POLSTEAM prepares for changeover with the Alfa Laval ACS

Image
  POLSTEAM’s fleet includes 60 bulk carriers that handle t he majority of its business. Based in Poland and travelling frequently to destinations in  the US and Canada, the vessels spend time in both European and North American ECAs. POLSTEAM was, therefore, eager to ensure safe fuel changeover when ECA sulfur limits t ightened. Well-controlled cooling is a must Early on, POLSTEAM recognized the potential hazards of switching between HFO and MGO/MDO. These include impaired maneuverability at the start and low load, as well as pump seizure and temperature shocks in fuel line equipment. To avoid these problems, POLSTEAM chose the advanced automation and integrated cooling of the Alfa Laval Automated Fuel Changeover System (ACS). “We began looking at the ACS concept some time ago, given that we are involved in both US and ECA operation,” says Leszek Trachimowicz, POLSTEAM Technical Director. “What became clear very quickly was that more than the fuel switch itself is important.

Bulker-fit configuration for Alfa Laval PureBallast 3 matches differentiated ballasting/deballasting flows

  Bulk carriers can now benefit from an Alfa Laval PureBallast 3 bulker-fit configuration, which is specifically adapted to their flow needs. The bulker-fit configuration offers savings in footprint, installation, OPEX, and especially CAPEX, yet it retains the high performance, easy operation, and global service coverage PureBallast 3 is known for. A growing number of ship owners are choosing UV ballast water treatment over electrochlorination, even for large ballast water flows. Today’s UV treatment competes easily on footprint and energy consumption, which makes advantages like chemical-free operation, zero corrosion risk, and efficiency at low salinities and temperatures even more attractive. Until now, however, the move towards UV has been less noticeable among bulkers. “Bulkers have a unique ballasting and deballasting profile because they load and unload at significantly different rates,” says Peter Sahlén, Head of Alfa Laval PureBallast. “The PureBallast 3 bulker-fit configurati

Alfa Laval Compabloc Compact Heat Exchanger Range

Image
Alfa Laval Compabloc range is compact and designed for optimum performance and serviceability across a broad spectrum of industrial process applications. Standard pressure range up to 42 bar. Application The Alfa Laval Compabloc is a fully welded compact heat exchanger designed for the complete range of process and utility duties. The Compabloc range provides the most efficient, cost-effective, compact and cleanable heat exchanger solution available today. After 20 years on the market, Compabloc has shown itself to be the market leader in terms of life-cycle costs and energy savings. Design Alfa Laval designed the Compabloc range of welded heat exchangers with a focus on performance, compactness, and serviceability. The heart of the Compabloc is a stack of corrugated heat transfer plates in 316L stainless steel, or other high-grade material. The plates are laser welded (models CP30 and above) and form a compact core. This core is then enclosed and supported by four corner g

The spiral heat exchanger solves a difficult fouling problem

Image
One of the great features of the Spiral heat exchanger is its ability to handle media containing suspended solids without clogging. Mitteldeutsche Erdoel-Raffinerie GmbH (MIDER) in Leuna, Germany took advantage of this feature when they replaced their existing bottoms product coolers in the fluid catalytic cracking (FCC) unit with spiral plate heat exchanger , and in this way drastically reduced the down-time and maintenance cost. MIDER’s Leuna-refinery is a totally new grass-roots facility replacing an older refinery that was located on the same site. The new refinery which is owned by Totalfina Elf, started up in 1997. Originally the installation included two double-pipe exchangers in carbon steel - one in operation and one as stand-by - to cool the bottoms product from the main fractionation column.   Reduced down-time and maintenance costs Only two weeks after start up of the FCC unit the double-pipe exchanger plugged up on the product side and had to take out of operation

3 strategic advantages of the Alfa Laval welded plates heat exchanger

Image
Choosing equipment to transfer the fluid heat in production processes are vital for the performance and efficiency of our customers. Our strong alliance with Alfa Laval guarantees not only prime quality heat exchangers, but also the support of the leading manufacturer. Apart from the brand’s worldwide recognition, we advocate for what the benefit of choosing an Alfa Laval heat exchanger means to our customers.   What is a heat exchanger used for? This equipment is gaining a field in the refrigeration industry thanks to its versatility and efficiency. Even though industrial applications are very diverse, the solutions it offers are pretty concrete: ·          Transfers temperature from one fluid to another, heating a cold fluid through a higher temperature fluid. ·          Reduces a fluid’s temperature through a lower temperature one, helping cool the fluids involved in the productive chain. ·          It allows fluid to reach its boiling point. ·          It allows con
