Sentence translation
Thread Content
The full sentence is as follows: The flow from the final stage of the compressor proceeds to the feed preheat section of the primary reformer, 101-B, under the control of the flow ratio recorder controller, FRRCa-2, which determines the flow rate in proportion to the reforming steam rate by setting the value of FRC-1. In essence, it means that the natural gas flowing into this reactor is controlled by a steam-to-carbon ratio regulator; however, the specific part mentioned here is difficult to translate accurately, so I hope everyone can help with that.

I’m not quite sure how to translate “index,” so for now I’ll use “index” as the translation. The sentence structure of the bolded part is fairly clear; “which sets the rate in ratio to the reforming steam rate” constitutes the main part of the sentence and functions as a clause that modifies FRRCa-2. “By setting the index of FRC-1” explains the specific way in which this function is achieved. The material coming from the last stage of the compressor enters the feed preheating section of reactor 101-B under the control of the flow ratio recording controller (FRRCa-2); this controller sets the flow rate proportionally to the amount of conversion steam by adjusting the exponent of FRC-1.
The material coming from the final stage of the compressor enters the feed preheating section of the first conversion furnace (101-B) under controlled conditions; its flow rate is regulated by a proportional register controller (FRRCa-2), which sets this flow rate based on the ratio of the conversion steam flow rate to the value provided by FRC-1
Reform should mean restructuring, right? Can “index” be translated as pointer or indicator (since it seems that FRC-1 is also a controller)? Translation: The FRRC-2 controller sets the feed flow rate to be proportional to the reforming steam flow rate by adjusting the pointer (or indicator) of FRC-1.
In summary: The material coming from the last stage of the compressor enters the feed preheating section of converter (101-B) under the control of the flow ratio recording controller (FRRCa-2); this controller sets the material flow rate proportionally based on the flow rate of the conversion steam by adjusting the pointer of FRC-1.
