E&Chem Solution will participate in the
42nd International Exhibition on Environmental Technology & Green Energy
(ENVEX 2020) to be held at COEX from June 17 (Wed) to 19 (Fri) to introduce
hydrogen sulfide and siloxane removing adsorbent DeHyS-250.
With the adsorption technology to remove
hydrogen sulfide and siloxane in biogas, E&Chem Solution (CEO Kim
Shin-dong), founded in 2007, is manufacturing and supplying hydrogen sulfide
and siloxane removing adsorbent DeHyS-250 to maximize the usage of biogas to successfully
follow the renewable energy 2030 plan.
It is supplying biogas pretreatment system
to biogas facilities in Korea, and deriving optimal processes to apply
biogas-derived city gas, hydrogen production, and chemical product raw
An official said, "We have secured a
patent for producing adsorbents for pretreatment of biogas from wastes, and we
are currently trying to minimize the cost of pretreatment of biogas by
conducting an environmental assessment for recycling."
Adsorbent DeHyS-250 to remove hydrogen
sulfide and siloxane in biogas are made of porous iron hydroxide (FeOOH or
Fe(OH)3), so it can be used for pre-treatment of anaerobic digestion gas or LFG
and removing highly concentrated sulfuric gas odor. It is an effective
adsorbent for removing hydrogen sulfide, siloxane, ammonia and HF. (Patent
registration no. 10-1616059, adsorbent
for simultaneous removal of hydrogen sulfide and siloxane, acquired performance
The official said, "We are planning to
build a network with technology companies in Korea such as the sludge digester
operating institution in the sewage treatment plant, livestock manure, food
waste, digestive gas treatment plant, and landfill gas treatment plant, and
accelerate the expansion of sales of our products."
Marking its 42nd year this year, ENVEX 2020
has been serving as the business venue every year to help domestic
environmental companies develop domestic and overseas markets. It has attracted
1,000 overseas buyers to provide business matching with the exhibitors in
