Aerogel Blanket used for Xinjiang Karamay Oilfield Steam Pipeline Use Case

Reconstruction of steam pipeline insulation in heavy oil production

----Application of aerogel blanket greatly reduces the heat loss of steam pipelines and prolongs the service life of insulation

Customer Profile of Huatao aerogel:

Company Name: PetroChina Karamay Branch

Use location: Karamay heavy oil production plant

Construction equipment / pipeline: above-ground steam pipeline

Use of the product aerogels:

Huatao HT650 aerogel blanket (10mm thickness)

Huatao HT650 Aerogel blanket (6mm thickness)

Working condition of silica aerogel:

Pipe diameter: 114mm

Internal fluid temperature: 320 ° C

Wind speed: 0.1m/s

Pipe length: 5000m

difficulty when install the insulation material:

1, the insulation layer construction plan should take into account the economic and

energy-saving, the need to use a combination of aerogel and common materials.

2, the pipe bracket must be blocked by thermal bridge treatment to further reduce heat loss.

3, the waterproof performance must be optimized.

Specific construction plan of silica aerogel insulation blanket:

Composite aerogel blanket insulation solution

(from inside and outside) 2 layers of 6mm thick aerogel blanket + 70mm composite silicate + 20mm rubber and plastic cotton + aluminum

Note when install the aerogel felt:

The 2-layer aerogel blanket is tightly wound with a single-sided aluminum foil fiberglass cloth to prevent heat leakage.

Data comparison before and after the transformation:

in conclusion:

Compared with before the transformation, the heating station of No. 3 heating station to No. 439, 440, 441 metering station was reduced: the total heat loss of support decreased by 74.1%, the heat loss of pipeline decreased by 19.5%, and the total heat loss of pipeline decreased by 33.3%.
