The paper presents a desorption-based method for treating a waste mono-ethanolamine (MEA) solution to extract hydrogen sulfide. The process is used in the associated petroleum gas (APG) treatment unit to remove hydrogen sulphide together with the MEA solution process of hydrogen sulfide absorption from the APG that comes from the well. Extracted hydrogen sulfide can be used to obtain elemental sulfur. The object of development is a stripper for APG treating to remove hydrogen sulfide.Such a treating system is, as a rule, unavailable separately from the absorber and represents an integrated system to treat APG from hydrogen sulfide. Thus, the work objective was to determine parameters, and develop and design desorption column where mono-ethanolamine purification from hydrogen sulphide occurs.The paper presents calculation of desorption column that allows us to close the treatment process, thereby ensuring the regeneration of the mono-ethanolamine solution through treatment by the desorption process. The waste amine is returned to the gas treatment process, and the extracted hydrogen sulfide goes to the Claus process for elemental sulphur production. The column calculation was performed taking into account chemical and thermal processes. The APG treatment unit option to extract hydrogen sulfide with further elemental sulfur produced through the Claus process has been obtained to solve this problem by using the APG as an industrial and domestic gas.

Mono Ethanolamine

The paper presents an absorption-based method to treat associated petroleum gas (APG) using the mono-ethanolamine (MEA) as an absorbent. Involving oiler’s specific data in the southern regions of Russia, an APG treating unit has been developed to take out hydrogen sulfide. The extracted hydrogen sulfide can be used to obtain elemental sulfur. The development object is a treating APG unit.The work objective was to develop an absorber for APG treating to take out hydrogen sulfide by means of regenerated MEA aqueous solution. The work was aimed at reducing environmental pollution when using associated petroleum gas as an energy utility.A plate-shaped absorber model was used. In this design, the liquid enters the upper plate, moves horizontally along the plates, from the overflow from the overlying one towards the overflow to the underlying one, and outlets through the lower part of the absorber.The paper offers an option of the unit for APG treating for removing hydrogen sulfide with the elemental sulfur further produced by the Claus process to solve this problem through using APG as an industrial and domestic gas.The work has involved a complete calculation of the two-component absorption process, a design calculation of the plate-shaped absorber, in particular, determination of the cowl wall thickness, a fitting selection, a calculation of the foundation bolts taking into account the wind load on the absorption column, a rationale for the option chosen, and a calculation of the complete desorption process.In entering the desorber, the absorbent undergoes a single liquid and vapour phase evaporation. To calculate a mole fraction of the stripping initial absorbent, as well as phase compositions, is used a Tregubov method.

Shell And Tube

The design requirements for a large shell and tube vertical heat exchanger (to be used in a sulfur recovery tail gas treatment unit) included startup, shutdown and upset conditions that would subject the exchanger to significant temperature changes. The exchanger was designed to the requirement of the ASME Boiler and Pressure Vessel Section VIII Division 1 [1]. A detailed analysis of the thermal profiles and related stresses was performed to confirm the use of a flexible tube sheet design. The heat exchanger uses high pressure superheated steam on the shell side to heat a low pressure process gas on the tube side. The heat exchanger was sized and thermally rated, using commercially available analysis software. The proposed design was analyzed by Finite Element methods that included both thermal and stress analysis. These evaluations confirmed that a flexible tube sheet design was satisfactory when using specific dimensions.
