Acid Regeneration Process

Acid Regeneration Process The commercially most relevant field of application for HCl regeneration processes is the recovery of HCl from waste pickle liquors from carbon steel pickling lines. Other applications include the production of metal oxides such as, but not limited, to Al2O3 and MgO as well as rare earth oxides by pyrohydrolysis of aqueous metal chloride or rare earth chloride solutions. A number of different process routes are available. The most widely used is based on pyrohydrolysis and adiabatic...

Continuous emission monitoring for municipal waste incineration

Local authorities incinerate domestic waste and other kinds of waste that typically include plastics, batteries and a diversity of unknown compounds. These may all produce acidic and other toxic emissions. Therefore, efficient flue-gas cleaning systems are needed to prevent their release into the environment.

Waste water respirometry solutions for toxicity reduction tests

In industrial manufacturing companies, before a new process comes on-line, it is important to measure the toxicity of the effluent stream. This is especially the case for companies who treat their own waste. From the toxicity value (EC50) obtained, it may be a cost-effective solution to simply discharge the effluent to the treatment works at a slow and defined rate to minimise damage to the activated sludge. Following a period of acclimatisation it is often possible to increase feed rates to the plant and this...

Dust collection and odor control in waste management sites

Th turn key plant is composed by three different wet stages. The first stage is a venturi jet scrubber to collect dust and particles, then the second and third stages are deputed to absorb bad smells, such as H2S, Ammonia and Ammines. The absorption takes place thanks to the injection of chemicals (such as Sulphuric Acid, Sodium Hypochlorite and Sodium hydroxide.

Vacuum excavation solutions for fertilizer plants sector

Fertilizer Plant Clean‐up and General Maintenance. Vac‐Tron vacuum excavation models are currently being used at various fertilizer plants for general clean‐up and removal of muriatic acid waste. It is highly recommended that the inside of the debris tank and filter housing be protected with a coating that will resist the corrosive effects of the acid. Proper clean up is a must.

Air Pollution Control Solution for the FGD - SO2

Flue Gas Desulfurization (FGD) involves the removal of sulfur dioxide and other acids from flue gases. Typical sources of acid gases include fossil fuel boilers, waste combustors, and other industrial applications such as refining and smelting. The Macrotek wet and dry FGD systems can achieve over 99% acid removal by using a variety of reagents, including caustic, sodium carbonate, lime and limestone, and waste alkaline solids or liquids.

Industrial Solution for gasification & synthetic gas

Gasification and synthetic gas production from various waste products are becoming increasingly important energy recovery technologies. Often, the synthetic gas contains various hazardous contaminants including H2S, HCl and other acids, heavy metals, and tars. The gas requires cleaning before it is introduced in the engine or boiler. Most of these processes generate significant concentration of tars. The tars can vary from very low molecular weight to large and complex chains.

Plating rinse wastewater solution

Plating rinse wastewater is one of the most common applications for ENCON Wastewater Evaporators. Wastewater from plating rinse tends to be rather corrosive. The chemistries used in the plating process can include a wide range of acids such as nitric acid, chromic acid, hydrochloric acid, sulfuric acid, hydrofluoric acid, as well as other non-acid chemistries like ammonium bifluoride and nickel sulfamate. Typically, the waste stream has a transparent, relatively clean look because they are dilute and the...
