Oseco offers a full-range of pressure relief solutions for the chemical, refining, offshore oil and gas, bio-tech, and food industries.

Featured Case Study

The Oseco capital projects team was approached by a major polyethylene producer in North America in the Spring of 2016. The company had recently built a new polyethylene unit, and was experiencing premature failures of a competitor's rupture discs in a very critical application.

Safety Relief Valve Isolation

Rupture discs are often used to isolate the inlet of safety relief valves to protect the valve internals from corrosive processes. ASME Section VIII recognizes the use of rupture discs under Paragraph UG-127.

Process Vessels

Any process vessels subject to over pressurization are candidates for rupture disc solutions.

Chemical Reactors

Reactors are designed to contain chemical reactions. They may be exothermic or endothermic and can be batch reactors, continuously stirred tank reactors or fluidized bed reactors among others.

Process Columns

Process towers or columns are used in the distillation process. Distillation towers or distillation columns are designed to operate to produce varying streams according to the output streams boiling point.

Chemical Chillers

Vapor compression chiller technology uses four basic types of compressors - reciprocating, screw driven, scroll and centrifugal. All mechanical machines where over-pressure protection may be necessary.

Chemical Heat Exchangers

Heat transfer from one medium to another is widely used in chemical plants, petrochemical plants, petroleum refineries, gas processing and power plants and often require specialized over-pressure protection.

Industrial Gas Storage & Transport

Liquid nitrogen trailers typically employ the use of rupture discs in concert with safety relief valves should the safety relief valve fail to operate successfully. Many other industrial gas transports are often fitted with rupture discs to prevent catastrophic events.

Refining Distillation Columns

Industrial distillation is the most common form of separation technology used in chemical, petro-chemical, refineries, natural gas processing and cryogenic air separation plants. Rupture discs are commonly used as over-pressure protection devices.

Refining Separators

A solid safety feature for oil and gas separators includes the installation of a rupture disc and holder. The disc is typically used in conjunction with a safety relief valve as a secondary device to relieve pressure from 1.1 – 1.21 times the MAWP of the vessel.

Refining Coking Drums

Cokers or delayed cokers process residual oil stocks by heating it to its thermal cracking temperature in a furnace operation with multiple passes. Due to the number of pumps, separators, and condensers at high temperatures, rupture discs are often employed as a means of over-pressure protection.

Dehydrator Rupture Discs

Rupture discs are generally used as secondary relief devices on dehydrators. The rupture disc's set pressure is higher than the safety relief valve. If the relief valve cannot handle the upset in the dehydrator, the rupture disc activates to relieve the upset. Oseco also manufactures burst sensors that can be simply hooked in with the dehydrator's automation. In the event of an overpressure, the burst sensor can shut down the dehydrator saving environmental damage.
