摘要:
The invention relates to a method for producing high-purity 1,2-dichloroethane from dissolved chlorine and dissolved ethylene which are brought into contact with each other using a circulating liquid reaction medium which essentially consists of 1,2-dichloroethane and a catalyst and passes through at least one vertical reaction loop. The two limbs of the loop are connected to a gas-phase stripping container which is arranged at the top and from which the reaction product is outwardly transferred either in a gaseous or liquid form or both in a gaseous form and in a liquid form. The addition points for the addition of chlorine and dissolved ethylene are arranged in the limb of the loop in which the liquid rises. The addition point for dissolved chlorine is always arranged downstream of the ethylene addition point. At least one addition point for liquid 1,2-dichloroethane follows each chlorine addition point, and the addition of the liquid 1,2-dichloroethane is carried out under kinetic energy which is high enough to enable a vigorous mixture of 1,2-dichloroethane, dissolved chlorine and ethylene to be carried out. Preferably, the liquid 1,2-dichloroethane is added by means of at least one jet mixer.
摘要:
An apparatus (10) and method for combining multiple materials into a stream. The multiple materials may include both a major material and one or more minor materials. The minor materials are added using inlet tubes (141) . The major and minor materials are added at transient or steady state flow rates, depending upon a command from a control signal . The apparatus and method utilize a control system which does not have flow control valves, flow control feedback loops or a dynamic mix tank. The actual flow rates track the commanded flow rates, but deviate by an error. The claimed arrangement provides a time-based error believed to be unobtainable in the prior art.

A fuel reforming apparatus (20) for reforming hydrocarbon-based fuel into hydrogen-rich fuel gas comprises a reforming reactor (30) for reforming the hydrocarbon-based fuel into a reformed gas containing hydrogen and carbon monoxide; a water gas shift reactor (34) for converting steam and carbon monoxide into hydrogen and carbon dioxide; a connector (32) for connecting the reforming reactor (30) and the water gas shift reactor (34) to allow the reformed gas from the reforming reactor (30) to be fed to the water gas shift reactor (32), the connector including a reformed gas permeable member disposed proximate to the reforming reactor (30); and liquid water feeding means (31) for feeding liquid water to the reformed gas permeable member. The reformed gas permeable member has a plurality of gaps or capillaries capable of passing the reformed gas from the reforming reactor (30).

The invention relates to a device for the molecular integration or disintegration of solid, liquid and/or gaseous flowing, entrained and/or countercurrent components by means of cavitation in order to modify, build or disintegrate molecular compounds. The invention allows to obtain stable mixtures from immiscible or difficult-to-mix components or to separate such mixtures. The supercavitation molecular reactor allows to build up or disintegrate or modify, with low expenditure in terms of energy, even complex compounds that so far have not been accessible to modification and/or production or only by very extensive multiple processes and a large amount of technical complexity.

摘要:
An object of this invention is to provide an exhaust gas purification device with which a decrease in reduction (denitrification) efficiency can be reduced. An exhaust gas purification device of this invention for a ship 1 includes: a reducing agent injector 61 of a reducing agent supply device supplying a reducing agent to an exhaust gas passing through an exhaust pipe of an engine 21 to be mounted in the ship; an exhaust mixer 62 mixing the exhaust gas and the reducing agent in a location downstream of the reducing agent injector 61 in an exhaust gas traveling direction; and selective catalytic reduction devices 34, 35 facilitating reduction of NOx in the exhaust gas of the engine 21 in a location downstream of the exhaust mixer 62 in the exhaust gas traveling direction. Multiple reducing agent injectors 61 are provided, and respectively have injection ports arranged at equal intervals along a circumferential direction of the exhaust pipe.

"IMPROVEMENT ON FACILITY FOR REMOVAL OF MATERIALS AND / OR POLLUTING SUBSTANCES CONTAINED IN WATERCOURSES", applied to facility comprising : the implementation of a sandbox arranged at the bottom and in a stretch of the watercourse, followed by a floating garbage fence arranged substantially transversely to the watercourse; whereas downstream and at a certain distance from this garbage fence is provided a suspended and transverse metallic structure to the watercourse, in which curtains for selective injection and automatically set in motion are mounted, arranged spaced and interspersed by homogenization diffusers, these curtains are responsible for the injection of coagulants; by the injection of polymers into the watercourse to be treated, and ahead there is a phase for release of microbubbles of air, causing a flotation of these aggregate particles; allowing that from this flotation stretch arises, along the watercourse, a superficial agglomeration of the floated material, and the conduction by flexible and longitudinal barriers formed by synthetic membranes of this floated material to a transverse alignment of dredging modules, that extend through the entire watercourse's width promoting the concentration of floated material and its removal. This improvement consisting of all equipment (3, 4,7) originally installed transversally the watercourse, which are subject to partial or total removal from this transverse condition, allowing the clearance of part and/or entire bed of the watercourse.
