Hydrocarbon Processing - August 2022 - 55

HP Flashback
Intelligent microprocessor-based field devices rapidly replacing
older types of instrumentation in refineries and petrochemical
plants generate vast amounts of information that can
be useful far beyond the control room. New smart field devices
provide processing plants with a rich opportunity to improve
processes and reduce costs.
To bid or not to bid
B. Lenehan, May 1999
Bidding for large international projects can be a huge gamble,
with big stake money and no game rules. Presented here
is a simple method of collating and comparing requests for
proposals data in a ranking order for the tender selection committee
(TSC) to respond to. The bid/no bid responsibilities lie
firmly with the decision-makers in the TSC; however, by using
uniform data, it can quickly make balanced and consistent decisions.
Over time, the data collated can also be used for analyzing
the accuracy of the decisions.
Refinery air quality enforcement issues
S. P. Hampton and D. D. Bradley, August 1999
Throughout the latter half of the 1990s, petroleum refineries
have experienced an unprecedented level of enforcement actions
relating to environmental compliance. Air quality issues are at the
forefront of most refinery enforcement activity. By understanding
the regulatory requirements and managing compliance, refineries
can assess potential exposure before the next scheduled environmental
inspection. By reviewing these issues, refineries can
prepare for agency inquiries and address potential exposure areas.
Consider using hydrogen plants to cogenerate
power needs
J. Terrible, G. Shahani, C. Gagliardi, W. Baade, R. Bredehoft
and M. Ralston, December 1999
Many forces are reshaping the global hydrogen market; refiners
have several options to receive steam and electrical power
from a hydrogen plant. The supply of hydrogen, steam and electrical
power by third-party specialists can be particularly valuable
when these requirements are large enough to justify the
development of an independent supply infrastructure to serve
multiple customers. In several case histories, the varying scenarios
that simultaneously produce hydrogen, steam and electrical
power from a single production plant are discussed. The
integration of a steam methane reformer with various power
generation technologies such as a topping turbine gas turbine
and condensing turbine are explored.

Green Refi nery Challenges: Small-scale Sulfur Recovery
SPEAKER:
William (Bill) Echt
Technology Licensing Director
Merichem
Renewable fuels production is achieved by hydrotreating vegetable oils (HVO) and
waste greases. Within the new HVO processing technologies, there is co-production
of carbon dioxide (CO2
) and a small amount of hydrogen sulfi de (H2
systems. An amine unit can remove the unwanted CO2 from the process but also
removes the H2S. The resulting acid gas stream contains far less sulfur than is
practical to remove with a typical refi nery sulfur recovery unit (SRU) using Claus
technology.
A multinational oil and gas company based in Europe uses a proprietary sulfur
recovery technology to serve as the SRU. The liquid redox system uses a chelated
iron solution to convert H2
S.

sulfur from an acid gas with up to 7 mol% H2
