Offshore crude oil leakage and the collection of drilling platform oil slick

the recovery and cleaning up of offshore drilling platform oil slick and the crude oil leakage of ocean tankers that may reach 2 trillion yuan in 2014 has always been a topic of research and discussion. In the face of a large number of heavy oil with high viscosity, oil-water separation is carried out. At present, the cofferdam collection method is basically adopted, and the oil slick foam granulation unit is manually completed by using PP oil absorbent felt. The unit is to collect the foam through crushing and plasticizing, strip drawing and granulation and other processes. The large flow oil slick cleaning equipment of foreign companies, electronic universal experimental machine for deformation measurement, refers to measuring the displacement of materials through the experimental machine. It is expensive. The replacement of PP oil absorbent felt produced by special processing costs millions of yuan. Therefore, the operation cost is high, the labor intensity is large, and it is time-consuming and laborious

the large flow and new floating oil cleaning equipment developed by our company can quickly and effectively separate oil and water. The operation is simple and convenient, the equipment has strong adaptability, and the replacement, maintenance and repair are simple and fast. Some filter plates can be adjusted and replaced according to the different viscosity and thickness of oil products, so as to maintain the best use effect, prolong the service life of filter materials, and enable them to be used effectively for a long time. The main components of the equipment are: 1 Oil slick recovery filter, 2 Pump, 3 Electrical control box, etc., with simple and convenient structure and low operation cost, can be widely used in the collection of floating oil on offshore drilling platforms and the recovery and cleaning of marine crude oil leakage

working principle of the equipment: when the mixed liquid containing oil and water enters the front tank of the equipment, it is first filtered through the plate, and then enters the primary oil storage tank after removing large particle impurities. The primary oil storage tank is equipped with a special plate, which can roughly filter the oil and water, and then automatically return the bottom water to the front tank of the equipment for re filtration after detection and positioning of the probe. When the floating oil on the upper part of the primary oil storage tank gathers to a certain height, it enters the secondary oil storage tank through the fixed hole. The secondary oil storage tank is mainly used for storage and standing, and the floating oil containing 10 ~ 30% water is transported to the main cabin for the second oil-water separation. Reach the oil slick collection. The single oil slick collector adopts 304 stainless steel structure, the oil slick recovery and treatment capacity is 25 ~ 100m3/h, the 380V cable control system is used, and the diameter of the oil pipeline is ∮ 80 ~ 100mm

the secondary oil-water separation system in the main cabin adopts the process of changing the water flow direction to make the oily water flow smoothly in the gap of the corrugated plate, and the floating oil will converge on the surface of the PTFE sintered membrane filter material, but will not adhere to the surface of the filter material, let alone enter the back of the filter material. When the water flow speed is controlled at about 0.5m/min, the fine oil droplet particles can be quickly captured and coalesced by the corrugated plate, and as the coalesced oil increases, The upper oil slick will gradually rise to the top of the cabin, and enter the product oil storage tank after being filtered by the hydrophobic and oil repellent plates installed on the top (different aperture specifications are selected according to the viscosity and thickness of the oil). The liquid level in the main cabin is automatically controlled and adjusted by the setting height of the drainage pipe to realize the stealth, lightweight and high strength of the above weapons and equipment. When the oil is too viscous, part of the oil diluent can be added appropriately according to its viscosity thickness to improve the fluidity of the oil, so that the oil-water separation treatment can be carried out more quickly and effectively. If possible, the heating method can also be used to heat the oil to 40 ~ 60 ℃, which can also achieve the same effect, and get heavy oil with water content less than 100ppm. (end)
