sub'd
ur stack is something i really want to run! i love RPM and want to try x factor with drive or DTH for summer.

[Outside Backer]

as i said in the other log.

xfactor is iffy to me i cannot wait to see how this works out

Skipped the gym - am going to be soon.

Will move arms/delts to tomorrow and chest, back after. 3 days in a row, which I don't normally do w/ upper body, but oh well.

You know what actually works nicely before bed, is a li'l bit of glycine. It has a tendency to affect neurotransmitters and calm you down so you can relax. Beautiful stuff and really cheap.

You know I've tried glycine post-WO and found it made me REALLY sleepy. Wasn't sure why.

I'll use that sometime during the week.


Worked out chest tonight - but forgot my workout book in the car and I'm tired. Will update the weights tomorrow.

(Sin - saved a catalytic hydrogenation reactor from a death spiral at 4:30pm today. )

Tight.

Is this a counter-current packed bed (like a scrubber)? What was going wrong?

And yeah, glycine is like the "anti-stim", which is part of the reason why it's great for post workout, since activation of AMPK can hinder anabolism.

No - selective hydrogenation of an alkyne to an alkene (desired product from the plant is an alkene) - gas phase reactor.

Hydrogen tripled in flow rate in an hour - leading to undesired alkene loss (once the alkyne was consumed - H2 reacts w/ any other double bond) and potential temperature issues (exotherm) if not corrected quickly enough.

Turned out one of the branches in the H2 flow hierarchy had reached the engineering units high limit - which then made the value uncertain, which cause the flow to ramp up because it got confused (my term - not at all technical in nature).

Got the key to the control system from the process control guy and changed the engineering high limit by 50%. Value was just above the old high limit - flow began to come back to normal within a few minutes.

Operators loved me.

They do make partial hydrogenation catalysts for alkynes. I believe it's called a lindlar catalyst. Doesn't form alkanes. Probably not cost effective, though.

The question is now, why the hell was the H2 flow rate jacked up like that? You got the problem fixed today, but who's to say it doesn't happen while you're out. Band Aids heal scraped knees, knee pads prevent 'em. Sounds like this process needs a "knee pad".

Uhh...you guys really lost me with those last few posts...show offs!

It's chemical engineering - you wouldn't (or don't want) to understand.

Yeah - we have palladium doped with silver and something else for selectivity improvement. While Pd is expensive - it's at least available.
Most hydrogenation reactions in industry are done on Pd.

Plus the reactors are 20 feet tall and probably 6 to 8 feed wide. I forget the exact volume in ft^3 - but it's a lot.

Problems happen at all times. (But the worst issues seem to hit after midnight...)
I've earned the operators trust - so they call me when they run into things even if they make a move that corrects the situation.
They always call when they can't figure something out.

That's one big hydrogenator.

But I mean, if it's a common issue, that can end up costing the company money (or worse, a recall if it accidentally gets shipped out), then it might be something worth looking into as a process improvement. Sorry, I do a lot of QC work: angry customers come in, say our stuff's whack, and require an action plan to ensure it doesn't happen again.

Probably the latter.

Probably the latter.

First time I've seen this issue - have been the lead process engineer for this plant for 2 years now.

It would have just cost lost product - it wouldn't have made us go off spec I don't think. If we leak 0.4 mole ppm of the alkyne out the backend of the hydrofiner - we are off spec as it all fractionates in the product tower with the alkene.

We run to 0 alkyne on the outlet of the guard bed (2nd bed - lead and guard are in the same overall vessel, just have a top and bottom head in between).

Ok - back to the log. Posting workout results over the last 3 days next.

Edit - you want to talk QC, it's crazy for my product. Once it leaves the product tower - it's put directly into our pipeline and on into the customer's plants to make milk bottles. There are maybe minutes to divert the product to the flare. We have no off-spec tanks or anything - too high of a vapor pressure.
Hence - the lead process engineer better know his sh*t when he wants to make a change or when help is needed. No room for even the slightly miscalculation or mistake.
(Some things if I messed up on - pretty sure I'd be fired or demoted to an operator.)

Workout results.

4/18/8 - chest
bench - +5 lbs on first set, one rep short on 2nd set still at +5
dumbbell bench - + 5 (per DB) first 2 sets, next 2 were no change
dips - +10 lbs, only did 3 sets as my shoulders were bothering me for some reason
incline - same (started to get tired at the very end of dips)
cable crossover's - + 5 lbs

Thoughts - very good pump/soreness in my chest. Stabilizer muscles in my back became very sore - particularly rear delts. This hurt strength on the incline.
Tri's and forearms were ok - still more pumped than normal for chest day.
Finished with 20 mins on the elliptical machine.

4/19/08 - back/abs
lat pulldowns - +10 lbs on first set, normal on last 2 sets
reverse grip pulldowns (palms facing me) - + 10 lbs first set, normal on 3rd set
seated rows - +10 lbs all 3 sets!
t-bar - +5 lbs
forgot to do dumbbell pullovers
20 mins on the treadmill at an incline then 20 more mins on the elliptical
various crunches followed - focused on lower abs. Cramps on my bottom 2 abs again cut short the ab work (ugh).

Thoughts - very severe pumps in my forearms. Really hurt strength on the pulldowns - had to rest a while before the first set to go up on the reverse grip.
Pumps on my bi's - but nothing that got in the way. Forearms were the biggie then. This has happened before with supps that give me big pumps - Powerfull was one of the first.

4/20/08 - bi's/tri's/delt's/traps
Moved this back from Friday to Sunday to work chest and back first.
Biceps:
dumbbell curls - + 5 lbs all 3 sets
preacher curls - + 10 lbs all 3 sets (could have gone higher - but I have to be careful with preachers as I've hurt my elbow in the past)
concentration curls - same, bicep pumps huge by this time

triceps:
overhead dumbbell extensions (2 hand) - apparently been 2 months since I've done these, no clue why but same as back then
skullcrushers - +10 lbs all 3 sets. Last set was really tough.

delts:
side delt dumbbell raises - same, big pumps
upright barbell rows - same (have to be careful - can hurt my shoulder getting overzelous with these)

traps:
behind neck barbell shrugs - + 5 lbs
shrug machine (Hammer strength) - +10 lbs


Thoughts - severe arm pumps, but to be expected after working chest and back the 2 days before.
Very good delt and trap pumps. Forearms were OK during traps - pumped though.


This week will be a squirly workout routine. I'm going to the Jazz Fest in New Orleans next Saturday. I think lifting next weekend will be out.
So - am going to start the week with legs and then do chest and back on Wed and Thurs. May get in arms/delts/trap again next Sunday.

Thoughts on the stack:
No digestive issues on Drive. I chalk this up to using Bolic and other forselean supps off and on this year. Didn't go into Drive cold with regard to the Forselean.
Strength is going up fairly well. Seems similar to last time I took Drive. Pumps are pretty darn good.
RPM gives good energy thus far. I feel this is waning though. I'm way too used to stimulants. I need a break.
Unsure how long the X-factor takes to kick in.
Libido is up - I feel Drive is an excellent addition to PCT. Some acne increases on back and chest.

All in all - good first week on XF/Drive/RPM.
