RHT has developed a unique configuration to provide highly selective processes for Vinylacetylenes, MAPD , Butadiene  and higher dio-olefin selective hydrogenation at low cost. This uses fixed bed conventional technology in a two phase with a unique reactor configuration, which provides longer catalyst life with conventional catalyst, better selectivity and lower Opex and Capex. Any extra equipment is paid off in 3 to 15 months compared to other technologies.
