[0019] Material formula (masterbatch):

[0020] Polypropylene: 71.5%

[0021] Polyvinylidene fluoride: 4%

[0022] Nano calcium carbonate: 3%

[0023] Fiberglass: 20%

[0024] Antioxidant (1010): 1.5% added

[0025] The packing structure is a flat plate, prepared by extrusion and calendering at 180°C

[0027] Material formula (masterbatch):

[0028] Polypropylene: 77.5%

[0029] Polyvinylidene fluoride: 6%

[0030] Nano calcium carbonate: 5%

[0031] Fiberglass: 10%

[0032] Antioxidant (1010): 1.5% added

[0033] The packing structure is a corrugated plate, prepared by extrusion and calendering at 180°C

[0034] Through the application of flat plates, corrugated plates and egg trays made of polypropylene modified coalescing materials to the oily sewage coalescing oil of Shengli Oil Production Plant Tuoyi Union Station in Shengli Oilfield, obvious results have been seen.

[0035] The test of coalescing and degreasing of oily sewage in the oil field was carried out at the Tuoyi Union Station of Shengli Oil Production Plant. The produced water at Tuoyi station contains more polyacrylamide, so oil-water separation is more difficult. The oil-water separation device for the coalescence test is 200cm long, 40cm wide, and 70cm high, with an effective volume of 0.5m 3 . The ...

Abstract

The invention relates to a coalescence material. The technical scheme is that: a polypropylene coalescence material is modified by polyvinylidene fluoride, nano-calcium carbonate, glass fibers and a 1010-antioxidant and the modified formula is formula a or formula b. According to the formula a, the mass part ratio of polypropylene, polyvinylidene fluoride, nano-calcium carbonate, glass fibers and 1010-antioxidant is 71.5%: 4%: 3%: 20%: 1.5%. According to the formula b, the mass part ratio of polypropylene, polyvinylidene fluoride, nano-calcium carbonate, glass fibers and 1010-antioxidant is 77.5%: 6%: 5%: 10%: 1.5%. According to the above formula a or formula b, the coalescence material is prepared by the steps of mixing the above components according the mass part ratio in the above formula a or formula b; mixing the raw materials uniformly at the temperature of between 50 and 80 DEG C; granulating the raw materials in a granulation machine; and drying at the temperature of between 50 and 95 DEG C after granulating so as to prepare a granular master batch of a polypropylene-modified coalescence material, wherein the working temperature of the granulation machine is between 165 and 185 DEG C; and the grain size is less than 3 mm. The coalescence material is better in balance between hydrophilic and lipophilic performances and is beneficial to the coalesce separation of oil droplets in the water.

Description

1. Technical field [0001] The invention relates to a coalescence material and a preparation method, which solves the problems of low oil removal efficiency and poor coalescence effect on crude oil in the existing coalescence material. 2. Background technology [0002] At present, most of the treatment processes used for degreasing oily sewage are three-stage methods, namely degreasing-coagulation sedimentation-filtration. The commonly used oil removal method is a two-stage oil removal method, that is, the first-stage gravity oil removal and the second-stage coagulation oil removal. Suspended solids in water can be removed while coagulating, or removed by filtration. At present, most countries and enterprises in the world still tend to adopt physical methods for oily sewage treatment. Compared with other treatment methods, the coalescence method has the advantages of simple process, small footprint, high treatment efficiency, and low cost. The oil removal process does not ne...
