Incinerating waste produces exhaust gases laden with diverse pollutants, hitachi chimney. Different processes hitachi chimney used to remove these pollutants before the purified flue gas leaves the plant safely through the stack. For decades HZI has been doing research into flue gas treatment and developing new and effective treatment systems.

Based on the design, manufacturing, and building technologies we acquired through our experience in building ships, bridges, water gates, and ocean structures, since we have recorded building more than steel stacks in Japan and overseas and contributed to creating social infrastructure. In addition to new installations of ultra-tall stacks reaching around meters and stacks incorporating an earthquake-proof system, we can respond to customers requirements with our total engineering capabilities from design to onsite construction including repairs, reinforcing works, and diagnosis of earthquake-proof performance of existing facilities that are growing in number these days. The typical design of an ultra-tall stack is a pylon-supported stack in which the steel stack body is supported by a pylon. The pylons also serve as scaffolding for maintenance purposes, thus reducing ongoing operating costs. In the building method, which we developed before other companies, we use the jack-up method, which enables the welding of stack bodies on the ground.

HZI basically offers three different types of wet scrubber: The multiple-stage counterflow scrubber hitachi chimney the main separation of pollutants The two-stage parallel flow scrubber for separation of residual pollutants polishing scrubber The single or multiple stage condensing scrubber for extracting flue gas heat. Depending on the additive used for neutralisation we call the process: XeroSorp lime if hydrated lime is usedor XeroSorp bicar if sodium hydrogen carbonate is used.

It is difficult to define ethics precisely. Some people believe that ethics will change as society changes just as morals do. However, I regard ethics as something universal that is rooted in the inherent nature of humanity. I once asked a renowned Buddhist about the essence of ethics.

An overarching water distribution system ensures that all stages are supplied with sufficient water and that the separated pollutants are separated via the scrubber blowdown. On this basis a distinction is made between the following approaches:. The Main Advantages of the XeroSorp Process: Low operating and maintenance costs thanks to simple design and operation Low process investment and minimal infrastructure costs thanks to compact design Minimal use of adsorption additives and very low residue generation XeroSorp bicar reaches even the low BREF emission values under optimal conditions. The numerous processes that have emerged can be used individually or together to create high-performance integrated systems. It enables nitrogen oxide to be reduced to very low levels with minimal ammonia slip, something that was previously only possible with an SCR process. Fabric Filter. The Main Advantages of Adsorption onto Activated Carbon or Lignite Coke: Can easily be integrated into the various processes for removing acid gases XeroSorp, SemiDry, wet scrubber Very simple system with only a small number of components storage and conveying Proven technology with a long and successful track record in industry. SNCR Process. Mercury Adsorption onto activated carbon or lignite coke. Depending on the additive used for neutralisation we call the process: XeroSorp lime if hydrated lime is used , or XeroSorp bicar if sodium hydrogen carbonate is used. When putting together the right overall approach we take account of the following factors:. The excess can be removed downstream in a wet scrubbing process.

Chillers are ideal for large commercial and industrial buildings due to their high capacity and energy efficiency, and they eliminate noise and refrigerant risks near occupied spaces. Hitachi offers a diverse range of Chiller systems with tonnage capacities from small RT to large RT , including Air-cooled and Water-cooled, compressor types of scroll, screw, and Centrifugal Chillers, and Absorption chillers. Hitachi has global manufacturing capabilities and provides worldwide services.

We also have a track record of receiving commendations for our seismic retrofitting work. On this basis a distinction is made between the following approaches: Raw gas catalytic converter: At the boiler outlet, with upstream electrostatic precipitator Operating temperature approx.

The Main Advantages of the XeroSorp Process: Low operating and maintenance costs thanks to simple design and operation Low process investment and minimal infrastructure costs thanks to compact design Minimal use of adsorption additives and very low residue generation XeroSorp bicar reaches even the low BREF emission values under optimal conditions. Different processes are used to remove these pollutants before the purified flue gas leaves the plant safely through the stack. Type of waste, including any pretreatment Type of combustion process, plus waste throughput and thermal capacity What emission limits are to be complied with? The typical design of an ultra-tall stack is a pylon-supported stack in which the steel stack body is supported by a pylon. Electrostatic Precipitator. In our patented process, the ammonia is recovered from the effluent and can be re-injected into the post-combustion chamber. Nitrous Oxides. Each flue gas treatment module serves a specific purpose. Instead we use two different adsorption additives for neutralisation: hydrated lime and sodium hydrogen carbonate commonly known as sodium bicarbonate. SCR Process. Using a catalytic converter allows the reduction of nitrous oxides at significantly lower temperatures, and is considerably faster than the SNCR process.
