Abstract: The invention relates to a process for producing phosgene by gas phase reaction of carbon monoxide and chlorine in the presence of a catalyst in a reactor that comprises a plurality of contact tubes arranged parallel to one another, which contact tubes are filled with the catalyst and around which at least one fluid heat transfer medium flows, a feed stream of a mixture of a chlorine input stream and a carbon monoxide input stream being conducted into the contact tubes and reacted to form a phosgene-containing product gas mixture, characterised in that the product gas mixture is discharged from the contact tubes at an outlet end of the contact tubes.

Abstract: The invention relates to a process for producing phosgene by gas-phase reaction of carbon monoxide and chlorine in the presence of a catalyst in a reactor which comprises a plurality of parallel catalyst tubes which are filled with the catalyst and around which at least one fluid heat transfer medium flows, where a feed stream of a mixture of a chlorine input stream and a carbon monoxide input stream is fed into the catalyst tubes and is allowed to react to give a phosgene-comprising product gas mixture, wherein the reaction is carried out at an area load of more than 2.75 kg of phosgene/m2s. The invention also provides a reactor for carrying out the process.

Abstract: A process for producing a hydrocarbon stream with reduced CS2 content, comprising contacting a hydrocarbon stream containing CS2 with a solid reactive CS2-scavenger which contains primary and/or secondary amino group-bearing hydrocarbon residues attached to a solid support, at a temperature in the range of from 0 to 300° C., and separating the obtained reaction product of and reactive CS2-scavenger from the hydrocarbon stream.

Abstract: A conveyor cleaning system includes a treating region, a processing region, and a conveyor belt traveling from the treating region to the processing region. A distributor positioned across the treating region deposits a film of ozonated water on the conveyor belt. In the processing region, the conveyor belt is exposed to soiling agents such as grease and other animal matter. A high-pressure rinser may be positioned over the treating section such that the distributor is positioned between the high-pressure rinser and the processing region. Ozonated water may be generated by a system including first and second tanks. The first tank is filled with ozone gas and water. After a predetermined time, undissolved ozone gas is released. The contents of the first tank are then transferred to a second tank along with more ozone gas. After waiting a predetermined time period, undissolved ozone gas is released from the second tank.
