A specialty chemical manufacturer was looking for a way to remove HCI from its off-gas before it was discharged to the atmosphere. CR Clean Air designed and manufactured a system which uses two Jet Venturi Fume Scrubbers in series, followed by two Packed Towers in series. Intimate mixing of the gas stream and scrubbing liquid allows the Jet Venturi Scrubbers to remove 98% of the HCI and the Packed Towers to remove the remainder. The Jet Venturi Scrubbers collect 98% of the HCI while creating

A number of technologies were investigated. The concentration method using regenerative activated carbon was selected for this high flow low concentration application. It incorporates the CR Clean Air patent pending, Revaporative technology to reduce operating and capital costs.

PHOTOCIRCUITS manufactures printed circuit boards, primarily for automotive use in motor vehicle dashboards and personal computers with manufacturing facilities in Glen Cove, NY and Peachtree City, GA.

A contract sterilization service uses a single-stage scrubber to convert this hazardous gas to inert ethylene glycol

TO Sterilization Inc. provides contract sterilization services for hundreds of northern New Jersey customers, concentrating on spices and herbs, cosmetic ingredients, and medical supplies. Two of the largest ethylene oxide sterilization vessels in the world are in operation at their Parsippany, N.J., facilities. The company had to scramble in the mid-19

With the passage of the 1990 Clean Air Act Amendments, many chemical and metal industries and utility producers will now be required to further limit the amount of NOx (Nitrogen Oxides) produced. NOx is a precursor to ozone in the atmosphere, and is believed to be a major contributor to acidic deposition (acid rain).

Formation of ozone: NOx is produced in a variety of different processes, including combustion equipment, gas turbines, incinerators, ki

The ethylene glycol produced in the ethylene oxide scrubbing operation acts as an antifreeze to allow year-round operation.

Problem: A specialty gas producer was confronted with an EPA compliance problem in dealing with ethylene oxide (EtO). The chemical had been added to the toxicity lists of the U.S. EPA and the Occupational Safety and Health Administration (OSHA). Effective August 21, 1984, the OSHA standard for EtO limited exposure to a

Abstract: The problems with odor around a typical edible oil deodorizer are discussed in detail, and a three-step solution to eliminate these problems is presented. The three steps are a distillate recovery system which recovers most of the fatty acid in the deodorizer vapor discharge as a valuable byproduct, a closed loop barometric cooling water system which keeps the fatladen hotwell water out of the cooling tower by recirculating it back to the vacuum system af

New Solutions to Plant Problems:Soybean extraction at Land 0 ‘ Lakes, Inc., Sheldon, IA, is an energy- intensive operation. Beans must be cleaned, properly dried, tempered, cleaned a second time, fragmented, and heat-conditioned to increase smface area and distort cell walls. On the extraction side of the process, soybean flakes are extracted by repeated countercurrent percolation of hexane solvent in either a continuous or continuous-batch extractor. Energy demand for
