摘要:
A process of integrated system formed by coupling of fixed bed, jetting floating bed, and separating unit, aimed to provide a new process and equipment of higher efficiency, which integrates multi-type reactors and separation is provided. Reaction materials undergo preliminary reaction in fixed bed reactor and intensified reaction in jetting floating bed reactor, and then separation in the subsequent separation system. Unreacted materials will be returned to the raw material intermediate storage tank for mixing with fresh materials, as raw materials for continued reaction. During this process, materials first pass the fixed bed reactor once to achieve certain conversion rate, and then enter the jetting floating bed reactor for intensified reaction. When the product reaches required concentration, the materials will enter subsequent separation equipment for separation.

A process of producing degassed liquid sulfur within a horizontal sulfur condenser may include condensing a portion of a Claus process gas introduced into a condenser tube to produce liquid sulfur; creating first and second chambers above a liquid sulfur reservoir with a baffle; passing the liquid sulfur and the Claus process gas into the first chamber; forcing the Claus process gas from the liquid reservoir within the first chamber to the second chamber; causing a chemical reaction between dissolved hydrogen sulfide in the liquid sulfur and sulfur dioxide from the Claus process gas on a catalyst to produce elemental sulfur and reducing the dissolved H2S content of the remaining sulfur; converting hydrogen sulfide by a Claus reaction; decomposing polysulfanes to hydrogen sulfide and sulfur, freeing elemental sulfur from hydrogen sulfide; forcing the Claus process bubbles from the liquid reservoir into the second chamber above the liquid reservoir.

The present invention provides a process for preparing ethylene and/or propylene, wherein an oxygenate feedstock is contacted with a molecular sieve-comprising catalyst at a temperature in the range of from 350 to 500° C. to obtain a reactor effluent comprising ethylene and/or propylene and the oxygenate feedstock is contacted with the catalyst in a riser reactor having a reactor wall defining a flow trajectory towards a downstream outlet for reactor effluent, wherein at least oxygenate feedstock and catalyst are provided at one or more upstream inlets of the riser reactor and wherein a water quench medium is admitted to the riser reactor at one or more of locations along the length of the flow trajectory through a plurality of inlets distributed along the periphery of the reactor wall. The invention further provides a reaction system suitable for preparing ethylene and propylene.

An integrated process simultaneously removes the diluent and reduces the TAN, resulting in cost savings from the diluent recovery and increasing the value of the produced heavy crude stream by removing the acids and other contaminants, while reducing the overall energy requirements when compared to performing the two processes separately.

A moving bed gasification/thermal treatment reactor includes a geometry in which moving bed reactor particles serve as both a moving bed filter and a heat carrier to provide thermal energy for thermal treatment reactions, such that the moving bed filter and the heat carrier are one and the same to remove solid particulates or droplets generated by thermal treatment processes or injected into the moving bed filter from other sources.
摘要:
A method and device for limiting the degassing of tritiated waste issued from the nuclear industry are provided. The method reduces an amount of generated tritiated hydrogen (T2 or HT) and/or tritiated water (HTO or T2O) including at least one piece of tritiated waste from the nuclear industry. The method includes placing the package in contact with a mixture including manganese dioxide (MnO2) combined with a component that includes silver; and placing the package in contact with a molecular sieve.

The invention reduces the potential for catalyst fluidization in a reduction vessel of a continuous catalyst regeneration system. The gas exit area from the catalyst reduction zone is increased by ventilating the cylindrical baffle of the upper reduction zone. This provides an increased exit cross-sectional area for the upper reduction gas to escape and reduce the overall exit velocity of the combined upper and lower reduction gases and reduces the potential for catalyst fluidization.
