Fouling characteristics of organic fluids

Creator:: Oufer, Lounes
Abstract:: A systematic study of the fouling characteristics of organic fluids was conducted in an annular test section. The study consisted of four main parts. First, the effect of key factors such as surface temperature, velocity, concentration, and oxygen on fouling from the system styrene-heptane-polystyrene was investigated. While surface temperature increased...

A study of two-phase liquid-liquid flow in pipes

Creator:: Soot, Peet Mati
Abstract:: The pressure drop for two-phase liquid-liquid flow is theoretically predicted for each flow regime. Empirical correlations, which are applicable in all flow regimes, are also presented for holdup as well as pressure drop. The experimental study covered bubble and drop flow regimes. The discontinuous phase was injected by nozzle into...

Fouling characteristics of a desalted crude oil

Creator:: Lin, Dah-cheng
Abstract:: The fouling characteristics of a desalted crude oil were investigated in a systematic investigation. There are two main parts in this study, the dry bulk tests (dehydrated crude oil) and the wet bulk tests (to which desalter brine was added). Three barrels of desalted crude oil provided by Amoco Oil...

Fouling characteristics of cooling tower water containing corrosion inhibitors

Creator:: Santoso, Elisabeth
Abstract:: The fouling characteristics of cooling tower water containing various corrosion inhibitors and other additives on heat transfer surface have been investigated. Corrosion inhibitors investigated included zinc-chromate and phosphates. In addition, additives including polyacrylate and phosphonate (HEDP and AMP) were used to determine their effectiveness as antifoulants. The tests were conducted...

Heat transfer between moving beds of solids and a vertical tube

Creator:: Obuskovic, Nevenka S.
Abstract:: Heat transfer to moving packed beds of solids has been studied extensively but predictions are usually specific to the experimenter's own equipment. In order to obtain a more general predictive equation, the heat transfer coefficient was measured for a single vertical tube immersed in a moving packed bed of glass...

The effect of copolymer and iron on the fouling characteristics of cooling tower water containing corrosion inhibitors

Creator:: Abu-Al-Saud, Abdullah A.
Abstract:: Various antifoulant treatment programs and the considerations necessary for the effective use of such programs were examined. Two different groups of tests, with and without iron contamination, have been carried out on the effectiveness of several of the state-of-the-art copolymers (PA, HEDP, AA/HPA, AA/MA, SS/MA and AA/SA) in the inhibition...

Nucleate boiling of various fluids in a thermosiphon reboiler

Creator:: Oufer, Lounes
Abstract:: A study of nucleate boiling of water, four alcohols and three ethanol-water mixtures was conducted in a vertical thermosiphon reboiler. The test section consisted of a 1/2- inch diameter electrically heated stainless-steel rod jacketed by a 15-inch long pyrex glass tube. Two different inside diameters of the glass tube corresponding...
