HYDROCARBON REMOVAL FROM AMINESDEMONSTRATED EXPERIENCE

摘要

Several large Operating Facilities are now using the latest Technology from MPR Services, Inc.For the removal of hydrocarbons from their amine systems. These HCX TM units have been installedand operating from six months to over five years. The measured results show that the new Technologymaintains a hydrocarbon content of less than 10 ppm (the maintenance level) when the amine system isexperiencing normal hydrocarbon incursion and a recovery period (return to maintenance level) of lessthan thirty days after a major operating system upset (large single event hydrocarbon incursion). Priorto installation of HCX, the amine systems had continuous hydrocarbon levels of 200 ppm to 6,000 ppm(at which point foaming created a purging of the system by amine carry-over with new amine thenbeing introduced).The amine removal media is fully “regenerable” using hot water (steam condensate) and is PLCor Timer Controlled for automatic switching between the absorption period, the rinse (aminedisplacement) step, and the hot water regeneration step. The removal media life is exceeding threeyears before replacement is required.The demonstrated results after several years of operating experience show that maintaining acontinuously low level of hydrocarbons reduces foaming, reduces amine losses, improves aminesystem performance and reliability, and greatly reduces carbon filter change-outs and the associatedmaintenance labor and solid waste disposal.
