Abstract


The Yanhua butyl rubber device chloromethane dewatering process using activated alumina adsorption methods of removing water dehumidification chloromethane production to meet the basic requirements , but the short cycle desiccant use renewable frequently bring production stability , high operating costs , pollution of the environment , such as a series of questions . This paper presents a new technology to increase glycol pre- existing process before drying tower dehydration on the basis of broad access to technical information and academic exchanges with domestic and foreign experts , to learn the process of natural gas glycol dehydration . By calculating the final selection triglycol as dehydration solvent exchange equipment heat load to the detailed design and new technology in key process parameters such as absorption tower plate number , to absorb the amount of solvent , the desorption tower and cold . Research methods , the main method of combining process simulation and experimental study . Yanhua butyl rubber device applications , it is proved that the process is feasible , the use of new technology, triethylene glycol pre dehydration may be saturated moisture into the alumina prior to the drying tower wet chloride gas from 2000 × 10 -6 dropped of 120 × -6 or so , thus greatly extending the drying cycle of alumina , the production stability has been improved significantly. Also exposed the process is the first commercial application of corrosion of the equipment , entrainment , operating flexibility , some of the problems , to solve the above problem , this paper analyzes and propose new technology gradually improve the rehabilitation measures .
