A Brief Introduction to Gasification of Municipal Solid Waste

Hazardous wastes are created by almost any manufacturing process or industry. There are a myriad number of hazardous wastes that you don’t even realize are a menace for health, habitat or environment. Industries are also finding and deploying safe and eco-friendly hazardous waste disposal measures for their effective utilization and disposal. Besides reducing the production of waste material, another focus has been on safe disposal of such waste. The gasification of municipal solid waste (MSW) can be done by using various processes to convert it into a fuel or another source of energy.

Gasification of Municipal Solid Waste
Process

The MSW is pre-processed into a suitable feedstock material which is then oxidized at temperature as high as 800˚ C. The bye-product generated is a syngas which can be used as a fuel to run gas engines, gas turbines etc. The gasification of MSW has resulted in lesser demand for land under waste management and it also reduces environmental pollution.

Equipment

The reactors or gasifiers are used to convert the MSW into useful bye-products. There are fixed beds reactors which can be further categorized into downdraft and updraft design. Another type is fluidized beds which may involve using a bubbling or circulating design for efficient gasification of MSW.

Recent Technology

New technology such as plasma gasification, pure oxygen or hydrogen gasification and thermal depolymerization have been developed which are more efficient and successful.

Conclusion

It is safe to say that gasification of MSW is the need of time. The process is detail-oriented and must be carried out with adequate knowledge of the type of waste material and sustainable equipment.

Improvements in Chromium Beneficiation Process using Ball Mills

Image
Chromium has widespread uses in many industries, the primary use being the production of steel and other alloys. The industry equipment is largely dependent on steel for designing machines, therefore, the demand for chromium is always high in the market. The process of Chromite ball mill  beneficiation has many bottlenecks and needs refining with optimization of techniques. When used in combination with ball mill for grinding, the main challenges faced in chromium beneficiation are discussed below: ·          Difficulty in Separating Chromium ores are usually found in igneous rocks and are mixed with many other minerals. The siliceous ores are rich in alumina alongside chromium while ferruginous contain iron. The problem with this arrangement is the separation by crushing and grinding. The process usually requires extra steps after crushing such as gravity separation to isolate chromium. This adds to the cost of beneficiation. Also, impur...

Dynamic Separator Manufacturers in India - Chanderpur Group

Image
With the advancement in technology, the cement industry is reaching the pinnacle of success. With the ever-evolving equipment, it is getting easier for the manufacturers to undergo construction operations. Most dynamic separator manufacturers in India consider separators to be vital equipment in the industry. They are known to be extensively deployed in the cement manufacturing industry especially in the field of grinding circuits. One of the most significant functions of this equipment is to separate very fine-sized particles from coarse particles. During the separation process, the fine particles are collected at one end. They are known as finished products. On the other hand, the coarse-sized particles are returned to undergo the grinding process again. This is for receiving fine particles. One thing you must take care of is that the continuous stream of the coarse particles is checked properly. You should even take care about checking that the separated fine-sized particles are ...
