Bulge-Resistant Coke Drum Patent Issued
Feb. 6, 2018 - HOUSTON ENGINEERING SOLUTIONS, LLC was granted US Patent 9,884,996 B2 for Bulge-Resistant Coke Drum by the US Patent Office. A coke drum apparatus including: a cylindrical section; a cap connected to an upper end of the cylindrical section; a bottom, and a knuckle connecting the bottom and the cylindrical section. The cylindrical section includes a plurality of arcuate segments attached together by vertical welds. Each arcuate segment includes a plurality of arcuate plates attached together by circumferential welds. The circumferential welds of each arcuate segment are offset from the circumferential welds of each adjacent arcuate segment. The patented design is intended to reduce the likelihood of developing the classic seam bulging observed in these large refinery vessels.

Three coke drum inventions unveiled
Houston Engineering Solutions, LLC of Houston, Texas unveiled three inventions that were recently developed to address the three most common failure modes in coke drums, namely skirt attachment cracks, shell bulging, and anchor bolt failures. A new skirt design, shell fabrication method, and drum anchoring system were introduced and discussed at the coking track of RefComm in Galveston on May 5, 2016. The three patented inventions can be utilized for designing new drums as well as for retrofitting existing ones. Currently, the new skirt and anchoring system are being implemented by operating companies in Saskatchewan and Alberta, respectively, to retrofit drums that have suffered recent failures. The announcement was made by Company president and inventor, Dr. Mahmod Samman.
