gas steam generator Applications

  • Power Generation

    Combustion turbines A gas turbine, also called a combustion turbine, is a type of internal combustion engine. It has an upstream rotating compressor coupled to a downstream turbine, and a combustion chamber in-between. The basic operation of the gas turbine is similar to that of the steam power plant except that air is used instead of water. The turbine shaft energy is used to drive the compressor and other devices such as an electric generator that may be coupled to the shaft. The energy that is not used for shaft work comes out in the exhaust gases, so these have either a high temperature or a high velocity. A catalyst is often used to treat these exhaust gases to comply with emissions regulations. EmeraChem has installed OEM and after-market catalyst in over 240 applications

    Thermal waste gas purification of siliceous organic compounds

    The cleaning problem of the heat exchangers was solved. The contaminants were destroyed efficiently and economically while steam for the production process was generated at no additional cost.

  • High performance separation system for ethylene industry

    Fundamental building block chemical used in the production chain of polyethylene, PVC, styrene, ethylene glycol, vinyl acetate, linear ∂-olefins and a host of other chemical products. Eliminate hydrocarbons in Quench Water system, minimize fouling, provide greater system reliability, lower maintenance, lower energy costs. Quench water contains emulsified heavy aromatic hydrocarbon (SG = 0.975). Cracked hydrocarbons are extremely reactive. Polymerization leads to fouling of quench system, exchangers, dilution steam generator. Fouling reduces plant profitability and on-stream reliability.

  • Air pollution control for the waste gasification industry

    Processes that create a synthetic gas (syn gas) in a gasification process for waste reduction, electricity generation, or steam production (CHP – combined heat and power processes) – commonly benefit from custom heat recovery systems.

  • Moisture Monitoring for Nuclear Reactors

    The Advanced Gas Cooled Reactor uses carbon dioxide gas to transfer heat from the nuclear fission core to the water boiler for steam generation. The moisture content needs to be monitored to avoid corrosion damage, and continuous moisture monitoring acts as a boiler leak detector or bulk moisture meter.

    Applications and Air Pollutants Removed in the Biomass Industry

    Flue gas particulate and acid gases from biomass and bagasse boilers. Removal of ethanol, CO2 scrubbers and yeast cells from fermenters.  Removal of ash particulate, tars, acid gases and ammonia from steam reformers, gasifiers, pyrolosis units and cooling of syngas streams to acceptable limits to enable use as a fuel source for power generation or as a feedstock for chemical products. For tar removal, combination technologies can be used including oil based scrubbing solutions to reduce waste water generation. Ethanol and yeast cell removal from fermenter off-gases. Methanol from processing operations. Hydrogen sulfide removal on landfill, digester and producer gases with regenerable chemistries. Odor control for biomass storage facilities including carbon monoxide removal in wood chip storage areas.

    Water treatment for power plants

    The process of electricity generation from fossil fuels such as coal, oil and natural gas is water-intensive. Between 40-50% of all water abstracted and used in developed countries is used in the generation of electricity. Thus, a reliable, abundant and predictable source of raw water supply to a power plant is a critical factor in site selection. Water supplies are required to provide various process waters for the following essential main purposes such as make-up water, cooling water for steam turbine condensers, and auxiliary plant cooling water.

    The primary application of modern water treatment technology is to maintain the integrity and performance of the power plant. Critical plant applications have water purity or conditioning requirements that must be adhered to for safe, reliable and efficient power generation.

    Experience has shown that integration of water technology treatments with power plant design can be very important in reducing operational problems and component failures 

    At power plant worldwide there are increasing limitations on water availability and environmental restrictions on discharges. This is expected to promote measures for water conservation and to have an increasing influence on water treatment decisions. At power plant, the recycling of internal wastewater streams can extend from the recovery of individual high-quality waste streams, which can be reused either directly or after only limited treatment, through to the development of fully integrated water/wastewater treatment systems for zero liquid discharge. However, the application of reuse schemes requires site-specific assessment, as not all waters may be viable options for recovery.

  • Aquatech Enhanced Oil Recovery (EOR)

    In a Steamflood Enhanced Oil Recovery (EOR) process, steam is injected in the well, lowering the viscosity of heavy oil suitable for extraction through the production wells. The fluid from the wells is a mixture of oil, water and gas and goes through a separation system to separate the three. The separated produced water is heavily contaminated with dissolved solids and hydrocarbons. Aquatech’s Steamflood Enhanced Oil Recovery (EOR) Technology offers the integrated solutions for the treatment EOR produced water for boilers, generating a purified product that can be reused for the production and injection of steam. Our turnkey approach to treatment includes coordinating the logistics of wastewater removal off-site and any sludge disposal.
