摘要： An apparatus and method are disclosed to detect foam above a liquid sample in a sparge vessel, and disrupt any foam that may exist. The foam sensor includes an optical emitter and optical sensor coupled to a sparge vessel above the level of the liquid sample. Foam is detected if the light beam is attenuated or blocked. The foam disrupter provides thermal energy to raise the temperature of a surface in the sparge vessel to break up the foam, which may condense on the walls of the sparge vessel.

摘要： A method for recovering large volumes of hydrocarbon fuels, particularly methane (CH4), using commercially available reagents which are strongly water-soluble and soluble in liquid CO2 in the presence of liquid CO2 injected into the methane hydrate formation. The reagents which are strongly water-soluble and soluble in liquid CO2 form dilute aqueous acids that significantly increase the rate of conversion of methane hydrate into methane and CO2 hydrate, thereby allowing the natural gas to be released in a form that can then be recovered in large quantities using conventional means. The preferred embodiment uses SO3, HCl or other strongly water soluble gas to cause the methane hydrate ice crystals to melt and form an aqueous solution. The aqueous solution contacts the methane hydrate ice on one side and liquid carbon dioxide on the other side. The system spontaneously adjusts so that the acid solution remains strong enough to melt the methane ice, but not strong enough to prevent the formation of the carbon dioxide ice at the recovery temperature and pressure. The natural gas is liberated from the hydrate and removed by conventional means.

摘要： A catalytic apparatus for exhaust purification, provided in an exhaust path of an internal-combustion engine operable with at least a theoretical air-fuel ratio and a lean air-fuel ratio, is provided with a three-way catalyst (4) having an inner layer (12a) thereof mainly containing rhodium as a noble metal to be activated in an oxygen concentration lowering atmosphere and a surface layer (12b) thereof mainly containing platinum or palladium as a noble metal to be activated in an oxygen concentration increasing atmosphere. In the catalytic apparatus, platinum or palladium in the surface layer is activated in lean operation to perform an HC purifying function effectively. If oxygen is temporarily in short supply during the change from a lean air-fuel ratio of exhaust gas over to a stoichiometric air-fuel ratio, oxygen is supplemented to purify HC by utilizing the O2 storage function of platinum or palladium as the noble metal, whereby the HC purifying rate can be prevented from temporarily suddenly lowering. The catalytic apparatus for exhaust purification can secure satisfactory HC purifying performance even in a lean area without increasing the noble metal loading of the three-way catalyst, so that it can be manufactured at low cost.
