SHELL SIDE FOULING INNOVATION LAUNCHES DEMONSTRATIONS
T
ube Tech International has announced that its multi-million- dollar Shell Side Jet innovation
has begun live demonstrations to the open market. The innovation, which is the result of a multi-million-dollar R&D investment, guarantees to remove fouling from the outside heat transfer surface of shell and tube exchangers for the first time. Developed by Tube Tech
International, with R&D funding from the Horizon 2020 programme, via the SME Instrument, Shell Side Jet has been created to meet the demands of the petrochemical market for a solution that can clean in-between shell side tubes. Its makers believe it will be the only technology able to tackle shell side fouling with guaranteed results.
“The technology includes a Derek Sumsion, R&D Manager for
Tube Tech International, says: “The live demonstrations of our Shell Side Jet solution is a huge milestone for us, prior to the system’s launch in March 2020. We have spent years researching and developing solutions to the industry’s most difficult fouling challenges, and we are proud to be demonstrating this unique service, which we believe is the first of its kind.
detection system that is able to indicate bent tubes and severely fouled areas, protecting the asset and ensuring a more precise clean. We are also able to offer the client detailed digital reports that include information such as the distance of baffle plates, location of damaged or broken tubes, volume of fouling, photos of before, during and after the clean, and an intuitive heat map. “Using this system, we can restore
assets to near design thermal efficiency, in turn reducing CO2
emissions and
improving productivity, which will ultimately save millions of dollars a year for refineries across the world.” l

MICRO-METERING PUMP FOR GAS ODORISATION at up to 12,500Nm³/h
A
ccording to the German Energy Agency (dena), biomethane production in Germany may
increase as much as 10 times over – from currently 9 terawatt hours to about 100 – by 2050. What is more, natural gas is the most important energy source for private households and accounts for 44% of the heating market. Before natural gas or biogas
is fed into commercial supply networks, it must have an odorant added to it. Odorants serve as a warning in case of leakage.
Since the last few years have been marked by a trend toward decentralised production, Lewa has added the MAH 4 size to its micro-metering pump portfolio as a proactive

measure for meeting the expected increase in demand. The new unit can be used for odorising with mercaptans or tetrahydrothiophene at a throughput rate of up to 12,500Nm³/h. The pump covers the flow range from 200 to 250ml and can be used as a cost-effective solution in accordance with DIN-EN 1333 for gas networks up to PM 16. “Back in early 2018, we started getting more requests for odorising gas volumes of approximately 12,500Nm³/h, to the point where it just made sense to design a pump specifically for that amount,” says Walter Richter at Lewa.
“The right way for us to respond
to this trend was to add an intermediate size, the MAH 4, to our hydraulically actuated
and solenoid-driven micro-metering pumps from the MAH, MBH and MLM series. The new size meets the requirements for this range exactly.” The new unit closes the gap
between the MAH 3 and the MAH 5 – something that had previously been done using the larger MLM 15 series. However, the stronger stroke solenoid made that design over- dimensioned and less cost-efficient in some cases. Neither the MAH 3 nor the MAH 5 units from the same series were cut out for the job. There was always one of two problems: either they could not manage to pump at the required output of 16 bar, or they could manage a sufficient flow rate at 600ml but were not designed for the necessary discharge pressure. l
