This work evaluates the performance of a plant to produce 2000 tonnes per day of methanol using CH₄ tri-reforming for syngas production. A sensitivity analysis is performed on the feed composition of a tri-reformer operating at 3000 kPa and 1000 °C to maximize its CO₂ conversion and syngas stoichiometric number (SN). The optimum feed composition is determined as CO₂: 0.20, H₂O: 0.35, and O₂: 0.48 for each mole of CH₄, resulting in a CO₂ conversion of 50% and an SN of 1.57. Oxygen is injected at four locations along the length of the tri-reformer to manage the temperature profile of the reactor. A pressure swing adsorption unit with four columns and eight steps recovers hydrogen from unreacted gases to increase the syngas SN to 2.04, which is suitable for methanol synthesis. The net present value of the plant is $161 million for a 15-year economic life based on a methanol sale price of $390 per tonne. Monte-Carlo analysis of the plant economics indicates that there is an 84% chance for the plant to be viable considering the simultaneous uncertainties in influential economic parameters. The plant has net CO₂ emissions of 0.91 kg CO₂/kg methanol, which is 50% less than the conventional methanol plants based on the steam reforming of methane and 35% lower than other methanol plants based on CH₄ tri-reforming.

这项工作评估了使用CH ₄三次重整生产合成气每天生产2000吨甲醇的工厂的性能。对在3000 kPa和1000°C下运行的三重整炉进料组成进行了灵敏度分析，以最大程度地提高其CO ₂转化率和合成气化学计量数（SN）。对于每摩尔CH ₄，最佳进料组成确定为CO ₂：0.20，H ₂ O：0.35和O ₂：0.48 ，得到CO ₂转换率为50％，SN为1.57。沿着三重整器的长度在四个位置注入氧气，以控制反应器的温度分布。具有四个塔和八个步骤的变压吸附单元可从未反应的气体中回收氢气，从而将合成气SN提高至2.04，适用于甲醇合成。根据每吨390美元的甲醇销售价格，该厂在15年的经济寿命中的净现值为1.61亿美元。蒙特卡洛对工厂经济的分析表明，考虑到影响经济参数的同时不确定性，工厂有84％的可能性能够生存。该工厂的CO ₂净排放量为0.91 kg CO ₂/ kg甲醇，比基于甲烷蒸汽重整的常规甲醇装置低50％，比基于CH ₄三重整的其他甲醇装置低35％。
