Used Oil Man­age­ment in Turkey and Turkey’s first Hy­dro-Treat­ment Re-Re­fin­ery Tech­nol­ogy at a Glance

-

To­tal Turkey Pazarlama, which has been op­er­at­ing in the lu­bri­cant sec­tor in Turkey for 30 years, has re­newed its ad­vanced oil anal­y­sis sys­tem ANAC se­ries. The ANAC sys­tem, which has been grow­ing with data from all over the world for 40 years and based on the data­base con­tain­ing more than seven mil­lion di­ag­noses, iden­ti­fies the ve­hi­cle or equip­ment prob­lems through oil anal­y­sis. It of­fers spe­cific solution rec­om­men­da­tions to help you find where the prob­lem comes from ( air fil­ter, in­jec­tion pump, cool­ing sys­tem…) and fix it be­fore it be­comes se­ri­ous.

De­vel­oped specif­i­cally for four sec­tors

TO­TAL has launched new ANAC anal­y­sis se­ries in or­der to meet its cus­tomers' needs in in­tracity and in­ter­city trans­porta­tion, agri­cul­ture and con­struc­tion ma­chin­ery sec­tors and to of­fer

New Reg­u­la­tion on Used Oils in line with EU Leg­is­la­tion

Turkey used oil man­age­ment reg­u­la­tion com­plies with laws of mod­ern coun­tries with most re­stric­tive en­vi­ro­men­tal agenda. Turkey gives the pri­or­ity to re­fin­ing ( re­cy­cling) of used oil over en­ergy re­cov­ery and in­sin­er­a­tion. The

It is pro­hib­ited to dis­charge used oils to soil, drainage sys­tems, in­ter­nal sur­face wa­ters, ground wa­ters, coastal wa­ters, or any sim­i­lar en­vi­ron­ment or to mix with liq­uid fu­els, to use or per­mit to be used as liq­uid fuel or to re­cover, in­cin­er­ate and/ or dis­pose of by us­ing in­ap­pro­pri­ate means and meth­ods.

Used oils must be col­lected and stored only tem­po­rar­ily and sep­a­rately at source, where ap­pro­pri­ate.

Used oils shall only be col­lected and trans­ported by au­tho­rized or­ga­ni­za­tions/ col­lec­tors. It is pro­hib­ited for any unau­tho­rized per­sons to col­lect, trans­port, re­fine, re­cover and/ or dis­pose of used oils.

Oil pro­duc­ers, au­tho­rized or­ga­ni­za­tions and those who are in­volved in ac­tiv­i­ties re­gard­ing the tem­po­rary stor­age, col­lec­tion, trans­porta­tion re- re­fin­ing, en­ergy re­cov­ery and dis­posal of used oils shall be jointly and sev­er­ally li­able for any loss re­sult­ing from en­vi­ron­men­tal pol­lu­tion and degra­da­tion caused by used oils.

In or­der to pro­duce high ef­fi­ciency base oils from

used/ waste lu­bri­cat­ing oils ( i. e. re- re­fin­ing), only those clean pro­duc­tion tech­nolo­gies which do not cause ad­di­tional pol­lu­tion can be em­ployed.

Ve­hi­cle own­ers must change the ve­hi­cle's en­gine oil at a en­gine oil change sta­tion hold­ing a valid per­mit is­sued by the rel­e­vant pro­vin­cial direc­torate.

Turk­ish Lu­bri­cant Mar­ket is one of The Big­gest in Europe but Reg­is­tered Col­lec­tion is fall be­hind…

Turk­ish lu­bri­cant and base oil mar­ket data es­ti­mates pub­lished by PETDER “Petroleum In­dus­try As­so­ci­a­tion”. Lu­bri­cant con­sump­tion of PETDER mem­bers, which was 464.635 tons in 2017, de­creased by 14% in 2018 and to­taled 410.579 tons. Turkey's to­tal de­mand of lu­bri­cants is given as 593.617 ton in 2018. Turkey is one of the bigest mar­ket in terms of Base oil con­sump­tion in Europe.

EU de­mand on base oil is about 3.7 mil­lion ton/ year. % 83 of base oil su­pllied by Crude Oil Re­fin­ing, % 17 of Base Oil is su­pllied by used oil Re- Re­fin­ing. Col­lectable used oil amout is 2.1 mil­lion ton/ year and % 88 of col­lected prop­erly in EU.

Turk­ish leg­is­la­tion is in line with the Euro­pean Union pro­ce­dures about used oil man­age­ment but on the other hand be­hind for col­lect­ing and in­cen­tives for the re- re­fin­ing. On the con­trary, only 13% of po­ten­tially col­lectable used oil is legally and reg­is­tered col­lected. % 87 of po­ten­tially col­lectable used oil is il­le­gally col­lected.

Since, there is a huge ope­ness in Turkey about reg­is­tered col­lec­tion, re­fin­ing of waste min­eral oil al­most all of the used oils col­lected is pro­cessed with sim­ple meth­ods and the “out­put” is sold as “mold­ing or tex­tile oil". This un­stan­dard­ized “oil out­put” con­sumed as fuel/ diesel.

De­hy­dra­tion: Re­moval of con­tam­i­nated wa­ter, gly­cols and fuel frac­tion ( gas oil)

Low Vac­uum Evap­o­ra­tion Sec­tion: re­cov­ery of Light Dis­til­late Oil form de­hy­drated oil by evap­o­ra­tion

High Vac­uum Evap­o­ra­tion: Re­cov­ery of Heavy Dis­til­late Oil by evap­o­ra­tion abd re­moval of spent ad­di­tives i. e. As­phalt

Oil- Wa­ter Sep­a­ra­tion: Sep­a­ra­tion of fuel oil from waste wa­ter by us­ing den­sity dif­fer­ence and use it as sec­ondary plant fuel

Wa­ter, gly­cols, sol­vents, fuel frac­tion and a light base oil frac­tion present in oil are evap­o­rated at about 230240oC and 200- 250 mm Hg ( abs) in De­hy­dra­tion Ves­sel . Heated oil from the shell & tube heat ex­changer is re­cy­cled back to this sec­tion for pro­vid­ing heat to this sec­tion. The va­pors are routed to con­denser. The oil and wa­ter ( aque­ous) phases are sep­a­rated in a spe­cially de­signed oil- wa­ter sep­a­ra­tor. Dry used oil is sent to the sec­ond stage of the plant – the first oil evap­o­ra­tion sec­tion.

Dry used oil feed­stock is heated to ap­prox­i­mately 280oC in un­der moder­ate vac­uum ( 10- 15 mm Hg- abs) in a spe­cially de­signed ver­ti­cal heat ex­changer to evap­o­rate a light base oil frac­tion from used oil. The oil from the moder­ate vac­uum evap­o­ra­tion sec­tion is sent to a stan­dard shell & tube heat ex­changer and then fur­ther heated in a sec­ond evap­o­ra­tor which op­er­ates at higher vac­uum ( 2- 3 mm Hg abs) and tem­per­a­ture ( 290oC). Al­most all re­main­ing lu­bri­cat­ing oil is evap­o­rated from spent ad­di­tives in the sec­ond evap­o­ra­tor. Hot ther­mal fluid is cir­cu­lated thor­ough jack­ets of the two evap­o­ra­tors and the shell & tube heat ex­changer. Spent ad­di­tives are re­moved from the bot­tom of the sec­ond evap­o­ra­tor as residue. This re- re­fin­ing residue is a saleable prod­uct as as­phalt flux or can be blended into heavy fuel oils. The evap­o­rated oil frac­tions are con­densed and sent to tanks for stor­age. Un­con­densed va­pors are pulled by vac­uum sys­tem and dis­charged at am­bi­ent pres­sure to an abate­ment de­vice such as a ther­mal ox­i­dizer. lu­bri­cat­ing oil, un­der cal­cu­lated con­di­tions of pres­sure and tem­per­a­ture in pres­ence of pro­pri­etary metal­lic cat­a­lysts. Af­ter the re­ac­tions are car­ried out in spe­cially de­signed re­ac­tors, the high- pres­sure gas is re­cy­cled back to the re­ac­tors.

Make- up hy­dro­gen is added to com­pen­sate for losses. The oil ( liq­uid) un­der high pres­sure is de­pres­sur­ized, stripped to re­move light hy­dro­car­bons ( naph­tha) and dis­solved gases, cooled and sent to stor­age tanks. The fuel byprod­uct is used as fuel in the process plant. The off- gas con­tain­ing H S, mer­cap­tan- like sul­furous com­pounds and

2 very light hy­dro­car­bons is sent to a ther­mal ox­i­dizer or an­other abate­ment de­vice.

Out­put Prod­uct of the Hy­drotreat­ment Re­fin­ery, out­put is “Group II+ Base Oil” with the yield of % 73 and low sul­phur, high vis­cos­ity in­dex and high sat­u­rates.

Con­clu­sion

Used oils are dan­ger­ous for en­vi­ron­ment and hu­man health if dis­posed im­prop­erly.

Used oils are not wastes. Used oils are feed­stock for the Base Oil Re- Re­finer­ies.

Vac­uum Dis­til­la­tion com­bined with Hy­drotreat­ment tech­nol­ogy is the most ad­vanced tech­nol­ogy for ReRefin­ing used oils to high value added base oil.

Turkey has 600.000 ton/ year lu­bri­cant con­sump­tion and has no Re- Re­fin­ery and mis­use of used lu­bri­cants as a diesel is very com­mon.

For the base oil pro­duc­tion; Used oil Re- Re­fin­ing pro­vides bet­ter ad­van­tages in terms of en­ergy sav­ing, high yield and ef­fi­cient use of nat­u­ral re­sources over Crude Oil Re­fin­ing

TAYRAŞ is the Turkey's first Re­fin­ery hav­ing Hy­droTreat­ment Tech­nol­ogy to process used oils.
