Where crude oil is processed and refined, Howden supply safe and reliable equipment
Howden equipment operates safely across a wide range of applications within the refining industry. Howden supply various compressor and fan technologies, ranging from site utilities to the large critical process applications and from bare shaft to fully packaged equipment.
Typical compressor roles are make up, recycle, hydrogen feed (HGU, HDT, HDS), gas recovery and process reactors blanketing. Howden compression solutions integrate site infrastructure utilities such as nitrogen and air networks, instrument air, waste water treatment, flare gas recovery (FGRU), air for gas incineration, fuel gas turbine feed and inlet air cooling for power generation.
Howden fans extract residual gases from process capacities, ensure building ventilation and aeration, combustion air and room pressurization. Our fans are selected to ensure reliable ventilation in crisis situations.
Howden owns a set of fluid handling technologies covering ventilation, compression and heat transfer. Howden brought solutions to many specific challenge met in refinery sites and processes.
Every site project has different specific needs and operating conditions. Our ability to deliver custom-design solutions that meet API codes is extremely valuable. Whether supplied as a stand-alone unit or a complete package, our equipment is designed to match the rigors of its environment as well as its specific task, and is engineered to offer continuous uninterrupted operations.
Howden engineering teams and field engineers have access to our 160 years of knowledge, meaning we can offer our expertise at every step of the process from product selection to ongoing support. Our worldwide organisation provides local responsive support to end users and customers.
The blower provides combustion air into the furnace to generate heat, against a typical back pressure of 0.8 Bar.
Dewaxing is a process used in the production of lube oil and carried out using a solvent based or catalytic method. Catalytic dewaxing involves cracking of n-paraffins and compressed hydrogen is used to prevent coking. Howden deliver compressors packages with API & ATEX design & construction.
Dewaxing is a process used in the production of lube oil and carried out using a solvent based or catalytic method. Solvent dewaxing involves the refrigeration of lube stock and solvent as it passes through tubes that have a rotating scraper. A mechanical refrigeration system will require compressors. Compressors are used to process the refrigerant(Propane/ Propylene) or in a catalytic system to recycle hydrogen.
Reactor catalysts deteriorate over time and are regenerated by use of circulating gas via a regeneration gas compressor (also termed recycle). Hydrogen is a by-product of the reforming process and is compressed after the separator for recovery by a net/rich gas compressor.
Overhead vapors from the drums flow to a fractionator (combination tower) which separates out gases, gasoline, diesel, heavy coker gas oil and recycles them. Pressure is controlled by a wet gas compressor processing the overhead gases from the tower.
CC Fluid Catalytic Cracking for Heavy and residue treatments. Vapours or wet gases from the reactor main column overhead are passed to the vapor recovery unit within the FCC where they are compressed by the Wet Gas Compressor (WGC) before being transferred to the high-pressure condenser/ receiver within the refinery gas concentration unit/ plant.
Howden supplies reciprocating compressors packages with API & ATEX design & construction
VDU Vacuum Distillation Unit. Residues from the CDU are heated in a vacuum furnace and then flashed in a VDU column with products being drawn from the column at the top, side and bottom for further processing. The gas (overhead vapors) existing the tower at the top passes to a vacuum system. The vacuum system has an overhead accumulator which separates liquid and vapors. The vapors may be compressed by a compressor or booster blowers.
Delivery of pressurised nitrogen for site process needs. Dry compression ensure gas purity preservation. Howden supplies compressor packages with design & construction matching area protection levels specified by the site.
At emergency evacuation points, axial and centrifugal provide reliable ventilation in crisis situations.

Onsite power is often generated using gas turbines. Modern turbines have increasing high pressure feed gas requirements designed to optimize power output. As available gas pressure is commonly lower than required it is boosted through a compressor prior to the turbine combustion chamber.
Treating contaminants such are petroleum hydrocarbons, ammonia, and organic sulfur. For mechanical system or diffused aeration system, air supply is needed into the diffuser. Howden supplies air blowers for the application.
At emergency evacuation points, axial and centrifugal provide reliable ventilation in crisis situations. Living quarters overpressure to protect rooms and staircases from hazardous fumes.
Various units within the refinery system will emit vapors which will be routed to the blowdown system/ Fuel Gas Recovery Unit. The gas is separated out from any remaining hydrocarbons and is compressed to the fuel gas system.

During storage, light hydrocarbons dissolved in the crude oil or condensate vaporize. Compression systems are used to recover the vented gas and reduce venting to atmosphere or flaring.
General furnace applications for combustion of waste gas.
Process H2 compressors.
Our lifelong aftercare service will supply original replacement parts, support you with maintenance and installation, and even train your own engineers in maintenance techniques. We keep detailed plant records almost indefinitely, and regularly supply spare parts for machinery over 50 years old.
