Engineering hub that routes H2S, SO2, HF, HCl, chlorine and ammonia loads to the right scrubber chemistry, materials and safety boundary – via one pollutant decision matrix, three screening questions, and a worked three-stream routing example.
Route semiconductor, glass, plastics extrusion, and automotive exhaust to the right abatement device with a process-by-process matrix.
Use a six-stage decision matrix to identify where your wet scrubber project stands, open the right guide, and prepare the data your supplier needs.
HF scrubber selection guide for engineers: how HF enters the gas stream, which wetted-zone materials survive the service, when wet vs dry is the right route, and how to handle fluoride-bearing wastewater under the applicable state NPDES permit.
Cyanide electroplating exhaust is a segregation problem before it is an airflow problem. This guide covers why acid and cyanide lines cannot share an exhaust system, what OSHA 1910.94(d) requires for open surface tanks, and the ten design inputs a qualified engineer needs to sign your segregation and exhaust basis.
Automotive manufacturing exhaust is six pollution problems wearing one label. This guide routes paint, pretreatment, welding, machining, battery, and plastics exhaust by pollutant form to a wet scrubber, filter, oxidizer, or carbon adsorber—with a verdict that is allowed to be not a scrubber.
A wet scrubber fits plastics extrusion exhaust when soluble acid gases or capturable particulate dominate, and it does not when poorly soluble VOC or condensable-heavy streams are the load. This guide walks the fit test — source characterization, pollutant form, five criteria, decision matrix — and ends with a source characterization data sheet to send to EHS and your vendor.
A scrubber room is more than the tower footprint: the input list covers envelope and clearances, access, drainage and containment, ventilation, chemical storage, utilities, lifting and code review. This guide builds the Facilities Input Data Sheet your designer, contractor and scrubber supplier confirm before design.
Incinerator exhaust is not boiler flue gas: SO2 arrives with HCl, fine particulate, and metals at temperatures that require a quench stage. This guide maps furnace type and feed to your acid load, matches your unit to the applicable NSPS or permit limit, and builds the design input sheet — liquid-to-gas ratio, pH, pressure drop, materials, monitoring — that a vendor needs to quote an SO2 scrubber for incinerator exhaust.
Wet scrubber rebuilds and retrofits are a shell-life decision, not an age decision. This guide walks a facility owner from the first degradation signals through a nine-point asset inspection to a repair/rebuild/replace decision matrix, then turns the branch into a supplier-ready scope definition with design inputs and acceptance criteria — without promising fixed service lives or guaranteed savings.
Glass furnace exhaust carries solid and condensable particulate, sulfur and halogen acid gases, and trace metal HAPs, and it is not always a wet scrubbing problem. This guide routes the stream between multi-stage wet scrubbing, dry sorbent injection, and filtration against EPA’s AP-42 factors and the NSPS and NESHAP limits, then sizes the multi-stage train of quench, venturi, packed tower, and demister from eight inputs a supplier needs, with a worked example for a container glass furnace.
A packed bed scrubber for semiconductor acid-gas exhaust is a counter-current wet scrubber that absorbs HCl, HF and other acids from etch, wet-clean and CVD tool exhaust. This guide covers which of the four fab stream classes belong on a packed-bed scrubber, how the tower captures acid gas and when it fits, HCl versus HF design differences, normal-versus-peak design basis, tower parameters, material and temperature boundaries, demisting, redundancy, monitoring, and a worked example that ends in a 12-field design input sheet you can hand to a supplier.
Wastewater tank vents and leachate exhaust can carry H2S above safe odor and exposure levels, so treatment starts with quantification, not equipment choice. This guide covers where vent gas comes from, how to estimate flow and H2S peaks, when a caustic wet scrubber, impregnated activated carbon, biological, or liquid-redox system fits, the six design inputs a vendor needs, a worked 150-cfm example, and inlet/outlet monitoring for acceptance.
Run a wet scrubber installation in five phases: site readiness, receiving, piping and instrumentation, leak testing, and commissioning — with a check item and an acceptance action at every step. This checklist covers foundation and utility verification, incoming inspection, P&ID instrument verification against EPA monitoring indicators, leak testing before energizing, pre-start checks, and commissioning acceptance against design criteria, with a ten-week worked example.
