Microwave sterilization of large microwave equipment is the result of the combined effects of thermal and biological effects of electromagnetic fields. The thermal effect of microwaves on bacteria is to denature proteins and cause bacteria to lose nutrients, breed and survive. The biological effect of microwave on bacteria is that the microwave electric field changes the permeability of the cell membrane section. The bacteria are therefore malnourished, cannot be normally metabolized, the bacterial structure is disrupted, and the growth and development are inhibited and die.

Application of large microwave equipment to the petroleum industry

The application of large-scale microwave equipment in oil exploitation, transportation, smelting and chemical industry will have great development prospects. In the exploitation of crude oil, microwaves can be used to mine heavy oil and high-condensation crude oil. Due to the high viscosity of these oils, it is difficult to adhere to sandstone. Mining is carried out using conventional water flooding methods, while other methods are costly and inefficient. The application of microwave technology is an effective method to solve these problems.

Microwave action on heavy oil will cause microwave chemical changes and microwave thermal effects. It not only changes the wettability of the rock, improves the sweeping system, improves the oil recovery, but also acts due to microwave during the mining process. The thermal effect and non-thermal effect make the asphaltenes be converted into light oil with small molecular weight during the mining process, which can save the heavy oil conversion process in refinery.

Save a lot of investment, microwave in the development of oil and gas fields and other applications such as: microwave demulsification, microwave desulfurization, dewaxing, microwave deblocking and microwave to prevent the formation of hydrates in natural gas and so on. In the petrochemical coal industry, microwaves are used to excite methane gas phase cracking, microwave petroleum distillation, and plasma gasification of coal.

The heating in the hydrolysis process of polyacrylamide by microwave heating, due to its poor thermal conductivity, the heating method is slow by ordinary heating method, and the inside and outside is uneven, which seriously affects the product quality and production efficiency, and the microwave heating property is utilized. Its penetrability allows for rapid and even heating of the product and uniform heating. Greatly improve labor efficiency and product quality, saving energy and reducing consumption. The economic benefits are significant.
