Figure 1 2 shows a typical process flow scheme of a 2-stage straight-through 3 Claus sulfur recovery unit (SRU). Acid gas from the acid gas removal (AGR) process, along with overhead gases from sour water stripping and a small amount of recycle from the tail gas treating unit (not shown), are burned in the Claus furnace with sufficient air or oxygen to produce an overall gas mixture with the ...
A process for the sulfuric acid catalyzed alkylation of C3-C5 olefins with isobutane is disclosed wherein the requisite mixing is accomplished by the use of eductors within the reactor. In addition the alkylate product is subjected to primary and secondary coalescers for removal of entrained sulfuric acid. The vaporized unreacted C4's are recovered as liquid by absorption and desorption in an ...

sulphuric acid that treat alkylation waste acid. The plants are usually located on the refinery site which avoids the need to transport the waste acid to the processing facility. A regeneration plant will also process spent acid from other nearby refineries. The acid regeneration plant can also process hydrogen sulphide (H2S) gas
A simplified block diagram for production of TDI is given in Figure 2.50. Most TDI produced in the world is from a three-step process as shown. It begins with nitration of toluene, which is subsequently hydrogenated to the polyamine. The last step is reaction of the amine with phosgene to make TDI.
Sulfuric Acid Process Figure 1 above is a typical flow diagram of the contact process for a sulfur-burning plant for sulfuric acid. As you can see, sulfur and air are brought in and burned to make sulfur dioxide (SO 2). The SO 2 goes through a series of gas cooling
QUESTION I Ethyl ether is made by the dehydration of ethyl alcohol (ethanol) in the presence of sulphuric acid at 140°C. A simplified block diagram of the process is provided in the figure If 87% conversion of the alcohol fed to the reactor occurs per single pass in the reactor, and taking a basis of 1200 kg/h ethyl ether, calculate: a) Kilograms per hour of fresh feed (10) b) Kilograms per ...

Acid gas from the AGR is sent to the sulfur recovery unit (SRU) to recover sulfur (alternately sulfuric acid) as a byproduct. Since CO 2 is removed and vented ahead of MeOH synthesis, carbon sequestration can be implemented by the addition of a CO 2 drying and compression system. Figure 1: Simplified Block Flow Diagram for Coal to MeOH
