Title: Corrosion monitoring.
Inventor: EDEN DAVID ANTHONY THE UNIVERS
IPC: G01N17/00
Filed: 1987-05-11
Abstract: PCT No. PCT/GB87/00310 Sec. 371 Date Nov. 14, 1990 Sec. 102(e) Date Nov. 14, 1990 PCT Filed May 11, 1987 PCT Pub. No. WO87/07022 PCT Pub. Date Nov. 19, 1987.A method and apparatus for detecting and measuring localized corrosion of a metallic surface is described. An array of electrodes fabricated from the same material as the metallic surface is exposed to the same corrosion conditions as the metallic surface. The coupling current between two electrodes of the array is measured, and the electrochemical current noise originating in the electrode array is measured. The two measurements are compared, the electrochemical current noise increasing as compared to the coupling current as the degree to which corrosion is localized increases. The electrochemical current noise originating in the coupled array electrode and the associated electrochemical corrosion potential noise are produced by the natural corrosion processes. The corrosion current is measured by comparison or correlation of the electrochemical current noise and the electrochemical potential noise, the electrochemical potential being measured by means of a third electrode in the array, a reference electrode or a relatively inert electrode. Comparison or correlation of the electrochemical potential noise to the electrochemical current noise provides a resistive noise or impedance, which is inversely proportional to the corrosion current. The corrosion measurement or metal penetration rate is then obtained from the measured corrosion current, as provided by the resistive noise or impedance noise determination, but modified by the degree of localization, as measured by the electrochemical current noise and coupling current determinations.

Abstract: In the transmit mode, a converter is first driven with a modulated carrier frequency, the modulated carrier frequency being predetermined by the inherent frequency (f1) of the converter during a first modulation period (t1) and thereafter being predetermined by a frequency (f2) outside the inherent frequency of the converter during a subsequent second modulation period (t2). During the reception of the reflected echo signal, the echo signal reconverted into an electrical signal by the converter (W2) is supplied to a phase-locked loop (PLL) via an amplifier (V). The output signal (X) of the phase-locked loop (PLL) is supplied via a monostable flip-flop (MF) to an evaluating stage A which responds to the falling edge of the pulse (Y) after the monostable flip-flop. In this manner, the output pulse (Y) of the monostable flip-flop is synchronised with the output pulse (X) of the phase-locked loop when the phase-locked loop loses lock whilst when there is no loss of lock, a falling pulse edge occurs delayed by the pulse duration of the monostable flip-flop (MF). The pulse duration of the monostable flip-flop corresponds to the modulation period t1 plus a delay  DELTA t which is selected to be of the order of magnitude of the longest possible-lock on delay of the phase-locked loop (PLL). <IMAGE>

Abstract: Method and appara­
tus for removing oil-based 
drilling mud from drill cut­
tings in order to prepare the 
drill cuttings for an envir­
onmentally safe disposal in 
the sea. A solvent in the 
range of solvents which 
may be condensed by am­
bient seawater and vapor­
ized by heat internal com­
bustion engine coolant is ut­
ilized in the process. The 
method of this invention in­
cludes the steps of trans­
porting oil-based mud-lad­
en cuttings to a solid feed 
tank (10) wherein the oil-­
based cuttings are subjected 
to turbulent mixing to leave 
the surface of the cuttings 
substantially free of oil. The 
cuttings are then transported to a countercurrent flow column (20) and subjected to countercurrent, laminar flow of sol­
vent in order to separate oily solvent and fines smaller than a chosen diameter from the heavier solids. The heavier solids 
are cleaned of any remaining oil-based muds, separated from cleaning solvent and ultimately returned to the sea environ­
ment. The method include the further step of treating the oil-based mud laden solvent for separation of remaining solvent 
for return of the solvent to the continuous process and for recycling the recovered oil-based drilling mud into the drilling 
mud sytem.
