, as well as the number of receiving vehicles on duty, their vehicle numbers, and the numbers of weight certificates. 8 The receipt and storage of liquid sulfur are the responsibility of the receiving shift ； The transportation (or dispatch) of liquid sulfur is the responsibility of Shift 9; the liquid level in each storage tank must be recorded every shift ； Every day, it is necessary to check by comparing the cumulative value indicated by the flow meter (i.e., the amount used) with the height of the stored liquid sulfur (i.e., the amount stored), in order to determine the relationship between intake, output, and storage. 10 Under normal operating conditions: the refined sulfur tank pump is always on, the shielded pump is always on, and the underground tank pump is turned off intermittently. 11 It is strictly prohibited to allow the liquid sulfur tank to discharge liquid sulfur into the refined sulfur tank while simultaneously injecting liquid sulfur into that tank, in order to avoid measurement confusion. 12 The liquid sulfur temperature in each storage tank and the level of the refined sulfur tank must not, without reason, be lower than those of the previous shift. 13 Inventory checks of the storage levels are to be conducted at the end of each month ； Calculate the quantities received and dispatched, the number of vehicles, production consumption, inventory levels, and losses. 14 Daily, routine inspections of the area must be carried out, with the following items to be checked:  The opening and closing status as well as the flexibility of each valve on the liquid sulfur delivery pipelines  Whether the seals on the liquid sulfur hoses and steam hoses are in good condition  The operating status of the pumps, whether the current levels are normal, and whether the cooling water is functioning properly  Whether there are any leaks in the steam pipelines and valves ； Is the exhaust from the hydrophobic pipeline abnormal? ； Is the drain valve functioning properly?  Is the vent on top of the liquid sulfur storage tank blocked by liquid sulfur? 15 It is necessary to maintain good hygiene in the area and on the equipment:  The areas above and around the underground tanks, around the large liquid sulfur storage facilities, and within the enclosure surrounding the shielded pumps should be kept clean at all times ； Water flushing is prohibited on the top of the geosyncline.  The control room should be clean and tidy, free of clutter, with tools neatly arranged. The area outside must be kept clean, free of cigarette butts and debris. Any sulfur that falls off the liquid sulfur tank or leaks during sulfur discharge must be dealt with promptly, and all waste on site should be placed in bags.  The drainage ditches and manholes on site must be kept clear to the bottom, and it is strictly prohibited to leave cigarette butts in them. 16 The liquid sulfur storage area is a flammable and explosive environment, so all of the company’s safety regulations must be strictly followed ； Ensure proper safety and fire protection measures, as well as maintain the cleanliness and functionality of fire protection equipment ； In addition, there is also a responsibility to prevent any illegal activities by outsiders in the area.

1# zx9527007: My collection workshop is a facility that uses solid sulfur as raw material. I would like to say the following regarding this: The sulfur storage area should be well-ventilated; in principle, all doors and windows should be kept open (they should be closed on rainy days to prevent rainwater from entering). Axial flow fans should be installed on the walls to create convection. These fans serve two purposes: first, to prevent sulfur dust from accumulating to an explosive level, and second, to lower the ambient temperature and thus prevent the sulfur from catching fire on its own； Install explosion-proof monitors to detect potential hazards in a timely manner ； Install automatic combustible gas alarms, with remote monitoring in the central control room of the operation area; the signals are connected to the fire department ； Regularly remove solid sulfur dust that settles on the ground to ensure intrinsic safety ； The storage sites are equipped with fire-fighting equipment, such as wall-mounted fire hydrants, dry powder fire extinguishers, fire steam systems, and fire steam spray devices designed for sulfur liquid storage tanks ； Regularly check the condition of the aforementioned fire protection facilities, and maintain a dynamic record sheet. Steam pressure should be included in the operation records as an important process parameter to be monitored in real time.

What is an explosion-proof monitor, and is it effective?

What are the specific considerations for solid material unloading? For example, when transporting it by truck from the port to the warehouse at an average rate of 70 tons per hour, how should the process be designed in detail? Key operational points?
