Piyush, 

Last year closing rank for various branches in HBTU was

Bio-chemical Engineering  41580

Chemical Engineering  30316

Civil Engineering  30473

Computer Science & Engineering  18213

Electrical Engineering  27968

Electronics Engineering  25922

Food Technology  44703

Information Technology  21615

Leather Technology 43852

Mechanical Engineering 26602

Oil Technology  41167

Paint Technology  35339

Plastic Technology  42770

So you can clearly see you can't get CSE in hbti according to 2018 cut off. 

But the seats have increased this year so don't lose hope. You may get CSE there. 

Hope it helps.
