Background: INTRODUCTION: The Hungarian Petroleum industry company Tisza, is now using modern technology to dispose of damaging refinery waste. Until recently, tons of environmentally hazardous mud had contributed significantly to pollution in the Leninvaros region, but the new process has the approval of the most dedicated conservationists.
SYNOPSIS: The technological processes at the Tisza complex in Leninvaros are vast consumers of fresh water, and the greater part of the two-thousand cubic metres (440-thousand gallons) necessary every hour, emerge heavily polluted. Holding tanks close to the refinery are used to store the contaminated water where the pollutants are allowed to settle.
The pollutants collect at the bottom of tanks as an oil-saturated mud. Until recently, the mud was allowed to collect until it almost choked the bed of each pool, then was transported to segregation vats where it dried. That last phase caused problems, and eventually, criticism. Tests showed the drying areas were leaking contaminated liquid into the environment, literally poising in the land. But these days, by-products are destroyed before they can cause damage.
The secret of this environmentally acceptably refinery is a technical breakthrough which allow the oily mud to be burned at superheated temperatures.
The burner, unique in Hungary, consumes the mud at between one-thousand and 11-hundred degrees centigrade (1,850 to 2,000 degrees Fahrenheit). A device known as a rotator removes most of the water before burning and the system is now destroying between 20 and 30 thousand cubic metres (700,000 to 1,050,000 cubic feet) of the fouled mud a year, as well as conventional waste like paper, wood and cloth. Water from Tisza is almost drinking quality and certainly harmless when released into the environment.
