Capacity :  350/m³

Location :   NC1 LOTTE CHEMICAL TITAN PASIR GUDANG JOHOR  

  1. To provision skilled technician(obtained AESP & safety inducted) consumables to carry out the general cleaning by proper high speed Mastra Submersible Pump , 3 phase oily water separator and 7,000 psi electrical driven hp pump (4units), minimum 12 pax workers in a team, with 1 team minimum to perform the cleaning job (10 blasters + 1 foreman + 1 safety coordinator) – to work at PT13 – 12 hrs shift
  2. Dismantling works as per operation’s list prior to any works commence (spade or blind flange will be supply by
    client ). If any may incurred.
     To remove pit cover using lifting crane upon completion of mechanical works. Any damaged cover of PT 13 should be replaced by FST.
     To provision scaffolding with the size of 14m x 15m x 4m in accordance with LCTM approved execution.
     To use hard canvas to minimize rainwater carryover to 2PK-5500-PT13 during cleaning progress
     To spray oil dispersant chemical on the wall and bottom part of pit and to soften the wall attached sludge
     Finally a high pressure hydro jetting will be applied at 5 000psi to remove all accumulated hardened scale of internal wall & bottom part of pit , also wash down the entire surface of PT13 for better preparation .
     Upon completion of pumping out, removal of oily sludge will be carried out using ultrafiltration system of 3 phase separator which designed as a complete, fully automated, semi-automated skid mounted system that filters contaminants down to 0.05 micron particle size. The decanter system will suck oily-water + sludge from pit by means hydraulic sludge recovery system 1800lpm direct to buffer tank. Separation done here with high speed blade and sent to lube pump for separate the oily-water & sludge.
     The separated dry sludge cake containment will collected in the separator using dehydrator will store in open top drum provided by LCTM for disposal and oily water will directed to another pit for treatment.
     Moisture content of the sludge should be less than 75% at a minimum level.
     To reinstall 2PK-5500-PT13 pit cover upon completion of cleaning.
