A specially adapted oil separator is enabling effluent from a train underframe washing to be discharged to a dram, waste oil to be collected and the water potentially to be recycled. Hodge Stetfield Ltd has recently built a three stage Stetpak oil separator unit for the new train maintenance facility at BR Birmingham, UK At present, effluent is discharged to a foul drain, but current trials have indicated that the water quality may be suitable for re-use via the inbuilt recycle option. The first stage in the unit has the separation plates set further apart than normal, to remove the solids content. The second stage is primary oil separation, using another plate pack but with closer spacing. The final stage is a
porous media coalescer, to remove the more freely dispersed oil. Wastewater is pumped from the collection point near the train wash to the Stetpak located 200 metres away, and after treatment is gravity discharged to drain. When the Stepak recycle facility is used, treated water will be pumped directly back to the feed tanks on the high pressure was plant. Surface oil is pumped out of the Stetpak’s separator section and decanted into an integral oil chamber, from which it is pumped into a storage tank for collection by a waste oil tanker.

Major contract for new filtration process Alan-Cobham Engineering has been awarded a multi-million pound contract by the AkerKellogg Joint Venture, as main contractor for the Troll Phase 1 processing plant outside. Bergen, Norway. A/S Norske Shell is the development operator for Troll Phase 1. The contract is for two filtration systems for the onshore gas receiving station for the Troll Gas Field. The 50 ton skid packages filter the hydrocarbon condensate and aqueous fluid from the pipelines. These contain, on a yearly basis, a significant level of solids contamination, which are beyond the capacity of conventional filtration. To prove the technology, the
complete skids will be tested in Cobham’s fuel test laboratory within their works. Rather than using liquefied natural gas which requires very high pressures and special safety precautions, aviation fuel will be used. This has similar properties at low pressure and the facility has storage for over 33 000 gallons. Both solid and liquid contaminants can be added to provide a simulation of the incoming process stream and the level of particulates and water in the outlet can be measured precisely.

Memcor to supply second microfiltration plant to Bulmer Memcor Ltd is to install a continuous microfiltration (CMF) plant at the H.P. Bulmer Ltd cider mills in Hereford; the second order worth over &SOO,OOO. HP Bulmer has an on-going development project to modemise its Hereford site through the implementation of the latest technological advances in cider making processes with the overall aim of lowering production costs. As part of this programme, the Memcor CMF plant will replace several stages of labour intensive filtration used in removing yeasts, proteins and other solids from fermented cider beDecember
fore blending and packaging. Employing membrane technology, the plant will be able to filter up to 240 m3/day of cider to an 0.2 micron specification. The Memcor CMF plant will be configured to contain two identical Microblock process units, each with a membrane surface area of 12mz. The units will be provided with faciltities for an automatic clean-in-place (CIP) system for the membrane blocks and associated pipe work. Mem~or Ltd, Derby Road, Wiksworth, Derbyshire DE4 4EP, UK.
