An analog output signal generated by SIEMENS DCS needs to transfer a package unit PLC (also by SIEMENS) through an analog input channel as depicted below. Question is, will work or an isolator will be need?
Dear KeviNZ
Thank you.
Right, this is a geothermal plant. As I explained in past posts, our very first design was based on flashing on a control valve. But we did not sure about either flashing on a butterfly valve or even huge erosion occurring in that.
Flashing in butterfly I think little...
Dear Rspain
Condensate has been generated from or better to say separated from two phase fluid of Geothermal well and It is saturated, yes.
Downstream of separator there is set of ejectors that designed to consume steam as motive fluid in specific process conditions.
You right, at very primitive...
OK. first, in separator there is a vertical pipe connected to nozzle B.
Maybe it was just a misunderstanding. Downstream required steam is about 3% and the rest will be vented.
Despite all of these details, Do you have any major comment on designed arrangement of valve and RO? Have you ever seen...
Dear Latexman
You right. Our 3% is calculated with a margin to being ensure about performance. But the main point is as you said, using control valve as a flash valve. Actually in upstream of restriction orifice, there is butterfly type control valve that regulates a level of some vessels.
In...
We are now working on designing a Geothermal power plant. In a specific point condensate with 10 bar in 200 ton/h flow rate should be flashed to recover extra steam of 6 bar for using as motive steam in ejectors.
Based on our calculation, in such pressure changing, we can obtain about 3% (of...
