The application of nanoporous aerogel thermal insulation to petrolchemical industry
          Nanoporous aerogel thermal insulation is mainly used for heat preservation in the pipes for high temperature gas injection mining of heavy oil, gas production in gas fields and refining units, with medium temperature between 280℃ and 500℃. The nanoporous aerogel thermal insulation mat is so thin and light that it will reduce the quantity of the mat when applying to the target area , but it will achieve an excellent result. The  mat enjoys high drainage and its hydrophobic ratio is 99%, its chlorine ion content  can meet the standard requirement of China and it won’t corrode the pipes for thermal pipes so as to prolong the lifetime of the construction objects and reduce the cost of maintaining . To achieve the same thermal result, nanoporous aerogel insulation mat can reduce the total volume of the construction objects and then increase the arrangement rate.        

          aerogel insulation mat used mainly for thermal heavy oil high temperature steam pipe insulation and refinery pipeline medium, usually at a temperature between 200 DEG ~600 deg. Aerogel thin products can effectively reduce the amount of external insulation layer, so that the overall cost is reduced, and it has excellent hydrophobicity and hydrophobic rate greater than 98% and the pH value is neutral, no corrosion of pipe insulation, thus prolonging the service life of construction object, and reduce the cost of maintenance. The same insulation effect, using the aerogel insulation mat can effectively reduce the construction of the object size, thereby significantly improving the rate of pipeline arrangement. Now the industrial transmission heating pipe, the temperature inside the pipeline from a few degrees to 600 degrees have. The pipeline insulation engineering widely used aluminum silicate magnesia materials, glass fiber materials. About 30 years ago, almost all of the insulation works also just rock wool, mineral wool materials, up to now, in the industrial rock wool insulation insulation engineering, has been eliminated. In the construction performance, waterproof performance and other aspects are not the case, the main reason is to eliminate the thermal conductivity gap.

●The thermal insulation structure is unreasonable, the insulation thickness is not standard, the insulation construction is not in place. 
●The utility model has the advantages of easy deformation, sedimentation, poor thermal stability, large breakage rate, poor heat preservation effect in the late period, and can not meet the technical requirements. 
●The effect of heat preservation is poor and decrease obviously, which leads to the increase of maintenance cost and the increase of equipment operation cost. 
●Service life is only 3 to 5 years, the expiration of the need to replace all. 
●Not completely waterproof, easy to absorb moisture corrosion pipeline. 
●For more than 100 degrees of high temperature pipeline, insulation layer needs at least >200mm thickness, pipe line high heat flux, heat loss. 
 Benefits of aerogel materials:
●The heat insulation effect is 2-5 times that of the traditional heat insulation material, the advantage is more obvious at high temperature, and the service life is longer. 
●The material is hydrophobic, which can effectively prevent water from entering the pipeline and equipment, and has the A1 grade fireproof performance. 
●The utility model has the advantages of light weight, easy cutting and sewing, and the utility model is suitable for various pipelines and equipment with different shapes. 
●Less package volume and lighter weight can greatly reduce the transportation cost of insulation materials. 
●Meanwhile, the utility model has the functions of sound absorption, noise reduction, buffering vibration, etc., and can improve the environmental quality and protect the equipment. 
●Only the thickness of 1/2 to 1/5 can achieve the same heat insulation effect of traditional materials, the heat loss is very small, the space utilization rate is high.
