Hydrogen sulfide absorber “Paragroup PS 1666” is a specially selected composition of formalin solution in alcohol or ethylene glycol. The absorber is designed to bind hydrogen sulfide and acidic mercaptans in oil and oil products, as well as in gas and water environments. The absorber is used at oil refining enterprises, at points of transshipment of oil products and crude oil in ports and at oil, gas and gas condensate production enterprises.
The absorber “Paragroup PS 1666” is produced in three grades A1, A2, M in accordance with the current technical conditions TU 2417-021-17423242-2009 with rev. 1, 2, 3, 4, 5, 6.
Used in services
Transportation of oil and oil products
The efficiency of the introduction of the absorber ” Paragroup PS 1666″ 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 50-60C before adding the additive greatly facilitates the action of the absorber. Depending on the specific conditions of use, the dosage of the absorber can vary from 4 to 10 g per 1 g of hydrogen sulfide.
In order to increase the contact time of the reagent with hydrogen sulfide (mercaptans), the hydrogen sulfide absorber should be supplied as early as possible to the system with the processed product. The reagent can be injected either continuously or periodically. 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.
