How To Decide Which Waste Gas Thermal Oxidizer Is Right For Your Process

A lot of thought needs to go into what goes up in the air.
Finland approves underground nuclear waste storage plan
2015-11-12 17:14:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Finland has become the first country in the world to give a construction license for a permanent underground nuclear waste repository, the center-right government said on Thursday. It approved Posiva Oy's plan to construct a spent nuclear fuel encapsulation plant and disposal facility at the island of Olkiluoto, western Finland. Local people have accepted the plan. Up to 6,500 tonnes of uranium may be deposited in the facility, some 450 meters (490 yards) below the surface in the granite bedrock....

Special Report: Effectively Deal With Waste Gas
2015-11-12 15:33:00| Chemical Processing
Waste gas incinerators react oxygen with waste hydrocarbons at high temperature to produce a clean flue gas. A perfect incinerator would have a destruction and removal efficiency (DRE) of 100%, zero fuel usage and zero emission of carbon monoxide and nitrogen oxides. A small amount of the original hydrocarbons always remains, though. If 1% is left, the DRE is 99%. Some CO and NOx always are produced, too. However, NOx emissions are lower for a regenerative thermal oxidizer (RTO) than for almost any other type of thermal oxidizer. With the U.S. Environmental Protection Agency and local air boards requiring DRE values from 95% upward, effectively dealing with waste gas means ensuring compliance with the added benefit of reduced energy costs. In this Special Report we take a look at how an RTO often can offer an effective and fuel-efficient options for cutting the cost of waste gas incineration, how technologies transform greenhouse gas into a feedstock for chemicals, how the right emission control system can help meet compliance and reduce energy costs and several steps that play a crucial role for setting up an effective greenhouse gas monitoring plan.
