In this study, the condensation of methanol and water in unoccupied layers near the coolant tubes of the gas-cooled reactor in mega-methanol plants are investigated. In the Lurgi mega-methanol plants, named conventional configuration (CC), water-cooled reactors are in series with the gas-cooled reactor. These reactors are composed of only two sections, shell and tubes. In the novel configuration (NC), the gas-cooled reactor is modified and consists of three sections including shell, tubes, and mesh. A perforated plate, named mesh, is surrounding each tube by 5 mm from the outer wall of the tube. In the aforementioned space, which has no catalyst, condensation occurs. The coolant temperature in the inlet of the tube of gas-cooled reactor in NC is 20 K smaller than that of CC. The temperature reduction leads to more gas condensation and as a result, the methanol production of NC increases by 20 % compared with CC. A one-dimensional modeling is applied to compare the performances of NC and CC. The results of CC are validated with industrial data.

在这项研究中，研究了巨型甲醇装置中气冷式反应器冷却剂管附近的空层中甲醇和水的冷凝。在名为常规配置（CC）的鲁奇（Lurgi）巨型甲醇工厂中，水冷反应器与气冷反应器串联。这些反应器仅由壳和管两部分组成。在新型配置（NC）中，对气冷反应器进行了修改，并由三个部分组成，包括壳，管和网。一块名为网孔的穿孔板围绕着每个管，与管的外壁相距5毫米。在没有催化剂的上述空间中，发生冷凝。NC中气冷反应堆管入口的冷却液温度比CC小20K。温度降低导致更多的气体凝结，结果，与CC相比，NC的甲醇产量增加了20％。使用一维建模来比较NC和CC的性能。CC的结果已通过工业数据验证。
