Simon stores refrigerant gas for BOC

Simon Storage BOC Tanks

Simon Storage Ltd (“Simon”) has won a prestigious contract to supply specialist gas storage and handling facilities at its Seal Sands Terminal (“the Terminal”) on Teesside, England, for BOC, the UK’s leading provider of industrial gases. Two liquefied gas storage vessels at the Terminal have been customised to store special gas formulations for subsequent delivery to key BOC customers. Each tank has a storage capacity of 317 tonnes and is provided with dedicated piping systems for road vehicle loading and off loading, vessel recirculation and product sampling.

Modifications have been overseen by Simon’s in-house Project Engineering team to meet the specific requirements of these special gas formulations as well as the Pressure Systems and Transportable Gas Containers Regulations 1989. These include rating the vessels to a maximum design pressure of 16.3 bar at 45oC, and fitting instrumentation to detect excess high or low pressures and temperatures within the vapour space. The vessels are also equipped with a level measurement gauge giving local read-out at the road tanker loading/off loading point and on the tank gauging computer in the control room.

In line with operating and safety standards for bulk liquid and gas storage facilities, Simon is providing containment of approximately 400m3 around the vessel storage area, together with a fixed deluge system to the vessels for cooling purposes in the event of high product temperature. The information technology infrastructure at the Seal Sands Terminal will enable communication of tank fill level, temperature and pressure to the Terminal’s computerised systems for monitoring purposes and activation of alarms and deluge systems.

Simon has also commissioned an independent road loading system to serve the BOC contract, comprising a line from each storage vessel that feeds a road loading point, and a vapour return line from the gas road loading area. The loading process utilises a metering system as a guide to quantity, and delivered weight is confirmed by an approved weighbridge. In addition, dedicated 3-inch carbon steel lines, with anti-static and fire certified valves, have been installed on each tank to allow receipt of product into storage from road tankers.

Martyn Lyons, Simon’s Managing Director, said “We are delighted to be able to offer our expertise in gas storage to BOC, and to extend our long standing relationship with BOC at our Immingham Terminals to this bespoke facility at Seal Sands.” Simon has extensive expertise in gas handling and storage, including pressure liquefied gas storage for pharmaceutical grade products, as well as industrial process gases such as butane and propylene. A portfolio of facilities designed and constructed to relevant international standards is available for short and long term contracts as required.
