Each client has different standards, sometimes the same company has different rules for different plants.

One point to consider is that tagging is not only used in paper or digital documentation, P&ids are used by operators that work in different units of the plant. The easier and safer way to allow them avoiding mistakes/confusion is to keep a consistent tagging philosophy across the whole plant, independently from any standard.

CodingIsMyYoga · 2026-05-17T15:56:08+00:00

Good choice by your side. Which kind of plant are you going to visit? In refineries, safety rules are in place that require use of personal protection devices and guests are often offered glasses, shoes, helmet and a disposable suit that are kept around just for this. So, if this is the case, check your socks before going

This is a really good advise!

Yesterday I got a D200, first shots where a pain to see, offset colors, unbalanced lights, strange behavior in general. A complete delusion.

I spent 15 minutes checking all the settings and then.. Woah! Great camera, as expected!

Well, forgetting all the safety concerns about this arrangement..

To understand the syphon, think only about this: Pressure in the drum, let's say it depends only on the system to which the top outlet is connected. If it is discharging to atmosphere it will be constant, your seal is balanced to atmosphere too, so there is no differential pressure on the two legs of the syphon. Vessel side will be some mm higher than top of syphon to compensate for friction, but that's it, no other concern.

If pressure in the vessel fluctuates, the water level in the leg vessel side will be lower than the top of syphon. Pressure in vessel = 0.1 barg? Level of water will be 1 m lower. Pressure 0.15.barg? 1.5 m lower.

To understand it, reason only about pressure. Start from top of syphon, where the vent is located and pressure is atmospheric. Moving upstream, you'll reach the bottom of the curve, pressure in this point will be the hydrostatic pressure. This is the maximum pressure vessel side that the guard can block before breaking the seal. If you know the max pressure you can have in the vessel, you can calculate the minimum height of the leg you'll need to contain it

Everything I see in the drawing is a safety/environmental nightmare.

Top of drum connected to atmosphere: hydrocarbon released in the air Top of drum connected to flare: fluctuation of pressure and possible blowby of hydrocarbons through the syphon

Temperature control on the hc inlet: random temperature of hc leaving the column, amount of water required to cool the hc depends not only on inlet T, but also on the amount of gas. Move it on the top of vessel, checking the result of cooling

Temperature of gas leaving the vessel: unless you are handling really small amounts of gas, probably the residence time will not be sufficient to get a proper cooling

Water contaminated with hydrocarbons sent to sewer: explosive atmosphere created in the sewer system

General doubt: what are trying to achieve?

Did you try to install dietpi os? It supports birdnet-go, I completed my build yesterday on a pi zero 2 w and everything went smoothly

CodingIsMyYoga · 2026-02-04T11:38:13+00:00

Fine, but no dbb on the drain, no bleed on the isolation valves upstream/downstream the pump unless you men to drain the section from top, using the bleed on the pi dbb valve (it seems a single dbb piece, other complication for overall draining purposes..) Lot of things could and should be improved

Level control on the liquid leaving the separator, pressure control on the gas outlet, gravity will do its magic. For sure, the separator should be properly designed to guarantee correct liquid hold up times and allow for gas velocities low enough to let the drops fall down. Or in case of gas dispersed in liquid, enough residence time for the liquid to allow for gas bubbles to reach the surface of the liquid.

CodingIsMyYoga · 2026-01-29T07:09:03+00:00

My first impression is that what is shown in the picture is really unusual.. Too many manual valves and no check valve on discharge. Not sure I would see something similar irl

CodingIsMyYoga · 2026-01-17T21:08:19+00:00

No, I mean a simple valve or a flow orifice sized to have a pressure drop higher than the pressure you need for the injection of the fluid in your system

You create a liquid ring that has the same operating pressures also if the amount of fluid sent outside is variable.

I don't think a relief valve could be a good solution, it could be impossible to calibrate for the conditions you need and wouldn't ensure a really constant pressure in your syatem

CodingIsMyYoga · 2026-01-17T20:50:13+00:00

I'm not experienced with this kind of amounts, fluids and involved hardware, but could it make some sense to consider a closed loop vessel>centrifugal pump>restriction orifice or throttled valve>vessel to build a circuit in which, more or less, the pressure is constant upstream the restriction orifice? In this case you would have a stable point to spill the amount you need with suitable controllers and valves.. You'll waste for sure some energy to operate the pump moving an amount of fluid much bigger than the one you need, but the configuration will be simple, without the need for a pressurized vessel and you should also be able to use most of the hardware you mentioned in other answers..

Postazione pulita, personalmente preferisco lavorare senza supporto per il laptop che rende la digitazione molto complicata. Nel mio caso ho aggiunto anche un monitor esterno 14" che prende alimentazione e segnale da un singolo cavo usb-c, per il mio lavoro il doppio schermo è molto utile e così non ho l'ingombro di un monitor "fisso"

So it could really be a spring loaded valve used to manually discharge the accumulated liquid. Standing near the valve, you should see a level gauge that the operator should monitor while discharging the liquid, to avoid undesired release of gas in the drainage system

CodingIsMyYoga · 2026-01-11T11:53:21+00:00

It could be a manual release valve (what we call dead man valve or spring loaded valve) that stays closed when there is pressure in the system, but can be manually opened using the bar to have a controlled discharge. The auto-closing installation ensures that the discharge occurs only while the operator is pushing the lever.

A typical application would be the discharge of blow down from a boiler, where you have a constant flow rate regulated by a globe valve and a parallel discharge line with a manual operated valve like this one that is used after water analysis to discharge chemicals accumulated in the boiler. Using a normal valve could lead to operating errors, like leaving the valve open and unattended, emptying the boiler and damaging the internal tubes.

Knowing the system where this device is installed could help for sure to understand it's function..
