Thread Content
The Chemical Engineering Theory section is launching the \"One Question per Day\" campaign starting today, aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequent campaigns will cover topics such as \"Principles of Chemical Engineering,\" \"Mass Transfer and Separation,\" \"Thermodynamics in Chemical Engineering,\" and \"Chemical Process Engineering.\" We hope you will give it your active support~~~ Answers to the questions in the \"One Question per Day\" campaign can be viewed directly by replying to the post, and the topic will be closed after 1 day! ! To encourage everyone’s continued participation this year! You get 3 wealth points for participating, and an additional 4 wealth points for answering correctly~~~ Short answer question: What type of equipment cannot be cleaned using hydrochloric acid?
Hydrochloric acid can be used to clean copper equipment, but it is necessary to add acid cleaning corrosion inhibitors, and the concentration of hydrochloric acid as well as the processing time must be carefully controlled.
