Refining
API increases operational efficiency and improves
measurement accuracy using Micro Motion®
Coriolis fiscal measurement system
BENEFITS
•Overall Equipment Effectiveness (OEE) increased by
approximately 10 per cent
•Measurement accuracy improved by up to 0.3 per cent
•Minimal maintenance enables increased availability
•Enhanced safety by eliminating requirement to send
operatives onto tank roofs
Customer
The Falconara Marittima (Ancona) refinery is located on the
Adriatic coast of Italy. Built in 1950 the refinery is part of API
Group (Anonima Petroli Italiana SpA). The site covers an area of
over 700,000 m² and the refinery has a capacity of 3,900,000
tonnes per annum. Access to the refinery from the sea is provided
by marine terminals which can accommodate tankers from 1,000
to 400,000 tonnes.
Application
Metering system based on Coriolis mass flow measurement. The
system is used to provide accurate measurements of hydrocarbon
deliveries from large storage tanks at the refinery to waiting
tankers at the sea tanker loading terminal.
Challenge
The fiscal measurement of deliveries was being calculated by
monitoring tank levels. Although the company had installed the
latest level measurement technology, the measurement errors
were considered to be unacceptable. The inaccuracies were
affecting both taxes paid and profit margin, with the average
margin of error calculated by API at 0.5%. API needed a turnkey
metering solution that would increase the accuracy of fiscal
measurements at the tanker terminal.
Solution
Emerson provided a metering skid based on its Micro Motion®
Coriolis mass flow meters. The skid was provided fully complete,
