Patent number: 9719035Abstract: Corrosion induced by the presence of naphthenic acids in hydrocarbon fluids, particularly where such fluids are at elevated temperatures, may be inhibited or controlled through use of corrosion inhibiting compositions comprising a combination of a minor portion of a phosphorus-based constituent and a major portion of a sulfur-based constituent, nitrogen-based constituent, or combination thereof. In another embodiment the sulfur-based constituent and/or nitrogen-based constituent may be used without any phosphorus-based constituent. Where the compounds are appropriately selected, the compositions may inhibit corrosion to a degree comparable or nearly comparable to the inhibition provided by an equal amount of some conventional phosphorus-based compounds alone, but are significantly less likely to impair catalyst activity in downstream cracking and refinery operations.Type: GrantFiled: June 24, 2013Date of Patent: August 1, 2017Assignee: Baker Hughes IncorporatedInventors: Michael J. Zetlmeisl, Bradley G. Harrell, Bradley G. Borgard, Scott Bieber

Publication number: 20120066964Abstract: Exhaust emissions resulting from the combustion of hydrocarbon fuels in compression ignition engines may be reduced using a homopolymer that may be polyisobutylene, polypropylene, and/or hyperbranched polyalpha-olefins. The homopolymer may have a molecular weight of from about 1600 to about 275,000. Optionally, an alkyl nitrate such as 2-ethylhexylnitrate (2EHN), and/or a peroxide, such as hydrogen peroxide, may also be used together with the homopolymer. Both NOx and particulate matter emissions (PM) may be reduced using ppm quantities of the additive compositions; alternatively, NOx emissions may be lowered or reduced while PM emissions do not substantially increase.Type: ApplicationFiled: June 17, 2011Publication date: March 22, 2012Applicant: BAKER HUGHES INCORPORATEDInventors: Bradley G.

Patent number: 7935246Abstract: Metal additives to hydrocarbon feed streams give improved hydrocarbon liquid yield during thermal cracking thereof. Suitable additives include metal overbases and metal dispersions and the metals suitable include, but are not necessarily limited to, magnesium, calcium, barium, strontium, aluminum, boron, zinc, silicon, cerium, titanium, zirconium, chromium, molybdenum, tungsten, and/or platinum, overbases and dispersions.

Patent number: 4196057Abstract: A cold end corrosion rate measuring probe consisting of a corrosion rate meter probe modified by the addition of a cooling jacket and a temperature measuring device such as a thermocouple. The probe is adapted to be flush mounted in an exhaust line or flue. A coolant, e.g. water, is circulated through the jacket to bring monitored gas to its dew point, at which point, a corrosion rate measurement can be made. The dew point may also be indicated by increased conductivity across two adjacent electrodes of the probe, e.g., the reference and test electrodes. Measurement of corrosion rate and accompanying dew point can be correlated with sulfur trioxide concentration in flue or exhaust gases and hence enables predictability of occurrence and location of "cold end" corrosion, which also indicates inhibitor effectiveness.Type: GrantFiled: August 31, 1978Date of Patent: April 1, 1980Assignee: Petrolite CorporationInventors: Walter R. May, Michael J. Zetlmeisl, David F. Laurence
