TEG dehydration is really a problematic process and requires close monitoring. Some already have shutdown facilities especially offshore. Pressure swing adsoption(PSA) is becoming popular as an option to TEG. Aside from moisture, PSA can remove Nitrogen and CO2 in an unmanned stations. 209larry

rcontractor, Maybe you should change your transducer. Check what is the signal output and inquire from other pressure transducer vendor. You might find a specification that matches your requirement. Maybe a pressure transmitter can do the job. rgds, 209larry

leggy, You can use control valve to measure flow if you have critical flow condition and there is no phase change which I think is not possible since you have saturated condition. An alternative is to relocate your US flow meter way below your vessel to prevent gas breakout. Three to four...

LPHS, You require multiphase pump of screw type not centrifugal pump. The pump is designed to function as compressor and pump. Regards, 209larry

Chowles, Crude oil with high asphaltene content has a high probability of having permanent emulsions. Asphaltenes are usually in cluster formations with resins and oil. Asphaltene clusters when crushed and opened by mixing or by passing thru chokes, orifice and control valves, attracts...

cessna98j, You can extract blocknames, coordinates and other attributes using ATTEXT to a text file in comma delimeted format *.cdf or space delimited format *.cdf which you can convert to spreasheet or database format. You have to prepare a template which will include BL: X , BL: Y and Bl: Z...

Fritzfrederix, P&IDs in Autocad with well-engineered block attributes(visible and invisible) can save up to 65% of detail engineering manhours and gives a better accuracy than 'manually' cross-referenced construction drawings and documents. With a mouse click you can retrieve and generate...

mborges, Depends on the manufacturer you want. Fisher and Masoneillan will offer you diaphragm actuators while Valtek, Bettis, rotork, hytork will offer you piston actuators. Manufacturers have the right models for you. What matters are cost, delivery and previous experience with the control...

GGmurphy, If vessel is to be constructed, load cells is a good alternative to radio active level transmitters. rgds, 209larry

chowles, Emulsions are actually asphaltenes, and not formed by mixing oil and water. It structure contains oxygen, nitrogen and sometime sulfur. You cannot separate as oil and water. These are the characteristics of your reservoirs. The only way to combat these is reduce flowrates from the...

Lis, Ozonation and hydrogen peroxide treatments , followed by filtration have been found effective in oxidizing both single, double and triple bonds H-C including aromatic hydrocarbon. As long as bromate formation is not a problem they are good treatment solutions. They are use to disinfect...

Hi garcianos, My understanding is full bore refers to ball valves, full port refers to globe valves whose orifice size same as the PIPE ID. Rgds, 209larry

tvcad, g-lobe, g for the flowpath and lobe for the shape. 209larry

PoorRod, It looks like the first chimney is seamless pipe while the other one is a spiral weld. 209larry

kristof79, If you are familiar with ATTEXT command,you will be able to extract the block insertion point coordinates by adding BL:x and BL:y into your extraction text. You should add a unique attribute i.e. CONVEYORNUMBER so other block coordinates will not be extracted. You can format the...

The requirements are air locked doors (two door entry) air duct damper and manometer. Design will be similar to centralized HVAC system. But the question is how would you kill aspergillus spores in fresh air make-up, can it be killed by ozone or UV? 209larry

Put the insertion points; xaxis and yaxis in your text file. You can sort using this data by excel if your bom is tabled not scattered. With regards to crashing since excel is faster than Autocad insert MSGBOX ( ,VBOK) to stop Excel macro processing. You can click OK when Autocad has finished...
