Preparation of fast and highly active oil absorption resin

With the increasing mileages of in-service oil pipelines, probability of overflow incidents rises gradually due to natural and human factors. Consequently, it is necessary to develop a kind of fast and high oil absorption resin to minimize losses and hazards related to oil leakage. By using the suspension-polymerization process, various long-chain acrylates, butyl acrylate and styrene are used as monomers to generate the fast and high oil absorption resin through copolymerization. In addition, impacts of monomer classifications, proportions and volume of crosslinkers to saturated oil absorption capacity and rate are reviewed. Relevant research results show that decyl acrylate is more suitable for monomers with long-chain esters; optimal mole ratios of decyl acrylate, butyl acrylate and styrene are 2:5:0.9, and optimal volume of diethylene benze deployed is 1%. Resins generated are in sponginess configurations with outstanding performances in absorption of crude oil. These resins may have oil absorption capacity of 9.0 to Russian crude oil and may reach saturated absorption within 10-20 min. In addition, these products may contain approximately 90% of oil with excellent performances in recovery of floating oil on water surface.
