HP Reliability: Avoid unnecessary developments

Bloch, Heinz P., Hydrocarbon Processing Staff

Innovative thinking is appropriate in the hydrocarbon processing industry, and tremendous forward movement has occurred over the past 30 years. Innovation is to be commended, unless we invent or disco..

HP Reliability: How do you size expansion chambers (assuming it is needed)

Bloch, Heinz P., Hydrocarbon Processing Staff

Expansion chambers (Fig. 1) are designed to restrict pressure increase in closed volumes. From basic physics, we, of course, know that the pressure in a closed volume increases as temperature goes up...

HP Reliability: Consider ‘water washing’ for steam turbines

Bloch, Heinz P., Hydrocarbon Processing Staff; Dowson, P., Elliott Group

Occasions may arise when deposits form on the internal parts of steam turbines. The accumulation of these deposits may be indicated by a gradual increase in stage pressures over time with no evidence ..
