Gas treatment plant exhausted by Ärdal “Hydro Aluminium”, Norway

Gas treatment plant exhausted by Ärdal “Hydro Aluminium”, Norway

Project starting year: 2012
Project completion year: 2013

Contracting Authority: Alstom Power Norway
Beneficiary: Hydro Aluminium AS Ärdal Norway
Partnership:
Alstom Power Norway: design and procurement
ENERGOMONTAJ S.A.: in charge of manufacturing and erection works

Location:
“Hydro Aluminum” is located in Ärdal – a traditional district of Sogn og Fjordane, in the central-western area of Norway.

Main technical characteristics:
The factory is located within Hydro Aluminum Works, Ärdal, thus being the second largest Norwegian plant of such type and having a production capacity of 321 000 tons/year. The plant is using the bauxite extracted from a nearby mine and the bauxite from other mines, which is transported to the Works harbor from the nearby fiord.

Scope:
The filtering installation is provided for a hall where the aluminum is produced in 64 reduction pots, each having a capacity of 16 tons. The gas is collected from each reduction pot through 2 small channels converging into a channel (L: 2.2 m x h: 1.5 m). At present, the plant is provided with 5 identical filters, each with a ventilator driven by a 2 kW motor. Under the maximum capacity, such ventilator is able to circulate an air volume of 500 000 m3N/h.
The air entering into the filter is polluted with sulfur dioxide and alumina powder, this being the reason why both mechanical and chemical filtering methods are used.

The filters being used in the above-mentioned plant are using 3 filtering methods:
Filtering by cyclone filter – the reactor (vortex filtering), is in the lower side of the filter and practically, the gas from the filter supply channel is directly introduced in this reactor, that is provided with a series of elements which are modeling the air flow into a vortex. This filtering procedure is filtering the less fine, high grain particles (higher than 5-6µ).
Filtering by fabric bags is carried out in the middle part of the filtering installation, over the bunker where the alumina powder resulting from both the cyclone filter(reactor) and the bags which are blown with compressed air once these are loaded with too much dust.
Gas washing with caustic soda (NaOH) and water solution, which is carried out in the absorbers installed after the centrifugal ventilator which is transporting the gas from the bag filter into the absorber where the chemical washing is carried out.

The detailed technical solutions of the Romanian designers have been focused on the following categories of works included in the gas treatment installation:
– Electrical and automation installation works
– Sewage and water outer networks
– FRP and PP ducts fabrication and installation works
– FRP smoke stack installation works
– Execution/erection works for thermal insulations and electrical heating systems for technological ducts
– Erection works for the ventilation installation at the limestone unloading station
– Erection works for the limestone unloading station

ENERGOMONTAJ S.A. was the general contractor of the erection works for:
– the structural frame and the case of the filters
– the main equipment of the filters (air ventilators, alumina powder pneumatic transport installation)
– pipe circuits (stainless steel) – including the design, afferent to the desulphuration installation of the filtering installation
– reaction tank (stainless steel)
– lye intake circuits
– measurement and control equipment, compressed air circuits and drives
Assistance for commissioning

The fabrication
of steel plate walls reinforced by mounting frames; installation support structure; mechanical components of the bag filters, silos, stainless steel bunkers and tanks afferent to wet desulphuration installation (most of them made of stainless steel) attached to the filters was carried out within ENERGOMONTAJ S.A. workshops in Bucharest.

Main technical characteristics:
Govora Thermal Power Plant is located in the industrial area, 12 km South of Rm. Vâlcea city.
Govora TPP is producing electrical energy and heat under the form of industrial steam for the chemical area units; thermal agent for heating and hot water in Rm.Vâlcea and also treated water, as thermal power carrier agent.

The objective is including:
– 2 (two) boilers operated with natural gas and having the following specifications: 420 t/h at 140 bar and 550 degrees C (or oil fuel operated under partial loads);

Energy resources:
Classic fuels (coal – lignite extracted from Berbesti Area, natural gas and oil fuel).
The assembly of the desulphurization installation for Boiler no.7 of Govora TPP was designed in accordance to the Contract signed with the Client, for the purpose to limit the sulphur dioxide (SO 2) emissions at maxim 160 mg/Nm3, when the fuel being used is 97 % lignite and 3% natural gas, ash emissions are below 24 mg/Nmc.

The desulphurization process consists of:
– reduction of flue gas (SO 2) emissions;
– reduction of other pollutants (dust, hydrochloric acid, hydrofluoric acid);
– through the reaction of the limestone powder (CaCo 3 ), with (SO 2 from the flue gas, this is eliminated and the gypsum is formed as a residual product.
