Hi, What is the best way to control the pressure of a chemical reactor in which the feed gas is wholly absorbed and a byproduct gas is formed. 1. Modulating the gas make-up is the best method 2. Relieve valve. 3. ???

What are the main impacts of flashing of the liquid in a vacuum disc filter. I know there will be a lot of steam but will it condense etc.... again since it is a close vessel? filter operates at -70 kPa

My point that I was trying to make was: For 1st hour pump tank is 60 % level. THis is = level SP and the control valve remains at 30 % since SP requirement is achieved. Flow is measured at 0.8 l/s (we have a measurement but it is very erratic because of process). dP across the filter is for...

The control valve controls the level in the pump tank where we pump from. At times the level drops and therefore the control valve cuts back - changing the feed pressure to the filter. - Yes you will probably say that the exit filter pressure will then alos drop and the dP should therefore...

When installing new filters (cartridge) in an existing process with a pump and control valve do you place the filters before or after the control valve. You need to be able to measure the dP across the filters but the problem with the control valve is that it will change your dP measurement.

Hi (Question regarding sodium chlorate plant pump tank transfer) We have a small tank (2 m3) that gets intermittent flow to it. From this tank we pump to the storage tanks. First we have the tank then the pumps (2 pumps pumping in parallel), then a control valve (control the 2m3 tank level by...

Hi. I need to check the capacity of our chillers - since we plan to reinstate a plant that can use up to 50 l/s of chilled water. We allready have a number of other chilled water users. If the chilled water will be heated from 7 to 15 l/s at this new sourch and then send back to the chilled...

What is the best way to calculate heating value of gas to be burnt? do you check composition in GC and then calculate from components - or is there a "calorific meter?"
