In the petrochemical industry, aluminum silicate fiber module is widely used for heat preservation and insulation of various high-temperature equipment because of its excellent heat insulation performance, high temperature resistance and chemical stability. The following is its specific application in petrochemical industry:

I. Cracking furnace

Cracking furnace is the key equipment used in petrochemical industry to produce ethylene, propylene and other chemical raw materials. Its working temperature is extremely high, and it usually needs to withstand the high temperature above 1200℃. The high-purity and zirconium-containing aluminum silicate fiber modules are widely used for furnace lining insulation of cracking furnaces because of their high temperature resistance (high-purity and zirconium-containing modules can reach 1300℃ and 1400℃). These modules can effectively reduce the heat loss, improve the thermal efficiency of the cracking furnace and prolong the service life of the equipment.

II. Reforming furnace

Reforming furnace plays an important role in natural gas conversion, synthetic ammonia and other processes, and its working temperature is usually between 1000℃ and 1200℃. The aluminum silicate fiber module can provide good heat insulation effect for the reformer, reduce heat loss and improve energy utilization efficiency. Its low thermal conductivity (0.050-0.060 W/(m k) at 200℃ and 0.095-0.120 W/(m k) at 400℃) ensures the stability of thermal insulation performance.

III. Atmospheric and vacuum furnace

Atmospheric and vacuum furnaces are used for atmospheric and vacuum distillation of crude oil, and the working temperature is generally between 400℃ and 600℃. Aluminum silicate fiber module can effectively insulate heat and reduce heat loss, and its good chemical stability makes it resistant to the corrosion of chemical media produced during crude oil distillation.

IV. Coking furnace

Coking furnace is used in the production of petroleum coke, which has high working temperature and needs to withstand the double tests of high temperature and chemical medium. Zirconium-containing aluminum silicate fiber module is widely used in lining insulation of coking furnace because of its excellent high temperature resistance and chemical stability.

V. High temperature pipeline

High-temperature pipelines in petrochemical industry need reliable insulation materials to reduce heat loss and prevent the influence of heat on the surrounding environment. Aluminum silicate fiber module is widely used for heat insulation of high temperature pipelines because of its light weight, high strength and excellent heat insulation performance.

VI. RTO thermal storage incinerator

RTO (Regenerative Thermal Oxidation) furnace is used to treat waste gas produced by petrochemical industry, which has high working temperature and needs to tolerate frequent temperature changes. The thermal shock resistance and high temperature stability of aluminum silicate fiber module make it an ideal thermal insulation material.

VII. Other high-temperature equipment

Aluminum silicate fiber module is also used in other high-temperature equipment in petrochemical industry, such as heating furnace, reformer, high-temperature decomposition pipeline and so on. Its low thermal conductivity, low thermal capacity and good thermal shock resistance enable it to effectively reduce heat loss and improve the thermal efficiency of equipment.

To sum up, aluminum silicate fiber module is widely used and important in petrochemical industry. Its excellent thermal insulation performance, high temperature resistance and chemical stability make it an ideal thermal insulation material for high temperature equipment in petrochemical industry.
