Wide application in petroleum refining industries (fissification, restructuring, isomerization, hydrogen processing), inorganic chemical industries (synthetic ammonia, sulphuric acid, gas conversion) and organic chemical industries ethylene ethylene oxide ethylene oxide, ethylene hydrate ethanol, ethylene deoxystyrene with hydrogen cyclohexane, etc.) simulated acetylene-hydrogen reaction systems, the effect of which is to remove acetylene from the carbon mixture of the top gas phase of the deethane tower. Process equipment: insulation stationary reactor reactor reactor insulation is good, no heat loss and no heat exchange with the outside world. For reversible dermal reaction, the reaction gas temperature is gradually increased by the reaction heat itself released, the entry temperature of the catalyst bed is higher than the catalyst's initial activity temperature, while the export gas temperature is lower than the catalyst's heat tolerance temperature. Thermal stationary reactor is divided into: single-end insulation and multiple-part insulation advantages: 1 is small, fluids and catalysts are effectively exposed, and fixed-bed reactors are more selective when reaction is accompanied by a combination of side reactions. 2 catalyst mechanical losses are low. 3 the structure is simple. Disadvantages: 1 heat spread, when reaction heats are high, even a pipeline reactor may experience flying temperatures (reaction temperature is out of control, sharp rises, exceeding permitted ranges). 2 catalysts cannot be replaced during operation, and catalysts require frequent regenerative reactions that are generally inappropriate and often replaced by fluidized or mobile bed reactors. For acetylene-hydrogen reactors (post-hydrogen) there are two types of fixed-bed reactors commonly used: insulated fixed-bed reactors (sometimes using multiple cascades) and tube-based fixed-bed reactors (temperature reactors). This module is a two-bed insulation stationary bed reactor. Iii. Raw materials and products. Raw materials: carbon-dioxide blended hydrocarbons from the top of the deethane tower, including 86% ethylene, 12% ethylene, 1. 6% acetylene; 15. 8°c hydrogen and coarse hydrogen. Products: carbon dioxide mixed hydrocarbons removed from acetylene at a temperature of -9. 6°c, with acetylene content of less than 5x10-6 reactor reactor acetylene-rich carbon-2 hydrocarbon-free acetylene carbon-2-4; process-mixed hydrocarbons mixed with hydrogen gas after heating into reactor, with acoustic acetylene-hydrogen reaction producing ethylene, with solids usually in a particle size of about 2-15 mm and piled to a certain height (or thickness). The bed layer is static and the fluid reacts through the bed layer. 5. Process process de-ethane tower topware is heated into the acetylene converter (r101a/b) and the ethylene generation method is selected to remove acetylene from the material. The unit has two reactor units that perform switching operations to regenerate catalysts with a mixture of heat vapour and air without compromising continuous operation. The hydrogen step was completed in two stages to increase the selectivity of the response. In the feed of the high-purity hydrogen second-part reactor, the feed of the coarse hydrogen (with co) part of the reactor feed of the reactor is first replaced by heat exchanger (e101), and secondly by low-pressure vapour heating in the preheater e102 to the reaction temperature. Again, it enters the first reactor bed and flows down to the catalyst bed. About 75% of acetylene should be converted in the first bed layer. The emission logistics in one section are cooled in the acetylene converter's intermediate cooler to remove the heat from the reaction, and eventually enters the second reactor bed to react with hydrogen to the remaining acetylene. Catalyst used in this process is a hydrogen-added catalyst using argon metal scattered on aluminium oxide. The first paragraph of the catalyst is operated as a selective catalyst, with conditions set to enhance the reaction of acetylene conversion to ethylene. The second catalyst is a less selective model that minimizes acetylene emissions from reactor logistics. 6. Operating precision 1. Range control to control the heating vapour (ls) volume and the raw material quantity without heat exchangers, respectively, at 30°c. Tic 1001 has an op value of between 0 and 50%, corresponding to the actual opening of the a valve from 100% to 0, at which point the b valve is fully closed, and when op = 0, the a valve is fully open; and, conversely, when op = 100%, the b valve is fully open. E101 e102 tic 1001 b valve a 2. The margin is controlled in this device. Due to the flow size of hydrogen, which affects the temperature of the reactor bed and the export acetylene concentration, it controls the carbon dioxide blended hydrocarbons feed and hydrogen gas feed, i. E., when fic 1001 comes close to the given value (automatic) and fic 1002 drops in order to control the hydrogen input margin; similarly, when two segments of the reactor reach the condition of its input, the fic 1003 is controlled by the margin. 3. Driving point (1) carbon dioxide blended hydrocarbon feed, reactor impulse. Note: valve openings should not be too large when carbon dioxide blended hydrocarbons are initially introduced. (2) hydrogen. The normal flow of carbon-dicarbon blended hydrocarbons is to be built and reactor normal pressure installed before hydrogen gas is introduced. (3) the operational parameters are adjusted to normal 4, stop point (1) to reduce the load input, while adjusting the hydrogen gas feed; to simultaneously turn off the small reactor output valve and maintain temperature, pressure stability (2) to cut the feed to close all feed valves. (3) when all heat-replacement equipment is stopped, the cooling water is stopped when the reactor material is empty. (4) closure of all control valves and all valves on site www. Eastswww. Easts
