31. They must be correctly orientated or they do not allow the liquid to flow past the gas stream . 32. However, they will tend to plug or corrode if particle concentration of the exhaust gas stream is high. 33. The process of taking hydrogen sulphide out of a gas stream is called " sweetening " the gas. 34. While the individual compartment is out of place, the gas stream is diverted from the compartment s area. 35. Note also that the mixed gas stream will also contain some inert gases such as nitrogen and carbon dioxide. 36. As with other types of venturis, a means of separating entrained liquid from the gas stream must be installed. 37. After picking up heat from the blade / vane, the cooling air is dumped into the main gas stream . 38. It is usual for some entrained compressor oil to carry over into the compressed-gas stream downstream of the compressor. 39. Three-way catalytic converters can store oxygen from the exhaust gas stream , usually when the air fuel ratio goes lean. 40. The steam is then superheated in tube bundles placed in the solids circulating stream and the flue gas stream .
