I have existing boiler (4MMBtu/hr), and the condensate return from the Process side is going directly to Boiler Feed Water Tank. Plant is not in use since last couple of years and client is planning to start the plant. It is a small boiler so it doesnt have deaerator.
The concern is from the...
I need to size the Emergency vent based on API 2000, however, the properties of the material is not known. It is non-flammable fluid but the properties of the material is not known.
Can anyone suggest me the reference page where API-2000 / NFPA 30 states that one can assume Hexane and use the...
My Steam requirement varies from 1500 lb/hr to 13500 lb/hr. Based on 13500 lb/hr flow I am considing 6" steam header and 4" condensate header.
For 6" line and 1500 lb/hr flow I am getting velocity of 7 ft/sec which is lower side for the steam line sizing criteria.
I was just wondring if I can...
I have steam/water Shell and Tube exchanger and my flowrate for steam is 6500 lb/hr and water is 55,000 lb/hr.
I would like to have your inputs for the desired location for Water and Steam. As water flowrate is higher, I thought of placing the water at shell side.
I have an application to "Top offload" viscous chemical (1600cP) from the Rail car and the pump is located at the Grade.
The elvation of the bottom of the rail car and highest point of the loading arm is 20ft. Is it possible to have gear Pump which unload the material without pressurizing the...
Hi,
I am performing exchanger design and found that my LMTD is zero as my heating and cooling flow are same.
Does it mean that the design is not correct?
Thanks!
For one of the storage tank (non flammable material- Flash pt >200F) has the capacity of 29000 Gallon (100,000 Liter). I have sized the normal vent for breathe in/out, which is atmospheric vent with bird screen.
I would like to know if i have to design the Emergency vent for this tank for fire...
