Sterilos corrosion solutions

Microbial Corrosion  In  The     Petro  Industry       Presenta(on  at  the   Oil  &  Gas  Summit  &  Exhibi=on     KUWAIT   12  -­‐  15.  February    


What Are  SRB?   SRB  are  Sulfate  Reduc=on  Bacteria  that  are  anaerobic  and  can   survive  in  a  crude  oil  environment.           These  SRB  are  causing  increasingly     expensive  and  disrup(ve  problems    in  pipelines  and  pipeline  related    machinery.       There   is  much  discussion  as  to  why     all  of  a  sudden  so  much  of  these     bacteria  are  found,  but  currently    there  are  no  sa(sfying,  concrete    answers.      


Metal Ea=ng  Bacteria   As  SRB  are  "ea(ng"  the  sulfate  out  of  the  steel,  the  structure  of   the  steel  weakens,  and  piLng  of  the  metal  begins.  Addi(onally,   SRB  produces  H2S  in  the  process,  which  is  responsible  for   increased  corrosion.        Once  piLng  begins,  the  SRB  seOle   in     the  piLng.  When  the  pipeline  is   pigged,   the  SRB  are,  in  most  cases,     undisturbed,  since  the  pig  is   merely  passing  over  the  SRB,   without  effec(ng  it.  


Silver Kills  Bacteria   In  ancient  history,  the  Greeks  added  silver  coins  to  their  drinking   containers  to  keep  them  germfree.      

What they  knew  in  ancient  (mes  has  since  been  scien(fically   proven.     For  example,  during  the  20th  century  the   Swiss  biochemist  Nägeli  published  scien(fic   ar(cles  about  the  influence  of  silver  against   bacteria.    

Silver has  come  to  rival  the  value  of  gold.  It  is   increasingly  added  in  small  amounts  to  such   products  as  salves  or  cosme(cs.      

But to  date,  it  has  been  far  too  expensive  to   make  a  breakthrough  in  the  mass  market.  


Sterilos Microsilver  Eliminates  SRB   Sterilos’  new  inven(on,  aXer  15  years  of  development  with   Fraunhofer  and  the  Max  Plank  ins=tute,  is  a  microsilver   concentrate,  which  is  100  =mes  more  effec(ve  than  all  other   nano-­‐  or  micro  silver  products  in  the  market.           The  effec(veness  of  silver  is  thus  increased  while  the  cost  of  raw   materials  is  thereby  reduced.    

This an(microbial  protec(on  func(on  can  now  deliver   uncountable  cost  savings  and  efficiencies  for  the  petro  industry.        


What is  Sterilos  Microsilver?   Sterilos'  scien(sts  and  engineers  have  developed  a  formula  for   changing  the  microsilver  matrix  via  a  proprietary  procedure  in   the  way  that  they  developed  a  spongy  concentrate.                    

The an(microbial  efficacy  has  been  confirmed  in  several   independent  tests  (e.g.  Quality  Labs  in  Germany).          


Key Product  Features   •  Sterilos  developed  a  highly  linkable  concentrate,  which  allows   our  enhanced  microsilver  addi(ve  to  evenly  suspend  in   applica(on  materials  (e.g.  pipeline  coa(ng,  paint,  plas(c).     •  It  has  a  broad  an(microbial  effect  against  bacteria,  including   SRB  and  other  microorganisms.   •  Once  deposited  it  maintains  a  long-­‐term  an(microbial  effect   over  the  life(me  of  the  host  product.   •  Physical  process  -­‐  no  chemical  impuri(es  (safe  and  non-­‐toxic   to  humans).   •  It  does  not  affect  the  proper(es  of  the  materials  being  applied,   e.g.  pipeline  coa(ngs.   •  Highly  resistance  to  harsh  and  corrosive  chemicals   •  Stops  microbiological  induced  corrosion  (MIC)  


How Does  It  Work?   The  silver  ions  (AG+  ions)  aOack  the  cell  walls  of  the   microorganism  thereby  eradica(ng  the  bacteria.               The  Sterilos  microsilver:      

•  prevents cell  dividing  (mitosis)   •  stops  the  cell  producing  energy     •  stops  DNA  replica(on  (prolifera(on)

As a  result,  the  Sterilos  Microsilver  stops   the  growth  of  harmful  bacteria  and   biofilms  on  the  treated  surface  and   hinders  cells  from  developing  defence   and  resistance.
