​Refinery tight lipped following burn-off concerns

Published

on

VALERO has refused to explain why their flare stacks at the Pembroke Oil Refinery were worryingly large on Friday night (Nov 16).

The Pembrokeshire Herald received several messages and photographs of the unprecedented burn-off from readers and concerned locals via social media and email.

An unconfirmed source at the refinery told this newspaper that there had been a problem with the alkylation de-isobutanizer – it ‘fell over’ our source said.

Alkylation is the process of producing gasoline range material such as propylene and butylene with isobutene – in the presence of a highly acidic catalyst, either sulphuric acid or hydrofluoric acid.

When asked to confirm the emergency burn off took place, and when asked if there was a serious malfunction, Stephen Thornton, Public Affairs Manager told us: “It is company policy not to comment on operations.”

When asked if he could deny that the incident occurred he again declined to comment.

A refinery expert told us: “The towers which have a constant burning flame is called a flare stack. In very simple terms, it is just like the burner of a gas stove with a controlled burning of natural gas through its pilot burners. It is the last line of safety or defence for refineries, petrochemical and gas processing plants.”

The expert went on: “The flare system consists of the flare stack and a flare header. A very large network of pipes coming from the different processes feed into the header. Whenever there is an upset or an emergency situation, all the extremely flammable hydrocarbons need to be vented out.

“But these cannot be just put in the atmosphere like the steam from our food pressure cookers. A vapour cloud would be extremely hazardous and catastrophic. To ensure that these escaping gases get burned to Carbon dioxide and water vapour, a flame is always kept burning on the top.

“Refinery operators generally see this as a necessary evil.

“The location of a fire stack is also very important. It is located far away from the main processing complex in the downwind direction.”

In April this newspaper reported that a potentially ‘catastrophic incident’ took place at Valero’s Pembroke Oil Refinery last year involving leaking gas and an ignition source

As previously reported, we were contacted earlier this year by a number of workers at the site who told us that it is only ’pure luck’ which prevented leaking gases from being blown into an ignition source, believed to be a furnace, which could have led to another lethal incident at the plant.

Valero have confirmed that they are working with statutory authorities who are investigating the event, which occurred on November 30 last year. It involved the Alkylate Iso-Stripper, which creates Alkylate – a premium component of petrol that has exceptional anti-knock properties and is clean burning.

The oil refinery’s management told us at the time that it is working with ‘continued co-operation’ with regulators, and highlighted in a statement that ‘no personnel were injured’ and that ‘there was no impact on the community’.
Valero, which says it is one of the leading employers in south Wales, added that they are unable to comment further during the period of investigation.

A Health & Safety Executive spokesperson told The Herald in a prepared statement: “We are aware of an incident at the Valero Energy Limited Pembroke Refinery in November 2017 which was reported to the Health and Safety Executive under RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013).
“We can confirm that the incident took place on the Alkylate Iso-Stripper, and is being investigated.
“No enforcement action has been taken, though the investigation remains on-going.”

Rugby Weekly – Tenby’s promotion push continues

Published

on

It’s crunch time for all rugby clubs around the county, whether promotion is their aim or fighting relegation or even just trying to improve their league position, it’s now or never. 

Last weekend saw an important win for Fishguard in division two west which should put any relegation fears to bed completely. James Griffiths added an impressive 18 points for the Seagulls as they defeated Nantgaredig 33-19. 

Elsewhere in the second division, Milford were beaten 32-8 by a good Lampeter outfit. The Mariners are still a little too close for comfort with the drop zone but should have enough quality to see them safe. 

At the other end of the table Tenby sit in second place and have played fewer games than leaders St Clears and third place Lampeter. They won impressively again last weekend, beating Pontyberem 64-19 at Haywood Lane. Fletcher Broadhurst impressed with two tries as did Hywel Baker who also grabbed himself a brace. Another excellent performance in an outstanding season so far in which promotion would be the absolute icing on the cake. 

In Division Three West, Pembroke were well beaten by Laugharne 74-15 in which the outstanding Liam Price and Nico Setaro both crossed the whitewash 4 teams a piece. The latter also added 7 successful conversions. 

There was a local derby at Pill Parks where Llangwm hosted Pembroke Dock Quins and it was an exciting clash. The visitors won narrowly 28-23, Craig Barnett and Gethin Bradney both scored two tries for the Quins. The Wasps battled hard and will be proud of their performance, Gethin Thomas impressed for the hosts with two tries of his own but it wasn’t enough to secure the points. 

St David’s hosted the high flying Cardigan outfit and were unable to score in reply to the visitors 20 points, with it ending 20-0. The Saints however won’t be losing too much sleep over it as they have had a great season so far.

Stephen Crabb leads inquiry on retaining community bank services  

Published

on

PRESELI Pembrokeshire MP, and Chair of the Welsh Affairs Select Committee Stephen Crabb is leading an inquiry in Parliament that will investigate the closure of high street banks in Wales, as well as access to cash.

In November 2023, Pembrokeshire saw the closure of Lloyds Bank in St Davids, and in the coming months both Barclays Bank and Halifax in Haverfordwest are set to close. In recent years, Wales has experienced a rapid decline in the number of high street banking services available to the public. Already in 2024, 23 high street bank closures have been announced in Wales, while automated teller machines (ATMs) declined by nearly a quarter between 2018 and 2023.

The Committee willconsider how declining high street banking services are impacting vulnerable people and small businesses across Wales, who are often more reliant on cash than digital banking. It will also examine how Wales is being affected by the loss of high street bank services, and whether the problem is worse in Wales than other parts of the UK.

Mr Crabb is a staunch advocate for retaining community banking facilities, especially in rural communities like Pembrokeshire where many local branches remain the only source of face-to-face banking provision for miles.

Recently Mr Crabb challenged Barclays Bank senior management on their decision to close the bank branch in Haverfordwest– a move that will see Barclays not only pull out of the county town, but means they won’t have a branch left anywhere in Pembrokeshire. He has also engaged with LINK – the UK’s largest cash machine network – and continues to campaign on the basis that a Banking Hub is established and that ATM machines should be retained or installed, especially in areas worst affected by the closures.  

Following the launch of the inquiry, MP Crabb added: “It is really sad to see so many banks across Wales closing as online banking grows in popularity. Despite the advantages of online banking, for a rural community with an ageing population like Pembrokeshire, bank branches hold huge importance as they offer face-to-face customer service.”

“I am acutely aware of the inconvenience that the bank closures locally have already caused following hundreds of replies from constituents to my ‘online banking survey’ ”

“I am looking forward to gathering further evidence on this subject through the committee’s inquiry, and will continue to put pressure on the relevant stakeholders to ensure that adequate alternative provisions are made through the establishment of banking hubs as well as the instalment of ATM machines where necessary.”

“In this inquiry, we are particularly keen to hear from those likely to be directly affected by the shift away from cash and physical banks. I encourage anyone with first-hand experience of losing banking services to give evidence to the Committee”

Trains resume between Carmarthen and Pembroke Dock as works end

Published

on

TRAIN services resumed this morning (Thursday 28 March) after ten days of essential round-the-clock work to upgrade track and drainage between Carmarthen and Pembroke Dock.

The railway was closed from Monday 18 March to Wednesday 27 March to allow Network Rail teams to replace more than 200 metres of track and 300 tonnes of ballast (track stones) between Pembroke station and Pembroke Dock.

Work to improve the drainage between Narbeth and Kilgetty stations was also completed at the same time.

Nick Millington, Network Rail Wales and Borders route director, said: “This essential work in Pembrokeshire demonstrates our commitment to improving the reliability of the service we provide to passengers along our route.

“We know that replacing the track can be disruptive and very noisy, so I would like to thank the residents of Pembroke for their patience while our team carried out this crucial work.”

Colin Lea, Planning and Performance Director at Transport for Wales said: “We’re pleased that our colleagues in Network Rail have completed this essential work and that Transport for Wales rail services resumed today.

“We’d like to thank passengers for their patience while this work has progressed and look forward to welcoming passengers back in time for the Easter weekend.”
