Hi Georgeverghese, the tubes were light expanded 3-5% with seal weld. I guess the clearance is still exist more or less. So, I took it conservative with 0.15 mm clearance in the calculation.
Hi,
I am finding the calculation method for the maximum leak rate of a gas/liquid mixture through clearance between tube and tubesheet of an air-finned cooler. The fluid contains 79% H2 gas, 19% liquid hydrocarbon, and 2% liquid water at 181 barg and 168 degC. There is a 0.15 mm clearance...
I am reviewing the process ability of new crude with high Nitrogen in High Vaccumm Waxy to Hydrocracker Unit. At this stage, I assumed that total Nitrogen (about 3000 ppm) is totally converted into NH3 and NH4HS would be about 3.0x3000 ppm or 1%wt. However, this value seems to be very low in...
