Surface feedback<br />
ASU (operation & maintenance by AL): no issue / Built and operated by Air Liquid<br />
Oxy-burners (AL equipment): no issue – start-up on air-combustion up to 30% load, then<br />
oxy-combustion up to 100%. Stable flames.<br />
Oxy-boiler: very smooth operation, oxy-boiler efficiency at least as high as air-boiler<br />
efficiency. No operating issues. Only problem is boiler degradation due to retrofit from under<br />
to over atmospheric pressure.<br />
Flue Gas Recycle: no issue<br />
Cooling tower : no issue<br />
<strong>Lacq</strong> compressor (reciprocating – 3 stages – wet): we had corrosion issues (mainly 3rd<br />
stage) because of nitric acid formation (dissolution of NO2 in water) due to liquid water<br />
carry-over from scrubbers towards the suction chambers. Scrubbers have been upgraded<br />
and compressor operating conditions adapted. The compressor now runs corrosion free.<br />
Dryers(AL molecular sieves): no issue<br />
Pipe from <strong>Lacq</strong> to Rousse (existing – 27km – carbon steel): no issue<br />
Rousse compressor (reciprocating – one stage – dry): no issue<br />
