A LARGE CHEMICAL AND PLASTICS COMPANY OPERATES ONE OF THE LARGEST REFINERIES IN THE U.S. PRODUCING GASOLINE AND FUEL COMPONENTS, LOW-SULFUR DIESEL, JET FUEL AND LUBRICANTS HAD TO REPLACE STRING WOUND CARTRIDGES TO PROTECT THE DOWNSTREAM EQUIPMENT.
A Hydro Desulphurization unit removes sulfur from cat cracker feed. The unit receives feed from a crude unit and feed stream from a coker fractionator, which takes feed stream from heavy coker gas oil. This effectively processes heavy gas oil, heavy vacuum gas oil, medium vacuum gas oil, and heavy coker gas oil.
The string wound elements used in the filtration process were breaking down and infiltrating the reactor. Jonell System’s challenge was to create a solution that would replace the string wound elements to solve the particulate contamination problem and prevent the particulate matter from reaching the reactor. A special cost effective cartridge needed to be developed.
Engineers at Jonell Systems field and lab tested the exact media layers required in the LiquiPleat series filter design to eliminate all contaminants from reaching the reactor. With element design enhancements such as a stainless-steel core, concern for corrosion was substantially diminished. The media variation increased the life of the element and eliminated monthly change-outs.
Jonell Systems used the LiquiPleat Series which consisted of various grades of cotton medias to suit process needs. This media combination effectively removed the contaminants, substantially reduced the frequency of change-outs, improved efficiencies within the operation and did not disintegrate to create further contamination.
Our customer successfully prevented contaminants from reaching the reactor, which improved operations, uptime and resulted in lower maintenance costs.
