Desalination project UAE - ADNOC Refining

Desalination project UAE - ADNOC Refining has awarded a $473 million contract in 2018 to Samsung Engineering to deliver a new power & water generation plant for the Abu Dhabi oil giant.

The Waste Heat Recovery Project (WHRP) will be constructed at the Ruwais Industrial Complex, 240km west of Abu Dhabi city UAE.

Krone has produced the main filters as crucial part of this important ADNOC project an undersigns Krone Position in desalination projects in the region following the filter delivery to Saudi Aramco Ras Tanura desalination project delivered in 2019.

Successful final inspection was held on 5th May 2020 for 4 units seawater backflush filters ANSI 28” class 300 for ADNOC Ruwais refinery WHR Project with a capacity over 5000 m3/h each filter unit at 1 mm filter mesh are produced with special internal rubberlining for corrosion protection with additional super duplex and titanium internals.

ADNOC Refining Waste Heat Recovery Project has a Capacity to desalinate seawater and produces drinking water in a permanent high capacity. The Krone completely redundant filter system will protect the desalination process and filter the raw seawater INTAKE.

This Waste Heat Recovery Project (WHR) follows the EPC contract signed with SECL in July 2018 for the Crude Flexibility Project (CFP). The final destination of the plant is UAE for the Ruwais Refinery owned by Abu Dhabi National Oil Company (ADNOC).

The scope of supply includes engineering, fabrication and delivery of two Multiple Effect Distillation with vapour thercompression units with a capacity of 31 250 m3/d each.

Saudi Aramco Ras Tanura Refinery Clean Fuel Project

Krone has delivered 12 filters for Saudi Aramco Ras Tanura Refinery Clean Fuel Project – desalination plant – with MED desalination technology.

Krone has been awarded to produce 12 self cleaning filter for contract signed by Tecnicas Reunidas Madrid with SAUDI ARAMCO. Krone has supplied to the contractor filters for a desalination plant for filtration of RAW seawater.

The scope of supply included the engineering, fabrication and delivery of 12 filters for the three Multiple Effect Distillation with thermal vapour compression units TVC. The desalination technology used is Multiple Effect Distillation (MED-TVC).

A Multi Effect Desalination MED unit is an evaporator where sea water is evaporated in one or more ( up to 14 ) evaporation stages at low temperature (< 70°C ) in order to produce clean distillate water.

MED process is designed to produce distilled water with steam or waste heat from power production or chemical processes, and/or to produce potable water. Krone filter KAF reliable self cleaning filter system supports the functionality of the plant in this crucial job.

Instead of Christmas Gifts: Krone donates to SeaShepherd

Krone donates to SeaShepherd please join us – stop killing Cetaceans in EUand worldwide

Demanding Legal Accountability for the Slaughter of Cetaceans in the Faroe Islands

In cooperation with Sea Shepherd Global and Sea Shepherd Netherlands, Sea Shepherd Legal is tirelessly working to stop Denmark’s ongoing facilitation of the Faroese "grindadráps."

During the grindadráps, the Faroese drive hundreds of pilot whales and other cetaceans into killing bays, drag them closer to shore with crude hooks, and then slice open their spinal cords, staining the waters a sickening crimson. Although EU law does not directly apply to the Faroe Islands, it most certainly applies to Denmark – and Denmark has blood on its hands. The evidence conclusively proves that Danish officials, including police, navy, and customs officers, have been facilitating and supporting the slaughter of cetaceans in the Faroe Islands. By actively assisting the Faroe Islands in this slaughter, Denmark violates its duties under the EU Habitats Directive. The Habitats Directive prohibits member states (including Denmark) from all forms of deliberate disturbance, capture, or killing of cetaceans.

10 year anniversary of SWRO KAUST delivery for the Enduser Aramco / King Abdullah University of Science and Technology

10 year anniversary in 2017 since the delivery of 3 Krone Bernoulli units 24” KAF. The King Abdullah University of Science and Technology (KAUST) in Thuwal, north of Jeddah in Saudi Arabia, required a desalination RO based technology plant for the university buildings and its accommodation. The plant was designed with a capacity of 40,000m3/day with the facility to increase to 50,000m3/day in the future, as and when required.

The huge advantage of Krone KAF self cleaning auto Bernoulli filters was that they can work without pumps in front – just with the water column pressure of the red sea level! Only 0.2 bar is sufficient to run the KAF filters in fully automatic mode.

Operationally, water is abstracted by pipeline form the Red Sea and filtered by 3 KAF 24” Krone Filter Solutions Bernoulli filter units and then pumped through 4 Superflux filters, prior to being processed through cartridge filters and the four Sea Water Reverse Osmosis (SWRO) units. Energy recovery is achieved using Pelton turbines thus reducing the energy consumption of the Reverse Osmosis (RO) plant. The treated water from the first stage is used as potable water for the university and irrigation water on the site. A further second pass Brackish Reverse Osmosis (BRO) system is included to produce water for the central utility cooling system.
