A Technology of Environmentally Clean Processing of Low Calorific Coal and Coal Waste at an Integrated Energy-Metallurgical Plants

Description

The technology ensures integrated processing of lowcalorific coal and coal waste as well as ash at fossil power plants. Interconnected installations output hydrogen, methanol, alloys, aluminium, a concentrate of rare elements, coal tar, electric energy and heat. Produced in the result of technological processing a ferrosilica- aluminium (FSA) alloy is separated into components which then can be used for methanol production. Ukraine can consume annually: 50 000 tons of FSA and 30 000 tons of by-product methanol. The estimated annual output of a commercial energy-metallurgical facility with a power capacity of 150 MWis 50 000 tons of FSA and 30 000 tons of methanol (up to 2012).

Innovative Aspect and Main Advantages

A unique technology has been developed for utilising energy resources and production waste, and the cost effectiveness of commercial processes have been improved. EPI are based on advanced processes that reduce material input for generating electric power by 15-20 %.

Areas of Application

Metallurgical industry, petrochemical industry, aviation and rocket- space industry, heat power engineering, machine building, electrical engineering, and meteorology. The technology and products are oriented to the consumer and corporate markets in Ukraine, the CIS countries, Europe, the U.S.A., south-eastern Asia countries, China and others.

Stage of Development

The technology of smelting an FSA alloy from coal waste of Ukrainian mines has been tested at a pilot industrial 2.5 MW furnace at the Nikopol’ Ferro-Alloy Plant. Currently, the conditions of pressurised electrolysis of coal sludge and separating the FSA in a high-temperature centrifuge are being checked.
