    Although utmost care is taken during design to ensure an optimum life, we have heard that on an average, the life cannot prolong beyond 10~15 years if not earlier. Replacements would indeed be challenging; also we have come across some Licensor’s designs, wherein the lifting trunions for the coke drums have been advised to be cut after installation of the new drums. Wuld indeed like to hear from experts their experiences of coke drum replacements.

    Any information on how you have ‘dovetailed’ the bottom circular end of the chute with the rectangular mouth of the chute which takes the coke into the cokepit ? I understand that this may be telescopic; what about the gap between the circular outlet and the rectangular inlet? any sealent is recommended ? Experts opinion is solicited.

    I’d like to ask you instead, few questions on your experience on Hydrocyclones :
     
    1) What is the Liner Material
     
    2) Any recommendation on the suppliers? We are presently in market for installation in our DCU; however suppliers are observed to be very few eg. the likes of Weir, Krebbs…

    What is the experts opinion on installation of a common HPU for Coke Cutting (hydraulic winch & rotary joint for the cutting tool) and Top & Bottom Deheading Systems?
    Some of the installations use a common HPU for both. Rather than have seperate HPUs its better to optimise on one.
    Experts’ advise is requested.

    Any established data on Naptha Injection for Impeller cleaning, frequency of wheel wash and problems encountered during such cleaning operations? Do you have wet gas compressors with on-line naptha injection installed?
    Experts advise is requested.
