Prevention of mist formation in amine based carbon capture: field testing using a wet electrostatic precipitator (WESP) and a gas-gas heater (GGH): 13th International Conference on Greenhouse Gas Control Technologies, GHGT 2016. 14 November 2016 through 18 November

This study presents the results of two field tests that aimed at evaluating two countermeasures (WESP and GGH) toavoid acid mist formation. A WESP is shown to be very efficient for the removal of nuclei from the flue gas (100 % efficient) and thus can prevent aerosol formation inside an amine based absorber. This is however only valid in the...

Integrated system for capturing CO2 as feedstock for algae production: 13th International Conference on Greenhouse Gas Control Technologies, GHGT 2016, 14-18 November 2016, Lausanne, Switzerland

In view of its promise as sustainable process for CO2 capture and its potential in the production of feed, food and natural high value products such as omega-3 fatty acids and anti-oxidants such as astaxanthin, large scale algae cultivation is gaining commercial interest. Currently, most systems are based on directly contacting CO2 containing...

Online corrosion monitoring in a postcombustion CO2 capture pilot plant and its relation to solvent degradation and ammonia emissions

Corrosion in amine treating plants is known to cause integrity failures, plant shutdown, costly repairs, and so forth. The use of an amine treatment system for postcombustion CO2 capture brings additional challenges in terms of the flue gas quality, flue gas composition, operating conditions, scale of operation, and so forth. These differences...

Understanding aerosol based emissions in a post combustion CO2 capture process: Parameter testing and mechanisms

Solvent emissions from a Post Combustion CO2 Capture (PCCC) process can lead to environmental hazards and higher operating cost. Aerosol based emissions in the order of grams per Nm3 have been reported from PCCC plants. These emissions are attributed to the presence of particles such as sulphuric acid aerosol droplets in the flue gas. Recently,...

Acid wash scrubbing as a countermeasure for ammonia emissions from a postcombustion CO2 Capture Plant

Amine-based absorption-desorption processes are considered to be the state-of-the-art technology for CO2 capture. However, the typical amines used are susceptible to oxidative and thermal degradation. Ammonia is formed as a result of oxidative solvent degradation. Because of the volatility of ammonia, significant emissions of ammonia can occur....

Future energy-efficient and low-emissions glass melting processes

All over the world, there is an increasing drive to develop new technologies or concepts for industrial glass melting furnaces, with the main aim to increase the energy efficiency, tabilize production and reduce emissions. The application of new process sensors, improved furnace design, intelligent control strategy and waste gas heat recovery...

DECAB: Process development of a phase change absorption process

This work describes the conceptual design of a novel separation process for CO2 removal from flue gas based on precipitating solvents. The process here described (DECAB) is an enhanced CO2 absorption based on the Le Chatelier's principle, which states that reaction equilibrium can be shifted by removing one of the constituents in the reaction. A...

New process concepts for CO2 post-combustion capture process integrated with co-production of hydrogen

This work describes a study in advanced post-combustion based on CO2-capture technologies to be integrated within the Hypogyny concept (electricity generation with co-hydrogen production). Two different Hypogen concepts based on integrating IGCC (Integrated Gasification Combined Cycle) and post-combusting CO2 capture are proposed and...

Reduction of NOx emissions in regenerative fossil fuel fired glass furnaces: A review of literature and experimental studies

The mechanism of nitrogen oxide (NOx) formation in combustion chambers of glass furnaces is briefly described. The most important parameters governing the NOx emissions of glass furnaces are discussed. Elimination or minimisation of conditions that cause the formation of nitrogen oxides in regenerative furnaces have been tested in industrial...

On-line determination of the calorific value of solid fuels

In thermal processes with highly inhomogeneous fuels it is desirable to know real time fuel characteristics. In the case of municipal solid waste combustion (MSWC) it was up till now not possible to determine the calorific value of the waste on-line with a high accuracy. In this paper, a new method is presented where the calorific value is...

CO2 separation with polyolefin membrane contactors and dedicated absorption liquids: Performances and prospects

Evidence continues to mount that the enhanced greenhouse effect is caused by increased emissions of infrared light absorbing components. Carbon dioxide is the largest contributor as a result of the large amounts emitted in power generation processes. This has brought about a sizeable academic and industrial interest in ways to remove carbon...

Selective catalytic reduction of nitrous oxide with hydrocarbons using a SO2 resistant Fe/zeolite catalyst

Removal of nitrous oxide (N2O) from exhausts of chemical plants andcertain combustion facilities is an effective way for substantial reduction of greenhouse gas emissions from anthropogenic sources. ECN has developed a catalyst for catalytic removal of N2O from various exhaust gases using hydrocarbons (propane or methane) as reducing agent. The...

Flue gas treatment with membrane gas absorption

Dutch researchers from the TN0 Institute have developed a technique to carry out gas-liquid contacting operations using hollow fibre membranes in combination with an absorption liquid. The method known as membrane gas absorption, aims to combine the advantages of membrane technology (compactness, flexibility) with absorption processes ...

Evaluation of infrared signature suppression of ships

Reduction of the infrared signature of warships helps to increase their survivability. Two methods to reduce the infrared signature are discussed: the cooling of exhaust gases and the application of low emissivity paint. The infrared signature of a generic frigate has been calculated with and without signature reduction. The signature values are...
