Embodiment
[0036] This embodiment is used to illustrate the specific process of treating the sludge by using an integrated treatment method for cleaning the sludge in the FPSO oil tank of the present invention.
[0037] The FPSO oil tank sludge cleaning and integrated treatment method of the present invention is specifically implemented through the following steps:
[0038] S1. Preliminary preparation: Degas the oil tank to be treated, use more than two fans to supply air to the cabin, and keep the oil measuring port and gas measuring port open to intensify the gas disturbance in the tank to speed up degassing;
[0039] S2. The emulsified water layer is processed: as figure 1 As shown in the flow chart, the emulsified water in the oil tank is pumped to the grease trap on the deck, and the aeration in the grease trap promotes the separation of oil and water, and the upper layer of oil is scraped into the oil with an oil scraper. Treatment tank, heat the oil in the oil treatment tank to 8...

The invention discloses an FPSO oil tank polluted oil sludge clean integrated treatment method. According to the method, by virtue of an integration technology, emulsifying water is directly treated on FPSO and treated water can reach the standard to be discharged; hard polluted oil sludge at the bottom layer of the oil tank is cleaned out of the oil tank by virtue of an automatic sludge discharge device and is further treated so that 60-95% of oil products in the hard polluted oil sludge can be recovered; and gases such as oil gas produced in treating the oil tank polluted oil sludge are absorbed by virtue of a gas absorption device. By the FPSO oil tank polluted oil sludge clean integrated treatment method provided by the invention, the FPSO oil tank polluted oil sludge treatment efficiency is increased, the operational risk is decreased, the oil product loss is decreased and the clean integrated operation is achieved.
Description
technical field [0001] The invention belongs to the field of cleaning treatment of offshore production facilities, and in particular relates to an integrated cleaning treatment method for FPSO oil tank sludge. Background technique [0002] As the second largest energy consuming country in the world, my country's national energy development continues to expand, and oil energy development has developed into the deep sea. FPSO (Floating Production Storage and Offloading) is a floating oil storage and offloading device, which is a floating offshore platform that adopts mooring operations. It has become the mainstream way to develop offshore oilfields. [0003] For the oil storage capacity of FPSO in my country, most of them are 100,000 m 3 to 230,000m 3 In the meantime, after the oil storage tank has been in operation for a certain period of time, the organic substances with high density and high viscosity, such as mud, water and oil residue in the oil product, will continue ...
