Microwaves for Chemical Pulping.


Innovative microwave wood modification technology application in pulp industry
S U M M A RY
Concept is microwave wood modification for increasing permeability in form of chips, wood pieces or logs at existing chemical pulp mills

Potential to revolutionize the pulp industry through:
Significant  reduction of chemical consumption
Increase in throughput
Significant  reduction of energy consumption
Increase in pulp quality and yield
Improvement of environmental  performance

Potential impacts

Benefits

Chemical savings (increased speed of chemical chip cooking reactions)

25-45% reduction in chemical demand, reducing load on chemical recovery processes, especially lime kiln and recover boiler

Increase in throughput

20-34% increase in throughput for digester- limited mills

Energy savings
1. H- factor reduction
2. Chemical recovery reduction

35-50% reduction in pulping energy
Up to 33% energy savings

Material savings

Reject reduction from 3.8 to 0.3%
Screened pulp yield increase  2.7%

Larger chip size can be utilised as pulping liquor is more readily absorbed

Reduction of wood loses associated with oversize chips
2% increase in pulp strength due to fewer cut fibers from chipping

Environmental aspects

Improved  environmental  performance due to  reduction of fuel use and water consumption

 

 

Disposal of waste wood.

The use of microwave energy becomes a significant relevance in the chemical processes by improving the efficiency of heat transfer, particularly in energy-intensive technologies, such as pyrolysis recycling of production and consumption. In particular, the development of technology for microwave thermolysis recycling of wood, vegetation, organic and polymer production and consumption waste already in a semi-industrial pilot phase proved high efficiency of the proposed method of disposal compared to similar products. It was found that with the combination of the traditional method of waste decomposition in a closed chamber at a temperature of 500-900 C without access to air and waste activated electromagnetic field frequency of 2.45 GHz, the total reaction time of destruction of waste is reduced by 40%, material costs for fuel (heating liquefied hydrocarbon gases) are reduced to 70%. In this case, the main practical outcome of the reaction products from the initial disposal of the waste at a humidity of 40% (by weight) is defined by the following values: 30-40% (by weight) - a carbon material, which is an analogue of activated carbon, 40-50% (by weight) - combustible hydrocarbon gases and their oxidized forms, which are fuel product, 10-30% (by weight) - liquid hydrocarbons in the tar and condensate, which are analogous to heating oil.
