Dear colleagues: I have been working with instrumentation in refineries, and the production units I’ve been involved with have always been atmospheric and vacuum distillation units. Recently, the company plans to add hydrogenation units; what are the main differences in terms of instrumentation requirements between hydrogenation units and atmospheric/vacuum distillation units? What skills or knowledge do I need to be competent in instrument work for hydrogenation units?
Why isn’t anyone participating? Do people not have time to think about this issue?
It depends on the hydrogenation process you use; generally, hydrogenation plants operate under high temperature and pressure conditions. Therefore, you need to pay special attention to instruments and valves that can withstand such conditions, as well as the explosion-proof rating of the instruments
All the instruments are functional. Changes in the process mainly involve alterations in temperature, range, pressure, material, explosion-proof rating, etc. For those working in the field of instrumentation, there aren’t really any significant changes in terms of signals Here’s a shortcut: learn the manufacturing process first; a qualified instrument technician must understand it
The hydrogenation unit has high pressure and contains a large amount of hydrogen sulfide! Most instruments have a high pressure rating! Fisher control valves will be used for critical operating conditions, and there should also be 2 reciprocating compressors! The other instruments are the same as at normal pressure!
Our company’s lubricant high-pressure hydrogenation project mainly includes: a 350,000 tons per year furfural refining unit, a 300,000 tons per year lubricant hydrogenation unit, and a hydrogen production unit with a capacity of 10,000 Nm3/h. Where should we start?
The design institute is not involved; work on it by yourself. Pay attention to cutting off and adjusting the high-pressure parts, and use first-tier brands for the instruments
To learn the techniques first, one needs to look at those materials. Could you explain that in more detail? :handshake
Don’t you have the process flow diagrams or process descriptions for your production facilities? PID diagram
