Prism Detonation Arrestor

A choice for every configuration.

The Prism End of Line Detonation and Standard Flame Arrestors group can be arranged in many different configurations. We can configure these units using USCG accepted Detonation Flame arrestors, CSA witnessed Detonation Flame arrestors, Deflagration Flame arrestors or high-grade flare stack flame arrestors.

Prism Product Features

Prism Integrated Solutions Inc. can assemble a variety of products upon your request. These sizes range from 2” to 12”, and come in CS, 304 S.S., 316 S.S., Hastaloy, etc. Flow curves and gas classifications are available upon request.

Mounted on the inlet of the flare stack or thermal oxidizer, the detonation arrestor stops the propagation of flame from continuing through the flare system towards the process equipment.

INDUSTRY LEADING

PATENTED INNOVATION

Prism Flame Stabilization Protection

As Our unequaled design enables our units to achieve a Type 1 USCG burn rating and a Type 2 burn rating for CSA Z343-98, giving the product the best burn rating on the market. Prism Integrated Solutions Inc. has spent countless hours, effort and dollars in research, testing, and redesigning of our burner management systems to achieve this burn rating. We wanted to afford our customer with a greater length of time to react and correct a potentially dangerous condition in the event of a stabilized burn situation, with the Detonation Arrestor being a passive device which will withstand and react to all given situations equally. No other manufacturer can parallel this burn rating.

ITS
FEATURES

100% stoppage of detonations exceeding pressures of 1800 psi and speeds of 7000 fps
100% stoppage of low, medium and high-pressure deflagrations, overdriven and stable detonations
Will withstand severe flame stabilizations without causing cell or housing breakdown
Minimal cell back pressure, due to the open cell area (flow curve chart available)
Our Alumina Ceramic media also help prevent sparks from travelling through the media – unlike crimped ribbon designs that have straight through passages
Spreader bolts for quick, easy maintenance when required
Cells can be rebuilt; they are not a throw away item
Offset inlet and outlet on OSSF & OSDF models prevent fluid build-up (allowing fluid to pass through the unit)
Carbon or stainless-steel housing with stainless-steel cage and Alumina Ceramic media (for extended life) eliminates breaking or melting that can occur with aluminum products
USCG Accepted
Tested to CSA Z343-96

Compliance.

Prism Integrated Solutions Inc. affords the maximum safety window for personnel to react to the flare system situation or for the situation to change and go away. Prism Integrated Solutions Inc. has invested countless hours and funds to develop the continuous burn protection that we offer in our detonation flame arrestors.

These units have USCG acceptance and CSA verification of performance. These approvals assure that your products will be protected from fire and explosion.

In-Line Single Flange-B

AVAILABLE SIZES: 8’’
Prism’s ILSF-B SS detonation flare stack flame arrestor incorporates all the working features of the ILSF-A detonation flame arrestor, but the flame quenching element does not have a machined gasket face on it. Spiral wound gaskets cannot be used. The ILSF-B uses sheet gaskets that are compressed between 2 machined surfaces. This sealing system on the quenching element is the most used flare system in the oil and gas industry where economics are key in purchase decisions. The gasket arrangement meets all code requirements and are easy to manufacture. The compression seal is more than adequate for low pressure lines that are carrying volatile vapors.

In-Line No Flange (ILNF)

AVAILABLE SIZES: 8’’

The ILNF offers all the working characteristics of the ILSF-A and B but does not have a removable flame quenching element. The flame quenching element is instead welded into the unit. The INLF has CSA verification of performance subjected to the same testing as the ILSF-A and B.

The ILNF does not require gaskets and is lightweight, thus it is considerably more economically priced. Cleaning the ILNF requires the whole unit to be removed, but in most cases, there are fewer bolts required to remove the whole unit then there are just to remove the elements from the ILSF-A&B models. The ILNF units can be manufactured out of stainless steel and exotic metals for a much lower cost than units with removable elements. Spare units can be purchased for marginally higher prices than spare elements allowing for two utilizable units if needed.

The ILNF is the practical way to go if you need protection at a below average cost.

Deflagration Detonation Flame Arrestor

AVAILABLE SIZES: 8’’

The Prism SS Deflagration Detonation Flame Arrestor has all the same working characteristics of the ILNF with two exceptions. The first is reduced internal support required to handle an overdriven detonation, however all other flame fronts are easily contained and do not generate force. The internal components are identical to the ILSF-A, ILSF-B, and ILNF.

The DDFA’s second difference is that it has been subjected to and passed internal testing only. The DDFA is designed specifically to give adequate protection at a rock bottom price. Many of the crimped ribbon flame arrestors that are sold on the general market are false security and would fail dramatically if subjected to testing comparative to the DDFA. Through internal flare system testing, Prism has witnessed these failures. The DDFA is a combustion solution designed to take the place of the many crimped ribbon flame arrestors in the industry that are misapplied and are a liability if subjected to an event.

Offset Dual Flange (OSDF)

AVAILABLE SIZES: 8’’

The OSDF Prism SS Detonation Flame Arrestor offers the best quality and protection that you can buy in the following features: gasket integrity, flame propagation stoppage through the full flame front spectrum, having the longest continuous burn time rating, eliminating fluid traps, and guaranteed cleanability.

The OSDF incorporates dual flanges on the flame quenching element section to ensure that the proper gasket can be installed to accommodate critical conditions. The dual flange arrangement will remain intact during a severe continuous burn condition in which the downstream side of the Detonation Flame Arrestor gets red hot and can suffer from heat warpage and distortion. On the dual flange Detonation Flame Arrestor, the upstream flanges are not subjected to the elevated heat, so they remain intact and functional, keeping critical piping intact.

Offset Single Flange (OSSF)

AVAILABLE SIZES: 8’’

The Offset Single Flange incorporates all the working features of the OSDF except it does not utilize the dual flanges on the element section. It is manufactured with a machined gasket face on the element section, which is available for the OSSF and the OSDF.

The OSSF combustion solution was designed from an economic standpoint. Some applications call for exotic metals such as Hastelloy and Tantalum to be used for chemical attack corrosion resistant. Purchasing large diameter flanges using these types of materials can be very expensive, thus Prism has re-engineered these OSSFs to reduce costs, giving you superior performance at an applicable price.

Optimized Cleaning & Reconditioning.

The Prism SS Detonation Arrestor combustion tech was designed around the cleaning and reconditioning of the unit and has been extensively engineered and tested to do not just one job, but many. The unique grid assembly flare stack flame arrestor is a series of accurately and evenly spaced flat bars that are welded securely into the cell. The grid assembly also greatly improves the continuous burn rating, and acts as a protective guard for debris that may travel in the piping system.

The grid assembly of the arrestor is arranged so that it is cleanable and rebuildable, saving future maintenance expenses. Once the used element has been removed, it can be shipped back to the factory to be cleaned and checked. At the factory, the media is removed. Then the cell assembly is sandblasted, cleaning all debris from channels, surfaces, and housing. After blasting, a thorough inspection is done to assure that the housing is totally intact. Once the inspection is complete, the unit is then recharged with new alumina ceramic, sealed, painted, and put in stock.
