Ducon Infratechnologies Ltd was incorporated under the Companies Act, 1956 as a Public Limited Company on April 2, 2009. The company is mainly engaged into the businesses of engineering, procurement and construction (EPC). It is a leading manufacturer of Flue-gas desulfurization (FGD) systems in India. Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) from the exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes. This process is carried out during combustion in fossil fuel power plants such as coal and oil red combustion units. When coal or oil is burned to produce energy, about 95% or more of the sulfur is generally converted to sulfur dioxide (SO2) under standard temperature conditions.
FGD can be characterized into wet & spray dry scrubbing, wet sulfuric acid process, SNOX flue gas desulfurization and dry sorbent injection system based on methods of desulfurization. Most FGD systems employ two stages: one for fly ash removal and the other for SO2 removal. In wet scrubbing systems, the flue gas normally passes first through a fly ash removal device, either an electrostatic precipitator or baghouse, and then into the SO2-absorber. However, in dry injection or spray drying operations, the SO2 is first reacted with the lime, and then the flue gas passes through a particulate control device. Another important design consideration associated with wet FGD systems is that the flue gas exiting the absorber is saturated with water and still contains some SO2. These gases are highly corrosive to downstream equipment such as fans, ducts, and stacks. Application segments of flue gas desulfurization market include new FGD systems and reagents & replacements.
Some of the major companies in global flue gas desulfurization market include Alstom S.A., Babcock & Wilcox, Siemens Energy, Thermax, Ducon Technologies Inc., Hamon Research-Cottrell, Mitsubishi Heavy Industries, and Marsulex Environmental Technologies. Other companies include China Boqi, Chiyoda Corporation, Hitachi Power Systems America Ltd., Marsulex Environmental Technologies and Lonjing Environment Technology Co. Ltd.
Globally, Ducon has supplied wet FGD systems on over 20,000 MW of combined power plant capacity. Ducon FGD systems can achieve over 99% sulfur dioxide removal e?ciency. Ducon Flue Gas Desulfurization systems can also recover up to 90% of oxidized mercury in the flue gas. It can select a packed tower, a spray tower or a Ventri-Rod Absorber ( VRA) (a proprietary Environeering unit) for the wet FGD application. For Dry Flue Gas Desulfurization systems, Ducon uses its proprietary two-fluid nozzle DRX-25 to atomize feed slurry in the spray reactor. It can also provide a Circulating Reactor Dry FGD System suitable for applications of upto 3% sulfur coal and by utilizing dry lime, it can provide upto 97% SO2 removal e?ciency. Ducon works with reputable vendors to provide Gas-to-Gas heat exchangers, fans, controls, and reagent handling & feeding systems. It has the capability to provide a complete global turnkey installations including e?uent treatment systems.
Ducon has the capability and technology to design the most e?cient dense phase conveying system with capacity as high as 300 TPH and conveying distance in excess of 1500m.
With many firsts in its stride, the company is rightly regarded as the pioneers of FGD in India. The company has installed India`s first Sea water FGD system with 100% of ue gas, for 2 X 250 MW DahanuTermal Power Station for Reliance Energy Ltd. This unit consistently ranks among the cleanest as well as the most reliable power generating station in India. This project also disproved the notion that energy production and environmental protection are mutually exclusive. Ducon is also credited with providing India`s rst Wet limestone FGD system on coal red power plant with production of salable Gypsum for 2 x 600 MW Udupi Thermal Power Station, Karnataka. Today this unit has become benchmark installation for those desirous of installing FGD systems in India. India`s first ever Dual Alkali Scrubber for Sterlite Copper, Toothukudi, Tamilnadu and FGD system for Glass Furnace at Saint Gobain Glass, Sriperumbudur, Tamilnadu is provided by the company respectively.
Ducon with its technology specializes in the design, supply, installation of complete turnkey facilities for Bulk Material Handling
and Pneumatic Conveying Systems. It supplies systems to unload, store, reclaim, weigh and sometimes process materials of all kinds of Power, Cement, Steel, Alumina, Chemical and Petrochemical industries.
The company o?ers pressure pneumatic conveying system for conveying of various powdery material like Cement, Clinker dust, Sand, Coal, Alumina, Bentonite, Fly ash etc. DU-PUMP systems can operate at higher air to solid rations and it has many advantages like positive pressure system, low velocity, less erosion of pipes and bends. DU-SLIDE Conveyors are used to convey the material from one point to another via air. It is ideal for materials such as Fly Ash, Cement, Hydrated Lime, Alumina, Barites and Flour etc. The aeration of the material causes it to act like a uid and gently slide along the gradual slope of the slide.
The company provides material extraction systems for at button and conical bottom silos for using reverse udized cones and opentop-slide
conveyors. The centre cone is udized constantly whereas the radial side conveyors on silo bottom are operated sequentially for systematic extraction of material from silo. Today, as an EPC company, Ducon has executed multiple Dry Bulk Material Handling systems over the last one decade. The company is also credited with First ever Pipe Conveyor in Aluminium Industry at Hindalco Industries Limited - Mahan Aluminium, Singrauli, Madhya Pradesh and Aditya Aluminium, Lapanga, Orissa.
In December 2014, Ministry of Power launched the Deen Dayal Gram Jyoti Yojana (DDUGJY) which subsumed RGGVY. The main object of the scheme was to ensure 100% rural electrication on targeted manner. It also involved improving sub-transmission and distribution infrastructure in rural areas.
In 2015, the Central Government launched the Integrated Power Distribution Scheme (IPDS) with the objective to provide 24/7 power for all. One of the flagship programmes of the Ministry of Power, IPDS aims at strengthening of sub-transmission network, and also the metering, IT application, Customer care services and the completion of the ongoing works of Restructured Accelerated Power Development and completion of the Reforms Program (RAPDRP).
During the financial year 2020-21 , the Company had allotted 5,70,00,000 Equity shares of face value Re. 1/- each at an issue price of Rs. 5/- each (including a premium of Rs. 4/- each) and 5,96,34,400 Warrants convertible into Equity Shares of face value Re. 1/- each at an issue price of Rs. 5/- each (including a premium of Rs. 4/- each), to Mr. Arun Govil, Managing Director and Promoter of the Company, on preferential basis, on 1st February, 2021, by way of conversion of outstanding unsecured loan. The company had also allotted 1,50,00,000 Equity Shares of face value Re. 1/- each at an issue price of Rs. 5/- each (including a premium of Rs. 4/- each), to Mr. Atul Kumar, falling under public category, on preferential basis, on 1st February, 2021, by way of conversion of outstanding unsecured loan.
The new Saubhagya Scheme (Pradhan Mantri Sahaj Bijli Har Ghar Yojana) seeks to ensure universal household electrication, is, in both rural and urban areas. Under this scheme, the identied poor households will get free electricity connections.
The company is presently executing Rural Electrication under DDUGJY scheme and Urban Electrication under IPDS scheme. This is the new segment which Ducon has diversied into. The projects involve, Construction of new 33 / 11KVA sub-stations, Augmentation of 33/11KVA sub-stations, New 33 KV lines, New 11 KV lines, Metering, etc. The company plans to expand the volume of this segment in future.
