Contamination of amine systems (Refer to Figure 1 on following page) results in operational and environmental challenges for the operator. Contaminants include: Particles such as iron sulfide with the feed, Heat stable salts, Surface active agents, Liquid hydrocarbon in the gas feed, Carboxylic acids formed from oxygen entering the amine system, Corrosion inhibitors and water treatment chemicals entering with makeup water and wash water

Industrial lubrication systems require close monitoring of the lubricating fluid to detect contaminants and prevent the resultant degradation of the fluid. Contaminants such as water and metallic fines are commonly monitored manually, requiring routine sampling and laboratory analysis.

If a fire, smoke or gas leak is detected in an industrial facility, prescriptive actions must be taken by the fire and gas safety system, as well as the process control system, to mitigate and control the hazard. Using a certified, documented fire and gas safety system that can communicate appropriate messages to the process control system during an event is vital to the safety of a facility and its occupants.

By itself, hydrogen is colorless, odorless, tasteless and nontoxic. But when even small amounts of this seemingly harmless substance mix with air, it morphs into a major fire hazard.

Alkylation is an important refining process in which light olefins (e.g. propylene, butylene) are converted into higher value gasoline blending components with improved octane and vapor pressure properties. Agar technology can be applied in the alkylation process in two fundamental categories.

The Agar Foam Detector can detect the presence of foam far earlier than a ΔP cell, pressure gauge or other technologies. The probe can initiate or increase the anti-foam chemical injection rate causing the foam to dissipate. As a result, the anti-foam chemical feed rate is optimized, reducing the operator’s overall chemical costs.

The Agar Foam Detector can detect the presence of foam far earlier than a ΔP cell, pressure gauge or other technologies. The probe can initiate or increase the anti-foam chemical injection rate causing the foam to dissipate.

Storage tanks containing hydrocarbon feedstocks, intermediates and finished products will, over time, accumulate a water layer in the bottom of the tank (exceptions are water-soluble hydrocarbons such as alcohols and ethers). Standard industry practice is to periodically drain the water from storage tanks so that the water does not adversely impact specifications of the hydrocarbon.

By contacting hydrocarbon with mercaptan rich caustic, a very stable emulsion may form in the UOP Merox process. This causes significant quantities of caustic to carry over with the product.

Common techniques for foam detection include: DP gauges, capacitance probes, guided wave radar, electromagnetic radiation, neutron-backscatter, sonic echo devices, flow meters, and sight glasses. Most of these do not offer early foam detection.
