5 .2.1 Sample Main Flow Loop

The sample main f l ow loop provides pr imary mon i to r ing f o r hydrogen. The hydrogen sensors used (NE-*-6-1 and NE-*-12-1) a re electrochemical c e l l s t h a t p rov ide an e l e c t r i c a l s igna l p ropor t iona l t o t h e hydrogen p a r t i a l pressure i n t h e gas sample.

A pressure gauge (PI-*-8-1) d isp lays t h e sample l i n e pressure f o r system f l ow ca lcu la t ions and as a t roub leshoot ing a i d .

The main loop f l o w i s cont inuously monitored. The sample gas f low monitor ing system cons is ts o f an i n - l i n e laminar f l o w element (FE-*-7-1) and a d i f f e r e n t i a l pressure t ransmi t te r (FIT-*-7-1) which measures t h e pressure drop across t h e f l ow element. As sample gas f lows through t h e f l ow element, t h e t ransmi t te r generates a 4-20 m i 11 i amp s igna l p ropor t iona l t o t h e gas f l o w r a t e .

The f low through t h e sample main f l ow loop can be manually c o n t r o l l e d w i t h a f l o w con t ro l va lve (FCV-* - l - l ) . Th is valve,


i n conjunct ion w i t h t h e sample gas f low monitor i s provided as an a i d t o tank farm personnel t o ensure t h a t t he re i s adequate f l ow through t h e main sampling loop.

Before t h e sample gas enters t h e hydrogen sensor it i s f i r s t f i l t e r e d through th ree ser ies f i l t e r s . The f i r s t f i l t e r i s a 25 micron p a r t i c u l a t e and moisture f i l t e r , t h e next two a re .2 micron p a r t i c u l a t e f i l t e r s .

I f a decrease i n sample f low occurs, t he re a re two poss ib le causes: 1. No sample f l ow due t o sample pump f a i l u r e . 2 . Sample f l ow reduc t ion due t o a plugged p a r t i c u l a t e f i l t e r . The decrease i n f l ow due t o plugged f i l t e r s would most l i k e l y be a slow process, unless a tank event produced a l a r g e amount o f a i rborne contaminants.

The f i l t e r d i f f e r e n t i a l pressure i s measured across t h e se r ies combination o f t h e th ree i n l e t f i l t e r s . As t h e f i l t e r s become clogged t h i s pressure drop w i l l increase. This pressure drop i s measured by t h e d i f f e r e n t i a l pressure i n d i c a t o r (PDI-*-4- 1) . Since i t measures the pressure drop across a l l t h ree f i l t e r s i t i s no t poss ib le t o determine which o f t h e th ree f i l t e r s has clogged. It i s advisable t o replace a l l t h ree i f a problem develops.

A gas grab sample loop has been included i n t h i s design. It i s composed o f two ser ies connected gas c o l l e c t i o n cy l i nde rs which are connected t o t h e sample stream by two so leno id operated valves. This system al lows operator i n i t i a t e d o r automatic grab sampling. t h e operator c o l l e c t s gas specimens by depressing a push bu t ton .

Note however &at i n t h e case o f an au tomat ica l l y i n i t i a t e d grab sample cyc le upon a h igh hydrogen alarm, the tank farm area i s p o t e n t i a l l y unsafe. The operator should remotely v e r i f y low hydrogen l e v e l s be fore en t r y i n t o the a f fec ted tank farm.

Next, check t h e mechanical cond i t ion o f t h e heat t r a c e , thermocouple and associated i n s u l a t i o n . They a l l need t o be i n c lose prox imi ty t o the heat t raced l i n e . Next, ad jus t t h e c o n t r o l l e r se t p o i n t temperature above ambient and monitor t h e sensed temperature. I f it does not increase. t h e problem i s i n t h e heat t r a c e system and not i n t h e sensing system.

Since both t h e sample and c a l i b r a t i o n gas low temperature a l a r m funct ions are combined i n a s i n g l e l i g h t i t may be d i f f i c u l t t o determine which system caused t h e problem i f it i s sporadic i n na ture . b a t t e r y operated temperature recorder t h a t i s coupled t o t h e heat t r a c e thermocouple.
