02274 EFFECTIVENESS OF CORROSION INHIBITORS IN RETARDING PROPAGATION OF LOCALISED CORROSION

Product Number: 51300-02274-SG

ISBN: 02274 2002 CP

Author: A. Turnbull, D. Coleman, A.J. Griffiths, P.E. Francis, and L. Orkney

Publication Date: 2002

In many service applications excursions in solution chemistry, temporary loss of inhibitor, or transient increases in temperature may give rise to localised corrosion. To test the return of inhibition when the loss is remedied, the use of an artificial pit has been investigated using simulations of cooling water and of of oil production formation water.

02276 WHY CORROSION INHIBITORS DO NOT PERFORM WELL IN SOME MULTIPHASE CONDITIONS: A MECHANISTIC STUDY

Product Number: 51300-02276-SG

ISBN: 02276 2002 CP

Results of inhibitor performance at slug flow in a 101.6 mm inner diameter horizontal pipeline. Electrochemical Impedance Spectroscopy (EIS) and scanning electrom microscope (SEM) techniques are used to reveal that the strong bubble impact, high shear stress and turbulent intensity are the reasons for a poor performance of inhibitor.

A novel evaluation technique, based on an artificial pit electrode, has been developed for inhibitor studies. The first example is of three generic inhibitors, against localised corrosion. The second is of three industrial inhibitors against existing localised corrosion on a north sea production platform

02405 A CONVENIENT, LOW COST LABORATORY PROTOCOL FOR SCREENING SCALE INHIBITORS

Product Number: 51300-02405-SG

ISBN: 02405 2002 CP

Author: D. P. Wyman, R. D. Moll, J. D. Fox, F. J. Grad, and V. Mihalitsas

Publication Date: 2002

$20.00

A convenient protocol for screening the potential efficacy of scale inhibitors is described. All of the techniques used require relatively inexpensive equipment. Two types of scale are addressed in this paper, calcium carbonate and calcium oxalate, but the general procedures are expected to be applicable to inhibitor screening for others as well.

06442 POSSIBLE GLYCOL CORROSION IN NOMINALLY DRY GAS PIPELINES

Product Number: 51300-06442-SG

ISBN: 06442 2006 CP

Author: John S. Smart, III, Randy Roberts

Publication Date: 2006

$20.00

Pipeline quality gas is normally dried in Triethylene Glycol (TEG). This paper explores how TEG vapor can exist in a pipeline in a similar manner to water, and possibly lead to corrosion. TEG vapor can condense at long distances down a gas pipeline as the line cools.

The effectiveness of organic commercial migrating inhibitors on steel reinforcements corrosion. Four series of concrete specimens were cast. Two organic migrating inhibitors were applied. Free corrosion potential and corrosion rate of steel rebar were periodically monitored for five years. Results show that migrating inhibitors are not effective in reducing corrosion rate.
