大庆石化公司化肥厂于2005年进行的扩建改造工程中,增加了一套分子筛干燥器装置,用于氨合成回路补充气或深冷分离系统原料气的深度脱水。一般配置为:吸附器2台,交替吸附和再生;再生器加热器1台,为分子筛再生提供热源。其中新增的一台再生气加热器(183C)使用了一种新型的平垫密封结构,这种密封结构大胆的在普通平垫密封结构的基础上加以改进,不仅提高了其安全可靠性,而且扩大了平垫密封结构的使用范围,该设备使用状况良好,适用于类似工况条件的使用,值得推广。
Daqing Petrochemical Company fertilizer plant in 2005 to carry out the expansion project, the addition of a molecular sieve dryer device for the ammonia synthesis loop feed gas or cryogenic separation system for the deep dehydration of feed gas. The general configuration is: adsorber 2, alternately adsorption and regeneration; regenerator heater 1, for the regeneration of zeolite to provide heat. Among them, a new regenerative heater (183C) uses a new type of flat pad seal structure, which is boldly improved on the basis of ordinary flat pad seal structure, which not only improves the safety and reliability, But also expand the use of flat pad seal structure, the device is in good condition, suitable for use under similar conditions, it is worth promoting.
