CaSO_4, the product of sulfur-fixation reaction, will decompose at the temperature higher than 1200℃ that commonly appears in combustion chamber of boiler, which negatively affects the desulfurization in combustion process.

A miscible displacement experiment of soil column was conducted to study the change of physical and chemic characters of the soil leachate under different CaSO_4 solution concentration levels.

We find twice that the channel is choked up by CaSO 4 in half month during test production with electric pump to HD4-20H well in HaDe petroleum field.

Study on fouling performance and optimization cleaning period of water cooler sets;

Status and trends of the fouling monitoring technology of cooling water;

Effect of fouling on heat transfer performance of heat exchanger;

Treatment of dirt on the fertilizer plant decomposition heater by washing agent SHYJ;

The dirt may be eliminated from quenching oil by means of the addition of modification and the result is notable.

this paper illustrates the substances, which cause dirt on the outside Wall of buildings.

The cleaning of scale in solution circulating system of MDEA decarbonizing;

During mercerizing, Ca2+, Mg2+ and HCO3- in water forms with OH- in the fabric into water insoluble Mg(OH)2 and CaCO3 which attach to the guiding roller and become calcium and magnesium scale, thus influencing the product quality.

The effect of different scale inhibitors [polyaspartic acid (PASP), 2-phosphono-1,2,4-tricarbocylic butane (PBTCA) and amino-trimethylene-phosphonic acid (ATMP)] on flow subcooled boiling he.
