May 20, 2020 · This paper presents the experimental development at demonstration scale of an integrated gasification system fed with wood chips. The unit is based on a fixed-bed, updraft and air-blown gasifier—with a nominal capacity of 5 MWth—equipped with a wet scrubber for syngas clean-up and an integrated chemical and physical wastewater management system. Gasification performance, syngas

Clean Syngas - an overview | ScienceDirect Topics

The upstream syngas process provides clean syngas as the fuel source to the SOFC anode, and it includes a coal gasifier (producing syngas from coal), an air separation unit (providing oxygen for the gasifier), scrubber (removing HCl from syngas), water-gas shift reactor (converting CO and H 2 O to CO 2 and H 2, also converting COS and H 2 O to CO 2 and H 2 S), and a Selexol process (a solvent-based H2S removal process).

Clean Energy: Steam Reformation Technology - Lee Enterprises

The developed unique conversion of carbonaceous materials and a scrubbing/cleaning system produce clean syngas and reduce water and land contamination to protect air, water, and land. The produced syngas has a high hydrogen content syngas – up to 50% by volume, an H 2 /CO ratio over 2, and a high heating value, which is typically higher than syngas produced by competitor technologies.

Gas to Liquids - Small Scale | Lee Enterprises Consulting, Inc.

The syngas is purified and converted in a second, catalytic step to a mixture of hydrocarbons by the Fischer-Tropsch process, or to methanol if that is the desired product. These processes are very well developed for the monetization of natural gas at a large scale, but to date have not been commercial at small scales where one cannot take

Characterization of syngas laminar flames using the Bunsen

conversion of solid fuels into energy, such as gas clean up, sulphur removal, CO 2 capture along with lean premixed combustion in modern gas turbine combustors. These are the key answers for demanding environmental standards. One of the particular concerns, however, is the variability of syngas composition recorded in the gasification industry.

Syngas Production from Coal through Microwave haiqi

Nov 23, 2011 · haiqi gasification is widely applied because of its clean syngas production performance and high chemical reactivity accelerated by the free radicals produced by haiqi. In the present study, the haiqi gasification of four kinds of coal with various conditions of O2/fuel ratio, steam/fuel ratio, and coal particle sizes was performed by using a 2 kW microwave haiqi unit. Nitrogen was used as

Preliminary Screening – Technical and Economic Assessment of

into the use of natural gas as the hydrocarbon source. Nevertheless, the syngas production operation in a gas-to-liquids plant amounts to greater than half of the capital cost of the plant. The choice of technology for syngas production also depends on the scale of the synthesis operation. Syngas production from solid fuels can require an even

Cleaning of gaseous hydrogen chloride in a syngas by spray

brane, hot syngas cleaning, and coal feed pump, are under devel-opment to improve the efficiency of the IGCC power plant [3]. It is estimated that hot syngas cleaning can improve the thermal effi-ciency of IGCC by more than 2% [4]. Coal- or biomass-derived syngas contains contaminant gases such as H 2 S, HCl, NH 3, Hg, As, Se, etc.

Process Simulation and Environmental Aspects of Dimethyl

Jan 19, 2021 · The clean syngas can be sent to the WGS section to convert carbon monoxide into CO 2 and hydrogen, changing H 2 /CO and CO 2 /CO ratios. A reactant is the low-pressure steam. In the carbon capture section, fresh syngas and recycling were mixed to send this mix to the Selexol ® process and carbon dioxide storage changing the CO 2 /CO ratio

Biogas and Syngas Upgrading - ScienceDirect

Jan 01, 2016 · Abstract. Biogas and syngas can be upgraded to produce a variety of products. Biogas (primarily containing methane and CO 2) is generated from waste biomass via anaerobic digestion. Biogas contains a significant amount of impurities (e.g., H 2 S, NH 3 and siloxane) and therefore, a cleaning procedure is generally required prior to applications.

Catalytic Tar Conversion in Two Different Hot Syngas Cleaning

Oct 13, 2021 · Tar in the product gas of biomass gasifiers reduces the efficiency of gasification processes and causes fouling of system components and pipework. Therefore, an efficient tar conversion in the product gas is a key step of effective and reliable syngas production. One of the most promising approaches is the catalytic decomposition of the tar species combined with hot syngas cleaning. The

Syngas Cleanup and Purification - COSTELLO

Jul 12, 2016 · Before any further use can be made of the syngas, these byproducts must be removed and the syngas cleaned up. The first step in the cleanup process is to remove excess ash and carbon particulate. This is followed by removing tars, then ammonia and finally hydrogen chloride and hydrogen sulfide.

Syngas Compositions, Cold Gas and Carbon Conversion

The raw syngas produced from gasifiers needs a cleaning system in case used as fuel for a gas turbine in an IGCC plant. Cleaning syngas means the removal of particulate matter, metallic compounds, and other undesirable pollutants such as sulphur. The cleaning system may be pre-combustion or post-combustion.

China's 'syngas': Bad economics, bad science and an

Apr 24, 2014 · Whence lies the perverse course now being pursued by some Chinese energy companies: to transform coal into gas, at the mine, and then to pipe the gas to coastal cities as a 'clean' fuel. The term 'synthetic natural gas' (SNG or syngas) was invented for this product, and it is as oxymoronic as it is cynical. The origins of SNG are revealing.
