Absorber of hydrogen sulfide and mercaptans Paragroup PS1782

The absorber of hydrogen sulfide and mercaptans “PARAGROUP PS 1782” is a specially selected water-soluble composition of the condensation products of amines with aldehydes of various concentrations. The absorber is designed to bind hydrogen sulfide and acidic mercaptans in oil and oil products, including residual oil products, as well as in gaseous and water environments at oil, gas, gas condensate production enterprises and at oil refineries, as well as at points of transshipment of oil products and crude oil in ports.

The absorber PARAGROUP PS 1782 is manufactured in accordance with the current technical conditions TU 2633-073-17423242-2012, rev. 1

Oil preparation


In order to increase the contact time of the reagent with hydrogen sulphide and mercaptans, ” PARAGROUP PS 1782 ” should be supplied as early as possible to the system with the processed product. The supply of the hydrogen sulfide absorber must be carried out using dosing pumps. However, in any case, intensive mixing of the reagent with the oil product must be ensured.


The efficiency of the introduction of the absorber of hydrogen sulfide and mercaptans ” PARAGROUP PS 1782 ” depends on the degree of distribution of the reagent in the medium of the processed product. This is especially important for viscous oil products (fuel oil, boiler fuels). Heating such oil products to 70-90 ° C before adding the additive significantly improves the effect of the absorber. Depending on the specific conditions of use, the dosage of the absorber can vary from 4 to 8 g per 1 g of hydrogen sulfide.
