Can you suggest me how do i decide the set point for a pressure switch for auto changeover of stand-by pump?
The system consists of two condensate pumps, one working and one stand-by, for a condenser, with a pressure switch at the discharge for auto-changeover.
Below is the flow-head...
We are planning to use colored glycol water and install an observation tank in the condensate line.
But we need a continuous auto monitoring, with feedback to three-way valve to lead the condensate to bilge well in-case of contamination.
betrueblood,
I looked on the web and found that the conductivity of Fresh water-Ethylene glycol solution is less than 0.5 ppm. So not sure, whether a conductivity sensor would give very accurate results.

Monitoring the level in the GW expansion tank is definitely a way. But there are other units in the system as well.
For eg: LNG vaporizer utilizing the GW closed circuit, and SW-GW heater as well. The level could be due to leakage anywhere else.
The idea is to continuously monitor the...
Is there a method or system for continuous detection of water-ethylene glycol solution leakage into the condensate stream of a GW/Steam heat exchanger?
Would a conductivity sensor be suitable for the above purpose?
For a Steam system onboard a ship, we need to have an atmospheric dump condenser to dump any excess steam during periods of low demand. Is there any guideline on the sizing of the dump condenser? Should it be equal to the Boiler steam generation capacity?
Thank you LittleInch and TugboatEng

For a LNGC to FSRU conversion project, we are installing Feed pumps in each LNG Cargo Tank, 4 in total.
The new Feed pump will feed LNG to the regasification skid via a new Feed Main.
For flexibility, it is required to have the provision of feeding the regas skid via the existing Cargo pumps...
