About Axsia Howmar

Axsia Howmar is a UK engineering consulting and contracting company working in crude oil treatment and hydrogen purification. We design and manufacture process packages: approved and audited fabricators build them under our project management and supervision. We deliver, commission and hand over. We also review and troubleshoot existing units and supply spare parts, including for equipment built by others.

What we do

Four things, for two kinds of plant

  • Design and manufacture

    Process packages for crude oil treatment and hydrogen purification, from a datasheet to a complete package. We own the design and the specification.

  • Project-manage and supervise

    Approved and audited fabricators build to our drawings under our supervision, inspection and test plan.

  • Commission and hand over

    Site commissioning, start-up support, operator training and, where specified, a performance test run.

  • Review, troubleshoot, supply spares

    Design reviews, diagnostics and spare parts for existing units, including equipment built by others.

Experience

Engineers who have designed, commissioned and supported this equipment

Our engineers have designed and commissioned indirect fired heaters, electrostatic dehydrators and desalters, kerosene prewash coalescers and hydrogen PSA and TSA units for oilfields and refineries in the Middle East, Europe and elsewhere, and have supported those units in operation with troubleshooting, retrofit internals and spare parts.

That experience is what lets us identify a legacy unit from a nameplate, and design a package that can be built, operated and maintained without surprises.

How we deliver

We design and manufacture; approved fabricators build to our design

Axsia Howmar owns the design and the specification of every package. Fabrication is subcontracted to fabricators that we, or the client, have approved and audited: from the client's approved vendor list, or from the fabricators our own team has audited. We project-manage and supervise the build, inspection and testing, then deliver, commission and hand over.

This keeps the engineering in one place and lets fabrication happen close to the site or in the client's preferred workshop, without the client having to manage the interface.

What we do

In crude oil treatment we cover the train that takes produced crude to export or refinery specification: production separators, indirect fired heaters, and electrostatic coalescers in dehydrator and desalter duty. We also design electrostatic prewash coalescer packages for kerosene treating units. In hydrogen we design pressure swing adsorption (PSA) packages for reformer and refinery hydrogen, and temperature swing adsorption (TSA) packages for gas dehydration and for purifying electrolyser hydrogen in DeOxo dryer packages.

How we deliver

We work from a client datasheet or specification through process design, detailed design, procurement, manufacture, inspection, delivery, commissioning and handover, as a single turnkey scope or as any part of it. We design and manufacture without owning a fabrication workshop. We own the design and the specification, subcontract fabrication to approved and audited fabricators chosen from the client’s approved vendor list or from our own network, and project-manage and supervise the build under our inspection and test plans. This keeps the choice of workshop open to the client and suited to the project location.

Experience

Axsia Howmar’s engineers have several decades of experience designing and supplying process packages to oilfields and refineries in the Middle East and other regions. Project references are shared in a form that protects client confidentiality; see projects. We do not publish client names, plant data or equipment records.

Standards

Design codes are agreed for each project. Codes typically applied include ASME Boiler and Pressure Vessel Code Section VIII, the Pressure Equipment Directive 2014/68/EU and UK Pressure Equipment (Safety) Regulations, API standards for fired heaters and vessels, and IEC 60079 and ATEX or UKEX requirements for electrical equipment in hazardous areas. The applicable list is confirmed per project. See certifications and quality.
