通过对裂解炉、急冷器换热器及真空系统等关键设备及其工艺进行优化改造,探讨出β-蒎烯的最佳裂解操作条件:温度512℃(仪表显示温度)、压力-0.096±0.005 MPa、物料流量60±5 kg/h。在此条件下:月桂烯的选择性≥85%;月桂烯含量≥81%;吨产物裂解耗电(含真空泵用电)≤350 kw。
By optimizing and reforming the key equipment such as cracking furnace, quench exchanger and vacuum system and its process, the best operating condition of β-pinene was explored: the temperature is 512 ℃ (temperature of instrument), the pressure is -0.096 ± 0.005 MPa, material flow 60 ± 5 kg / h. Under these conditions: selectivity of myrcene ≥ 85%; myrcene content ≥ 81%; tons of product cracking power (including vacuum pump electricity) ≤ 350 kw.
