Montemayor, do you think that placing a check valve on the discharge line or fabricating an exhaust pipe upstream of the discharge valve of the blowers is possible. I believe that this would elimimnate opening the discharge valve prior to starting because the standby blower could be started even...
There are two blowers on the fired heater at our facility. To switch the blowers the heater must be shut down and the standby blower then started. The standby blower cannot be started with the online blower in operation. Once the discharge valve on the standby blower is opened the heater trips...
At our facility there is a liquid hydrocarbon stream (mainly heavy hydrocarbons) leaves a vessel at -22degrees celsius and a flowrate of 59 cubic metres/hr. It flows through a level valve which maintains the vessel level and into a heat exchanger. Downstream of the level valve there is a phase...
What is the difference between an excess flow check valve and a normal check valve. We have an excess flow check valve in one of our systems and I would like some more information on this valve.
At our facility we vaporize liquid nitrogen from a storage
tank with an ambient air vaporizer. How can this vaporizer fail and allow liquid nitrogen into the gaseous notrogen header. Are there any site to check for vaporizer failures.
