You can attack the line pressure issue by setting a compressor and reducing the head pressure that the well has to flow against. Now the 200 mcfd rate that was not keeping the well unloaded at 50-60 psi line pressure with 2-3/8” tubing can keep it unloaded and keep fluids entrained in the gas at 10 psi suction pressure of the compressor.

The main valve is closed and the pilot valve is open by spring force at start up. Steam flows through the pilot valve to the diaphragm chamber and out through the control orifice. As flow through the pilot valve becomes more than the flow through the orifice, pressure increases on the main diaphragm and the main valve opens. As steam flows through the main valve, the downstream pressure increases and feeds back through the pressure sensing line to the lower side of the pilot diaphragm. As spring force and force below the pilot diaphragm balance, the pilot valve throttles. The main diaphragm pressure positions the main valve to release enough steam to maintain delivery pressure. Adjusting the pilot diaphragm spring varies the downstream pressure.

Balance of Plant systems are critical to all #power plants and maintaining them can be the difference of producing #clean and #reliable power. Join industry experts from EPRI and companies globally to discuss how these systems operate and the #technology being developed and implemented to improve all aspects around BOP.

Here are some reasons why dry gas seals (DGS) on centrifugal compressors fail 1. Contamination by process gas: The gap between the primary ring and the mating ring is about 3 microns, so the gas must be filtered to maintain the gap without damaging the surfaces. 2. Lube oil contamination: Liquids forming between the seal faces or oil reaching the faces while the compressor is not rotating may stick together. 3. No lift: Lifting the mating rings requires minimum gas pressure between the faces and minimum shaft speed. 4. Forced contact: Two faces have been forced to contact each other during normal or transient conditions, such as startup or shutdown.y

In our webinar tomorrow, we'll review the most popular types of heat exchangers, including gasketed plate heat exchangers, brazed plates, and shell & tube. We'll also explain why fouling is a major performance issue and what maintenance protocols are required to ensure proper flow and heat transfer. Register today: https://bit.ly/3w5pJQQ Jacob Wolfe

🔸 A shell-and-tube heat exchanger is a class of heat exchanger designs. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. ...and you knew how the heat exchanger works ❓

For cryogenic service I agre with unclesyd: 304 has better properties than 316, but the difference is so small, that I think that the main reason which makes 304 to be used for cryogenic service is the money. For cryogenic service (typical LNG or LN2) corrosion is not a problem (usually) so both of them are OK. If you have an important corrosion factor, or if you think the difference in money is not a problem in your case I would use 316, if not I would use 304.

Watson McDaniel Company low profile condensate return pump trap skids... The installation of a Pressure Motive Pump (PMP) requires a vented receiver for initial collection of the condensate. The receiver volume must be adequate to temporarily store enough condensate during the pumps discharge cycle when the pump tank is pressurized with steam. Vent line size must be sufficient to properly vent the flash steam and maintain 0 psig inside the receiver. Vent line size is based on both condensate volume and condensate temperature entering the receiver. Complete Packaged Systems are available. Simplex, Duplex, and Triplex systems include stand-alone PMP pumps with check valves and a vented receiver mounted on a common base. All components of the system are properly sized and pre-piped together; requiring only four connections to be made in the field. Duplex & Triplex systems can be used for increased capacity or in the event of a single pump failure. www.watsonmcdaniel.com 610-495-5131
