  • Introduction
    This defoamer is used for delayed coking unit. It can reduce the foam layer highness, extend coking time, decrease coke powder taken, protect exchanger and cold device and radial pump, put an end to catalyzer poisoning in the subsequent hydrogenation unit. It can also reduce coke powder sediment in the volatilization line and the fractionating tower so that to prolong safe production period.

    1. No silicon element, harmless to catalyst of hydrogenation unit.
    2. Less dosage, long using period, stable chemical compose.
    3. Fast defoaming speed and lasting antifoaming nature.
    4. No corrosion to metal.

    Physical and Chemical Properties
  • Description

    This agent is used for preventing scaling at the heat exchanger, reactor, and pipeline of hydrocracking unit in the refinery.


    a.It has no components(such as metal and so on)which have bad effects on the activity of hydrogenation catalyst, product distribution, and product properties.
    b.Low ash content , lest cause reduced porosity on catalyst bed layer, increased bed pressure drop .
    c. The injecting amount is less, but the scale inhibition rate is up to more than 92%.

    Technical Index
  • Description

    JAF-2 hydrofining scale inhibitor is suitable for preventing scale formation of hydrogenation heat exchanger in the oil refinery .

    1.There is no components (such as metal, etc.) in the scale inhibitor, which have bad effects on the activity of hydrogenation catalyst, product distribution, and product properties.
    2. Low ash content , lest cause reduced porosity on catalyst bed layer, increased bed pressure drop .
    3. Less adding quantity ,convenient to use, scale inhibition rate can reach more than 92%.

    Technical Indicators
  • Introduction

    This oil sludge scale inhibitor is a very effective agent to keep the oil sludge system from forming scale. It is suitable for oil sludge pipeline, heat exchanger, and it also has certain effect on getting rid of scale already formed , improving the efficiency of heat exchanger to allow the stable operation of this system,to prolong the operation cycle and reduce the downtime.


    1. The product has good dispersivity, it can effectively avoid the accumulation of catalyst powder, corrosion products and salt, etc., suspended in the oil sludge to control the increase and deposition of particles.
    2. It has antioxidant property to stop polymerization caused by oxygen.
    3. It has metal passivation property to stop or reduce catalytic dehydrogenation and oxidization reaction.
    4. It has corrosion resistance and surface modification feature.

    Technical Data
  • Description

    Delayed Coking Scale Inhibitor is applied to delayed coking unit, to delay the coke of radiation tube furnace, prolong the period of run.


    1.It has antioxidant properties and metal passivation function,can form stable complex with metal ions in the oil the residue ;
    2.It has cleaning and splitting function; once a small amount of fouling or corrosion products are formed, it can deter them to get together to limit the increase particle deposition;
    3.It contains anti-corrosion agent and film-forming agent, so that the metal will not be oxygen ed and corroded.

    Technical Indicators
  • Features

    1.The product has good dispersivity, it can effectively avoid accumulation of catalytic agent powder, corrosion products and salt, etc., suspended in the residuum oil, and therefore control the increase of particle in the residuum oil and deposition.
    2.It has anti-oxidizing property, it can form inertia molecule with the oxidized free hydroxyl group and can stop polymerization caused by oxygen.
    3.It has metal passivation property, and corrosion resistant property and surface modification feature.

    Technical Data
  • Features

    1.Stable performance, low toxicity, no smell and water soluble.
    2.High content of effective component, low consumption.
    3.Good atomization and dispersibility property.
    4.It contains rare-earth element, and can act as normal metal passivation agent , can also raise the activity of balanced catalyst.

    Technical Data
  • Features

    The product is composed by multi-component. Its main components are MDEA and some kinds of high-effective additives. It has higher activation and desulfurizing effect than N-methyldiethanolamine. Its desulfurizing selectivity, capacity for absorbing acid gas, stability, antifoaming ability and regeneration ratio are fairly better than N-methyldiethanolamine. It has good chemical stability, better resistance to oxidation, lower corrosiveness and lower freezing point. It can be used very conveniently.
