The spoilage potential of six bacterial species isolated from cooked and peeled tropical shrimps (Brochothrix thermosphacta, Serratia liquefaciens-like, Carnobacterium maltaromaticum, Carnobacterium divergens, Carnobacterium alterfunditum-like and Vagococcus penaei sp. nov.) was evaluated. The bacteria were inoculated into shrimps, packaged in a modified atmosphere and stored for 27 days at 8 °...

Hydrogen sulfide is one of the main waste products petrochemical industry; it produced by catalytic hydrodesulfurization processes (HDS) hydrocarbon feedstocks, and a byproduct from sweetening sour natural gas upgrading heavy oils, bitumen, coals [...]

Many of the oil fields in East Java, Indonesia, are known to contain sulfur amountssufficiently high that crude or associated gases considered sour. The sourgases have be handled accordingly order prevent workers and surroundingcommunities suffering from toxic gas.The flaring system for disposing sour normally applied inIndonesia has been evaluated this study. Flare Stacks typically attempt con...

Protonated organic acid species have been shown to be the primary stimuli responsible for sour taste of organic acids. However, we have observed that sour taste may be modulated when the pH of acid solutions is raised using sodium hydroxide. Objectives were to evaluate the effect of pH adjustment on sour taste of equimolar protonated organic acid solutions and to investigate the potential roles...

The physical adsorption of hydrogen sulfide and carbon dioxide gases on the zigzag (5,0) carbon nanotubes doped with nitrogen was investigated through the application of B3LYP/6-31G* at the level of theory on Gaussian 03 software. A variety of stable and high abundance structures of nitrogen doped carbon nanotubes were considered in order to study the interaction between the mentioned gases in ...

Our industry commonly expends a great deal of energy on determining the concentrations and how to remove CO2 and H2S from sour natural gas in the design of a gas treating and processing facility. Their presence normally drives the size and cost of much of the facility. However, troublesome trace contaminants such as  mercury (Hg),  carbonyl sulfide (COS),  mercaptans (RSH),  and aromatics (...
