The reason is that the control valve doen't know how much flow to recycle. An...
We have been using steam to heat the well fluid and water using plate exchangers. The duty is controlled by throttling the steam pressure at inlet to exchangers. Due to gasket temperature limitations, the maximum steam side operating pressure is limited to slightly above atmospheric. During...
I need to specify the maximum design temperature for flare system. The relieving cases includes an external fire case. During this scenario, the temperature inside the vessel (under fire) increases from 50 oC to start with and goes upto 350 0C,when final heaviers are left in the vessel. I would...
Codes like API-520,521 says about PSV location and inlet line loss for vessels. What if the PSV is provided for derating the piping, when no vessel is there. How the following is taken care in design:
1. If PSV is located far-off from the derating point, is it possible to give the PSV set...
I am looking at the hydrate study for hydrocarbon gas with little hc liquid and water. I would like to know the following:
1. Is hysis good at predicting hydrates? Suggest other softwares giving better results than hysys.
2. Sometimes hysis predicts 'icing takes place first' and says no hydrate...
I am looking for operating experience on sump caisson performance (offshore) designed to limit the oil carryover in water. Has anyone experienced appreciable oil carryover due to wave variations?
Appreciate your input.
