The gases discharged from the sulfur condenser of a Claus process reactor are contacted with an active adsorbent to remove further sulfur and the resulting exhaust gas is afterburned. A desorption gas is passed in closed cycle through the laden adsorbent and is heated, in this cycle, in heat ...
The demonstration of a novel sulfur cycle‐based wastewater treatment process: Sulfate reduction, autotrophic denitrification, and nitrification integrated... Saline water supply has been successfully practiced for toilet flushing in Hong Kong since 1950s, which saves 22% of freshwater in Hong Kong. In...
Drawing from the fractionation column a stream of high-sulfur hydrocarbons, cracked naphtha and light cycle oil fraction; introducing the high-sulfur hydro... A process for reducing sulfur compounds in naphtha to produce gasoline of ultra-low sulfur content, i.e., 10–30 ppm of sulfur, from ...
l. A method for hydrogenating and desulfurizing a cycle oil from the cracking of petroleum stocks, said cycle oil boiling above 415 F. and containing highly aromatic hydrocarbons and from 0.5 to 3.0 wt. percent sulfur which comprises contacting the cycle oil in the form of a slurry for ...
The process may be operated using a pressure swing, temperature swing, partial pressure swing, purge displacement, or a combination thereof between the sorption and desorption portions of the cycle, preferably in a rapid cycle operation. 展开 ...
. Gray cast iron graphite has a flake structure that is significantly responsible for its high machinability [26]. In addition to the effects of the graphite structure on the machinability of gray cast iron, the metal contains other elements that lead to better machinability, such as sulfur and...
et al. Investigation on thiosulfate-involved organics and nitrogen removal by a sulfur cycle-based biological wastewater treatment process. Water Res 69, 295–306 (2015). 11. Wang, J. et al. A novel sulfate reduction, autotrophic denitrification, nitrification integrated (SANI) process for saline...
of the feedstock after which the conversion of the gaseous product (synthesis gas) to hydrocarbon derivative is achieved. The Fischer-Tropsch process has received intermittent attention as a source of low-sulfur diesel fuel and to address the diminishing supply of crude oil–derived hydrocarbon ...
