Compressors serve processes such as LDPE, LLDPE, HDPE, PP, PTA, VCM. Typical roles are make up, recycle, Hydrogen feed, gas recovery, blanketing, utilities, conveyors, instrument and combustion air. Howden fans extract residual gases from process capacities, ensure building ventilation and aeration and room pressurization. Howden fans are consistently selected to ensure reliable ventilation in crisis situations.
Important differences across projects, such as gas composition, process license and site requirements, make our ability to deliver custom-design solutions valuable.
Our equipment delivers long-term heavy duty use. Howden‘s custom approach, based on a thorough analysis of all the factors involved provides a proven route to the right equipment for each unique set of circumstances.
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.
Un-reacted VCM from the polymerization reactor is pumped from the reactor and passed through a compressor prior to a condenser used to recover VCM
H2 gas compressor
Recycle compressor packages API & ATEX for the application.
Move bulk materials that are suspended in an air stream that is introduced by a positive pressure blower PD blowers in additive addition and pelletizing.
H2 recycle compressors.
Unreacted gas recycling compressor.
Phenol production via cumene involves oxidising cumene with air to form hydroperoxide which in then mixed with sulphuric acid to produce phenol. Blowers provide the oxidition air.
Within the acrylonitrile production process off gas from the absorbers can be recovered via a compressor.
HCN (hydrogen cyanide) is a by-product of acrylonitrile production and is passed through a condensing system which requires refrigeration and refrigerant compressors.
PO purification systems can incorporate a vacuum stripper using compressors.
Cracked C4 streams are quenched and compressed prior to scrubbing, dehydration and distillation. Degassing within the distillation section can also include compression of overheads for recycling.
Process H2 compressor
Liquid product transfer to rail or truck mounted tanks. Compressed gas push liquids
Compressors deliver high pressure hydrogen into the hydrogenation reactor. Diaphragm compressor insulated compression chamber ensures H2 purity preservation.
Vent compressor to recover and liquefy harmful gases instead of being vented.
N2 gas supply for process blanketing with inert gas.
Within xylene isomerization, the isomerate is distilled in a deheptanizer from which hydrogen is recycled through a compressor to the process.
Delivery of pressurised nitrogen for site process needs. Dry compression ensure gas purity preservation.
At emergency evacuation points, axial and centrifugal fans provide reliable ventilation in crisis situations. Living quarters overpressure to protect rooms and staircases from hazardous fumes.
Dry compression solutions.
Onsite power is often generated using gas turbines. Modern turbines have increasing high pressure feed gas requirements designed to optimise 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.
Low noise, high efficiency fans for cooling towers.
Off gas streams recovery. Recover off gas streams that are to be flared. Mainly by compression of corrosive gases. Compression solutions are delivered with compatible materials and protection level according area classification.
Fans for contaminated gas incinerators, thermal oxidizers, aeration, cooling towers and living quarters overpressure preventing rooms and staircases from hazardous fumes contamination, keeping safe environments free from the risk of explosive and hazardous gases.
Large ASU Oxygen and air compressor.
Tank boil-off gas vapors will be recompressed and recovered to storage via a reliquefaction system or potentially supplied to the plant for other processes.
Ethylene is passed through the primary reciprocal compressor
Resin leaves the reactor into a discharging system where unreacted materials are separated from resin then compressed via a vent recovery compressor before being cooled and re-entering the loop.
HDPE-LLDPE Linear Low Density Polyethylene. Ethylene make up compressor package API & ATEX
HDPE-LLDPE Linear Low Density Polyethylene. N2 Service compressor for polymerization process.
Ethylene Oxide-Ethylene Glycol (EO-EG). Ethylene gas make-up compressor for reactor feed.
HCI that is vented from the oxy-chlorination reactor can be sent through a refrigerated condenser for recovery. Process requires refrigerant compressors.
