Leaching Study Conducted on Phenolic Novolac ResinCoated Proppants JPT
The PU RCPs showed leachant levels between and by weight. Fig. 2 provides a summary of the comparative leachability study of the phenolic novolac RCPs versus PU RCPs (PU1 and PU2) tested at 250 o F. The total leached material from each RCP has been averaged over the three pH conditions as it was observed that the extent of RCP
Natural Sand Proppant Watch on The highest quality raw sand from our Northern White deposits exhibits the highest crush resistance of natural substrates. The chemical composition exhibits over 99 monocrystalline quartz. The shape (sphericity and roundness) and strength result in downhole durability and high conductivity.
Leaching Study Conducted on Phenolic Novolac ResinCoated Proppants JPT
The first curable resincoated proppant (RCP) which Fairmount Santrol introduced 40 years ago has helped oil and gas operators solve costly proppant flowback problems. And the many phenolic novolac RCPs that the company has developed since then have become industry workhorse products.
Polymer composition for curing novolac resins Google
A polymer composition that can be used to cure a novolac resin at a lower temperature than conventional novolac curing agents and with reduced emission of volatile compounds is disclosed. The novolac curing agent polymer composition is prepared by mixing and reacting in aqueous solution a phenolic monomer and an aldehyde in the presence of a basic catalyst to forum an intermediate resin and

Aug 22 2021Washing is the simplest and lowest cost method for cleaning frac sand. DRY FLOW The dry flow is designed to remove moisture in the frac sand and size the sand into the various frac sand products. Typical Frac Sand sizes are 12/20 20/40 40/70 and 70/140 mesh. We have studied the two most common and generally accepted methods of drying frac sand.
Novolac resins are phenolfomaldehyde thermoplastic resins obtained under acid catalist conditions that cannot react further without the addition of a crosslinking agent. SBHPP novolac resins are supplied both in liquid or solid form with and without curing agent.
