Purchased PPH winding tank Then, the next work to be done is to arrange the PPH winding tank. However, as PPH wound storage tank is mainly used to store chemical substances, there are also requirements for the layout of PPH wound storage tank for safety reasons. What are the specific requirements? Let's get to know.
The grouping of the tank farm shall fully meet the requirements of the overall process flow of the whole plant and the overall layout of the warehouse of the whole plant.
Generally, the PPH winding tank farm should be placed in a separate area. However, it can be placed in the same area with the relevant oil pump room to shorten the length of the pipeline between the PPH winding storage tank and the pump room, reduce the friction loss of the pipeline, and facilitate oil pumping. Control surface of pump and oil tank farm. The cable is led to the nearby control room (the operator duty room and the tank farm external control room are generally the same building as the pump room), which is also more convenient for the operator to check the operation.
Frozen or non frozen liquefied petroleum gas tanks shall be installed in places with good ventilation and drainage.
When determining the elevation of the foundation surface of the PPH winding storage tank area, it shall fully meet the requirements of the net suction head of the pump in the pump room.
The height from the low point of the spherical tank to the ground shall be at least 1.5m to maintain good ventilation around the spherical tank. For bottom outlet spherical tanks, this height should be considered together with the net positive suction head (NPSH) of the pump before making a decision.
Raw material tank farm and intermediate raw material tank farm shall be located as close as possible to relevant production equipment. The planned ground elevation of the tank farm shall be equal to or equal to the planned ground elevation in the production equipment. In order to shorten the water inlet pipeline from the tank farm to the raw material pump of production equipment as much as possible, reduce friction loss, ensure that the raw material pump of equipment has a satisfactory net suction head, avoid pumping, and ensure safe and reliable continuous production of production equipment. Set the material pump of the production equipment outside the production equipment.
The orientation of the product tank farm should be as close to the oil injection equipment as possible. When the oil pipeline is shipped, the product tank farm should be as close to the first station of the export pipeline as possible to meet the requirements for outbound transportation of products in a timely manner.
chemical PPH storage tank The area shall be placed close to the unloading equipment, and shall be placed in the same area with the chemical delivery pump room. If chemicals are transported into the plant area by truck tankers, chemical PPH winding storage tank area, pump room and unloading truck can be placed in one area, such as alkali liquor, acid liquor and ammonia liquor.
The additive tank farm shall be close to the equipment using additives, such as lubricating oil additives.
The startup oil and slop tank area shall be placed near the production equipment that can treat slop oil, such as atmospheric distillation equipment and catalytic equipment, so that the recovered slop oil can be collected and recycled in time.
