    CaCl2 LPG Dryer Rental

    I'm looking for a rental CaCl2 lpg dryer to handle about 6000-7000 bbl/d. Anyone out there know who might be able to supply this (anywhere in North America)? We'd probably be willing to buy one if it was available ASAP...like yesterday.

    Crazy handshakes

    I'm looking for some opinions from the group in regards to a couple of recent handshake 'incidents' that I experienced. Incident 1: Last week I popped into the office of a colleague. Also there was one of his direct reports. I was recently promoted and moved to the head office so I had not...

    Wells with plunger lifts and flow measurement

    I'm interested in understanding what impacts plunger lifts have on subsequent measurement of the gas (orifice meter installation downstream). I'm imagining the scenarios in my head but would like an experts viewpoint and maybe some rough numbers thrown in for fun.

    Orifice Meter - Causes of Bias

    I've got AGA3 in front of me and a bunch of other reference material but the answer I need is not jumping out at me. Could anyone out there give me the Readers Digest version of what factors contribute to bias errors as opposed to random +/- errors. Are there particular items that will...

    Automatic printing

    Is there a way to set up an EXCEL file to print a page automatically as per a specified schedule? What I am interested in doing is generating a hard copy report from an EXCEL file that is linked to DCS data. I would want it to print at 7AM every Monday morning. Any help is appreciated.

    EG vs. TEG added to refrig plant

    At a gas plant we have two trains. One train dehydrates the gas with a TEG contactor (9 trays). The other injects EG at the inlet of the refrigeration plant and takes it ou from a 3 phase low temperture separator. The operator has noted that the EG system has a lot higher glycol make-up...

    Removal of CO2 with MDEA

    I have been struggling with simulating (HYSYS) the sweetening of a 6mol% CO2, 2000 ppm H2S gas using 45wt% MDEA (operating at about 800 psig and 100F). Sweet gas has to be 2% CO2. The results that I am getting appear to be garbage. I am chalking this up to the fact that this is a tertiary...

    Efficiency of motors (synchronous vs induction)

    How would an induction motor (6000 hp, 6600 rpm, 4160V) compare to a synchronous motor (6000 hp, 1200 rpm, 4160V) in terms of power from the line to shaft power. I understand that there would be some slip with the induction motor but some rough numbers would help. Also, how much, if any, does...

    Small pilot operated valves

    Does anyone know of relief valve manufacturer that makes small pilot operated valves? I am specifically looking for 3/4 x 1 valves that meet ASME code. Farris, Consolidated, & AGCO don't make a pilot operated valve below a 1x2. I am looking at a lot of piping modifications to accomodate the...

    Gas filtering

    I am trying to track down a long-chain hydrocarbon contamination problem in a gas stream (it is contaminating one of my mole sieve beds). What devices/technologies are out there that could be used to sample a dry gas stream to collect and measure contaminants (oils). We have used millipore...

    PSVs...what's missing?

    I just wanted to start a discussion to solicit some opinions from the experts out there. While clicking through the various forums here I noticed that there are a lot of questions about PSVs (or whatever other acronym you want to use for safety relief valves). In fact, I'm pretty sure I...

    What to look for in a good VFD

    For a medium voltage (4160V) VFD in the 5000-10000 hp range (driving a synchronous motor coupled to a centrifugal compressor), what are some of the things to look at when selecting the drive and vendor? Anything to absolutely stay away from? I am having an electrical engineer do some research...

    Liquid Expanders

    I have some questions about the use and practicality of liquid expanders. The particular application would be to replace a valve at the bottom liquids outlet of a separator with an expander to recover the power (this is in a cryogenic natural gas extraction plant). The pressure drop is about...

    Tornado Diagram

    Does anybody have any hints on how to do a tornado diagram in EXCEL? I have my low, high, and middle numbers for each category but for some reason I am struggling with how to make the chart work...maybe I shouldn't be doing this on a Friday afternoon. Thx for any help.

    Looking for a chemical reaction to use as a heat source

    I am looking for a chemical reaction that can be used as a heat source to 'start' another reaction. I have to keep the application confidential but I hope by providing some of the criteria that I need satisfied, I may be able to get some help. -existing reaction is initiated by an electrical...

    Discharge from end of pipe

    If I have an open-ended pipe, oriented horizontally, discharging a fluid to atmosphere with known velocity can I estimate the arc that the fluid will travel (x distance for a given y) by using the basic physics formulas for projectile motion? If not, what would work? I am only looking for a...

    VFD on a Synchronous Motor

    I have an existing 9000 hp/1200 rpm synchronous motor (compressor drive) that I wish to couple to a VFD. Someone told me that this was a very unusual arrangement. Does anyone have any experience with this type of setup? What are the pitfalls or things to watch out for? Problems with the...

    New PSV with different body size

    I am replacing a conventional PSV with a pilot operated valve with the same specified capacity and set pressures. This valve vents to atmosphere. The original valve was a 2.5"x4". The new valve is a 2x3 with the same orifice size. This means I will need an inlet swage and a new short...

    Reboiler duty much higher than actual

    I have simulated both a demethanizer and deethanizer in HYSYS. Getting the towers to converge based on product specs (and actual GC data) is not a problem. However, the reboiler duty calculated by HYSYS is much higher than what is seen in the plant. For example the deethanizer duty is 90%...

    NDT of FEP/FRP Dual Laminate Pipe

    What methods,if any, are available for NDT of welds and detecting of permeation past the FEP liner into the FRP pipe in a dual laminate piping system?
