    SNORGY, I am using the SMYS of 316, the material is dual rated, however we are using the higher SMYS for calculations. konman, Thanks for the reference, the issue is that the "legacy" piping was installed using CSA Z662-07, problem is that the engineer that signed off on it, wasn't, in my...

    CSA Z662-07 and Stainless Steel

    I have a client who is building some surface piping on a water injection system. Code is CSA Z662-07. In the past they have built all of this piping from Sch 80 316/316L material. I was asked to approve a new installation that would be "identical" to the installations they have done for the past...

    I'm designing a new piping system for a client, They have an inhouse specification that indicates that the maximum allowable pressure drop in a pipe carying dry fuel gas is 11.5kPa/100m. The majority of the piping system meets this requirement howeve there are short sections of pipe near the...

    What should I do

    The recruiter was from a third party head hunter company, From him, of course the job was sunshine and fresh apple pie! The manager did a good job of selling me on all of the responsibility and extensive world travel that I would be involved in. In their defense, I started in September and the...

    What should I do

    I ended up renting the house I own for enough to cover my rent in Calgary. (So in the end the net expense is the same as if I was living in the house I own.) Company A was not able to keep me busy enough with the project they had promised (welcome to 2008/2009) and I was extremely bored so I...

    I gave my two weeks notice at my firm 1 week ago, I am leaving because the company i am working with couldn't keep me busy and I was very bored at work. After I gave my notice no one communicated to me at all last week. On Thursday I sent my boss a transition plan that wrapped up all of the...

    Using Table A3 in B31.1

    I have a pretty simple question. I have a Design Temp of 70degC (158degF). When obtaining the Max allowable stress from table A3 in B31.1 can I interpolate to get S at my design temperature. ie. From -20 to 100F S= 16700psi Up to 200F S= 14300psi Can I interpolate and use S= 15308psi? Or...

    What should I do

    I appreciate the answers, but just a few clarifications Greg, I am not being obstanant over the price of my house. If you must know I bought a year ago, I listed it 10% ($38,000) below what I paid in October of 07, and for $8000 less that the appraised value (appraisal done in September 08)...

    What should I do

    I'm looking for some career advice. I recently left Company A to join Company B, this involved relocating to a new city. Unfortunately with the housing market slide in Alberta, I have been unable to sell my house in my old town and am stuck paying $5000/month between mortgage in the old...

    Rich Amine Filter Logistics

    Thanks Maddocks, Our plant is also located in Alberta. Currently the plan was to drain the dirty side of the exchanger to the closed amine drain (CAD), which ends up in the sump. If needed we would potentially push it to the CAD with fuel gas. From the sump the amine is already pumped back to...

    Amine Contactor Off gas cooler

    Thanks for both posts. I guess the sense I get from both is that the major benefit of cooling the gas is water removal and the associated reduction in load that is passed on to the refrig system. This is consistant with my thought on the matter, where the difference in opinion has occured is on...

    Amine Contactor Off gas cooler

    Some debate at our plant regarding cooling of the sweet gas from the contactor. Original design of the plant was (following sweet gas flow) contactor --> knockout (to recover amine) --> Dehydration (glycol, Refrigeration, and Lean Oil) We are installing two new contactors, and the operations...

    Rich Amine Filter Logistics

    Hi all, I've got a question pertaining to the installation of a Rich amine filter in an existing facility. The question pertains to what to do with the amine in the filter housing when it comes time to change the filters. Filter will be a standard horizontal cartridge type housing. We are...

    MDEA Amine regenerator unit filters-propritary vs conventional

    gosooners, These numbers are standard design basis for most lean amine filtration systems. Currently I am designing a carbon unit with a capacity of 10% of our lean flow or approximately 90gpm. Using superficial velocity of 4gpm/ft2 this translates to a tower diameter of ~7.5ft. Not...

    MDEA Amine regenerator unit filters-propritary vs conventional

    gosooners, Typically one would go with a cartridge filter, or perhaps even bags. Contact a filter manufacturer to get an idea of the products that are out there. When it comes to filters the simpler the better. Remember that during start up and upset conditions you will be changing filters...

    Liquid Entrainment/Carryover from Inlet Separator

    I should clarify. I am hoping to run a single test to determine the extent of liquid carryover, I am not looking to install monitoring systems at this time. I am looking for a standard for sample collection, I've heard from others that ASTM has such a standard/procedure but I am having trouble...

    Liquid Entrainment/Carryover from Inlet Separator

    Does anyone have any experience measuring entrained liquids from a gas stream. We know we have a liquid carryover problem from our inlet separators but would like to quantify and identify the liquid. We are proposing taking a gas sample and analyzing with a Hot GC run to charachterize the...
