Our company has a process unit, and during the translation process I encountered the following issues (see the red-marked parts in the original text). I would appreciate it if experts could offer guidance to help resolve these problems. Thank you in advance! Translation of the changes in temperature requirements after altering the feed in the two tables (that is, the second row in each table; experts’ assistance is requested): 7.1.3 Reactor Heating. The following limits are provided as guidelines for reactor heating: To avoid high thermal stresses, the maximum temperature difference between any two surface points is determined by the temperature gradient between those two points. For reactors, this maximum gradient is 28°C (50°F) over a characteristic length equal to 2.5 R*T, where R is the reactor radius and T is the wall thickness. Calculating the maximum temperature difference between any two surface points results in numerous temperature differences that need to be monitored. Experience has shown that the following limits generally allow reactors to be heated without experiencing excessive thermal stresses. Process Fluid Limits, Reactor Surface Temperature MPT (MPT refers to the minimum pressure increase temperature), Feed Temperature Change

This does not seem to be the original English version of a foreign company’s text; if it is your company’s translation from Chinese to English, it would be better to provide the relevant Chinese information. Especially the last sentence, “Experience has shown that the following limits will usually allow the reactors to be heated without excessive thermal stress,” has a tone and way of thinking that don’t quite conform to natural English expression. Personally, I think that regarding the wording, structure, format, and way in which the sentences are expressed, this text should draw the attention of the original poster; it seems to be unfinished. If that is indeed the case, and if this text is to be turned into an English document for public release, it is recommended that the original poster refine their translation further. Please forgive any imperfections!
Reply to 3# tigerli358_Can: Thank you for the reply from above; thanks for your advice and reminders. This is the documentation on the CLG residue oil processing technology that our company has newly introduced. We are currently working on translating it, and due to my limited English skills, I would like to seek advice from experienced teachers and colleagues.
Building on the existing single-stage one-pass (SSOT), single-stage recycle (SSREC), and two-stage (TSR) hydrocracking process technologies, Chevrn and ABB Lummus Golal have continued to improve both the processes and the performance of the catalysts. Chevrn successfully entered the Chinese market in the 1980s and is likely world-class in the processing of residue and heavy oil. The introduction of the Qilu Petrochemical plants is a good example. There are several experts on this chemical engineering English forum; you can communicate with them!
