A look at the role that liquid ring vacuum pumps and compressors play in the ethanol and biodiesel production process.

In the oil and gas industry, electric submersible pump (ESP) systems are probably best known as an effective artificial lift method of pumping production fluids to the surface. ESPs are especially effective in wells with low bottomhole pressure, low gas/oil ratio, low bubblepoint, high water cut or low API gravity fluids.

Propane refrigeration systems are often required in the natural gas processing industry to provide the required chilling in condensing heavy components for a rich gas. This study explains a simple correlation to estimate compressor power and condenser duty per refrigeration duty in three-stage propane refrigerant systems - important parameters to consider when designing any refrigeration system.

A note from Robert X. Perez:
Welcome to this installment of Compressor University!
Most high-speed centrifugal compressors rely on fluid film bearings-such as tilting pad journal (TPJ) bearings and equalized (Kingsbury style) thrust bearings-for rotor support and positioning. A compressor's rotor position must be maintained within a few thousandths of an inch to operate efficiently and reliably. A bearing failure will not only mean a compressor shutdown; it could also result in secondary or peripheral damage to costly internal parts. Early detection of a bearing failure may only result in an outage lasting a few days, but an undetected failure, causing major internal damage, can force an outage for weeks or months.

A major concern of U.S. petroleum refineries and chemical process plants is regulatory compliance. Federal, state, special regulatory district and consent decree mandates require compliance of all regulations with the 1990 Clean Air Act (CAA). Petroleum refineries were an early priority target for the EPA. It is likely that chemical process plants will become the next focus of EPA attention.
